Write security: 3; Read security: 5
Determines how the ATLAS 550 switchboard uses B channels for call routing. The Circular method can be
used for call load balancing among the available B channels on this interface.
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.
DIAL PLAN (U-BRI) > NETWORK TERM
Write security: 3; Read security: 5
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
Write security: 3; Read security: 5
Specifies the configuration parameters for the endpoint.
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:
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.
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.
• Lucent 5E • Northern DMS 100 • National ISDN
PHONE NUMBER
