3Com VCX V7122 SIP VoIP Gateway User Manual
Valid Range and Description
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.
Backup trunk is not supported for DMS PRI variants.
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).
'x' identifies the trunk ID (0-7)
Note: To set the NFAS interface ID, configure: ISDNIBehavior_x to include '512'
feature, per each T1 trunk.
Defines CAS protocol for each Trunk ID (x = 0 to 7) from a list of protocols defined by
the "CASFileName_Y" parameter.
For example:
CASFileName_0 = 'E_M_WinkTable.dat'
CASFileName_1 = 'E_M_ImmediateTable.dat'
CASTableIndex_0 = 0
CASTableIndex_1 = 0
CASTableIndex_2 = 1
CASTableIndex_3 = 1
Trunks 0 and 1 use the E&M Winkstart CAS protocol, while trunks 2 and 3 use the
E&M Immediate Start CAS protocol.
CAS file name (such as "E_M_WinkTable.dat") defines the CAS protocol. It is
possible to define up to 8 different CAS files by repeating the "CASFileName"
parameter. Each CAS file can be associated with one or more of the gateway trunks
using "CASTableIndex_x" parameter.
1 to 8. Indicates how many CAS protocol configurations files are loaded.
