Dynamic Regrouping; Phone Interconnect; Adaptive Power Control; Audio Buffering - Futurecom Mobexcom P25 Installation & Programming Manual

System design must ensure that PSU TGs that are programmed for TG Translation
are NOT patched.
MSU Patch is supported as follows:
Inbound call from PSU on TG Translation enabled TG will be translated to the patch
supergroup and repeated locally and to the system.
Outbound call will be repeated as is (with the supergroup TG ID).

Dynamic Regrouping

The System Dispatcher can temporarily assign selected individual radios operating on
different TGs to operate on a new dedicated TG. The DVRS extends this functionality to
the 'DVRS Enabled' Local PSUs when the DVRS is in the SYSTEM or LOCAL mode.
NOTE:
Dynamic Regrouping is not supported on Generic P25 PSUs.

Phone Interconnect

Phone Interconnect is supported on Local P25 'DVRS Enabled' PSU when the DVRS is
on a full duplex P25 channel (digital or mixed mode) and the MSU is on a P25 Trunked
mode. Phone Interconnect requires the DVR to be in the System or Local mode.

Adaptive Power Control

The DVRS sends P25 messages to the Local 'DVRS Enabled' PSUs to adjust their
transmit power depending on the received signal strength and thereby to conserve the
PSU battery. This feature is not supported on Generic P25 PSUs.

Audio Buffering

Audio buffering is supported by the DVRS in order to eliminate loss of messages / parts
of messages due to the inherent delays associated with acquiring system access.

P25 Encryption

The DVRS transparently passes the P25 encryption algorithms used by the subscriber
and fixed network equipment. Even though the DVRS can be programmed to support
TG translation, it can not support encryption key translation.

Remote DVR Activation and Steering

Call Alert (Page) to DVR

A P25 PSU may be programmed to send a Call Alert (Page) and preprogrammed NID to
a specific DVRS and thereby remotely change:
DVRS Mode (from OFF or Local to System)
DVR Status (Secondary / Primary)
Selected TG / Channel on MSU
IMPORTANT
Remote change of MSU TG has no effect on the operation of the rest of the PSUs
in the area since the TG Proxing feature allows multiple TG operation. However, if
the PSU remotely steers the MSU to a conventional channel, other PSU users will
not have trunking system access.
