1.3.1 Subscriber To Landline Call

Routing codes 1 and 2 give the subscriber access to tele-

phone line one or two respectively. A subscriber may be

restricted from line 2, or there may not be two telephone

lines connected to the ST-852M. In this case, routing code

2 is not valid.

1.3.2 Subscriber To Subscriber Call

Routing code 3 allows the subscriber to place a call to an-

other subscriber or group of subscribers. The call is routed

through the ST-852M and does not use the telephone sys-

tem.

1.3.3 Fleet Dispatch (Subscriber) To Group Call

Routing code 4 allows the subscriber to place a call to the

subscriber’s own group. This functions as though the sub-

scriber had used routing code 3 with the subscriber ID num-

ber of the subscriber’s own group. When automatic PTT is

enabled, operation of the PTT initiates a group call to the

subscribers group using routing code 4.

1.3.4 Conventional Mode

Routing code 5 selects conventional mode. In this mode,

radio channel switch positions not used by SmarTrunk II

trunking channels may be programmed and used for con-

ventional two-way radio operations. This feature is enabled

or disabled during initial setup of the radio. Availability of

this mode is determined by the radio dealer supplying the

radio, or the System Operator/Manager.
