Valid Range and Description
Defines the trunk priority for auto-clock fallback (per trunk parameter).
0 to 99 = priority (0 is the highest = default).
100 = the SW never performs a fallback to that trunk (usually used to mark
un-trusted source of clock).
Fallback is enabled when the TDMBusPSTNAutoClockEnable
parameter is set to 1.
Enables and disables the PSTN trunk auto-fallback reverting feature. If a
trunk with a higher priority than the current LocalReference is being
synchronized, the board LocalReference changes to the new trunk.
0 = disable (default).
1 = enable.
The parameter is valid only in when the
TDMBusPSTNAutoClockEnable parameter is set to 1.
0 = use B8ZS line code (for T1 trunks only) default.
1 = use AMI line code.
2 = use HDB3 line code (for E1 trunks only).
Use to select B8ZS or AMI for T1 spans, and HDB3 or AMI for E1 spans.
Same as the description for parameter 'LineCode' for a specific trunk ID (x =
0 to 7).
Determines the ISDN B-Channel negotiation mode.
0 = Preferred
1 = Exclusive (default)
Applicable to ISDN protocols.
0 = Non NFAS trunk (default)
1 to 4 = NFAS group number
Indicates the NFAS group number (NFAS member) for the selected trunk.
'x' identifies the Trunk ID (0-7).
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.
Applicable only to T1 ISDN protocols.
0 = Primary Trunk (default)
1 = Backup Trunk
2 = NFAS Trunk
D-channel configuration parameter defines primary, backup (optional) and
B-channels only trunks.
'x' identifies the Trunk ID (0-7).
Primary trunk contains D-channel that is used for signaling.
Backup trunk contains backup D-channel that is used if the primary D-
channel fails.
The other NFAS trunks contain only 24 B-channels, without a signaling D-
channel.
Applicable only to T1 ISDN protocols.
Defines a different Interface ID for each T1 trunk.
The valid range is 0 to 100.
The default interface ID equals to the trunk's ID (0 to 7).
