For robbed-bit signaling, set the line you are configuring to Trunk service, and set the signaling 
mode and the robbed-bit control mechanism. To configure a T1 line for robbed-bit signaling, 
proceed as follows:

Open a Net/T1 > Line Config > Line Config profile and, depending on which line you are 
configuring, set the 1st Line or 2nd Line parameter to Trunk. 

Open the subprofile for the line you have set to Trunk, and set Sig Mode to Inband. 

In the same profile, specify the Rob Ctl parameter to specify the robbed-bit call-control 
mechanism required by your carrier.   

Set the Framing Mode parameter to specify the physical-layer frame format of the T1 line.

Set the Encoding parameter to specify the type of encoding that the line uses at the 
physical-link layer.

Set the Send Disc parameter to specify the number of seconds the MAX unit waits, from 
the time the call is presented, before clearing the call.

Set the Overlap Receiving parameter to enable the unit to gather the complete called 
number from the network switch.

Exit the profile and, at the exit prompt, select the exit and accept option.

If the profile you have configured is not the active profile, activate it as described in 
“Activating a profile” on page 2-7.

Following is an example of T1-line configuration using all switched channels and the default 
inband (robbed-bit) signaling mode. (Only relevant parameters are shown.)

When you configure two T1 lines for NFAS signaling, they share a D channel. Configure one 
line with a primary D channel and the other with a secondary D channel. The secondary D
