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 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.
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 then configure Port 2
to only accept calls from that unique Source ID (7).
QUAD BRI/U MODULE: USER TERMINATION
While interfacing to user equipment (terminal adapters), the ATLAS 550 acts
like the network. When you are working in the
U SER T ERM section of the
D IAL P LAN menu and S LT is defined as U-BRI-4 , the following interface con-
figuration options are available:
S WITCH T YPE Write security: 3; Read security: 5
Defines the type of ISDN switch that the port simulates. If connected to
another ATLAS, both need to be set to the same type. Choices include
L UCENT 5E , N ORTHERN DMS 100 , and N ATIONAL -ISDN .
S PID L IST Write security: 3; Read security: 5
The port, acting as the network, must use a SPID and a phone number in
order to satisfy the ISDN connection protocol expected by the user’s Termi-
nal Adapter (TA).
P HONE N UMBER The phone number(s) assigned to this BRI phone line.
SPID N UMBER Defines the SPID number(s) used for this BRI line. Although the value of the
SPID is not significant, a SPID must be entered for each phone number. For
convenience, the SPID can be set to be the same as the phone number.
C ALLS For user terminations, the number of calls is fixed at 2 .
The ATLAS 550 does not support autoSPID detection software which
some terminal adapters offer.
