User Timers:
These timers are not normally used by the controller. They are provided for your use. You can
start them running by executing Command 022 and stop them with 023 (or they will stop
automatically when they expire). Also, when one of these timers expires, the corresponding event
trigger (see Chapter 20) is automatically fired. This allows you to start these timers when certain
things in the controller happen and do something when the timer expires. These timers are
programmed in one second increments.

DTMF Interdigit Timers or Auto-execution timers (See Command 078):
These timers are used to get rid of stray DTMF digits after several seconds without entering any
more digits. For example, if you key and press a DTMF digit, then start talking, this timer will
throw that digit away after a default of 5 seconds. That way if, after you talk a while, you try to
enter a command, the digit you entered 30 seconds ago won't mess it up. Of course if you unkeyed
during that time, all of the digits would be either executed or discarded anyway. This also reduces
problems caused by voice falsing the DTMF decoder, by discarding the incorrectly received digits if
no more digits are received during the length of this timer. This timer starts running when the
DTMF digit is released, so you can hold a DTMF digit as long as you like without it being
discarded.
