Configuring DTMF

Introduction to DTMF

To do...
Configure the wink start mode
for the E&M voice subscriber line
Configure the delay time from
when the terminating side
receives a seizure signal to when
it sends a wink signal in the wink
start mode
Configure the maximum amount
of time the originating side waits
for a wink signal after sending a
seizure signal in the wink start
mode
Configure the duration of a wink
signal sent by the terminating
side in the wink start mode
Follow these steps to configure the output gain of the SLIC chip:
To do...
Enter system view
Enter voice view
Enter voice subscriber line
view
Configure the output gain of
the SLIC chip
Dual tone multi frequency (DTMF) involves high frequency and low frequency
groups, each of which comprises four frequencies. A high frequency signal
overlaps a low frequency signal to form a combined signal and represent a digital
key. DTMF signaling has 16 codes used for dialing information input, enjoying
high interference resistance ability.
