Basic Rate Module (BRM-S)

IMPORTANT
Each Basic Rate Module (BRM-S) provides two BRI S/T-interface ports for connecting BRI
trunks to the system. The BRM-S does not support video conferencing or connection of BRI
endpoints to the system.
Each ISDN BRI port provides two trunks/circuits/bearer-channels for a total of four BRI trunks
possible on each BRM-S module in the chassis.

Toll Restriction

The following features provide toll restriction on the system and are described in further detail
in this section.

installations.
Trunk Group Toll Restriction: Each trunk group can be designated as "subject to toll
restriction" or "not subject to toll restriction" in Database Programming. If subject to
toll restriction, endpoint class of service is checked when the trunk group is selected for
placing an outgoing call. The exceptions to trunk group toll restriction are as follows:
— Emergency Call Feature: When the Emergency Call feature code is entered, the
designated trunk access code is used to seize a trunk and the programmed emer-
gency number is dialed regardless of any endpoint or trunk group toll restrictions.
— Automatic Route Selection (ARS): Calls placed using ARS (except Emergency
Call feature calls) are always subject to toll restriction, regardless of the selected
trunk group's toll restriction programming. Note that only the endpoint COS is
checked; the trunk group COS is not.
— Network ARS Calls: When determining toll restriction for an ARS outgoing call,
the network checks the endpoint toll restriction based on the database information
on the node on which the endpoint resides, not the node that contains the trunk
which the system uses to place the call. The system does not check the trunk COS
for ARS calls.

ARS does the following:
•
Checks the number and
finds dialing pattern 602+
in Route Group 2.
•
Selects a facility group
with an available trunk.
•
Checks toll restriction and
outgoing access.
•
Uses dial rules to modify
the number:
Echo 3 Digits After Toll
Echo Local Address
Add Account Code
•
Dials the modified num-
ber.
