View E1/T1 interface view

Parameter 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.

Description 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-numberkeyword in commands cas and timeslot-set.

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

Description 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.
