8A083X30 Rev.11 APX Series P25 Interface DVRS User’s Guide Notations Used in This Manual The following notations are used throughout this document: NOTE: A clarifying statement that expands on the text that follows. IMPORTANT! An important statement that should be considered and / or implemented in order to achieve adequate equipment operation.
8A083X30 Rev.11 APX Series P25 Interface DVRS User’s Guide Declaration of Conformity This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
Futurecom requires the P25 DVRS operator to ensure FCC/ISED Requirements for Radio Frequency Exposure are met. The minimum distance between all possible personnel and the body of the DVRS equipped vehicle is specified in the “RF Safety” book shipped with the DVR. Failure to observe the Maximum Permissible...
Installed in the trunk of a car, fire truck, armored vehicle, ambulance or configured as a Transportable or Fixed mount DVR, the P25 DVRS extends radio communications when the PSU users are outside of the vehicle, inside a nearby building or in any portable radio marginal coverage areas.
Cross-Band Cross-Band DVRS models do not include any filters on the MSU side since the MSU and DVR are not intended to simultaneously operate in the same frequency band. In single band MSU configurations the MSU and DVR operate in different frequency bands.
DVR. IMPORTANT! The DVRS is shipped equipped with custom filters tuned to the specified frequency range provided by the Customer. Programming the DVR / MSU to operate on frequencies outside of the original specified bands may result in intermittent or complete loss of communications.

When both the MSU and DVR are configured to operate in the same frequency band, the DVRS requires a special set of filters including and in-band filter placed at the MSU antenna port. The special in-band filters are required in order to prevent interference when the DVR and MSU are activated at the same time.
DVRS User’s Guide Suitcase Mount DVRS The DVRS is packaged in a durable suitcase and includes all necessary electronics and filtering. The unit can be easily deployed in the field and is powered up either by plugging into an AC outlet or by using an optional battery backup kit. The battery backup kit is also packaged in a suitcase for ease of transportation.
IMPORTANT! Depending on the selected personality settings and configuration capabilities of the complete radio system infrastructure, the features / options described throughout this document may or may not be applicable to the specific DVRS operation. January 2019 Page 23 of 94...

P25 Trunking or Conventional System, i.e. without a DVRS. In in-band DVRS applications, the Local and System PSUs may be of the same model and personality. When a ‘DVR Enabled’ P25 Mode is selected, the PSU is referred to as Local PSU.
• The same Digital DVR channel is selected on both the PSU and the DVRS. Generic P25 PSU is registered during the first Group Call made after switching to the DVR enabled Mode. ‘DVRS Enabled’ P25 PSU starts automatic affiliation process upon selection of DVR Enabled Mode (no PTT required to start affiliation process).
When the DVR is in the process of handling a voice or signaling request for a PSU and another Local PSU initiates a Signaling request, the DVRS will respond depending on its programming and as described in Table 16 and Table 17 below. PSU Emergency Alarm is considered High Priority Signaling.
PSU Emergency Alarm is considered high priority signaling. All other PSU signaling (such as Status, Message etc.) is considered low priority. Voice Proxy Request Interactions with Voice Proxy are handled by the DVRS as programmed, see Table 19. New Request...

Local PSU selects TG1 while the MSU is on TG2, the Local PSU can talk to Local TG1 users as well as System TG1 users via the DVRS i.e. the MSU will be transmitting on TG1. If the MSU microphone is PTT-ed, both the MSU and the DVR will transmit on the TG selected on the MSU i.e.
‘Go Ahead’ tones are generated in the ‘DVRS Enabled’ PSUs. Different tones are generated to indicate if the DVRS is in Local or System Mode or the call is P25 Encrypted. As a programming option Local Mode tones can be generated when the System is busy and only Local repeat is available.
P25 Over The Air Rekeying (OTAR) is supported through the DVRS when the Local PSUs are of the ‘DVRS Enabled’ type, the DVRS is in the SYSTEM mode and the MSU is on a P25 Trunking mode. OTAR is not supported if generic P25 PSUs are used and / or if the MSU is on a P25 conventional channel.
The DVRS extends this functionality to the ‘DVRS Enabled’ Local PSUs when the DVRS is in the SYSTEM or LOCAL mode and the MSU is operating on a P25 trunked channel. PSU Reprogram request (PSU requesting to be dynamically regrouped...
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 cannot support encryption key translation. When the DVR is on a P25...
All DVRS should have unique IDs programmed in the digital mode settings menu if the remote control feature is to be used. If no DVRS ID is programmed, the DVR will assume the ID of the MSU currently interfaced to it. Remote activation and steering are supported when the MSU ID = DVR ID.
