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

2. Enter E1/T1 interface view.

controller { e1 | t1 } slot-number

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.

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.
