Default
The debounce time is 10 milliseconds.

Parameters
value: Specifies the debounce time for ring detection, in the range of 4 to 15 milliseconds.
Usage guidelines
This command is supported only on routers installed with the interface module SIC-1FXO, SIC-2FXO, or
HMIM-4FXO.
By setting different debounce times, you can detect ring signals of different frequencies and waveforms.
Do not set the debounce time during a conversation.
Do not set too short a debounce time. Otherwise, false detection might occur under the influence of
power line interference.
If you configure this command on an FXO interface of a card, the configuration takes effect on all FXO
interfaces of the card.
Examples
# Configure the debounce time for ring detection as 15 milliseconds on FXO interface 2/2/1.
<sysname> system-view
[sysname] subscriber-line 2/2/1
[sysname-subscriber-line2/2/1] ring-detect debounce 15
ring-detect frequency
Use ring-detect frequency to set the frequency value for ring detection.
Use undo ring-detect frequency to restore the default.
