Enabling the DTMF mode to receive and send R2 signaling
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter E1/T1 interface view.
controller { e1 | t1 } slot-number N/A
3. Create a TS set and enable R2
signaling for it.
timeslot-set ts-set-number
timeslot-list timeslots-list signal r2
N/A
4. Enter R2 CAS view.
cas ts-set-number N/A
5. Enable the receiving and
sending of R2 signaling in the
DTMF mode.
dtmf enable
Optional.
By default, R2 signaling is received
and sent in the multi-frequency
compelled (MFC) mode.
6. Configure the delay before
sending DTMF signals.
timer dtmf time
Optional.
The default is 50 milliseconds.
You must configure the dtmf enable
command before this command.
Configuring the connection mode for an R2 call
There are two connection modes for an R2 call: terminal-to-terminal (terminal) and segment-to-segment
(segment) mode.
• In the terminal-to-terminal (terminal) mode, after the called number is received, the R2 protocol
module must wait for the real state (busy or idle) of the called party before returning the
corresponding register information to the originating side.
• In the segment-to-segment (segment) mode, after the called number is received, the R2 protocol
module directly returns the "called party idle" register signaling, without waiting for the real state
of the terminating side.
To configure the connection mode for an R2 call:
Step Command Remarks
1. Enter system view.
system-view N/A
2. Enter E1/T1 interface view.
controller { e1 | t1 } slot-number N/A
3. Create a TS set and enable R2
signaling for it.
timeslot-set ts-set-number timeslot-list
timeslots-list signal r2
N/A
4. Enter R2 CAS view.
cas ts-set-number N/A
5. Configure the connection
mode for an R2 call.
callmode { terminal | segment }
Optional.
By default, the
terminal-to-terminal
(terminal) mode is adopted.
