TELEPHONE INTERCONNECT CALLS
Receiving A Telephone Interconnect Call (Trunked Mode Only)
Receiving a telephone interconnect call is identical to receiving an
individual call. See the DTMF Overdial Operation section if access to
services requiring "over-dial" is needed. Overdial operations are available
for any special call whether it is an individual call or a telephone
interconnect call.
Sending A Telephone Interconnect Call (Trunked Mode Only)
Use the following procedures to initiate and complete a Telephone
Interconnect call:
1. To select a previously stored phone number, select phone call mode
from the menu, press p and use the RAMP control , or . to
scroll through the list of stored phone numbers. The selection mode
rules apply. While in the phone call list, the m key will toggle the
display between the phone call name and the phone call number. If the
phone number is not stored in this list but the phone number is known, it
can be entered directly from the keypad. If necessary, a pause can be
entered by pressing and holding 0-9, *, or # until an underscore appears
in the display.
2. Press and release the PTT button; the radio performs the necessary
signalling to obtain a communication channel. When the signalling is
complete and the radio is clear to transmit, TX indicator turns on and the
channel access tone sounds. Line one shows the accompanying name if
selected from the list of stored numbers or the phone number if entered
directly. The message *PHONE* displays on line two. The radio then
automatically transmits the programmed number stored in the special
call queue.
3. The telephone ringing will be heard. When someone answers the phone,
press the PTT button and speak into the microphone. Release the PTT
button to listen to the caller. Unsuccessful interconnect signalling
returns the radio to the normal receive mode and the number remains
displayed until the special call is cleared by pressing the c button or
the time-out expires or another group or system is selected.
4. To terminate the call, momentarily press the c button.
