[ ] () ========================================== Welcome to Central Office News! The purpose of this publication is to aid the experienced and informative hackers and phreaks as well as serve the newcomers a guide on how to succeed in the H/P Community without getting busted,ragged on, or being labelled LAME! In General, Im writing CON for all you HARDCORE hackers out there! Most of the articles will be taken from hardcopies. hahahaha Before I continue with the issue, Id like to make a couple of points. 1. My handle is Network Operator 2. I will write most or all of the articles. So unlike most h/p mags, I am not depending on people to contribute articles and I do not really intend for this to be the best journal out there. What Im doing is just releasing information(some interesting and some general)that would otherwise be thrown in the trash. Everybody at one time or another has found something in the trash that would not otherwise be known about if it wasnt found in the trash. So if you like what you see, then im happy. If not, then Im still happy because Im putting forth an effort to get this info out to you. Ok, CON will basically deal with Bell's Newest Services, Technological Advances, Technical Information, H/P tips, Switching Information(OF COURSE!) I may even list a Bell Conference line or two.. You never know what you will see in CON! Since this is a first issue, I will explain some concepts on Trashing and some good tips on how to trash smartly. I will have a net-mail address set up and possibly a 1-800 VMB for your comments and suggestions or if you just wanna tell me to piss off! I will look forward to hearing from you all! Index ===== 1.

Introduction to Overseas Packet Switched Networks 8. News and Current Events CON Issue 1 Article 1 =========================================================================== Trashing: The Do's and Dont's Exactly what is trashing? Trashing is a term which describes the practice of individuals rummaging through a company's dumpster in hopes of finding printouts of computer dialups,logins and passwords. This is a great and probably the best way to access computers with useful data. Everybody Im sure already knew this.. But the first part was for beginners so they know whats up. There are certain guidelines to follow when going out on a trashing run. 1. Select a target company or location. This is extremely easy as most companies addresses are in the phone book. 2. Scope out the company or location. Drive to the location during the day and check out what type of physical security they have. Remember, all you want is the trash, but you must check for two things first. 1. Is the dumpster inside a fenced area? 2. where is the dumpster in relation to the Builiding's doors and windows? The reason for these 2 things is important because they determine whether or not you can get to the dumpster safely. If the dumpster is inside a fenced area, then my advice is to forget it and move on to one without a fence. Reason:It is a Class B Misdemeanor in most states to Tresspass on Property. A Fenced-in area spells out DO NOT ENTER There doesnt have to be a NO TRESSPASSING sign posted. If you climb over a locked fence, your tresspassing. OK, if the dumpster is behind the building or otherwise not fenced-in, then you must check for NO TRESSPASSING signs. Remember your on Private Property, So the Police could still get you for Tresspassing if there are signs posted. Also, know the LAW! If a cop threatens to arrest you for trashing and no signs are posted, quote him the law.. He cant arrest you for taking trash, Once a company throws something away, it is no longer theirs. So your not stealing nothing. If the dumpster is close to a window or door, you will need to exercise caution. Reason:Your main priority is to remain unseen or invisible. The reason for this is being seen by anyone can alert the company that your going through their trash and that is not good. As long as nobody sees you, you should have no problems. 3. Know your police patrol times. The more you know about when your police patrol will save you any nervous explanations of your activities. 4. Dont be paranoid. being paranoid about trashing will only hinder your performance. Being paranoid can cause you to get careless and also to try and get the procedure done quickly. This may involve opening a dumpster slide-door too quickly that it makes noise. This is something that you do not want to make too much of. Its important to be cautious but paranoia will only make your trashing experiences hectic rather than fun.. 5. Mission Accomplished Leave Site. Once you have your prize, why wait around for something to happen as things usually do. Leave the site as soon as you have your trash inside the vehicle. Well thats it for now, be sure and let me know of your trashing experiences..first timers and seasoned. If I get enough responses we might have a section on Trashing Adventures where one individual describes an interesting trash run. I know Ive had some.. So long and happy trashing! Network Operator CON Issue 1 Article 2 =============================================================================== SWBT New Billing Services for Companies Source Date:Feb 20, 1992 Those bulky paper bills large business customers receive from SWBT could be replaced by a single floppy disk. A trial of Bill Plus* service begins this week with 12 cutomers. Cramming all that billing information often filling several hundred pages_______On one diskette is a welcome change for many customers, said Kathy Stoplos, manager-systems support. "In researching customer billing needs, we discovered that some customers spend hours and in some cases days, manually keying our billing information into their computers," Stoplos said. "Bill Plus completely automates that function." SWBT plans to file tariffs for Bill Plus after the trial results are evaluated. Customers using the system would pay a fee to establish the service, which includes necessary software developed by the customer services support group in the information systems department. The software will provide customers with several useful features, said Laura Craver, area manager-finance customer service. "It will allow them to graphic analyses and historical trending,"(whats this? BELL pushing their version of a graphics report program in the form of a new service?? gimme a break! wonder how much you have to pay for that software...ed.) Craver said. "It also enables them to export the data to a different file." For SWBT, Bill Plus will cut postage costs. A traditional 250-300-page paper bill for a large business customer costs around $6 to mail. Since all that information can fit on one Bill Plus diskette, the mailing cost drops to 98 cents.(Once again we see what bell's real goal is.. to save more money! they make so much off consumers you would think they could afford to pay a lousy $6 to mail the bill..ed.) Bell also introduces another new billing service EDI. Imagine receiving a phone bill so big that it comes in a box instead of an envelope. That's the case for many large business customers. But SWBT is trying to make the delivery of those bills less cumbersome. One method is Bill Plus* service. Another is Electronic Data Interchange (EDI), which allows SWBT to transmit the billing information directly to the customer's computer.(I see possibilities here...ed.) Requirements are a communicationss link and translation software supporting national standards. "With EDI, the larger the scale, the greater the benefits," said Bernie Ralph, systems specialist. "You do away with the paper bill. The billing information instead goes right into the customers'accounts payable."(At least eliminating the paper bill will help the enviorment.ed.) SWBT is now testing EDI with eight large business customers. During the trial, the telco is working with national standards groups who will decide exactly what the electronic phone bill will look like. "All of this is geared to speeding up the bill delivery process, and so far, the trial customers are satisfied," Ralph said "In fact, several of them have increased the number of accounts since we started." AT&T, one of those customers, started the trial with about 70 accounts transmitted via EDI. Now they're up to over 3,000 accounts. Like Bill Plus, EDI offers benefits for both customers and SWBT, Ralph said. "For us, it reduces paper handling and postage. It also gets the bill to the customer faster and thus, we can get paid faster." EDI is expected to move out of the trial stage and into full production status by the middle of this year. CON Issue 1 Article 3 ================================================================================ Conklin Instrument Corp. Presents THE MODEL 323 ISSUE 2 ALL-RATE DSO-DP The Conklin Instrument Corp. Model 323 Issue 2 All-Rate Digital Signal Zero Dataport (DSO-DP) with Secondary Channel is designed for use in the Digital Data System (DDS) network and in "DDS like" networks. This unit is designed to be installed in an AT&T Technologies D4 channel bank or SLC -96 subscriber loop carrier system shelf replacing the usual analog channel unit. Use of the unit provides a method of extending DDS service to a customer location from any serving central office having D4 channel banks or SLC-96 carrier systems connected via T-carrier facilities toward a DDS Hub Office. The Model 323 All-Rate DSO-DP provides the interface between the 1.544 Mb/s bit stream of the D4 or SLC-96 terminal common equipment and the DDS DSO 64 kb/s bipolar signal. The DSO signal may then be cross-connected to multiplex equipment in a DDS Serving Office or connected in a tandem arrangement to another D4/SLC-96 channel bank in a DDS Tandem Facility Office if company policies permit. The Mode 323 supports all standard DDS data rates(2.4,4.8,9.6, 19.2,56 and 64 kb/s)and also supports Secondary Channel operation(except at 64kb/s). Other features include optional Zero Code Suppression,Error Correction, and choice of Latching and/or standard OCU (HL96NY) Loopback. The Conklin Model 323 All-Rate DSO-DP may be used as a direct replacement for any AT&T compatible DSO-DP unit. The Model 323 is electrically and mechanically compatible with D4 and SLC-96 channel bank shelves without modification of equipment or existing office wiring. DDS timing is provided by the office composite clock via the OIU-2 optioned for external timing. The front panel of the unit has LED status indicators and test jacks permitting evaluation and testing of the dataport circuit. Power requirements are minimal permitting maximum utilization of the D4 or SLC-96 channel bank shelf assembly. FUNCTIONAL DESCRIPTION Dataports allow DDS service, or similar digital services, to be extended to customers that cannot easily or economically be connected directly to a DDS End Office. The Conklin Model 323 DSO-DP permits the use of D4 and SLC-96 channel banks to provide DDS type service. Figure 2 shows a typical DDS Dataport application utilizing the Model 323 DSO-DP at a DDS Hub Office and any one of the companion Models from the Conklin Model 322 Series OCU-DP at the Serving End Office, often called a Dataport End Office. Figure 3 shows a Tandem Office application used to extend DDS service to the Serving End Office. Both are typical applications and illustrate the use of the Conklin Model 323 DSO-DP and Conklin Model 322 Series OCU-DP modules installed in a D4 or SLC-96 channel bank.

DDS END DDS HUB OFFICE OFFICE The customer's DDS 4-wire metallic loop directly interfaces any one of the Conklin Model 322 Series OCU-DP modules installed in a D4 or SLC-96 channel bank located near the customer. Customer data is converted to a 64 kb/s digital signal which interfaces the D4 or SLC-96 terminal common circuitry. This signal occupies a single time slot of the 1.544 Mb/s DS-1 bit stream. Two time slots are required for 56 or 64 kb/s circuits employing error correction. The data rate in the figure above is 1.544 Mb/s. This data rate is designated DS-1 and is subdivided into 24 channels of 64 kb/s data, designated DS-0. The Serving End Office is connected to a Tandem Office or directly to a DDS Hub Office by a T-carrier facility. The Model 323 DSO-DP is designed to be installed in a D4 or SLC-96 shelf located at a DDS End Intermediate, or Hub Office. The unit electrically interfaces the common circuitry of the shelf. Transmission of customer data occupies a single time slot of the DS-1 signal transmitted via a T-carrier system. This data is converted by the Model 323 to a DSO-A bipolar 64 kb/s signal for cross-connection to another D4 or SLC-96 channel bank, or to T1 Multiplex equipment for transmission toward the DDS Hub Office. The unit also performs the reverse function. The Model 323 DSO-DP is designed to provide a choice of loopback and test access options. There are three products in this family:List 1,List 2, and List 4. The Model 323 List 1 and List 4 units are designed to detect and respond to either the standard DDS-OCU Loopback (HL96NY) or Latching Loopback. The Model 323 List 2 unit is designed to detect and respond to only the standard DDS-OCU Loopback (HL96NY) Tables A and B show the OCU (HL96NY) Loopback and Latching Loopback codes sequences respectively. The loopback code sequences may be transmitted from the DS-O or DS-1 directions. Loopback commands detected from the DS-O side will implement a DS-1 Loopback and commands detected from the DS-1 direction will implement a DS-O Loopback. The List 1 unit may be optioned to a permit either or both loopback types to be enabled or disabled. The List 4 units have a special front panel test access configuration that reverses the Near/Far logic test direction from that of the List 1 unit. In all other respects, the List 1 and List 4 units are identical. Detection of the Latching Loopback code sequence will place the List 1 or List 4 units in a latched loopback mode which will remain in effect for the List 1 and List 4 units until the correct loopback release code has been detected. Front panel LEDs "TEST" and either "DSO LB" or "DS1 LB" will be illuminated to indicate the loopback point. Latching Loopback differs from the standard DDS- OCU Loopback in that restrictions on the type of data transmitted are eliminated. Detection of standard OCU Loopback code will implement the HL96NY Loopback and illuminate the front panel LEDs "TEST" and either "DSO LB" or "DS1 LB" to indicate the loopback point. Once looped, detection of a short burst of all ones will release the loopback at the DSO-DP and cause the downstream dataport to enter loopback. The downstream dataport may be another DSO-DP in a tandem configuration or an OCU-DP. The front panel LED "TEST" will remain ON when the loopback is at a downstream dataport. All other front panel LEDs will be OFF. Thus, the loopback point may be electronically "stepped" from the Loop- Side Interface module (Conklin Models HL96NY and 222), to each Conklin Model 323 DSO-DP, and finally, to the OCU-DP. Removal of the OCU Loopback code from the data stream will release all loopbacks and return all dataports to the normal operating mode. The OCU Loopback option must be turned OFF for 64 kb/s Clear Channel circuits. Additional operating features of the Model 323 All-Rate DSO-DP include Secondary Channel Capability, Error Correction and Zero Code Supression. Front panel LEDs provide a visual indication of loopback status and an idle circuit condition. The following panel indicators are provided: 1)TEST (Green LED) 2)DSO LB (Loopback) (Green LED) 3)DS1 LB (Loopback) (Green LED) 4)IDLE CKT (Yellow LED) TABLE A.

(2) Sequence number 5 in the above table is used only when multiple DSO- DP's exist in a tandem configuration. In this case, sequence 5 should be executed (N-1) repetitions where N is the number of DSO-DP's that lie between the test center and the desired loopback point. This step should not be executed for circuits with only one DSO-DP. (3) After 30 or more LBE Bytes are received, any code can be interleaved between the remaining LBE and FEV Bytes to complete the Latching Loopback sequence. Therefore, at least 30 Bytes of TIP should precede and follow all procedures to clear all modules within a system configuration. (4) The Latching Loopback of the Model 323 Issue 2 List 1 and List 4 units do not have a time-out feature. Once it is activated, it will stay activated until the proper clear code is received. Test access is provided by bantam jacks on the front panel. These jacks permit test signals to be transmitted to, and received from, the DSO-0 or the DS-1 directions and may also be used to implement a manual loopback with a bantam-to-bantam patch cord. The Conklin Model 323 DSO-DP supports all error correction modes compatible with existing dataport sub-rate 56 and 64 kb/s data requirements. Option switches are provided permitting error correction configurations that are compatible with D4 and SLC-96 operating modes. Zero code supression, normally enabled, may be optionally disabled allowing unrestricted 56 kb/s Secondary Channel data and 64 kb/s Clear Channel data to be transmitted over T-carrier facilities. CIRCUIT DESCRIPTION The following circuit description helps to emphasize the overall performance of the DSO-DP Unit. COMMON CIRCUITS The Model 323 DSO-DP, when installed in a D4 or SLC-96 channel bank shelf, will interface the common circuitry associated with the channel banks. The interface provides access to the DS-1 PCM Bus, the integrated 64/8kHz Clock, Channel Select Timing signals, and the Out-of-Frame signal. All interface signals are provided at the card-edge connector of the Model 323 DSO-DP. Modification of the D4 or SLC-96 channel bank shelf is not required. CLOCK BUFFER This circuit is common to all other circuits of the DSO-DP and generates all timing signals required for rate matching and synchronizing customer data to the DDS Reference Clock. These timing signals are derived from the office scomposite clock supplied to the common circuitry of the D4 or SLC-96 channel bank. ERROR CORRECTION CIRCUITS Use of dataports to provide DDS service over T-carrier systems used primarily for analog service may require the use of error correction techniques to meet established DDS error rate performance objectives. Two error correction techniques are utilized in the Model 323 All-Rate DSO-DP module. A repeat-of-five majority-voting scheme is used for DDS sub-rate service and takes advantage of the redundancy of the sub-rate data. For 19.2 and 56/64 kb/s data rates, a shortened Golay code is used to generate a parity byte which is transmitted along with the data byte. Error correction at 56/64 kb/s requires two 64 kb/s data channels occupying two of the DS-1 time slots, one for customer data and the other for the parity bit stream generated by the Error Correction Encoder. DDS NETWORK TO T1 FACILITY PATH BIPOLAR TERMINATOR The DDS 64 kb/s balanced bipolar digital signal from the DDS network, via the DSX-0A level cross-connect, is transformer-coupled to the input of the Bipolar Terminator. This circuit converts the bipolar input signal to a logic level signal for interface to the Loopback Code Detection circuit. LOOPBACK CODE DETECTOR This circuit will detect loopback codes received from the DS-0 direction, usually transmitted from the STC. A loopback option switch may be set to enable or disable either the standard OCU Loopback or Latching Loopback on the List 1 and List 4 units; or only the standard OCU loopback on list 2 units. The circuit is transparent to all other loopback codes. Detection of the appropriate loopback code sequence received from the DS-0 direction will implement a logic level loopback at a point internal to the unit. Front panel indicators "TEST" and "DS1 LB" are controlled by this circuit and will be illuminated when this loopback is in effect. ZERO CODE SUPPRESSION This circuit block monitors data transmitted from the DDS network toward the T1 facility. The circuit will substitute the Unassigned MUX Channel (UMC) code for a byte of data containing all 0's An option switch permits the Zero Code Suppression function to be disabled. Normally, this option should be enabled. Disabling of Zero Code Suppression allows for unrestricted transmission of 56 kb/s secondary channel data into the T1 facility when B8ZS encoding becomes available for D4. Zero Code Suppression should also be disabled for 64 kb/s Clear Channel operation. ERROR CORRECTION ENCODER The Error Correction Encoder circuit monitors data transmitted toward the T1 facility and will implement the appropriate correction scheme based on the data speed and the setting of the Error Correction option switch. This switch selects sub-rate 19.2 or 56/64 kb/s Error Correction. Several 56/64 kb/s error correction modes are provided to maintain compatibility with both D4 and SLC-96 channel bank operating modes. Error Correction may also be disabled. TRANSMIT RATE CONVERTER This circuit converts the DDS 64 kb/s byte-encoded signal to the format required for interface to the PCM Bus and D4 or SLC-96 common circuitry. Clocking of the data is controlled by the channel bank common circuitry. The data is clocked into the proper time slot of the DS-1 bit stream. Clock signals from the Clock Buffer retime and synchronize the data to the DDS Bit Clock. The output signal from this circuit connects to the Tri-State Buffer which interfaces the DS-1 PCM Bus associated with the common circuitry of the D4 or SLC-96 channel bank. T1 FACILITY TO DDS NETWORK PATH RECEIVE RATE CONVERTER Byte-encoded 64 kb/s data received during a single DS-1 time slot is gated to the input of this circuit by Channel Select timing signals. The circuit converts the data to a 64 kb/s DS-0 logic level signal. ERROR CORRECTION DECODER This circuit monitors data received over the T1 facility. The circuitry detects and corrects bit errors by application of the appropriate error correction scheme for the data rate in use. The error correction function is configured for sub-rates 19.2 or 56/64 kb/s by the option switches. OUT-OF-SYNC CODE INSERTION Failure of the T-carrier span line or the D4/SLC-96 channel bank will activate the Out-of-Frame alarm associated with the channel bank common circuitry. This alarm signal interfaces the Out-of-Sync Code Insertion circuit which will generate and insert in the data bit stream the Out-of-Sync Code for transmission toward the DS-0 direction. LOOPBACK CODE DETECTION This circuit will detect loopback codes received from the DS-1 direction. The circuit operates in the same way as the Loopback Code Detector discussed previously. Loopback option switches may be set to enable or disable either the standard OCU Loopback or the Latching Loopback as discussed earlier. The circuit is transparent to all other loopback codes. Detection of the appropriate loopback code sequence received from the DS-1 direction will implement a logic level loopback at a point internal to the unit. Front panel indicators "TEST" and "DSO LB" are controlled by this circuit and will be illuminated when this loopback is in effect. BIPOLAR DRIVER The 64 kb/s byte-encoded data signal received from the T1 facility for transmission toward the DDS network interfaces the Bipolar Driver circuit and is converted to a DS-0 64 kb/s balanced bipolar signal which is transformer- coupled to the DSX-0A cross-connect point. Well there ya have it, An inside look at some of the digital equipment that operates in your local CO. I hope this file has been helpful or insightful to any of you that found it interesting. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CON Issue 1 Article 4 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ HOSPITAL CALLING Im sure many of you have tried to SE the PBX dialup from a hospital. Its a well known fact that most big hospitals have them. This is not a new idea but an old one that is being revived for what its worth. Instead of calling up your local hospital and trying to get the dialup, why not make a call off the operator's lines... sound hard? no its not really that hard.. All you do is call up a hospital and speak to the switchboard attendant. First you might try posing as a Phone Co. official and SE info about her PBX equipment,extensions, what type of lines/trunks they have coming in and out. Then after that is accomplished, call up the hospital as Joe Blow and ask to be transferred to a valid extension in the hospital like X-Ray. Tell whoever answers the phone that your Joe Blow in another valid department like Maternity and say your having trouble with getting an outside line or ask them to look for a non-existent person. In either case they will not be able to help you. Right before you end the conversation, ask them to transfer you back to the operator. Now when you get the operator again, Tell them your Joe Blow in X-ray (because thats what extension will show up) and that you need an outside line because your 9 key will not work or some other good excuse. 9 times out of 10, the operator will give you an outside line if its within her power to do so. after that you can dial any local number or 800 numbers. You wont be able to dial long distance because hospitals and hotels have a special screen code on most IRC's that will not allow them to bill to a hospital or hotel trunk. But you can get around that by saying you want to make a call and bill it to your AT&T calling card or etc.. you might try other local services like 1411(information) or 0 for operator to accomplish any other task you might wanna perform. The reason you must first transfer extensions is that when you first call, you show up on the incoming line from outside. The PBX attendant knows this and will not give you an outside line. But once your call is bridged to an extension then back again, it doesnt show you as coming from outside the hospital. Please keep in mind that for this trick to work, it will depend on how Advanced the hospital's PBX equipment is. Network Operator +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CON Issue 1 Article 5 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ BELL COMPUTER FACILITY PHYSICAL SECURITY (Part I) This file will give you an idea of what Bell will do in order to ensure security of their computer systems from all types of harm and destruction. This first Part covers Fire Controls. FIRE CONTROLS COMPUTER ROOM LOCATION A computer room should not be located immediately above,below, or adjacent to parking garages,loading docks,cafeterias,test laboratories,major power rooms or other potentially hazardous areas. For computer rooms located above the sixth floor, arrangements should be made with the local fire department to ensure that fire fighters can manage fire fighting equipment at floors 7 and above. COMPARTMENTATION Walls enclosing a computer room should extend from the concrete slab of one floor to the slab of the next floor and be of one-hour fire rated noncombustible construction. This also applies to walls enclosing magnetic media operations rooms and magnetic media operations libraries. Doors to a computer room should be Underwriter's Laboratories (UL) listed Class C doors thats are 3/4 hour fire rated. This also applies to doors to magnetic media operations rooms and magnetic media operations libraries. Walls enclosing a magnetic media library should extend from the concrete slab of one floor to the slab of the next floor and be of two-hour fire rated noncombustible construction. Doors to a magnetic media library should be UL listed Class B doors that are 1 1/2 hour fire rated. A magnetic media is library protected by a Halon 1301 flooding system or water sprinkler system: its doors and walls only have to meet requirements for regular computer rooms. Computer rooms should not have windows in perimeter walls. If this is not possible, the windows should be supported so that they have sufficient strength to withstand high levels of impact(e.g. two panes of glass; glass supported by wire, grilles, or LEXAN) The windows should also contain the necessary insulation to protect the thermal enviorment of the computer facility. It is recommended that doors within walls that enclose any type of computer room be windowless. Exceptions, such as wired, are allowed, with size restrictions. Ceilings for a computer facility should be of the type that does not dust or flake, Ceiling material should be constructed of noncombustible material or be UL listed with an acceptable flame spread. Ceiling height for raised floor areas should be 8-10 feet to provide adequate ventilation and machine clearance. Raised Flooring within the computer facility should be 18 to 24 inches from the floor slab to the top side of the floor panels. These panels should be constructed of concrete, steel,aluminum, or metal-enclosed wood, and be electrically conductive to minimize static electricity problems. Sub-flooring and structured floor should be constructed of reinforced concrete, and the floor should not be covered with any type of floor covering materials. The support assembly for the raised floor should rest directly on the concrete slab. Occupied/unoccupied cable holes or cable slots in floor slabs and walls should be fire-stopped and sealed. Shaft enclosures between two or more successive floors should be totally enclosed. Fire dampers should be listed or built in accordance with UL555 requirements. Storage rooms should not open into any type of magnetic media facility. Storage rooms (where combustibles (e.g. chemicals,paper)are stored) should be located outside computer rooms. A storage room can open into a computer room(or can border a magnetic media facility) if the wall seperating the storage room from the computer room is the one-hour fire rated perimeter wall of the computer room(two-hour with regard to a magnetic media library not protected by sprinklers or a Halon 1301 flooding system), and if the door between the storage room and the computer room is 3/4 hour fire rated UL listed Class C (non-applicable for a magnetic media facility). Computer facility storage rooms, and C.E. rooms containing electrical machinery, should be provided the same protection(e.g. fire detection and suppression) required for a computer room. Areas with large amounts of combustibles should not be part of computer rooms(no shit ed.) Equipment staging areas should be located outside computer rooms. The areas should meet computer facility fire control and access control requirements and equipment vendor enviormental standards. Boxes should be immediately removed from equipment brought into a computer room from a staging area. The boxes should then be immediately removed from the computer room. All air duct insulation,adhesive,linings, and/or coverings should be noncombustible or UL listed with a flame spread rating of 25 or less and smoke developed rating of 50 or less. Air filters for use in air conditioning systems should be of approved types that will not burn freely or produce a large volume of smoke or other objectionable products of combustion when attacked by flames. FURNISHINGS AND MATERIALS Building and finish materials of a computer room and related areas including walls,floors,partitions, acoustical treatment, insulation, raised floor supports, suspended ceilings, floor covering materials, and other construction, should be noncombustible or UL listed with a flame spread of 25 or less and smoke developed rating of 50 or less. Offices should not be maintained in computer rooms because of flammable materials normally maintained in offices( and for access control purposes). If offices must be maintained in computer rooms, they should be kept to a minimum, and office materials especially paper products should be carefully controlled. Cubicle walls and office furniture should meet noncombustibility requirements pertaining to materials used in equipment spaces. Carpet should not be used in a computer room. Where carpet is used for noise control, or if it can be justified on the basis of reduced maintenance, then it can be used in the computer room. It should be of the type that minimizes the effects of static electricity. It is recommended that only trash receptacles that are UL listed or Factory Mutual (FM) approved to be used in computer rooms (which should also include the COM Center in data centers). Areas of data centers such as Print- Punch,Bursting,Bill Mailing and Distribution, etc. are exempt from this recommendation at the present time because there are no UL listed or FM approved trash receptacles on the market that can reasonably replace the carts,dumpers,tilt trucks, tubs, etc. used in these areas where waste paper is generated in high volume. The carts,dumpers,tilt trucks,tubs, etc. are not to be principally made of cardboard or wood, and should not be allowed to fill up with waste paper before being emptied. Combustible decorations should not be used in a computer room. In general, only combustibles needed for computer operations (e.g. printer paper, cleaning agents, etc.) should be maintained in a computer room. Quantities of these materials for future use should be maintained in a storage room. Combustible fluids used in a computer room should be stored in enclosed metal cabinets when not being used. Kitchen appliances, and all other items that serve no useful purpose pertaining to data processing, are prohibited from the computer facility[no eating in the computer room gang! ed.] Floor panel lifters should be made available to computer facility personnel to help them investigate underfloor fire or smoke. When these devices are not being used, they should be maintained in access controlled rooms or locked up. DETECTION-ALARMS An approved early warning fire detection system should be in place throughout a computer facility and its associated offices and storage areas. This system should also be used for data center areas (not necessarily on raised floor) such as the COM Center,Print-Punch, Bursting,Bill Mailing, etc. (a) The system should function during a normal loss of power that is, it should be backed up by battery power or connected to an emergency power system for use during power failures. (b) The system should detect fire within the compartment as well as below raised floors and dropped ceilings. (c) The system should provide visual and audible alarms, or audible alarms only, within the computer facility. For any area of the computer facility not continuously monitored by computer facility personnel, the alarms for these areas should be connected to a station monitored around the clock. (d) There should be at least one audible fire alarm on each floor (e) The system alarm(s) should sound throughout the floor on which the detector(s) activate; and, in one case at a station monitored 24 hours per day, 7 days per week. (f) An enclosed area where an audible fire alarm cannot be heard when activated in an adjacent area, should be equipped with a seperate audible fire alarm. (g) Local municipal fire departments or local city code might require that the facility's fire alarm system should be connected to a fire department system. The local fire department should be contacted to determine if this is a requirement. In localities where this is not a requirement, computer facility management should have procedures in place to promptly notify the local fire department in the event of fire alarm activation at the facility. Smoke detection apparatus should be in air handling systems that serve the computer facility. Where computer equipment vendors provide automatic fire detectors in cabinets, these detectors should be interconnected with the computer equipment area fire detection system. Heat sensing devices are intended solely for the indication of control for the computer equipment cabinet components enviorment. These devices should not be connected to the fire detection system. Manual pull fire alarm stations should be readily accessible. The stations should be located at the normal paths of exit from a computer facility room or area. There should be at least one manual pull station on each floor with at least one station for each 10,000 square feet of area. A remote annunciator panel should be provided on each floor of the computer facility. This type of panel should be located in readily accessible areas such as elevator lobbies,corridors near elevators, or near a main stairwell in buildings without elevators. It is suggested that a Public Address (P.A.) system be installed throughout a computer facility. The system can be a beneficial supplement to a fire alarm system. The system should have emergency power. SUPPRESSION Halon or carbon dioxide (CO2) type fire extinguishers are recommended for electrical equipment areas. Halon or water type fire extinguishers are recommended to protect against fires in ordinary combustible materials such as paper. Personnel assigned to use Halon 1211 fire extinguishers to extinguish small fires that could occur in a computer facility should be instructed to discharge the agent no closer than six feet from the fire. One fire extinguisher should be provided for so many square feet of floorspace taking into account the maximum travel distance of 75 feet. Fire extinguishers should be located where they are easily seen and readily available. [no shit! ed.] A magnetic media operations library, and an AMA tape library in a data center, should be protected by a Halon 1301 flooding system or sprinkler system. Water sprinklers or Halon 1301 flooding systems, if used in computer facility rooms or areas where equipment operates at times without supervision, should have an adequate time delay feature built in and used (e.g. melt down of solder link or chemical pellet in sprinkler head; cross-zoned smoke detector system tied into flooding system) so the system will not dump immediately, enabling the detection system to alert appropriate personnel. This will provide personnel with the oppurtunity to reach the emergency area to either deactivate the sprinkler or Halon system (if a false alarm has occurred) or deactivate computer equipment. Carbon dioxide (CO2) flooding systems are not to be used in a computer facility. ACCESS-EGRESS Computer rooms should have the proper number of fire exits for egress purposes . All computer facility doors used for exit from rooms of the facility should be marked with a sign reading "EXIT" and the doors should open in the direction of exit travel. Exit signs should have green letters on a white field, except where otherwise required by law or ordinance. Each sign should be illuminated and such illumination should be continuous as required for exit ways. Computer facility doors not used for exit from rooms of the facility, which could be mistaken for an exit, should be marked "NOT AN EXIT" or by sign indicating their actual character. Well thats about it, the rest of stuff would be too boring to type in , Hell it was already getting boring.. but look for Part II to this file next issue ... it will be on ACCESS CONTROLS I promise it will be a hell of a lot more interesting than this first part. Network Operator +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CON Issue 1 Article 6 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% [] U.S.O.C. [] []***************************************************[] [] [] [] (Uniform Service Order Codes) [] [] [] []%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% Exactly what are USOC codes? USOC codes are alphanumeric id's that Bell uses to identify all types of services and equipment. Not to be confused with CLEI (Common Language Equipment Identifiction) USOC is more or less a helpful guide to recognizing hundreds of services of different types and equipemnt as well. It is used by all departments in Bell but some departments have specific uses for it.. But before I go into detail about the USOC codes and their format, I would like to explain how they were formed and why. The need for standard codes to be used for telephone service brought about the development of Uniform Service Order Codes (USOC). These codes were established for use by all associated companies in the Bell System. They provide a common language for the interchange of orders and information between long distance carriers and exchange companies. They were also designed for use in computer operations. As I stated before all departments use USOC codes. The Business Service Center/Residence Service Center and Marketing personnel use them to describe service items on the service order. The Installation and Maintenance/Installation and Repair forces use them for identification of equipment which they are to order and install. They also use them for changes made on the service order and for various reports. The Information Systems organizations use them for billing, summarization and the preparation of various reports. Usually, the Other Charges and Credit Statment that appear on your bill will carry these codes. While the other departments are not as dependant on USOC's, it benefits them greatly as it makes it easier to identify services and equipment. The USOC does not only identify service and equipment, but the proper rate for each code is listed as well for purposes of computer billing. FORMAT =============================================================================== Each USOC code is made up of 3 or 5 characters, each of which may be either a letter or a number. To avoid confusion and errors, the numerals 1 and 0 are not used and the letters O and I are not used. Three other characters which are used in the codes may be mistaken for each other. They are numberal 2 and the letter Z, the numeral 5 and the letter S, and the numeral 8 and the letter B. Special attention should be given to the writing of these characters so that errors will be avoided. A 2-character suffix is provided for some USOC codes. Suffixes and their use will be covered later. The general rule is that where recurring monthly charges are different, a seperate USOC must be assigned. Ther are some exceptions to this rule: 1. Those items whose rates are governed by the class of service (extensions or PBX stations, etc.) or those which are governed by the exchange in which they are billed (trunks or class of service, etc.) 2. Those items where a minimum rate or reduced rate applies according to the amount of service provided, such as channels,mileage, or centrex services. For example in the case of some mileage where one rate applies for the first mileage measurement and a different rate applies for the the additional mileage measurement. The mileage measurements are grouped in one entry as: 3 1L3AR SUFFIXES =============================================================================== A 2-character suffix is provided with USOC's to indicate additional information about the service or to provide variations in the basic items. In many cases suffixes are necessary to show the type and finish of the equipment which is to be ordered and installed. A 3-character USOC may or may not require a suffix to indicate color or style of a piece of equipment. A single suffix character is never used. Where only one suffix character is applicable, the character X is used for the second suffix. USOC's for channels,circuits and mileage consist of regular 3 character codes followed by 2 character suffixes. Codes for mileage are established as follows: The firs 2 characters of the mileage are always 1L. This is an indication that the code is for mileage or for a channel or circuit. The third character indicates the general category of the channel insofar as usage is concerned. For example the third character P is for full period telephone service and the third character Y is for private line teletypewriter service etc. The first suffix indicates further detail as to the class or grade of service, such as trunk, voice grade, 75-speed, duplex, etc. The second suffix can be dual in purpose, indicating both the basic category of length, such as continuous property, different premises, interexchange, etc. and specific length of the billing units involved, such as 1/10 mile, 1/25 mile and 1 mile etc.. DECODE MANUAL =============================================================================== If you are lucky enough to find a USOC manual, one of the pages might look something like this: USOC Description PIC SFF1 SFF1 CSQ COF OSP TAX ====== ============================== === ==== ==== === === === === ANUNW AT&T-C- WATS Answer supervision N 0 N N N BBAAS PL- Telpak A-Class of service N 1 N Y N The first column is the USOC. The USOC can be a 3 or 5 character code. A 3 character code followed by one suffix indicator +, e.g. 3CM+, indicates CRIS will accept with or without suffixes. A code followed by two suffix indicators ++ indicates suffixes are always required, e.g. PRN++ Next column is the word code description of the item or service. Next is the Predsignated Interexchange Carrier column. Y indicates an entry is necessary, N indicates an entry is not necessary. D indicates default. The next 2 columns are SFF1 and SFF2 which designate the suffix chart references. The next column is CSQ for class-of-service- qualifier A "1" indicates class of service and "0" indicates not a class of service. The next two columns are the Central Office Facility (COF) and Outside Plant Facility (OSP) indicators. A "Y" in these columns indicates that Central Office and/or Outside Plant work is required with the USOC. An "N" indicates no Central Office and/or Outside Plant Facilities are required. Next is the tax column. T-indicates the item is taxable. D-indicates tax depends on the class of service and N- indicates the item is nontaxable. There was one other column but It would not fit on the screen, its just a reference number column so that you can match up codes in the Encode manual where you can cross-reference items. There is one thing about the reference number section that is important.. the first character of the reference number identifies what type of service that USOC is associated with.. they are as follows: -E -Exchange Services -P -Private Line Services -A -Access Services -O -Official Company Services -R -Radio Common Carrier -C -Public Services (COIN) I Should point out that the usefulness of this file can vary depending on what you are working with. In COSMOS,LMOS etc. you will find USOC descriptions on the printouts or terminals which can be very helpful. By knowing your USOC codes, you can determine the type of line being worked on, what service they have, and what type of equipment. Now thats a lot of useful info for just one service order. These might be handy in bullshitting Business Office Reps or any other branch of the Phone Co. And of course they will appear on your actual phone bill usually on the Other Charges and Credit page. So have fun and I hope this has helped you to understand more about how the phone company works within their offices.

There are 80+ PDN's(Public Data Networks) worldwide. Many of these networks are accessible to hackers but un- fortunately, they also require an NUI(Network User Identifier) to use them at all. I will list some few choice nets that I think are good to mess with. Also, I will tell the exact format for logging into the network with an NUI. Although most of this information was obtained from tymnet, I feel this file will help others who dont know about "information" on tymnet or who are too lazy to look it up themselves. Some Terms to know before reading further. So that you understand how to access these networks, the following terms must be explained so your attempts at accessing these nets will be an easy and positive experience. DNIC-Data Network Identification Code The DNIC is what seperates one network from another. It is assigned by the CCITT(International Telephone & Telegraph Consultative Committee) to specify a particular Public Packet-Switched Data Network. The DNIC is made up of four digits. the way it is broken down is shown below. 3110 The first digit of the DNIC specifies the world geographic zone or network type. a list of the different zones and network types are shown below. 1st DNIC Digit Zone 0 Reserved 1 Reserved 2 Europe 3 North America 4 Asia 5 Oceania and Southeast Asia 6 Africa 7 South America 8 Telex/TWX networks 9 Telephone Networks The first digit of the DNIC + the next 2 digits make up what is commonly referred to as the DCC(Data Country Code). Some examples of DCC's are show below. DCC Country 208 France 234 United Kingdom and Northern Ireland 250 Soviet Union 302 Canada 311 United States 425 Israel 440 Japan 450 Korea 454 Hong Kong 502 Malaysia 505 Australia 602 Egypt 604 Morocco 724 Brazil 730 Chile The last digit of the DNIC specifically identifies the particular Packet-Switched Network. However, since there are more than 10 Public Data Networks in the US, the CCITT has granted the United States the use of the last 2 digits to identify the network. Some examples of DNIC's are shown below. DNIC Public Data Network 3104 MCI 3106 Tymnet 3110 Telenet 3126 ADP-Autonet 3132 Compuserve 3136 GEIS-Marknet 3137 Infonet 3140 SNET-ConnNet 3142 Bell South-Pulselink 3144 Nynex-Infopath 3149 Wangpac NUI-Network User Identifier or Identification Im sure many of you have used a Tymnet NUI like microwire or cmbpac. An NUI is used by the network to identify a user at logon. It is also used for billing purposes,security, and network management. So if you used microwire to connect to QSD,LUTZ, or Pegasus, microwire is billed for that connection IE. the Company has to pay for it. simple enough.. just remember that most NUI's are monitored. So it is important to not let any information which you do not wish to be disclosed pass through the NUI. Please refer to Doctor Dissector's Intro To PSN's or Erik Bloodaxe's Scan of Telenet in LOD Tech Journal #4 for explanation of X.121 International Addressing for NUAS. The list that follows are some overseas PDN's that probably many of you have seen people from on any of the European Chats. Please Note:All Networks,Phone numbers,DNIC's and login procedures have been checked to the best of my ability and are correct. ============================================================================== Network:Datex-P Location:Germany DNIC:2624 After Connection type . The network will prompt: DATEX-P:XX-XXXX (where XX and XXXX are the location and port number.) At this point you can enter in an NUI for Datex-P. NUI entry follows this format: type NUI EX. NUI dasboot Then it will prompt:DATEX-P;Password: of course you enter the password if there is one. if you get the ; prompt after you try an NUI, then it has no password. after you enter password, then you will be prompted to enter the X.121 International Address or NUA. EX.0208057040540 0 and 1 are the reserved zones in the DNIC table. they serve as specifying international access. EX. if you were trying to access QSD from Telenet, you couldnt type 208057040540 because it would think you wanted a host in the 208 area code of the US. thats why you have to type 0208057040540 to let the network know you want a host in France. Please remember that Telenet does not allow you to just call France. Once again you will need an NUI to do that. Also remember that you will need someway to call overseas using a PBX or Network Gateway to use these overseas PDN's. The rest of the networks I list will be shorter and just follow the format I explained above.

Network Operator +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ CON Issue 1 Article 8 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ NEWS AND CURRENT EVENTS ======================= Network Challenge: Prepare for 800 database =========================================== SWBT and other Bell operating companies are now in the middle of a huge job: to implement 800 database service. An FCC order requires the service to be operational on March 1,1993. To meet that deadline, SWBT network operations personnel have been working feverishly to complete installation and testing of common channel signaling (CCS). The implementation will be welcomed by the thousands of companies that use 800 numbers, according to Dan Winters, 800 database product manager. "National 800 database service will revolutionize how the toll-free industry operates," Winters said. "The most significant change from today's 800 service is that 800 numbers will no longer be tied to specific interexchange carriers. Subscribers of 800 services will be able to vary their interechange carrier while keeping the same 800 number." An 800 number that spells out a word or phrase can be an important marketing tool for the subscriber. And the flexibility to change interexchange carriers means the subscribers can choose the carrier that best meets its needs. The FCC order includes "call setup thresholds" (translation: the maximum allowable time that occurs between the completion of dialing and the first ring). Meeting those thresholds will require extensive modifcations to SWBT's network, including the use of new CCS technology. One modification requires routing 800 calls from central offices that aren't equipped to access the new database to a tandem office that is equipped. Another effort involves establishing and testing the 800 database itself. Neither is an easy task, said Mike Grogan, area manager-common channel signaling. "Testing compatibility between our switches and carrier customer switches and establishing seperate signaling circuits for CCS to those customers is a big job," said Grogan. "SWBT has taken these actions to meet the FCC requirements but they will also help modernize our own capabilties. "Meeting both the FCC deadline and SWBT's own aggressive 800 implementation schedule will require a significant installation, coordination and testing effort." Switches GO Digital! ==================== SWBT is now 2 years into the Telefuture 2000 network modernization plan,82 electromechanical switches in Missouri have been replaced with digital switches. Digital switching has meant improved service for more than 158,000 customers in Missouri, giving them access to touch-tone dialing and Custom Calling Services. In addition to the digital switching equipment, SWBT will install more than 800 miles of fiber optic cable and T-carrier statewide to provide clearer transmission on long distance calls in rural areas. Also as part of the $180 million network modernization program, SWBT plans to phase-out nearly 60,000 party lines by December 1997. About 14,000 party lines in Missouri have now been converted. "The party line elimination program is right on schedule," said Ed Wheatley, area manager-budgets. Texas and Kansas have similar network modernization programs under way. As part of the Texas First plan, Texas will convert 196 central offices to digital and eliminate nearly 104,000 party lines. N-carrier replacement is not part of the Texas plan. The Lone Star state expects to complete its modernization effort by November 1994. Kansas also is meeting its timeframes for updating its telecommunications technology outstate. The TeleKansas plan calls for replacing nearly 1,100 miles of N-carrier with digital facilities, converting 131 central offices to digital switching and upgrading more than 31,000 party lines by year-end 1994. SWBT opens new ISDN market ========================== SWBT recently began selling SmartTrunk service in Kansas. The service is based on primary rate interface ISDN technology. SmartTrunk is a large-capacity type of ISDN service. It has high-volume, 23-connection channels between SWBT's telecommunications network and the customer's PBX. "SmartTrunk gives our customers flexible control over their trunking networks," said Mike Reddout,area manager-product management. "In a nutshell, SmartTrunk is fully digital networking which lets customers communicate with more speed,quality, economy,control, value and ease. "Typical customers for SmartTrunk service are telemarketing companies, service bureaus, catalog businesses and other firms with heavy,but flunctuating,calling volumes from their PBX's." SmartTrunk service offers customers an automatic call-back feature and dynamic channel allocation (which manages distribution of calling paths). The service provides customers efficiencies and expandability to provide for a business growth. SmartTrunk service in Texas and Missouri. The company plans to present tariffs to the public service commissions in Arkansas and Oklahoma in the next few months.
