»» Strip MSD
Write security: 3; Read security: 5
Strips a selected quantity of the Most Significant Digits (MSD) of a dialed
number for ATLAS prior to being forwarded out of the port. The choices are
None , 1 , 2 , or 3 . For example, if you set a Network port to accept all calls
beginning with 8 (8$) and then set Strip MSD to 1, all digits except the lead-
ing 8 will be sent toward the Network.

»» Source ID
Simplifies the creation of a Dial Plan in applications where the criteria for
switching calls to a certain end point is a function of which end point origi-
nated the call. Keep in mind the following:
• Default value = 0. The default ID for all end points is 0 and for all
Accept #
s is 0. With default values, all calls are routed based only on
the dialed number.
• Multiple end points can have the same Source ID .
• When creating the call accept list, specify a
Source ID
as well as a dialed
number or range of dialed numbers to accept.
Say, for example, that an application requires all calls originating from
Port 1 of the T1/PRI module in Slot 1 be switched to Port 4 of that same mod-
ule. You would assign a unique
Source ID
(e.g., 7) to Port 1 of the module,
and then configure Port 4 to only accept calls from that unique
Source ID
(7).
CREATING DIAL PLANS—EXAMPLES
The ATLAS
Dial Plan
acts as the numbering plan for switched connections.
This menu defines to ATLAS the phone numbers and features associated
with dual-tone-multifrequency (DTMF) dialing, Primary Rate ISDN (PRI),
and Basic Rate ISDN (BRI). To operate as a switch, ATLAS must be able to
terminate network connections (network terminations) and emulate the net-
work onto other termination equipment (user terminations).
DID Digits
Transferred
Write security: 3; Read security: 5
Defines the number of digits sent to ATLAS from the Net-
work.
DID Prefix Write security: 3; Read security: 5
Defines to ATLAS the prefix digits which are not received as
a part of the DID number. ATLAS uses the combination of
prefix and DID number to determine the User end point
that receives the incoming call.
The Strip MSD parameter does not affect the Call Accept criteria. All of
the digits (including the MSDs that are subsequently stripped) are used
as accept criteria.
