ISDN Flexible Behavior Parameters
ISDN protocol is implemented in different switches/PBXs by different vendors. Several
implementations may vary slightly from the specification. Therefore, to provide a flexible interface
that supports these ISDN variants, the ISDN behavior parameters can be used.
User's Manual
number. With NFAS, you can use a 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.

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 285.
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.
Notes:

This 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.
Notes:

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.

For more information on NFAS, see 'ISDN Non-Facility
Associated Signaling (NFAS)' on page 285.
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] = (Default) The call is disconnected.
Determines whether and which Progress Indicator (PI) information
element (IE) is added to the sent ISDN Setup message. Some
ISDN protocols such as NI-2 or Euro ISDN can optionally contain
PI = 1 or PI = 3 in the Setup message.

[0] = PI is not added (default).

[1] = PI 1 is added to a sent ISDN Setup message - call is not
end-to-end ISDN.

[3] = PI 3 is added to a sent ISDN Setup message - calling
equipment is not ISDN.
