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, refer to ISDN Non-Facility
Associated Signaling (NFAS) on page 566.
Defines primary, backup (optional), and B-channels only, per trunk
(where x represents 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, refer to ISDN Non-Facility
Associated Signaling (NFAS) on page 566.
This parameter is not applicable to BRI interfaces.
Enables Rx ISDN overlap per trunk ID.
[0] Disable = Disabled (default).
[1] Enable = Enabled.
Notes:
If enabled, the device receives ISDN called number that is sent
in the 'Overlap' mode.
The Setup message to IP is sent only after the number
(including the Sending Complete IE) is fully received (via Setup
and/or subsequent INFO Q.931 messages).
The MaxDigits parameter can be used to limit the length of the
collected number for device ISDN overlap dialing (if sending
complete is not received).
If a digit map pattern is defined (DigitMapping), the device
collects digits until a match is found (e.g., for closed numbering
schemes) or until a timer expires (e.g., for open numbering
schemes). If a match is found (or the timer expires), the digit
collection process is terminated even if Sending Complete
wasn't received.
For detailed information on ISDN overlap dialing, refer to ISDN
Overlap Dialing on page 566.
