ICP9000 Navigator Series Console Operator’s Manual Options
55 12/10
External Enhanced Full Duplex Phone Interface CP0060/XCP0060
The External Enhanced Full Duplex Phone Interface option allows the operator to use the ICP9000
Navigator to place and receive calls with an external phone. This option supports full duplex phone
conversation when used with a headset or handset. Also included with this interface are the phone patch
and radio patch options.
Using the External Phone Interface
If the external phone activates the off-hook request while the console is in the normal operation, the
console immediately switches to phone mode, activating the toolbar
PHONE indicator and opening the
phone window. If the console is not in normal operation mode (radio patch, multi-select, page, etc.), or
any button is pressed on the console when the off-hook request is activated, the phone cannot be used and
the toolbar
PHONE indicator flashes. Once the console returns to normal mode or the button is released,
the console immediately switches to phone mode.
The full-duplex nature of the phone audio path is controlled dynamically and is dictated by the type of
microphone being used by the operator. If the phone is off-hook and the operator is using a headset or
handset, the audio path between the operator and the phone is full-duplex and the operator and phone
caller can converse as with a normal telephone. The operator can transmit on the selected channel by
using the main
TRANSMIT button, the headset or handset PTT. The operator continues to hear the phone
caller’s voice during transmission, but the phone caller does not hear the console operator’s voice. This
type of operation would normally be used to dispatch a police officer to the location of the phone caller
in the event of an emergency. The console operator can also use the channel
TX buttons to transmit on a
channel other than the selected channel.
If the operator is using the gooseneck or internal microphone and has activated the select speaker off-
hook override or phone patch, the audio path between the operator and the phone is forced to half-duplex.
This removes the possibility of feedback between the microphone and speaker. The operator must use
the
TRANSMIT button, the headset or handset PTT to talk to the phone when half-duplex mode is active.
The operator must use the channel TRANSMIT button to transmit on any channel. While transmitting on
a console channel, the console operator’s voice audio is not heard by the phone caller, but the operator
continues to hear the phone caller’s voice. To mute the phone caller’s voice, the call must be placed on
hold with the external phone.
While the phone is in use, certain modes of operation may be restricted. Placing the caller on hold using
the
PHONE HOLD button will allow all console functions to be accessible and the console will operate as
if the phone were not in use.
Phone Patch with External Phone Interface
Phone patch operation is available with the external phone interface and operates as described in the
Direct Enhanced Phone Interface section of this manual.
