Northern Telecom SL-1
by ICEMAN
This article is fairly lengthy, but I felt that it was worth including all the information that I did, even though a great deal of it is useless to someone attempting to take advantage of such a system. If you have any interest in learning about PBX's, then in my opinion it's worth reading in it's entirety. Just a note that you can't expect to learn this all in one sitting, it takes time and experience. I would say that about 50% of this material was taken from other sources, ranging from Northern Telecom manuals, to classroom handouts used to educate those who work with them. Although most of the technical information is straight out of the book, I did my best to simplify it as much as I could, so that the reader can get a better grasp on it.
Development of Northern Electric's SL-1 started in 1971. Their objective was to design a superior communications system for business subscribers in the range of 100 to 7600 stations. The system had to encompass all the features of a PBX, Centrex and key systems and be economically competitive with them. It had to have new custom services not previously feasible with the older systems. It had to be easy to learn and to operate. As well, it had to be easy to install and maintain.
What the designers came up with was a digital, stored program control machine using an 8-bit PCM. They also came up with a new telephone instrument, the SL-1 telephone, which is a multi-line instrument with many features, but uses only 2 pairs of wires, instead of 25 pairs required by key telephones.
The SL-1 system has three main parts: The common equipment (CE), the peripheral equipment (PE) and the power supplies.
The CE performs the central control and switching functions for all the connecting lines and trunks. It has a central processing unit (CPU) and read/write memory which stores all the operating programs and data unique to the particular system, including switching sequences, feature and class of service information, and numbers and types of terminals. It also has a magnetic tape unit for high-speed loading of the operating programs and data into the R/W memory, providing data restoral after a power failure. The tape also contains the diagnostic routines. There is a Teletype to communicate to the system with and to print error messages on. The network circuits perform the switching duties for all lines and trunks. The digital service circuits provide for such functions as dial and ringing tones and call conferencing.
The CE units communicate over a common central bus under control of the CPU. Speech signals, converted to digital, follow a separate path on a network switching bus.
The PE performs the interface between the line and trunk circuits and the SL-1 system. It consists mainly of line and trunk cards which convert analog speech to digital signals for digital switching and vice versa. Lines connect to individual instruments and trunks to other PBX's. Peripheral buffers act as interface between the PE and the CE providing power control, timing and switching control signals for the line and trunk circuits. Digital conversion into 8-bit PCM is done by a single encoder/decoder (codec) for each line or trunk. This codec is a custom LSI circuit.
Between the PE and the CE, all signals travel in digital format on time multiplexed loops. Each loops carriers 30 voice channels, one control signalling channel and one unused channel. The channels operate at 64 kbps to give a total data rate of 2.048 mbps. Each loops terminates on a different circuit pack in the CE. There can be up to 16 multiplex loops.
When a call is set up, the CPU assigns each party a channel from among the 30 on their own multiplex loops. These channels form a matched pair. For instance, the calling party may use channel 2 of it's digital loop, and the called party may use channel 3 of it's loop.
The SL-1 conducts audio digitally. The line and trunk cards contain A/D and D/A converters. Received audio is changed to a digital signal and put on a voice channel. At it's destination, the digital signal is converted back to analog audio.
All programming is done from a keyboard with the output going to a printer. To program, a specific diagnostic is selected, and is automatically loaded from tape. Once this is done, the appropriate commands are entered to change the options. All typing is echoed on the printer and the SL-1's responses are printed out. If any system parameters or configurations are changed, these changes will not survive a total power outage unless a new tape is made.
In case of a power outage, upon restoral of power, the SL-1 activates the tape unit and loads in the system operating data, and runs some diagnostics. This takes from 5-15 minutes, and at the end of that time, service is fully restored with all the options which were recorded on the tape being implemented. Of course any user-selected options like speed call lists and call waiting which had been selected before the outage will be lost.
Automatic diagnostics (called 'background' programs) are being run constantly with the results of any problems being printed out. At midnight a more thorough set of diagnostics are run. Any of the diagnostics may be run on demand from the keyboard. Also available on demand from the keyboard are a series of diagnostics to determine the status of lines and trunks, to trace calls, and to print lists and traffic studies.

Station to station calling - Any station can directly call any other station without attendant assistance.
Direct Outward Dialing (DOD) - Allows a station to gain access to the exchange network without attendant assistance and receives a second dialtone.
Hunting - Routes a call to an idle station directory number when the called number is busy. The numbers in the hunt group do not have to be in sequence nor do they have to appear on the same instrument. The sequence can be consecutive (station directory numbers are hunted in ascending numerical order) or non-consecutive.
Access to paging - Provides a connection to customer-owned paging equipment.
Access to Automatic Recorded Answering Equipment - SL-1 stations can have incoming messages recorded on customer-provided answering equipment by forwarding calls to the directory number (DN) assigned to the equipment.
Direct Inward Dialing (DID) - Allows an incoming call from the exchange network to reach a station without attendant assistance. The DN for each station will normally be the last 2,3 or 4 digits of the 7 digit exchange network number.
Tandem Switching - The SL-1 can act as an intermediate switching point for traffic between other PBX's.
Manual Service - Does not provide a dialtone when a station goes off-hook. Instead the attendant is alerted and completes the call for the user.
Private Line Service - Permits the appearance of a private central office line on an SL-1 Telephone set. Dialtone is received directly from the telco and calls are not processed by the SL-1.
Multi-Customer Group Operation - Allows for the provision of services for more than one business customer from the same switching machine. Each customer is totally separate from the others, may have the same directory numbers as the others, has his own attendant console, his own trunks, and cannot directly call stations belonging to the other customers.
Service Restrictions - Allows the ability to restrict various functions.
Intercept - Disposes of calls which cannot be completed because of restrictions or dialing errors. They are either routed to the attendant or overflow tone.
Special Dial Tone - A Regular dialtone with three 128 ms interruptions at the beginning to advise the user that his hookswitch flash has been successful.
Line Lockout - Disconnects stations which have been off-hook for too long to prevent system problems.
Night Service - Allows the attendant to preconnect some or all of the incoming telco trunks to selected DN's on the SL-1.
Emergency Transfer - Puts the system in the power fail transfer mode. This transfers telco trunks to selected stations to provide some continuity of service to the outside world during the time the SL-1 is inoperative.
Remote Administration and Maintenance - Permits operation of the diagnostics from a remote location via a modem and telephone line. You may do anything from the remote terminal that you can do from the local terminal.
Call Forward - Busy - Routes incoming calls to another number when the called station is busy.
Call Forward - Don't answer - Routes incoming calls to another number when the called station doesn't answer within a prescribed time.
Call Forward - Follow me - Routes incoming calls to another, programmable number.
Call Waiting - Informs the user of a second incoming call while he is already in conversation. He can then place the first caller on hold and answer the second call. He can then return to the first call.
Conference - Allows a user to connect up to either 1 or 4 additional persons into an existing call. Up to 2 of the users may be trunks.
Call Pickup - Allows a station to answer an incoming call to another station in the same pickup group by dialing a special code.
Ring Again - Permits a calling station, on encountering a busy DN, to operate a dedicated key or dial a special code to have the system monitor the called station and alert him when it goes idle. He is then automatically connect to that station when he goes off-hook or presses the key during the alert and the system rings that station.
Data Transmission - The SL-1 is suitable for voiceband data transmissions and is compatible with a conventional modem.

'Generic' refers to the software version. It is expressed as a 3 or 4 digit number where the first part of the number indicates the machine it is for and the second part indicates the purpose of the software and serves as a version number and also indicates the type of machine it can be used with. The 'X' stands for a 1 or 2 digit number representing the model:
1 = SL1-L 2 = SL1-VL 3 = SL1-LE 4 = SL1-VLE 5 = SL1-A
6 = SL1-XL 7 = SL1-M/S 8 = SL1-N 9 = SL1-XN 10= SL1-ST
11= SL1-NT 12= SL1-XTMaintenance Programs
All troubleshooting procedures, configuration changes and circuit disabling/enabling are carried out from the keyboard of a Teletype via software programs. There is virtually no physical contact with the exchange other than required to remove a defective board and replace it with a spare.
Even this does not require tools.
This material will give only a brief description of each program and some examples of how to use them.
Before running a program you must first gain access to the computer. The dialup will normally be a 1200 baud connection, with an even parity, databits of 7, and stopbits of 1 (E71). Once connected press the 'return' key to wake the system up. The system SHOULD respond with 'OVL111 BKGD' or 'OVL111 IDLE' and now you know it's alright to login. If the response is 'OVL000' and then a '>' prompt you are already logged in, and you can go straight to loading an overlay.
Type 'LOGI' to initiate the login. Make sure when entering commands that they are all input in uppercase. The system responds with 'PASS?'. Now enter the password. The default password is '0000' but is obviously configurable. If you have correctly logged in, the system will respond with a '>' prompt. The system will display this prompt whenever waiting for operator input and is not running a diagnostic program. Once a diagnostic program is running the prompt becomes a '.' (period). If you are not logged in, there is no prompt.
What follows is an example of what you will see during login.

Now after gaining this information, we can determine what type of system we're dealing with. Notice that the version number is 1011. Now refer back to the listing of SL-1 Models for the information we seek. We are logged into an x11 system (last 2 digits of the version number). Unfortunately, there are two system with x11 generics, and none of which have a release number of 14, so we're either dealing with an SL1-M or an SL1-S, with either a 60-400 or 30-160 line capability respectively. Although this information isn't extremely useful, it comes in handy when determining how large the system is.
Overlay Programs
Upon first logging in, no program is loaded, and you must load a program (overlay) into system memory. This is done by the command 'LD' followed by a space and the overlay number. To load overlay 10 you would simply do a 'LD 10'. It will take approximately 1 minute to load the overlay into memory from tape, if the system uses a tape drive. If the system uses other methods of storage (disks, ROM) then it will load quickly. Once the program is loaded, a 'REQ' (request) prompt will appear. The system is now waiting for input from the user.
There are many different overlays which can be used, all of which are explained in the following section.

ServiceProgramming
The following few sections will summarize the possible commands and responses for various overlays. Since there are various models of SL-1's as well as various software versions running on them, there are bound to be differences in the commands, to accommodate this, notice the 'generic' heading. If 'all' appears under this heading, then the following command/prompt is found in all models/versions, otherwise it only appears in the models/versions that are specified under this column. Once an overlay is loaded, the first prompt will appear. For example when overlay 10 is loaded, the 'REQ' prompt will appear, and you will choose the appropriate response, in this case the choices are 'NEW','CHG','MOV','OUT', and 'END', then the next prompt will appear and so on. Note that not all prompts will appear for all versions, but i've done my best to include possible prompts that you can come across. When entering input, if you make a mistake and would like the system to disregard the current line, end the line with a '*' then a carriage return. If you make a mistake, and would like to return to the beginning of the input routine, enter '**' at the end of the line, followed by a carriage return, and you will return to the 'REQ' (request) prompt.

Those are the main overlays used to modify setups and print the system configuration information. Now you may be asking, where do I find an SL-1? SL-1's are mainly used in buildings, ranging from department stores to large office complexes. The dialups are commonly found off of an extension of the PBX, I've come across several while scanning for VMB's, which are becoming more common in stores every day. I've never however come across one while exchange scanning, and I really don't think you would find many this way.
Anyways have fun, and remember, knowing is half the battle.
