Configuring digital E&M signaling
Configuring a start mode
Similar to analog E&M signaling, digital E&M signaling also provides three start modes: immediate-start,
wink-start and delay-start. The time sequence of digital E&M signaling is the same as that of analog E&M
signaling for all three start modes. The only difference is that analog E&M signaling transmits signaling
information through the level change of Tip and Ring line but digital E&M signaling adopts 4 bits of TS16
to transmit signaling information in the same way as R2 signaling.
To configure the immediate start mode:
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 for digital
E&M signaling and select the
immediate start mode.
timeslot-set ts-set-number timeslot-list
timeslots-list signal e&m-immediate
N/A
4. Exit E1/T1 interface view.
quit N/A
5. Enter digital E&M voice
subscriber line view.
subscriber-line slot-numbe:ts-set-number N/A
6. Configure the delay that the
calling party must experience
before sending DTMF digits in
immediate start mode.
delay send-dtmf millseconds
Optional.
The default is 300
milliseconds.
For more information about the timer dial-interval, timer wait-digit, timer ring-back, and delay
send-dtmf commands, see Voice Command Reference.
To configure the delay start mode:
Step Command Remarks
1. Enter system view.

2. Enter E1/T1 interface view.
controller { e1 | t1 } slot-number N/A
3. Create a TS set for digital
E&M signaling and select the
delay start mode.

N/A
4. Exit E1/T1 interface view.
quit N/A
5. Enter digital E&M voice
subscriber line view.

N/A
6. Configure the maximum
duration of delay signal in
delay start mode.
delay hold millseconds
Optional.
The default is 400 milliseconds.
7. Configure the delay that the
called party must wait before
sending a delay signal after it
detects a seizure signal.
delay rising millseconds
Optional.
The default is 300 milliseconds.
