Configuring ISDN BRI network cards
Configuring the B channels
Each BRI line has two B channels for user data and one D channel for signaling. To configure
the B channels, open a Net/BRI > Line Config profile, then open the line's Line N subprofile
and set the following parameters:
Parameter
B1 Usage
B2 Usage
B1 Slot
B2 Slot
B1 Prt/Grp
B2 Prt/Grp
B1 Trnk Grp
B2 Trnk Grp
For detailed information about each parameter, see the MAX Reference.
BN Slot and BN Prt/Grp parameters
With the BN Slot and BN Prt/Grp parameters, you can assign a switched channel to a slot or
slot/port combination for a digital modem, AIM ports, or the Ethernet port. The slot/port
combination 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. For details, see
"Configuring inbound calls" on page 3-59 and "Configuring outbound calls" on page 3-69.
Note: You cannot control whether an incoming call rings on the first or second B channel, so
set both BN Slot parameters to the same value.
If the channel is nailed, BN Prt/Grp is a Group number. To make use of this nailed connection,
the Group number is referenced in a Connection or call profile. (For the definition of call
profile, see "Assigning nailed channels to groups" on page 3-12.)
BN Trnk Grp parameter
You can set the BN Trnk Grp parameter to configure trunk-group dialing for outgoing calls on
BRI lines supported by the ISDN BRI card. You can assign trunk-group numbers 4–9 to
channels to make them available for outbound calls. You cannot combine PRI channels with
3-36
Specifies
Usage (Switched, Nailed, or Unused) of the first B channel.
Usage (Switched, Nailed, or Unused) of the second B channel.
Slot number for routing calls to the first B channel. Should have the same
setting as B2 Slot.
Slot number for routing calls to the second B channel. Should have the
same setting as B1 Slot.
For switched channels, a port number to be used with the B1 Slot
parameter for call routing purposes. For nailed channels, a group number,
which will be referenced from a call or Connection profile, assigning the
channels for a connection.
For switched channels, a port number to be used with the B 2 Slot
parameter for call routing purposes. For nailed channels, a group number,
which will be referenced from a call or Connection profile, assigning the
channels for a connection.
Trunk group to which to assign the first B channel. Makes the channel
available for outbound calls.
Trunk group to which to assign the second B channel. Makes the channel
available for outbound calls.
