Configuring the DTMF detection sensitivity
Use the dtmf threshold digital command to configure the DTMF detection sensitivity. A high DTMF detection sensitivity indicates a high tolerance of DTMF digits collection, a high probability of detection errors, and a low probability of DTMF failing to be detected.
To configure a DTMF detection sensitivity:
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 according to the selected signaling mode. | timeslot-set ts-set-number timeslot-list timeslots-list signal { e&m-delay | e&m-immediate | e&m-wink | fxo-ground | fxo-loop | fxs-ground | fxs-loop | r2 } | N/A |
4. Exit E1/T1 interface view. | quit | N/A |
5. Enter voice subscriber line view. | subscriber-line slot-number:ts-set-number | N/A |
6. Configure a DTMF detection sensitivity. | dtmf threshold digital value | Optional. By default, the DTMF detection sensitivity level is 0, that is, insensitive. This command is applicable to the BSV voice subscriber line, and is inapplicable to E1 and T1 voice subscriber lines. |
