Section 4, User Interface Guide ATLAS 550 System Manual

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.

STRIP MSD does not affect Call Accept criteria. All of the digits (including the MSDs that are subsequently stripped) are used as accept criterion.

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.

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).
