12. Configuration Parameters Reference
Indicates the NFAS group number (NFAS member) for the
selected trunk, where x depicts the Trunk ID.
0 = Non-NFAS trunk (default)
1 to 12 = NFAS group number
Trunks that belong to the same NFAS group have the same
number.
With ISDN Non-Facility Associated Signaling you can use
single D-channel to control multiple PRI interfaces.
Notes:
For this parameter to take effect, a device reset is
required.
This parameter is applicable only to T1 ISDN protocols.
For a detailed description on NFAS, see ''ISDN Non-
Facility Associated Signaling (NFAS)'' on page 643.
Defines primary, backup (optional), and B-channels only, per
trunk (where x depicts the Trunk ID).
[0] PRIMARY= Primary Trunk (default) - 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: This parameter is applicable only to T1 ISDN
protocols.
Defines a different Interface ID for each T1 trunk (where x
denotes the trunk ID).
The valid range is 0 to 100. The default interface ID equals
the trunk's ID.
Notes:
To set the NFAS interface ID, configure ISDNIBehavior_x
to include '512' feature per T1 trunk.
For a detailed description on NFAS, see ''ISDN Non-
Facility Associated Signaling (NFAS)'' on page 643.
Allows the device to ignore ISDN Disconnect messages with
PI 1 or 8.
[1] = The call (in connected state) is not released if a
Q.931 Disconnect with PI (PI = 1 or 8) message is
received during the call.
[0] = The call is disconnected (default).
Determines whether and which Progress Indicator (PI)
information element (IE) is added to the sent ISDN Setup
message. Some ISDN protocols such as Euro ISDN can
optionally contain PI = 1 or PI = 3 in the Setup message.
[0] = PI is not added (default).
