| \\===============================// | |
| 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. | |

| have phun & read Phrack... Feel free to contact me: | |
| mrnobody@pil.net | |

| - 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) | |
