If set to 390 ms or less, the DVR will wait
for MDC signaling to be decoded before
proceeding. If MDC is decoded DVR will
proceed
emergency handling, etc).
If set to 400 ms or more, the DVR ignores
PSU emergency retries for the duration of
the timer to allow proper processing of a
decoded MDC1200 emergency to the
system and sending of emergency ACK to
the PSU.
When programmed to 0, the MSU stays
on the steered mode after the PSU
inbound call is over.
If programmed to >0, the DVR forces the
MSU to return to the original MSU mode
when the PSU inbound call ends and the
programmed timer expires.
Specifies the type of MDC or TPS
signaling sent by the DVR to the Local
PSUs upon MSU Microphone PTT.
When enabled the DVR is capable of
handling P25 Encrypted calls while on
analog DVR channel.
Specifies the DVR repeat type when P25
Encrypted Outbound Calls are received
by the MSU and an Analog DVR channel
is selected.
When enabled (Simplex Analog DVR
channels only), the DVR will periodically
interrupt transmissions during System
outbound calls and check for PSU activity.
If PSU activity is detected, the DVR will
drop the outbound call repeat and give
higher priority to the PSU Inbound call.
