must define the trunk number.

When the network connection does not provide DID digits, the ATLAS 550 must be given a number to use
to determine which user endpoint should receive the incoming call. TRUNK NUMBER displays only when
DID is set to DISABLED.
Example: To connect an incoming DS0 (trunk) to an endpoint with the accept number of 963-8615, set the
trunk number to 963-8615.
DIAL PLAN (T1/PRI) > NETWORK TERM (RBS) > IFCE CONFIG (RBS) > STRIP MSD
Write security: 3; Read security: 5
Strips a selected quantity (choose from NONE, 1, 2, and 3) of the most significant digits (MSD) of a dialed
number prior to being forwarded out of the port.
Example: A network port could be set to accept all calls beginning with 9 (9$), and then with STRIP MSD
set to 1, all digits would be sent toward the network except the leading 9.

Simplifies the creation of a DIAL PLAN in applications where the criterion for switching calls to a certain
endpoint is a function of which endpoint originated the call.
DEFAULT VALUE = 0. Zero is the default ID for all endpoints and all accept numbers. With default
values, all calls are routed based only on the dialed number.
Multiple endpoints can have the same SOURCE ID.
When creating the CALL ACCEPT list, specify a SOURCE ID(s) as well as a dialed number or range of
dialed numbers to accept.
Example: An application requires that all calls that originate from Port 1 of the ATLAS 550 in Slot 1 be
switched to Port 2 of that same module. Assign a unique SOURCE ID (e.g., 7) to Port 1 of the module, and
If Feature Group D is used, DID only refers to DNIS digits.
The trunk number must be specific (i.e., no wildcards).
STRIP MSD does not affect CALL ACCEPT criteria. All of the digits (including the MSDs that
are subsequently stripped) are used as accept criterion.
