1.2 Receiving A Call
The subscriber is alerted to an incoming call by ringing of the subscriber
equipment. This alerting takes four forms, related to the type of incoming
call.
a. A long single high frequency ring is generated by the logic board,
then a low frequency dual tone ring is generated by the controller.
This indicates an incoming landline call.
b. A short double high frequency ring is generated by the logic board,
then a low frequency dual tone ring is generated by the controller.
This indicates an incoming call from another SmarTrunk II radio
subscriber.
c. A short single high frequency ring is generated by the logic board,
then a double beep is generated by the controller. This indicates a
manually dialed group call.
d. A short single high frequency ring is generated in the calling radios
logic board, then a double beep is generated by the controller. This
indicates a (PTT) dispatch group call.
For items a and b, the subscriber must press * on the DTMF keypad to
answer the incoming call (Push-to-talk (PTT) is not pressed). For items c
and d, the subscriber may communicate with other members of the group
by pressing PTT (no answer action is required).
1.3 Call Routing Codes For Subscriber Initiated
Calls
Call routing codes are used for initiating a call from a subscriber to the
appropriate destination. Call routing codes are commonplace in PBX
telephone systems. For example, to place a call to an outside telephone
line through a PBX, a call routing code of typically 0 or 9 must be dialed
first. The SmarTrunk II system operates in a similar fashion, however, the
call routing code is placed at the end of the calling sequence.
The following table describes all the call routing codes. The subscriber
needs to be familiar only with the call routing codes that apply to their
application.
