DNIS and ANI collection for T1 using robbed-bit signalling
To configure DNIS/ANI collection for a T1 using robbed-bit signalling:
1
Open
Net/T1 > Line Config
profile.
2
Open the Line subprofile and set the signalling mode to Inband:
Line 2...
Sig Mode=Inband
3
configure Rob Ctl for either wink-inc-200 or wink-inc-400:
Rob Ctl=
wink-inc-200
Note:
If the value of Rob Ctl is set to Wink-Start, then Collect DNIS/ANI will be set to
N/A, preventing caller ID collection.

Collect DNIS/ANI=yes
5
Close the Line 1 subprofile.

Open the Line 2 subprofile and set the same values for these configuration values.
Using NFAS signalling
When you configure two T1 lines for NFAS signalling, they share a D channel. Configure one
line with a primary D channel, and the other with a secondary D channel. The MultiVoice
Gateway uses the secondary D channel only if the primary line goes down or if the MultiVoice
Gateway receives from the carrier’s switch a signal commanding a change to the other D
channel.
Note:
Both lines must reside in the same slot.
To configure two T1 lines for NFAS:
1
Open Net/T1 > Line Config and set both lines to Trunk service:
Net/T1
Line Config
Name=
1st Line=Trunk
2nd Line=Trunk
2
Open the Line 1 subprofile and set the signalling mode to NFAS:
Line 1...
Sig Mode=ISDN_NFAS
3
Keep the default NFAS ID:
NFAS ID num=1
4
Configure Channel 24 as the primary NFAS D channel:
Ch 24=NFAS-Prime
5
Close the Line 1 subprofile.
