T

he ST-865M3 may be operated in three modes; Radiotelephone, Fleet Dis-
patch and Conventional. The System Operator/Manager determines which of

these modes are made available to each subscriber.

The features of the operating modes are described below:

Radiotelephone - The subscriber receives private calls and group calls.
He can initiate telephone calls, call other radiotelephone subscribers and
call any group. Call records for each subscriber and group are main-
tained for billing.

Fleet Dispatch - The subscriber is assigned to two groups and receives
calls for both groups. If Automatic PTT is enabled, the subscriber can
call the main group by simply pressing PTT, with no keypad entry. The
subscriber may also initiate telephone calls, call radiotelephone subscrib-
ers and call any group. Call records for both groups are maintained for
billing.

Conventional - Subscribers have access to non-trunked radio channels
that operate as two way radio service. If this mode is enabled, mobiles
may switch from trunking operation to conventional by selecting a non-
trunked channel using the radio's channel select switch and then pressing
5* on the radio keypad.

2.1 Subscriber ID Numbers/Paging Code

Numbers

SmarTrunk II modes (Radiotelephone and Fleet Dispatch) are a function
of subscriber identification programming.

Each subscriber in a SmarTrunk II System may be assigned two Subscriber
ID Numbers. Subscriber ID numbers are similar to a telephone number.
This is the number a landline or radio caller uses to contact the subscriber.
As a security measure, this number is aliased to another number (Paging
Code Number) for over the air signaling. This security measure insures
that a radio listener cannot correlate any of the over the air signalling
with a number dialed. The Paging Code is expected to be a confidential
number known only by the System Operator/Manager and associates that
program the subscriber equipment. There is no requirement for the
subscriber to have knowledge of the Paging Code associated with the
equipment in use. The associated Subscriber ID Number provides
sufficient subscriber information necessary for all SmarTrunk II operation.
