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 HPE FlexNetwork MSR Router Series Comware 5 Voice Command Reference.
To configure the delay 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 delay start mode. | timeslot-set ts-set-number timeslot-list timeslots-list signal e&m-delay | 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 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. |
To configure the wink 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-wink | 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 maximum time the calling party waits for wink signal after sending the seizure signal in wink start mode. | delay wink-rising millseconds | Optional. The default is 2,000 milliseconds. |
7. Configure the maximum duration of the wink signal sent by the called party in wink start mode. | delay wink-hold millseconds | Optional. The default is 500 milliseconds. |
8. Configure the minimum delay the called party must wait before sending a wink signal in wink-start mode. | delay send-wink millseconds | Optional. The default is 200 milliseconds. |
