3. Briefly press the PTT switch to obtain a dial tone. A
successful access and busy or no access conditions
are indicated as described in Section 2.4.10.
4. When a dial tone is heard, enter the number to be
called in one of the following ways:
l Enter it directly using the 0-9 keys. If too much
time elapses between digits, the call is
terminated.
l If the microphone has a memory, it may be possi-
ble to recall the number from memory and dial it
automatically.
5. After the number is sent, landside ringing should be
heard (a landside busy condition could also be indi-
cated). When the other party answers, press the PTT
switch and respond. The PTT switch must be
pressed to talk and released to listen, the same as
with standard calls.
6. When the call is finished, press the # key to termi-
nate the call. Three beeps indicate that the call has
been terminated. Terminating the call in this manner
prevents extra billing that may occur for the time
required for the system to automatically detect the
end of the call.
Receiving a Telephone Call
1. Turn transceiver power on and set the volume as
described in Sections 2.4.1 and 2.4.2.
2. Select or scan the system and group programmed for
telephone calls. If equipped with a Telephone option
switch, it can be used to quickly select a telephone
group (see Section 2.8.5). When a group
programmed for telephone calls is selected, the tele-
phone symbol
is displayed).
3. When “ringing” is heard, press the PTT switch and
respond. The PTT switch must be pressed to talk and
released to listen as with a dispatch call.
4. When the call is finished, it should be terminated as
in step 6 of the preceding section.
Placing a Landside-To-Mobile Telephone Call
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.
