Configuring receive and transmit signaling
The ABCD bit pattern of the receive idle signal from the local end must be the same as that of the transmit idle signal from the remote end. Seized signals and idle signals are processed in the same way.
To configure receive and transmit 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 for digital E&M signaling and select a start mode. | timeslot-set ts-set-number timeslot-list timeslots-list signal { e&m-delay | e&m-immediate | 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-number:ts-set-number | N/A |
6. Configure the ABCD bit pattern of receive idle signal. | signal-value received idle ABCD | Optional. The default is 1101. |
7. Configure the ABCD bit pattern of receive seized signal. | signal-value received seize ABCD | Optional. The default is 0101. |
8. Configure the ABCD bit pattern of transmit idle signal. | signal-value transmit idle ABCD | Optional. The default is 1101. |
9. Configure the ABCD bit pattern of transmit seized signal. | signal-value transmit seize ABCD | Optional. The default is 0101. |
![[IMPORTANT: ]](images/important.png) | IMPORTANT: After you change the ABCD bit pattern of a digital E&M signal, shut down the digital E&M voice subscriber line with the shutdown command and then bring the line up with the undo shutdown command. Otherwise, the voice subscriber line cannot work correctly. | |
