Direct Enhanced Full Duplex Phone Interface CP0070/XCP0070
The Direct Enhanced Full Duplex option allows the operator to use the Navigator to place and receive
calls from the public switch telephone network, PSTN, or a private branch exchange, PBX. 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 Direct Phone Interface
To place an outgoing phone call from normal
operation, press the toolbar
PHONE button. This takes
the phone off-hook, highlights the PHONE button
indicator, and opens the Phone window as shown.
Audio from the phone is directed to the select speaker
while the phone is in use. Audio from the selected
channel is directed to the unselect speaker and the
selected channel’s
SELECT button flashes to indicate
the selected channel audio is no longer at the select
speaker.
The numeric pad can now be used to dial the desired
number. The number entered is displayed on the right
side of the second line of the information window as it is entered. If an error is made in dialing, hang up
using the toolbar
PHONE button, and begin again.
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 the handset PTT. The operator continues to hear the
phone caller’s voice during transmission, but the phone caller doesn’t 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
TRANSMIT buttons to
transmit on a channel other than the selected channel.
