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 pand 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 cbutton or the time-out expires or another group or system is selected.

4.To terminate the call, momentarily press the cbutton.
