<time> specifies the duration of each tone in 180-millisecond unit. Default value
is 1 for 180 ms.
For example, the command string –MSVTS=1,[9,2],[5,3] will:
1. Generate DTMF 1 with a duration of 180 ms (default)
2. Generate DTMF 9 with a duration of 360 ms (2 * 180 ms)
3. Generate DTMF 5 with a duration of 540 ms (3 * 180 ms)
Test Command:
–MSVTS=?
List the supported parameter settings. The response is in the form:
–MSVTS: (supported <tone>s),(supported <time>s)
Note:
DTMF generated with the –MSVTS command is never played back locally as
tones and is therefore neither played nor muted under control of the –MSVLS
command.

0
Receiving of DTMF disabled (default)

Receiving of DTMF enabled
If receiving DTMF is enabled, the A3LA-R/RM/RGS sends the following unsolicited
result code every time a DTMF inband signaling data is received from the network
while in a voice call:
–MSTRX: <tone>,<event>
where <tone> is the DTMF tone received (‘0’-’9’, ‘#’, ‘*’, ‘A’-’D’) and <event> can be
one of the following:
0
tone stopped (i.e. key released)
1
tone started (i.e. key pressed)
