P25 Digital Vehicular Repeater System
Motorola Solutions offers an MSI Certified APX compatible, third party, P25 Digital Vehicular Repeater
System (DVRS). This provides low-cost portable radio coverage in areas where only mobile radio coverage is
available.
NOTE: Portable subscriber units enabled in the system for Radio Authentication shall be able to
authenticate regardless of whether they are communicating directly on the system or by using a DVRS.
DVRS can also work with SmartConnect to use broadband coverage for the in-vehicle mobile. Portable
radios communicate through the in-vehicle mobile to the system through the LTE, Satellite, or Wi-Fi
connection. This extends the system coverage when you are away from the vehicle.

Conventional Talkgroup and Radio Scan
Enhancements
Enhancements have been made to the Conventional Talkgroup at the system to improve the Scan feature
operation significantly when multiple agencies are using a single conventional radio frequency channel.
These enhancements allow you to use Selective Squelch to operate on only the subset of talkgroups that are
relevant to the users rather than all talkgroups on the channel.
The enhancements support the following Scan mode:
●
Mixed Vote Scan.
●
Standard Conventional Scan.
●
Priority Operation.
Up to 30 different talkgroups can be supported using conventional channels. A maximum of four talkgroups
can be supported when Vote Scan channels are being used.
Smart PTT is supported with this enhancement as Smart PTT prevents you from transmitting while other
users are on the channel.
NOTE: User Selectable Talkgroups are not compatible with this Conventional Talkgroup Enhancement.
