Configuring R2 digital line signaling
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 sets exist. |
4. Enter R2 CAS view. | cas ts-set-number | N/A |
5. Configure the originating side to require the terminating side to send answer signals. | answer enable | By default, the originating side requires the terminating side to send answer signals. |
6. Enable reanswer signal processing on the originating side. | re-answer enable | By default, reanswer signal processing is disabled on the originating side. |
7. Configure the terminating side to send clear-back signals when the originating side first disconnects the line. | clear-forward-ack enable | By default, the terminating side does not send clear-back signals when the originating side first disconnects the line. |
8. Enable metering signal processing. | metering enable | By default, metering signal processing is disabled. |
9. Configure the originating side to require the terminating side to send seizure acknowledgment signals. | seizure-ack enable | By default, the originating side requires the terminating side to send seizure acknowledgment signals. |
10. Configure the ABCD bit pattern for line signals. | dl-bits { answer | blocking | clear-back | clear-forward | idle | release-guard | seizing | seizing-ack } { receive | transmit } ABCD | The defaults are the values of the ITU-T standard. For the default values, see this command in Voice Command Reference. |
11. Configure the C and D signal bits. | renew ABCD | The default depends on the R2 signaling standard (configured by using the mode command). |
12. Configure line signal inversion mode. | reverse ABCD | The default is 0000, that is, line signal inversion is disabled. |
13. Set the timeout time of line signals. | timer dl { answer | clear-back | clear-forward | | re-answer | release-guard | seizing } time | By default, the timeout time is:
