DTMF Signal ON/OFF Duration:
DTMF signal ON and OFF durations can be programmed in case LCR is activated
or 8088 1 code is used, in other words when the system is regenerating DTMF
digits and then sending them to external lines.
8 7 7 6 4 0 1 N M
Parameters:
N
: 02 - 25
DTMF ON Duration (x 20 milliseconds)
M
: 07 - 25
DTMF OFF Duration (x 20 milliseconds)
Deactivation:
The default DTMF ON and OFF durations are 100 msec and 140 msec
respectively.
Notes:
Dialing 8776 4 01 * sets the DTMF durations as their default values.
DTMF Detection ON/OFF Time:
With this program DTMF Detection ON and OFF durations can be programmed.
These ON and OFF durations determine the minimum detectable ON and OFF
durations of incoming DTMF digits. If they are increased more than needed, the
system may not detect the dialled digits properly and the call can not be formed
since the system regenerates the DTMF digits and send them to the external lines
incorrectly.
8 7 7 6 4 1 1 N M
Parameters:
N
: 1 - 5
ON-Time (x 20 milliseconds)
M
: 1 - 5
OFF-Time (x 20 milliseconds)
Default Values:
N= 2 (40 msec) and M= 3 (60 msec).
Notes:
1. Dialing 8776 4 11* sets the times as their default values.
2. This program will be supported with the Net-Console release AAS.
