These options reflect the network provisions for this SPID. If the BRI was
purchased with different services provisioned for the SPIDs, then the call
must match the services supported.
S TRIP MSD Write security: 3; Read security: 5
Strips a selected quantity (choose from
N ONE , 1 , 2 , and 3 ) of the Most Signif-
icant Digits (MSD) of a dialed number prior to being forwarded out of the
port.
E XAMPLE :
A network port could be set to accept all calls beginning with 9 (9$), and
then with
S TRIP MSD set to 1 , all digits would be sent toward the network
except the leading 9.
S OURCE ID Write security: 3; Read security: 5
Simplifies the creation of a
D IAL P LAN in applications where the criterion for
switching calls to a certain endpoint is a function of which endpoint origi-
nated the call.
• Default value = 0. The default ID for all endpoints is 0 and for all accept
numbers is 0. With default values, all calls are routed based only on the
dialed number.
• Multiple endpoints can have the same S OURCE ID .
• When creating the C ALL A CCEPT list, specify a S OURCE ID (s) as well as a
dialed number or range of dialed numbers to accept.
E XAMPLE :
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 then configure Port 2
to only accept calls from that unique Source ID (7).
CREATING DIAL PLANS—EXAMPLES
The ATLAS 550 D IAL P LAN acts as the numbering plan for switched connec-
tions. This menu defines to the ATLAS 550 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, the ATLAS
550 must be able to terminate network connections (Network terminations)
and emulate the network onto other termination equipment (User termina-
tions).
S TRIP MSD does not affect C ALL A CCEPT criteria. All of the digits
(including the MSDs that are subsequently stripped) are used as
accept criterion.
