NORMAL	Always start with the last channel configured (i.e., for a full PRI channel
	23 would be used if available).
CIRCULAR	Contiguous channels from last to first.

DIAL PLAN (BRI DBU NETWORK INTERFACE AND QUAD BRI/U MODULES)

All menu items in this section (listed as U-BRI) apply to BRI DBU Network and Quad BRI/U Module interfaces configured in the DIAL PLAN.

This menu allows the user to define option parameters for ports which terminate a BRI connection from the network.

DIAL PLAN (U-BRI) > NETWORK TERM > IFCE CONFIG

DIAL PLAN (U-BRI) > NETWORK TERM > IFCE CONFIG > SWITCH TYPE

Write security: 3; Read security: 5

Defines the type of BRI switch to which the port is connected. If connected to another ATLAS 550, both need to be set to the same switch type. The following options are available:

• Lucent 5E • Northern DMS 100 • National ISDN

DIAL PLAN (U-BRI) > NETWORK TERM > IFCE CONFIG > SPID LIST

Write security: 3; Read security: 5

To properly operate with a network ISDN switch, the BRI interface must have Service Profile Identifiers (SPIDs) and phone number(s) that match the SPID(s) and phone number(s) programmed into the ISDN switch for this line. Each BRI may have one or more phone numbers and SPIDs. The SPID LIST submenu defines these parameters to ATLAS.
