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-number keyword in
commands cas and timeslot-set .
Related command: timeslot-set , ani-offset , reverse , select-mode , timer, trunk-direction , and
renew .
Example # Enter the R2 CAS view of TS group 5.

Parameter None
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.
