isdn-nfas-group-number
[NFASGroupNumber_x]
D-channel Configuration
configure voip > interface e1-t1 >

[ISDNNFASInterfaceID_x]
User's Manual
Defines the following:

Network Side: When to "forget" all existing TEIs and wait for
the User side to start a new TEI assignment procedure.
This is also applicable to static TEI.

User Side: When to start a new TEI assignment verification
procedure.
The valid values are (bit-field parameter):

Bit#0: LAYER1_DEACTIVATION

Bit#1: BRI_DL_RELEASED

Bit#2: TEI_0_P2MP_NET_SIDE
The default is 0x00.
Defines the ISDN Non-Facility Associated Signaling (NFAS)
group number (NFAS member), per trunk.

[0] = (Default) Non-NFAS trunk.

[1] to [12] = NFAS group number.
Trunks that belong to the same NFAS group have the same
number. With NFAS, you can use a single D-channel to control
multiple PRI interfaces.
Note:

For the parameter to take effect, a device reset is required.

The parameter is applicable only to T1 ISDN protocols.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.

For more information on NFAS, see ISDN Non-Facility
Associated Signaling (NFAS) on page 471.
Defines primary, backup (optional), and B-channels only, per
trunk.

[0] PRIMARY= (Default) Primary Trunk - contains a D-
channel that is used for signaling.

[1] BACKUP = Backup Trunk - contains a backup D-
channel that is used if the primary D-channel fails.

[2] NFAS = NFAS Trunk - contains only 24 B-channels,
without a signaling D-channel.
Note:

The parameter is applicable only to T1 ISDN protocols.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
Defines a different Interface ID per T1 trunk.
The valid range is 0 to 100. The default interface ID equals the
trunk's ID.
Note:

To set the NFAS interface ID, configure ISDNIBehavior_x to
include '512' feature per T1 trunk.

The x in the ini file parameter name denotes the trunk
number, where 0 is Trunk 1.
