System Channel
Acquisition Time
600
– 6000
ms
Determines the DVR wait time for
the system grant before the DVR
decides what tones (ACK or NACK)
must be sent to the Local PSUs
and starts local repeat.
This timer also determines the
maximum number of retries that
will be made by the DVRS in
order to acquire a system
channel. These retries are sent
every second so if the intent is to
allow 2 retries, the timer needs to
be set to 1800
– 2000ms in order
to allow sufficient system
response time.
This VR ID
number
Specifies the ID of the DVR, which
is used for remote DVR mode and
TG change. If not specified, the
DVR will assume the ID of the
currently interfaced MSU.
Refer to the
