|| The DCO-CS Operating System ||

\\===============================//
OK... this is the first part of what (hopefully) will be a little
series type thing of articles on the DCO operating system, which is from
Siemens. DCO is run on an LLS/RLS-1000/RLS-4000 machine. It has
psychotically mad logging, but the logs are configurable from the admin
accounts. The DCO box I was using just happened to only have a 1200 bps
dialup, so some operations (i.e. listing INWATS trunks and what they route
to) were painfully slow considering the large amount of trunks this thing
can control. It is similar to a 4ESS in some ways, and offers some PABX
functions. A guy can have lots of fun with one of these things...
Some features/specifications:
Billing Computer Interface
--------------------------
"The DCO-CS collects AMA data and provides direct data interface with
your business computer, as well as 1600 BPI magnetic tape backup
or primary data collector"
International Callback
----------------------
"Allows the system to place a return call to an international
subscriber for the dialed domestic number originally called, either
through a live or automated operator position."
ISDN Transport
--------------
The DCO-CS is capable of switching 64 Kb/s data. This allows people
(customers, hehe) to switch Primary and Basic Rate ISDN traffic.
LEC Services
------------
Full LEC services are offered, including POTS (duh), Centrex &
Enhanced Centrex (combines ISDN & POTS lines in the same Centrex
groups, direct inward dialing, call forwarding, hold, call transfer,
intercom, conferencing, OUTWATS over line groups of any size.), CLASS
including calling number delivery and display, selective call blocking
and forwarding, automatic recall and call trace.
"Hacker intrusion is detected and 'thwarted' by sophisticated pattern
recognition software. The DCO-CS switch lets you detect abused authorization
codes and service-denied authorization codes and automatically route the
calls to your service departments. The system also offers timed threshold
levels for both ANI and authorization codes as another form of fraud
protection. It delivers detailed traffic and facilities usage reports to help
you plan the optimum use of your private and leased facilities."
--Siemens Stromberg-Carlson
Calls are processed simultaneously with separate processors and
switching matrices. In the event of a failure, not even calls in the process
of being switched are lost because when the failure occurs, the system simply
switches to "its redundant processor and memory".
I guess that before I dive straight into the commands, I should
discuss something pretty damn important. That something is MMI. MMI
stands for Man-Machine-Interface,and is basically the 'shell' for this
system. First off, in MMI, every command is prefixed by a '$', ie, to run
the account maintenance program, "passwm", one would type: "$PASSWM",
without the quotes. Always put a comma between parameters. For example,
say that a program ADDTFREE requires the parameters SAC(service access
code),Toll-Free Number, and the Trunk to Assign the Toll-Free number to.
The hypothetical command to add a tollfree number, 555-6969, with a SAC of
800, for example, and route it to (123)456-7890, would be:
"$ADDTFREE 800,5556969,1234567890"
(without the quotes). The ';' denotes a line terminator. For example, to run
a program PROG1, which,say, clears the terminal screen, and the INWANI
utility, one would type: "$PROG1;$INWANI", without the quotes. The ""
(quotes) are used to contain a string of one or more characters. A string
is considered anything that contains either a blank or comma not being
used as a delimiter. The '\' allows special characters to be input to
tasks (similar to linux/unix?). And finally, the ':' is synonymous to done
(whatever that means).
Some more on MMI... The command line/response length is 65 characters,
so anything longer than 65 will be truncated. Exit is a valid response at any
prompt. Help is also valid and lists the valid responses with descriptions.
To automatically display the help information prior to all prompts, type
"HELP=ON" without the quotes. "HELP=OFF" disables this function. The '^' is
used to back up a menu. Control-P cancels a function in progress. The '&'
represents logical AND. However, the '&&' represents a logical inclusive.
The '*' is a wildcard, and allows the user to select the entire range of
possibilities.
'Option Words'- the option word is entered on the command line
after the task(command) name. The Option Word can be either in octal or
ASCII.
Value ASCII Definition
-F1 /NODIAL no dialogue (header or trailer msg output) to terminal
-F2 /OFFLINE Request communication with offline CP
-F4 /NOCOMM No user input. All input must be on the command line
-F40 /NOPAGE Do not paginate output.
Values may be added together to indicate multiple options, eg:
-F3 = -F1 and -F2.
One final thing: I said that all commands must be prefixed with a '$',
however, this does not apply to input, ie when inside a program it is not
necessary.
The next part is basically just a command list for DCO. I will do
a more detailed (tutorial even) as i learn more and as people ask for one,
or if I just feel like writing it (and I probably do, as I have read Phrack
for some time and always wanted to contribute). One last warning: the LLS/RLS
is a fairly large system, so be VERY CAREFUL as one can do about as many
bad things as good things if you're not careful.

Thats all for the commands... I will probably write a follow-up
explaining some of the commands usage, what a DCO looks like when you call it
(ie how you know its a DCO machine), what some defaults are, how to route
numbers using INWATS or INWANI, and whatever else i figure out... for now,
have phun & read Phrack... Feel free to contact me:
mrnobody@pil.net
resources i used:
- an actual RLS machine running DCO siemens stromberg-carlson
- my mind
- the minds of my phriends, to whom i give much thanks:
c-stone (is thatit?), lefty, port9, cyklonik (hope everything turns out
OK....), a guy named don in CA :), and ben (look at me now, m0f0)
sorry if i forgot anything or anyone that helped me...
look out for "The DCO-CS part 2" soon...
