Receiving LTR Telephone Calls
1. Select or scan the system and group programmed for
telephone calls. When a telephone group is selected,
the base portion
of the telephone icon is
displayed.
2. When “ringing” is heard, press the PTT switch and
respond. The PTT switch must be pressed to talk and
released to listen the same as with standard calls.
3. When the call is finished, it should be terminated as
in step 6 of the preceding section.
Landside-Originate Telephone Calls
Calls can be placed from a landside telephone to a
mobile transceiver (if the transceiver and radio system
have this capability). With most systems, a mobile
user can be called directly (each has a unique tele-
phone number). With others, the mobile being called
must be specified as follows:
1. Dial the number of the radio system in which the
mobile transceiver is operating.
2. When the system answers, a short tone sounds to
indicate that the number of the mobile being called
should be dialed. This number is usually five digits
long and must be dialed using a tone-type telephone.
The first two digits are the home repeater number of
the mobile, and the last three digits are the telephone
ID code of the mobile. With LTR interconnect
equipment, the first digit must be dialed within 5
seconds of hearing the tone, and no more than 5
seconds must elapse between digits or the call is
terminated.
3. Ringing is then heard by the landside caller while
the mobile is being rung.
