DTMF-t SIGNALING
DTMF-t is an form of DTMF signaling that is compatible with most older forms of scan based
DTMF trunking. Both the Collect and Reset digits and timing are programmable in the Model 748.
The Reset digit and the timings for both are system wide settings. The Collect digit is part of the
Selcall capcode (the first digit of the capcode) when using this format. The default settings for this
format are:
DTMF-t Reset time:
1000msecs
DTMF-t Collect time:
2500msecs
DTMF-t Reset digit:
A
If a mobile has an decoder address of 1234, and the system is using a Collect digit of “D”, the Selcall
capcode would be “D1234”. Here is an example page using DTMF-t as the format, and D1234 as the
Selcall capcode.

On disconnect, the Reset digit will be sent to “reset” all the decoders on the channel. The Reset digit
will be sent also if the user receives a phone-to-mobile call, on disconnect of the call.
