Mobile Mode Steering; Steering And Emergency; Mixed Dvr Mode - Futurecom Mobexcom P25 Installation & Programming Manual

Note: The Mobile Detector feature allows a non-Priority DVR to repeat inbound PSU
call when no Priority transmission is detected, however, the DVR does not become a
Priority unit during Mobile Detector processing. The DVR can become a Priority unit
only as a result of the standard DVR Priority voting algorithm (exchanging of 'Heart
Beats').

Mobile Mode Steering

This feature allows a PSU User to remotely change the currently selected MSU mode by
transmitting with a pre-programmed PL/DPL. When the DVR decodes the PL/DPL it
finds the corresponding MSU mode in its look-up table and steers the MSU to the new
mode. Depending on the programming, the MSU may either stay on the new mode or it
may revert after a preprogrammed timer expires to the originally selected MSU mode.

Steering and Emergency

If steering is disabled on the current DVR channel, LPSU emergency is declared on the
currently selected MSU channel (no steering).
If steering is enabled on the current DVR channel, the LPSU emergency is declared on
the new (steered) MSU mode.
When MSU is in emergency call state
channel' is enabled), LPSU calls handling is defined by the
programming for the specific DVR channel. If
DVR repeats LPSU calls on the emergency channel (no steering occurs).
If 'Steering in Emergency'
this case the MSU will re-declare Emergency call on the new (steered to) channel.
If 'Put MSU in Emergency on Analog DVR channel'
programmed for Emergency Alarm only), an inbound LPSU call initiated while the MSU
is waiting for emergency ACK, should terminate MSU emergency and steer the MSU to
the corresponding MSU mode/channel without re-declaring the emergency alarm on the
new MSU channel.

Mixed DVR Mode

When a DVR Channel is programmed to operate in Mixed Mode, the DVRS can handle
calls from both P25 and Analog Local PSUs while the same DVR channel is selected on
the O5 / O3 / M5.
When Mixed Mode is selected, the DVR can be toggled between Digital and Analog
Mode as follows.
The default DVRS mode is Digital i.e. the P25 modem is enabled by default. If a Call
from a Local PSU is detected and the DVR does not decode a P25 Frame sync within
the preprogrammed 'P25 Frame Sync Detection
Mode and starts decoding Analog Mode signaling (such as DTMF, MDC1200 etc.). The
DVR enables the repeat of Analog signals to the Local Analog PSUs. After the Local
PSU keys off, the DVR stays in the Analog Mode for the duration of the preprogrammed
'VR Ch Mixed Mode Hold Timer'.
prior to the above timer's expiration will be repeated by the DVR as Analog
Conventional. Once the
back to Digital Mode and any Outbound calls are repeated as digital.
