DIAL PLAN (FXO) > USER TERM > IFCE CONFIG > DIRECT INWARD DIALING
Write security: 3; Read security: 5
Defines to the ATLAS 550 whether Direct Inward Dialing (DID) is being used by the network. DID is
ENABLED when configuring the FXO Module for USER TERM operation and the following information must
be defined:
DIAL PLAN (FXO) > USER TERM > IFCE CONFIG > DID DIGITS TRANSFERRED
Write security: 3; Read security: 5
Defines the number of digits sent to ATLAS 550 from the network if DID is used. This option only displays
if DID is set to ENABLED.
DIAL PLAN (FXO) > USER TERM > IFCE CONFIG > 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.
DIAL PLAN (FXO) > USER TERM > IFCE CONFIG > SOURCE ID
Write security: 3; Read security: 5
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. 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 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
then configure Port 2 to only accept calls from that unique SOURCE ID (7).
DIAL PLAN (FXO) > NETWORK TERM > IFCE CONFIG > PORT SELECTION
Write security: 3; Read security: 5
Determines how the ATLAS 550 switchboard uses FXO ports for call routing. The CIRCULAR method can
be used for call load balancing among the available ports on the module.
STRIP MSD does not affect Call Accept criteria. All of the digits (including the MSDs that
are subsequently stripped) are used as accept criterion.
NORMAL Always start with the lowest numbered available port (i.e., for a Quad FXO
Module with four configured interfaces, Port 1 would always be used first if
available).
