E1/T1 interface view

ts-set-number: Number of a created timeslot (TS) group, in the range of 0 to 30. 
The number of a T1 timeslot group ranges from 0 to 23.

Use the cas command to enter R2 CAS view, digital E&M signaling view, or digital 
LGS signaling view.

After entering a signaling view, you may configure signaling parameters as 
desired. When doing that, assign the same value to the ts-set-number keyword in 
commands cas and timeslot-set.

timeslot-set, ani-offset, reverse, select-mode, timer, trunk-direction, and 
renew.

Use the clear-forward-ack enable command to enable the terminating point to 
respond with a clear-back signal when the originating point (the calling party) 
disconnects a call.

Use the undo clear-forward-ack enable command to disable the terminating 
point to respond with a clear-back signal when the originating point (the calling 
party) disconnects a call.

By default, the terminating point does not send clear-back signals to acknowledge 
clear-forward signals.

This command applies to R2 signaling only.

In some countries, if the terminating point controls trunk circuit reset in the R2 
signaling exchange process, when the calling party disconnects a call and the 
originating point sends a clear-forward signal to the terminating point, the 
terminating point sends a clear-back signal as an acknowledgement, and then 
sends a release guard signal to indicate that the line of the terminating point is 
thoroughly released.
