Model ST-865M3 SmarTrunk II™ Logic Board
This section describes the advanced SmarTrunk II dialing methods. Dialing
has an automatic five second time-out. If the time between pressing keys
in a dialing sequence exceeds five seconds, the ST-865M3 times out. A
low frequency beep will be heard and the dialing procedure must be
restarted. To clear out previously entered data and restart dialing, press
the # key.
A busy tone will be heard by the subscriber if connection is not possible.
This can occur if a radio channel is not available, or if the subscriber unit
is out of range. The subscriber must then retry the call at a later time, when
within range and a radio channel is available.

Routing code 9 calls the subscriber that is preprogrammed
as the Mobile Operator. This functions as though the sub-
scriber had used routing code 3 with the subscriber ID num-
ber of the Mobile Operator. The Mobile Operator is pro-
grammed by the System Operator/Manager.
Routing code 0 causes the ST-852M to access line 1 and dial
the preprogrammed emergency phone number. The emer-
gency phone number is programmed by the System Opera-
tor/Manager.
See the ST-852M SmarTrunk II Digital Trunking Control-
ler Manual for details on programming the emergency num-
bers.
