digital network. The MPPD contains a master and a secondary clock, which are
synchronized with the frequency of an incoming T-1 span. The module also
contains its own clock for use when T-1 synchronization is not available or
lost.
The MPPD also generates the ringing tones, busy signals, and reorder
tones heard by the customer and sends the zip (alert) tone to the operator.
The CC controls the interaction between the PM components and the
DARU. It contains the Office Dependent Data Base (ODDB), which is a system
table that describes the configuration of the TTS. The CC uses the ODDB to
determine whether an incoming call is an ANI or ONI trunk.
The CC sets up paths through the digital network in order to
coordinate the resources of the CAIS/LAIS. It receives messages from the
PMAC, stores information necessary for returning a response to the appropriate
trunk, and controls message routing to and from the ARC or the operator. It
also synchronizes the TTS and the Directory Assistance System (DAS) for
operator-caller communications.
The CC is a Power-series standalone processor that contains a central
processing unit (CPU-2), based on the Motorola 68000 microprocessor. The
processor also contains distributed intelligence for controlling the memory
subsystem, the IO (input/output) subsystem, and the disk/tape subsystem. Each
CC includes a Winchester disk drive, a quarter-inch tape drive, and additional
miscellaneous hardware.
DAIS II Audio Response Unit (DARU)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The DARU contains the VOCAL boards that produce automated
announcements, which are compiled from a vocabulary stored in RAM. A
CAIS/LAIS contains 1 to 3 DARUs, each with 48 ports.
If a CAIS/LAIS houses more than one DARU, the units are multi-dropped
together. One DARU is always linked to the ARCs (either directly or by modems
and telephone lines) so that the announcement vocabulary can be downloaded
from the ARCs if necessary.

Much of the information in this file is copied verbatim from the
instructional booklet sent to me by CCI. Their documentation is extremely
in-depth and well written, and, with some looking over, is easy to
understand. Much of the information in here is confusing with all of the
acronyms used as well as technical terms, but if you cross-reference acronyms
throughout the file, you should be able to see what it stands for. Also, if
you don't understand what something does, just think of it in terms of use by
the telephone company in the context used and you can generally get an idea
of what it does or is used for. I hope you enjoyed this file and continue to
read Phrack Inc. files to learn more about the system we use and experience.
Any constructive suggestions are welcomed directly or indirectly.

Author Note:
Ugg! I looked at my first file after it was released and saw a lot of
misspellings, errors and other screw-ups and was completely embarrassed. I
did not have time to edit the file and I was also writing the second file
which dealt with gaining privileges. I threw these two files at Taran King
who in turn merged them together. So I humbly apologize for all of the
errors in the last file. In this file I will revise the old file and
continue with some more methods of gaining access and also list out some
very basic commands for beginners. As I said before, if you have any
questions you can reach me on any board I am currently inhabiting. Hope to
hear from you...
*** Gaining Access From Scratch ***
I made a mistake in my last file and stated that FAM was not a default. FAM
is a default, but it can be taken out by the system administrators.
To get a listing of every possible account on a system, it is really quite
easy. They are located in the MFD directories. Type:
A MFD <MFD #> (Without the "<" and ">" signs)
Or just:
A MFD
Then type LD and hit return. Now, you will see a listing of files and
underneath should be a listing of directories appropriately named
Directories. These directories are valid User IDs. However, I believe that
directories that have an "*" character in them cannot be logged in to.
