Mobile Activity Time
During an interconnect call (mobile-to-phone, mobile-to-mobile), the mobile side must be in control
of the interconnect at all times (the mobile must be able to terminate the call). In order to insure that
the mobile is in control of the interconnect, the
Mobile activity timer guards against the mobile
getting out of range or for any other reason is unable to disconnect the call. A timer is initialized
every time the mobile keys up and the Model 748 sees carrier plus any required sub-audible decode.
If this timer is allowed to time out, the call is disconnected. The
Mobile activity timer is the time or
value that initializes this timer.
Single warning beeps are sent every 3 seconds starting 12 seconds before the Mobile activity timer
expires to warn the mobile that the call is about to be terminated. The mobile simply needs to key up
to reset the timer, thus keeping the conversation alive. When the timer expires, 5 short beeps are sent
to the telephone user and to the mobile user indicating that the call is over.
