PERATION
5-1:
The VX-Trunk II system operates in a full du-
plex mode.
In this environment, while a call is in progress,
the connected mobile passes the received au-
dio through to the VXR-1000 for re-transmis-
sion to the portable. In order for the portable
to be able to "capture" the VXR-1000 to make
a transmission back to the other party, the
VXR-1000 must be set, via the CE-22 software,
for a "Priority Timer" setting (Pri Timer) which
is not zero. A very short time will allow quick
interruption, but the incoming message from
the VXR-1000 to the portable may sound
"choppy" due to the frequent interrupts.
When the portable transmits longer than the
"Priority Timer" setting, the VXR-1000 will in-
terrupt its transmission, and the VXR-1000
will instantly switch to the "receive" mode on
the portable's transmitting frequency.
5-2: VXR-1000 Local Microphone
In order to facilitate the above sampling fea-
ture, it is not possible to use a "Local" mic (a
DTMF microphone attached to the VXR-1000)
for access to the VX-Trunk II system.
