Configuring ISDN BRI network cards
Understanding the Net BRI parameters
This section provides some background information about the Net BRI parameters.
Assigning a profile name
You can configure several profiles and activate a profile when it is needed. Each profile’s name
should indicate its usage.
Carrier switch type and how it operates
Switch Type specifies the central network switch that provides ISDN service to the MultiVoice
Gateway. (For details about supported switch types, see the MAX Reference Guide.)
BRI Analog Encode
If you are going to receive modem calls, you can set the BRI Analog Encode parameter to
specify the encoding type. (For more information about this parameter, see the MAX Reference
Guide.)
Link Type
The Link Type parameter specifies whether the switch operates in point-to-point or multipoint
mode. In point-to-point mode, MultiVoice Gateway requires one phone number and no Service
profile Identifiers (SPIDs). In multipoint mode, the MultiVoice Gateway requires two phone
numbers and two SPIDs. All international switch types except DBP Telecom, and all U.S.
switch types except AT&T 5ESS, operate in multipoint mode.
Using the BRI line for switched or nailed connections
Each BRI line has two B channels for user data and one D channel for signalling. The B1 and
B2 Usage parameters specify how to use the B channels: Switched (the default), Nailed, or
Unused (not available for use).
Associating the channel with a slot/port in the MultiVoice Gateway
In the B N Slot and B N Prt/Grp parameters, you can assign a switched channel to a slot or
slot/port combination for a digital modem, AIM port, or Ethernet. This configuration affects
both inbound call routing and outbound calls. In effect, it reserves the channel for calls to and
from the specified slot or port.
Note:
You cannot control whether an incoming call rings on the first or second B channel, so
the B1 Slot and B2 Slot parameters should be set to identical values.
If the channel is nailed, B N Prt/Grp is a Group number. To make use of this nailed connection.,
the Group number is referenced in a Connection or Call profile.
Assigning the channel to a trunk group
You can assign trunk-group numbers 4 through 9 to channels to make them available for
outbound calls. You cannot combine PRI channels with BRI channels in the same trunk group.
