Configuring the trunk direction and routing mode
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter E1 or T1 interface view. controller { e1 | t1 } number N/A
3. Create a timeslot set and
enable R2 signaling for it.
timeslot-set ts-set-number
timeslot-list timeslots-list signal r2 By default, no timeslot set is
created.
4. Enter R2 CAS view. cas ts-set-number N/A
5. Configure the trunk direction. trunk-direction timeslots
timeslots-list { dual | in | out }
The default is dual.
You cannot configure the in or out
direction on both ends of a trunk. If
you configure the dual direction on
both ends, you need to configure
different routing modes on the two
ends by using the select-mode
command to prevent timeslot
contention.
6. Configure the routing mode.
select-mode { max | maxpoll | min
| minpoll }
The default is min.
Configuring the terminating side to send busy tones to the originating side
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter E1 or T1 interface view. controller { e1 | t1 } number N/A
3. Create a timeslot set and
enable R2 signaling for it. timeslot-set ts-set-number
timeslot-list timeslots-list signal r2 By default, no timeslot set is
created.
4. Enter R2 CAS view. cas ts-set-number N/A
5. Configure the terminating side
to send busy tones to the
originating side. send ringbusy enable
By default, the terminating side
sends busy tones to the originating
side.
If you want the originating side to
play busy tones, execute the undo
send ringbusy enable command on
the terminating side.
6. Configure the duration for
playing busy or ringback
tones.
timer { ringback | ringbusy } time
By default, the duration for playing
a ringback tone is 60000
milliseconds, and the duration for
playing a busy tone is 30000
milliseconds.
This command takes effect only
after you configure the send
ringbusy enable command.
This command takes effect only on
the terminating side.
