DVRS Installation & Programming Guide – PART II
Range
If enabled, a non-Primary DVR that
detects a valid Inbound or Outbound Call
will monitor for Primary DVR repeating the
call and if such is not detected, the non-
Primary DVR will repeat the call. The non-
primary DVR only temporarily repeats the
call and does not become a Primary when
Primary repeat is not detected. The first
few seconds of the Inbound or Outbound
Call are always lost while the non-Primary
DVR is checking for Primary repeat and
deciding if fallback is needed. MSU MIC
PTT will key up both the DVR and the
MSU.
Defines the analog audio buffer, which
prevents the loss of audio at the
beginning of transmission while the MSU
is acquiring channel grant. Longer time
value may cause the PSU user to hear the
tail end of his own transmission.
The DVR will add a user programmable
value/offset to the PSU MDC ID while
proxying a call to a P25 Trunking system.
Enables / Disables the PSU Voice
takeover when the MSU is receiving an
outbound call.
Enables / Disables the PSU Signaling
takeover when the MSU is receiving an

Enables / Disables the PSU call to be
upgraded from Local to System when the
MSU is no longer receiving an outbound
call and is allowed to transmit to the FNE.
