-
- 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!

- 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!

- 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.

- 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)

-
- 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.

- 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.

- 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.

- [] 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.

- %===============================================%
-
- This file is for anyone who is interested in any of the European Networks
- or networks other than the ones in the USA. 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 .<cr> 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 <nui><cr> 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 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.
