Identifying Your DVRS Model

Frequency Band of OperationDepending on the frequency band of operation of the XTLTM 2500 / XTLTM 5000 MobileSubscriber Unit (MSU) and DVR, the DVRS models are classified as follows:

In-Band – when the MSU and DVR operate in the same frequency band. Cross-Band – when the MSU and DVR operate in two different frequency

bands.

In-BandThe following In-Band DVRS Model Groups are available:

DVR BAND OF OPERATION [MHz]

Table 2 In-Band DVRS Models

The in-band DVRS models are equipped with two sets of filters, which are required inorder to ensure interference-free operation when both the MSU and DVR aretransmitting and receiving simultaneously. The DVR is a full duplex repeater and isequipped with a duplexer, which provides sufficient isolation to prevent desense duringDVR repeat activation. The DVR duplexer also provides 40 dB isolation on the Mobileradio transmit / receive frequencies. The filters installed at the output of the MSU aredesigned to provide 40 dB isolation on the DVR transmit and receive frequencies.

IMPORTANTThe above filtering isolation must be complemented by 30dB minimum antennaisolation (between the DVR and Mobile Radio antennas) in order to ensureinterference-free operation. It is recommended that the Mobile antenna is mountedon the roof of the vehicle while the DVR antenna is mounted on the trunk.Each DVRS is shipped equipped with custom filters tuned to the specifiedfrequency bands – note the frequency range specified on the filter Labels.Programming the DVR / Mobile radio to operate on frequencies outside of theoriginal specified bands may result in intermittent or complete loss ofcommunications. Frequency changes may require filtering retuning orreplacement.

The In-Band DVRS models are also equipped with an RF Bypass Switch, whichbypasses the filtering at the output of the MSU when a “DVR – Disabled” TG is selectedon the O5 / O3 / M5 Control Head.

8M083X01 Rev. 166881013Y39



When a “DVR – Enabled” TG is selected on the O5 / O3, the RF Switch inserts the extrafilters between the MSU Antenna port and the MSU antenna to ensure interference-freeoperation.The complex in-band filtering is only feasible if sufficient frequency gap is presentbetween the DVR frequencies and the MSU frequencies associated with the “DVR -Enabled” TGs.For more information on the feasible filtering options, please refer to the DVRS OrderingGuides.

AVRAThe Automated VR Activation (AVRA) option enables automated DVR ON/OFF controltriggered by an external switch – portable charger, door switch etc.

If this option is desired, the external switch (provided by others) needs to be wired to oneof the following:

A dedicated VIP Input on the O5 Control Head or DEK.o The ‘Automatic VR Activation’ and ‘AVRA Uses VIP on CH’ selection

boxes in the DVRS Hardware Setup menu must be checked.o The corresponding VIP I/P must be enabled in the XTLTM2500 / XTLTM

5000 – refer to the Programming Guide provided by Motorola for detailedinstructions.

For detailed instructions on VIP wiring, please refer to the XTLTM2500 / XTLTM5000Installation Manuals available from Motorola.

‘Switch 1 Input’ on the DB15 of the DVR Auxiliary Cable (PN 7W083X06).o The ‘Automatic VR Activation’ selection box in the DVRS Hardware Setup

Menu must be checked.o The ‘AVRA Uses VIP on CH’ selection box in the DVRS Hardware Setup

menu must be left blank (unchecked).o The XTLTM2500 / XTLTM 5000 do not require special programming related

to the enabling of this option.

Status LightsThe Status Lights Option provides status identification capabilities. The Relay outputs inthe DVRS can be programmed to provide several status indications – ‘Master Light’,‘LOC Mode Light’, ‘SYS Mode Light’ or ‘DVR ON Light’ .The DVR then provides control input to an external switch which in turn toggles anexternal light.The external switch and light are not included with the DVR.The Light Switch Relay Coil “+” must be wired to +12V DC and the “-“ to thecorresponding Relay Output on the DB15 connector of the DVR Auxiliary cable PN7W083X06 (500mA Max).

External AlarmIn applications where the DVR is installed in a fixed 19” rack, the external alarms optioncan be enabled and the corresponding relay output wired up to an external logic systemfor monitoring and reporting of ‘low power’ or ‘overt temperature’ combined alarms.

Duplexer Bypass SwitchIf this option is installed, the DVR duplexer can be switched out whenever a simplexDVR channel is selected. This feature is only applicable to Cross-Band DVRSConfigurations and provides frequency plan flexibility. The Duplexer Bypass Switch iswired to Relay 1 (pin 6) of the Auxiliary cable connector and the DVR needs to beprogrammed accordingly.

8M083X01 Rev. 166881013Y39



DVRS Antenna InstallationAny DVRS Model requires the use of two antennas – one connected to the MSU andone connected to the DVR. For a list of approved DVR Antennas, please refer toAppendix 12.

IMPORTANTTo assure optimum performance and compliance with RF Energy Safetystandards, these antenna installation guidelines are limited to metal-body vehicleswith appropriate ground planes and take into account the potential exposure ofback seat passengers and bystanders outside the vehicle.

The MSU and DVR Antennas must be installed in such way as not to cause interference.All DVRS models require 30dB minimum Antenna Isolation between the DVR andMSU Antennas.It is recommended that the DVRS antennas are installed as follows: one antennamounted in the center area of the roof, the other antenna mounted on the trunk lid.

Before installing an antenna on the trunk lid: Ensure the distance from the antenna to the front surface of the rear back seat isgreater then the minimum distance specified in the “Product and RF Safety” Bookletfor the specific DVRS model and frequency band. Ensure the trunk lid is grounded by connecting grounding straps between thetrunk lid and the vehicle chassis.

To ensure compliance with RF Energy Safety standards, the antenna locations, gain andmaximum Transmit Power (for both the Mobile radio and the DVR) must be as specifiedin the “Product and RF Safety” Booklet shipped with the DVR.

NOTEThe DVRS antenna ports (both DVR and XTL sides) are mini UHF male and requireantennas with matching mini UHF female terminations.

Dispatcher Initiated Remote DVRS ActivationDispatcher can send a Call Alert (Page) to a specific MSU, which in turn causes DVRmode change in the following order: OFF-SYS-LOC-OFF.

If remote mode change is enabled in the MSU then the Call Alert Page feature must bemade available to the Dispatcher only. The rest of the System subscriber equipmentmust not have the Call Alert (Page) feature enabled since paging a specific MSUinterfaced to a DVR will toggle the DVR mode and may cause loss of vitalcommunications.To enable the DVRS Remote mode change in the MSU and only allow the Dispatcher touse Call Alert functionality, the ‘System Remote Activation / Deactivation’ box in theRadio Wide VRS/DVRS Tab must be checked.

It is recommended that remote mode change is disabled in the MSU and enabledin the DVR as described below.

To disable the DVRS Remote mode change in the MSU and enable this functionality inthe DVR, the ‘System Remote Activation / Deactivation’ box in the Radio Wide VRS/DVRS Tab must be unchecked and the DVR must be programmed with the ID ofthe dispatcher console in its VR Activation ID Data table. In this case only Pages fromthis specific ID (or IDs) will cause DVRS mode change.

In addition, the DVRS may send back a mode change status to indicate its current mode(OFF, SYSTEM, LOCAL). Only the Dispatcher Console can interpret those statusmessages if correctly programmed:

Status 1 = OFF modeStatus 2 = LOCAL modeStatus 3 = SYSTEM

The MSU also must be programmed to send Status 1, 2 and 3.

IMPORTANT: The MSU should have only one System Unit ID programmed for allDVRS Enabled Systems. If the MSU is programmed with different Unit IDs in differentSystems, then Call Alert Page may cause intermittent and unreliable DVRS modechange.

P25 Trunking OTAR via DVRSIf the PSU users require the P25 Trunking OTAR feature to work via DVRS, the MSUmust have the ‘Packet Data Capable System (PDS)’ Option enabled in thecorresponding Trunking System N Data screens.

SCAN ON/OFFTo suspend MSU Scan when DVR is ON (recommended):Scan Scan Configuration check “Suspend Scan on DVRS Active”When the MSU is programmed (recommended) to suspend SCAN when DVR is ON, thefollowing SCAN scenarios are available:

8M083X01 Rev. 166881013Y39



Page 15 of 79

If the DVR is in the SYSTEM or LOCAL Mode and the MSU User presses the SCANbutton on the Control Head he /she hears an invalid button press tone and the SCANfunction does not become active.

If the DVR is OFF or Disabled, the MSU User can press the SCAN button and activatethe SCAN function.Once the MSU is in SCAN:

If the DVR Mode is changed from OFF to SYSTEM or LOCAL, the SCAN issuspended.

If the DVR Mode is changed back to OFF, the SCAN resumes.

If the MSU is programmed to allow both SCAN and DVR to be activated at the sametime, the following rules apply:

If the MSU lands on a mode which is compatible with the selected DVR channelthen outbound calls are repeated to the Local PSUs.

If the MSU lands on a mode which is not compatible with the selected DVRchannel then the DVR is disabled and the outbound call is not repeated to theLocal PSU.

Inbound call from the Local PSU returns the MSU to the originally selected moderegardless of the SCAN programming in the MSU.

NOTE:When SCAN and DVR operation are allowed (by MSU programming), the strapping ofDVR channels to MSU modes must be disabled.

Programming the PSUs for DVRS OperationThe programming of the PSU depends on the PSU type and User requirements. Thefollowing paragraph describes the programming options related to DVRS operation forthe 3 main types of PSUs.

The following Portable Radios have modified firmware that allows enhancedcommunications with the DVR and support of an extended list of features.

PSU Models that can be ‘DVRS Enabled’ PSU Firmware Revision RequiredXTSTM1500 R9.00.00 and higher

Note: It is highly recommended to always usethe latest released PSU firmware to ensure allfixes and new features are included.

Programming the ‘DVRS Enabled’ PSU

The Conventional Personalities associated with DVR channels must have the followingASTRO System parameters set in order to support ‘DVRS Enabled’ PSU mode:Conventional Astro Systems Astro System ‘X’ DVRS Tab

The ‘DVRS Operation Enable’ Box MUST be checked.

In the APX PSUs the Conventional System Associated with the DVRS must have‘System Type’ set to ‘DVRS’.

Enable (check) the ‘Talk Permit Tone’ Box if Talk Permit Tones are required(recommended).Enable (check) the ‘Display Site Trunking’ and / or ‘Alert Site Trunking’ Boxes ifthose features need to be supported through the DVRS.Enable (check) the ‘Dynamic Regrouping Enable’ Box if this feature needs to besupported through the DVRS.Enable (check) the ‘TA when no DVRS Comms’ Box if automatic switching to TA modeis required when a PSU goes outside of DVRS coverage range. If this feature isdisabled, the PSU makes up to five attempts to access a DVRS before it gives up.Set the ‘Busy Update Time’ field to 30 seconds (default).Set the ‘Response Pending Time’ field to >3 seconds.Set the ‘Activation Wait Timer’ field to 3 minutes (default).Set the Multikeys as required (available when ‘Secure Equipped’ is checked andcodeplug is Multikey capable).

Conventional Conventional Personality ‘X’ ASTRO Talk Group Options TabEnable (check) the ‘Talkgroup’ Box.Select Strapped as ‘Selection Type’ (recommended).Specify the required Talk Group List and Talk Group ID.

IMPORTANT: The digital PSU can not talk through the DVRS (in digital mode) unlessthe selected conventional ASTRO PSU mode is programmed with a valid system TG IDor TG Translation is enabled.The PSU must affiliate through the DVRS! Therefore the PSU must be programmed witha valid ID and the selected mode on the PSU must be programmed with a valid TG ID orTG Translation must be enabled and the PSU TG ID must be programmed in the DVRSTranslation table.Typically the conventional ASTRO PSU Unit ID must be set to match that of the trunkingsystem PSU ID in in-band applications. In cross-band application the ASTRO PSU UnitID must be enabled in the P25 System in order to be able to affiliate and communicatedthrough the DVRS.If the PSU needs to support say 10 TGs via DVRS, then the PSU must be programmedwith 10 Conventional ASTRO personalities and each personality must be strapped to thecorresponding TG ID. Alternatively the PSU can be programmed with just one (or a fewTGs) and TG translation can be enabled in the DVR so that the PSU TG ID is alwaystranslated to the ID of the TG selected on the MSU Control Head.

8M083X01 Rev. 166881013Y39



Page 17 of 79

NOTE:TG IDs are programmed in the PSU conventional ASTRO Talk Group List in decimaland in the MSU Trunking personality in hexadecimal format.

Zone Channel Assignment Channels Specify the correct (matching the DVRchannel) frequencies, desired Conventional Personality (programmed as describedabove) and correct Tx and Rx NIDs, matching the DVR programming.

If P25 Trunking OTAR is to be supported, the following parameters need to be set up inthe PSU:

Radio Configuration Secure Configuration ASTRO OTAR: check the ‘ASTROOTAR Enable’ box.

Radio Configuration Secure Configuration Secure KMF Profile SecureKMF profile X (corresponding to the conventional personality used to communicate viaDVRS) Data Transport: ensure all settings match the system settings.

Radio Configuration Secure Configuration Secure KMF Profile SecureKMF profile X (corresponding to the conventional personality used to communicate viaDVRS) ASTRO OTAR Information: set ‘Response Kind’ to ‘Confirmed’, ‘Numberof Attempts’ to 8 and ‘Time Between Attempts’ to 45.

ASTRO Systems ASTRO System X (associated with the conventional personalityused to communicate via DVRS) Data ‘Packet Data Capable System (PDS)’ fieldis enabled (checked) and the ‘Packet Data Mode’ is set to FNE.

If Fireground (FG) signaling is enabled in the PSU, ensure that the programmed “TxVoice Type” (Analog or Digital) matches the type of corresponding DVR “FG Enabled”Channel (Analog or Digital).

Remote Talk Group Steering allows Local PSU user to remotely change the TG /Channel currently selected on the MSU..If Remote Talk Group Steering is required, the same DVR channel frequency pair mustbe programmed in the PSU and associated with different Conventional Personalities,which in turn are associated with different Talk Group IDs and unique Tx NIDs as shownin the example below:PSU PROGRAMMING DVR PROGRAMMINGDVR CH TG

Programming of Generic P25 PSU for Digital DVRS ModeThe programming of a Generic P25 PSU requires matched DVR – PSU programming of:

DVR Tx and Rx Frequencies Tx and Rx NIDs (NACs) TG IDs

IMPORTANT: The digital PSU can not talk through the DVRS (in digital mode) unlessthe selected conventional ASTRO PSU mode is programmed with a valid system TG ID.The PSU must affiliate through the DVRS! Therefore the PSU must be programmed witha valid ID and the selected mode on the PSU must be programmed with a valid TG ID.Typically the conventional ASTRO ID of the PSU must be set to match that of thetrunking system PSU ID.If the PSU needs to support say 10 TGs via DVRS, then the PSU must be programmedwith 10 Conventional ASTRO personalities and each personality should be linked(strapped) to the corresponding TG ID.

Programming of the P25 PSU (Generic P25 or DVRS enabled) for operationon Conventional P25 MSU SystemBoth PSU types must have the Tx and Rx NACs matched with those programmed in theDVR.The ‘DVRS Enabled’ PSU needs to be programmed as described in the ‘Programmingthe ‘DVRS Enabled’ PSU’ section. If the P25 Conventional system is not usingdedicated TG IDs then all system radios transmit with the default TG ID = 1. When thePSU is programmed as DVRS Enabled, the default TG ID = 2 and it must be changed toTG ID=1 in order to match the rest of the system radios. If the Conventional P25 Systemis using dedicated TG IDs, then the DVRS Enabled PSU must be programmed withcorresponding conventional personalities using the required TG IDs.In the Generic PSU, the default TG ID = 1 so it matches the rest of the system radios. Ifthe Conventional P25 system is using dedicated TG IDs then the Generic PSU must beprogrammed with corresponding conventional personalities using the required TG IDs.

Programming of the P25 PSU (Generic P25 or DVRS enabled) for InboundDigital TakeoverIf “Inbound Digital Takeover” is not enabled in the DVR, the ‘DVRS Enabled’ PSU willhave ‘Tx inhibited on carrier’ (equivalent to Smart PTT enabled). If “Inbound DigitalTakeover” is enabled in the DVR then the DVRS Enabled PSU should have Smart PTTDisabled so it can interrupt outbound calls provided it is using a different TG ID(proxying) from the TG currently selected on the receiving MSU.A Generic PSU must have Smart PTT disabled if “Inbound Digital Takeover” is enabledin the DVR.

Programming of Analog Conventional PSU for Analog DVRS ModeThe programming of any PSU for Analog Mode involves the following: PSU Tx Frequency and Tx PL/DPL must match the DVR Rx Frequency and Rx

PL/DPL. PSU Rx Frequency and Rx PL/DPL must match the DVR Tx Frequency and Tx

PL/DPL. Adjacent channel spacing programming of the DVR channel and PSU must be the

same i.e. either 12.5kHz or 25kHz. If MDC Emergency is to be used by the PSU, the PSU must have MDC1200

signaling enabled and the MDC1200 System Pretime must be set to 700-800ms.Preamble during pretime must NOT be enabled. If MDC1200 Emergency alarm isto be used when the MSU is on a trunked channels, the MDC ID (hex) must beallowed on the Trunking system side.

If DTMF signaling is used, the DTMF sequence programmed in the PSU must endwith a ‘*’ i.e. 123*.

DVR ProgrammingThe following paragraphs provide detailed DVR programming information.

IMPORTANTDo not change DVR settings unless fully familiar with the meaning of a specificoption.The Tweaker program reports any obvious errors and does not allow invalid datato be saved to the DVR, however, not all inconsistencies can be reported by theTweaker.Successful DVRS programming requires thorough understanding of the DVR,MSU and PSU programming as well as the specific User / System requirements.Only when all templates (DVR, MSU and PSU) are matched, the DVRS will operateproperly.For instance, changing the XTLTM5000 template may require corresponding updateof the DVR template, which in turn may require update of the PSU template.

Description Notes

Tx RSSI Th -60 to-110dBm

When a Secondary DVR detects arequest for DVR repeat and it doesnot detect any Heart Beats comingfrom the current Primary DVR, theSecondary DVR checks for activityon its Tx frequency (exceeding theTx RSSI Th) to determine if the lackof Heart Beat is due to the PrimaryDVR already repeating the Call. Ifno activity is found to exceed the TxRSSI Th the DVR will check againand if 3 heart beats are missed, theDVR will negotiate becoming aPrimary.


Rx RSSI Th -60 to -110dBm

The DVRs exchangePrimary/Secondary messages ontheir Rx frequency while idle.Before a Primary DVR sends out aPrimary Heart Beat (HB), it checksfor RF activity and HB exceedingthe programmed ‘Rx RSSI Th’ onthe Rx frequency. If the PrimaryDVR does not detect any RFactivity or HB exceeding the ‘RxRSSI Th’, it will proceed withsending a Primary HB. If it detectsHB exceeding the programmed ‘RXRSSI Th’, the Primary DVR backsoff and becomes non-Primary, onstand-by. If a HB is detected but itslevel is below the programmed ‘RxRSSI Th’ the DVR will stay aPrimary and send its HB. If itdetects RF activity on the Rxfrequency, the Primary DVR willpostpone the sending of its HB untilthe Rx frequency is clear to ensurethe HB can be successfully (withoutinterference) received by the otherDVRS.

Mobile Radio Channel SetupThe DVR Operation may be enabled on some MSU Talk Groups (TGs) and Disabled onothers as selected and programmed in the personality of the MSU interfaced to the DVR.The DVR must be ‘made aware’ as to which TGs are ‘DVR Enabled’ and which are ‘DVRDisabled’.The DVR can be used only on the MSU Modes listed in the Mobile Radio Channel Setupscreen accessible via Tweaker. The Mobile Radio Channel Setup data is extracted byfirst exporting the MSU data (using the Motorola CPS) and then importing the data byusing the Import Motorola CSV function of the Tweaker as described in the nextparagraph.Note the DVR Channel type compatibility with the various Modes programmed in theXTLTM 2500 / XTLTM 5000 as listed in Appendix 4 to 11.

Importing Motorola CSV FileAfter programming the XTLTM 2500 / XTLTM 5000 for DVRS Operation and exporting theCSV file using the Motorola CPS, the data needs to be imported into the DVR by usingthe Import Motorola CSV function of the Tweaker.Ensure that ALL MSU screens have been exported prior to importing a CSV file (nohidden fields!).Any change to the MSU programming may require exporting and importing of a CSV filein order to update the DVR programming personality to match that of the MSU.

Defines the DVR ON/OFF triggerpolarity when an external switch iswired to pin 1 of the DB15 connector onthe DVR Auxiliary cable (7W083X06-01).

Applicable when the DVRON/OFF activation trigger iswired to the DVR Auxiliarycable. Not applicable when theDVR ON/OFF trigger is wired tothe mobile radio CH VIP.

Low BatteryAlarm

OFF – 13Volts

When the DC supply voltage drops 0.5Vabove the programmed threshold, a‘BATTERY LOW’ warning will bedisplayed. If the DVR is operating inAnalog Mode it will send warning tonesto the portables over the air. If thevoltage drops below the programmedlevel, the DVR is disabled and‘BATTERY LOW’ alternates with ‘VRERROR’ on the O5 / M5 display and theVR Transmitter is inhibited.When the battery voltage reaches 0.8 Vabove the programmed level the alarmcondition is reset and the DVR resumesnormal operation.

Typical setting is 10V.

PSU ID DataThis menu screen is used to specify PSU IDs (or range of IDs) that are allowed to beaffiliated on the system via DVRS. If analog portables are used and MDC ID passthrough is required, then the PSU MDC ID must be enabled on the System and includedin the PSU ID Data list of the DVR.If the range is set to be from ‘0’ to ‘- -‘, then any PSU ID is allowed to talk through theDVRS.This screen is Password protected. To view the range of IDs the User needs to enter apassword. To change the PSU ID list the User needs to log in as Admin (requirespassword).

VR Activation Radio ID DataThis screen allows the user to enter the console or system radio IDs range of units thatcan page the MSU and toggle the DVR mode. Default list is empty i.e. when the MSU ispaged the DVR mode is not changed provided the MSU is programmed to have theremote activation disabled (Radio Wide, ‘System Remote Activation/Deactivation’unchecked). If the ‘System Remote Activation / Deactivation’ box is checked in the MSUthen any Call Alert Page to the MSU will trigger DVRS mode change, which can result inloss of vital communications.

TG Translation ID DataTG Translation is used when the Local PSU needs to operate on more then 96 TGsand the System is P25 Trunking or P25 Conventional.When TG translation is enabled, the Local PSU transmits on TG A, which then istranslated by the DVRS to the TG currently selected on the MSU’s control head. TheLocal PSU can be programmed with just one TG (TG A) and it will talk on any TG that isprogrammed and selected on the MSU. The TG Translation ID Data Table allows theuser to program the Local PSU TG IDs that are enabled for TG Translation. The defaultlist is empty, i.e. TG translation is disabled. The Local PSU must be programmed withNormal squelch or NAC=F7E in order to be able to receive Outbound (System) or MSUMic PTT calls when TG Translation is enabled.NOTE: Encryption Key Translation is not supported by the DVRS.

Digital DVR Mode - Operation and Programming OverviewDigital DVRS Mode assumes the following:

Selected DVR channel is programmed for Digital or Mixed Mode.P25 PSU programmed for Digital DVR Operation and with Digital Mode currentlyselected (referred to as a Local PSU).A DVRS Enabled, P25 MSU Mode is selected on the O5 / O3 / M5.

The Digital Mode features supported by the DVR are listed in Appendix 4 & 5.The DVR Channel programming requires that Digital or Mixed Mode is programmed forthe specific DVR Channel and the Tx/Rx frequencies as well as the Tx/Rx NIDs of thePSUs and the DVR are matched.

NOTEForced Analog Mode is a hybrid mode in which the communications between the DVRSand the ‘DVRS Enabled’ P25 PSU are digital, while the voice communications are forcedto be analog. For more details, refer to Appendix 6 & 7 and the ‘Forced Analog DVRMode – Operation and Programming Overview’ section of this Document.

PSU AffiliationWhen a Local PSU User selects a DVR Enabled TG, the Local PSU is affiliated via anactive Primary DVRS if:

The DVR is programmed for Digital (or Mixed) mode on the selected DVRchannel.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 tothe DVR enabled Mode. ‘DVRS Enabled’ P25 PSU starts automatic affiliationprocess upon selection of DVR Enabled Mode (no PTT required to start affiliationprocess).

The maximum number of PSUs that can get affiliated with one DVRS is 256.

Group CallsInbound and Outbound Group Calls are supported by the DVRS as illustrated inAppendix 4 and Appendix 5.

Talk Group ProxingThe Local PSU User can change the selected ‘DVRS Enabled’ TG and seamlessly talkto the corresponding TG Users through the DVRS. The MSU can be on any ‘DVRSEnabled’ TG, which may or may not match the TG selected by the Local PSU.For example, if the Local PSU selects TG1 while the MSU is on TG2, the Local PSU cantalk to Local TG1 users as well as System TG1 Users via the DVRS i.e. the MSU will betransmitting on TG1. If the MSU microphone is PTT-ed, both the MSU and the DVR willtransmit on the TG selected on the MSU i.e. TG2.An outbound call received by the MSU on either TG1 or TG2 will be repeated by theDVRS to the Local PSUs.

8M083X01 Rev. 166881013Y39



Page 42 of 79

If Proxing is Disabled then the Local PSU and the MSU must have the same TGselected in order to enable Local PSU affiliation and communications.

Talk Group TranslationWhen TG translation is enabled in the DVR for a specific PSU TG ID, then any call thatis received by the DVR from the Local PSU with this TG ID will be translated to the ID ofthe TG currently selected on the MSU’s control head.The Local PSU could be programmed with just one TG ID and if this ID is programmedin the DVRS TG Translation list, the PSU call will always be translated by the DVRS tothe TG ID currently selected on the MSU control head.This feature is especially useful in applications where there is a need to support morethen 96 TGs on the Local PSUs (only up to 96 TGs can be programmed in theConventional ASTRO PSU).For instance, if the Local PSU is on TG A, which is programmed in the DVRS TGTranslation list and the MSU is on TG B then all inbound Local PSU calls will berepeated by the DVR locally and to the System on TG B. If the MSU mode is thenswitched to TG C then the Local PSU calls will be repeated on TG C etc.

TG Translation requires that TG Proxing is enabled.When TG proxing is enabled and the TG selected on the Local PSU is programmed inthe DVRS Translation Table, the DVRS will affiliate the Local PSU on the TG that isselected on the MSU.If TG Proxing is enabled but the Local PSU is on a TG that is not in the DVRS TGTranslation list then the DVRS will proxy any inbound / outbound calls.

Outbound call (System call) received on the currently selected MSU TG is repeated ‘asis’ i.e. without any translation. Therefore the Local PSUs need to be programmed withNormal Squelch (or NAC = F7E) in order to hear those calls.

Encryption Key Translation is not supported by DVRS.

Private CallsPrivate Calls (Local to Local PSU; Local to System PSU; System to Local PSU) aresupported on ‘DVRS Enabled’ PSUs only. Generic P25 PSU mode does not supportPrivate Calls via DVRS.

PSU Talk Permit Tones‘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 thecall is P25 Encrypted.As a programming option Local Mode tones can be generated when the System is busyand only Local repeat is available. Alternatively, the PSU user can get ‘System Busy’tones and be forced to wait for system grant (see ‘Digital System Setup Menu’ in theDVRS Programming section).Generic P25 PSU mode does not support Talk Permit Tones when operating through theDVRS.

In-Car MonitorIf In-Car Monitor is enabled in the DVR, the audio received from the Local PSUs will beheard in the MSU speaker if the TG selected on the PSU is the same as the TG selectedon the MSU.If the TG selected on the Local PSU is different from the one selected on the MSU (seeTalk Group Proxing), the voice received from the Local PSU will not be heard on theMSU speaker unless the Hook Switch (HUB) feature is enabled in the DVR and theMicrophone is currently Off Hook.Private Calls are never heard on the MSU speaker regardless of the Hook Switch (HUB)status unless the Private Call involves the particular MSU.

Trunking System Status IndicationThe following P25 Trunking system status indication is passed by the DVRS to the Local‘DVRS Enabled’ PSUs when the DVRS is in the System Mode:

Failsoft Out of Range Site Trunking

The above status indication is not available to Generic P25 PSUs when using the DVRS.The status indication is passed to the Local PSU every time the status changes. If thereis no change to the status, the DVRS send status indication to the Local PSUs at apreprogrammed time interval. The DVRS also sends a network status notification everytime a Local PSU is affiliated with the System via DVRS.

Local Mode IndicationWhen the DVRS is operating in the Local Mode, the PSU User can see “LOCAL ONLY”message displayed on the PSU screen.The above indication is only available on ‘DVRS Enabled’ PSUs and is not available toGeneric P25 PSUs when using the DVRS.

Radio Check / InhibitRadio Check and Radio Inhibit functions are passed through the DVRS to the Local PSUwhen the DVRS is in the SYSTEM or LOCAL mode. Those functions are available toboth ‘DVRS Enhanced’ and Generic P25 PSUs.

P25 Trunking OTARP25 Over The Air Rekeying (OTAR) is supported through the DVRS when the LocalPSUs are of the ‘DVRS Enabled’ type, the DVRS is in the SYSTEM mode and the MSUis 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.

PatchWhen several TGs are patched on the System side (using the trunking group-regroupingfunction), the DVRS ensures the patching is matched on the Local PSU side when‘DVRS Enabled’ PSUs are used, the DVRS is in the SYSTEM or LOCAL mode and theMSU is on a P25 Trunking TG.

8M083X01 Rev. 166881013Y39



Page 44 of 79

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

Dynamic RegroupingThe System Dispatcher can temporarily assign selected individual radios operating ondifferent TGs to operate on a new dedicated TG. The DVRS extends this functionality tothe ‘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 InterconnectPhone Interconnect is supported on Local P25 ‘DVRS Enabled’ PSU when the DVRS ison a full duplex P25 channel (digital or mixed mode) and the MSU is on a P25 Trunkedmode. Phone Interconnect requires the DVR to be in the System or Local mode.

Adaptive Power ControlThe DVRS sends P25 messages to the Local ‘DVRS Enabled’ PSUs to adjust theirtransmit power depending on the received signal strength and thereby to conserve thePSU battery. This feature is not supported on Generic P25 PSUs.

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

P25 EncryptionThe DVRS transparently passes the P25 encryption algorithms used by the subscriberand fixed network equipment. Even though the DVRS can be programmed to supportTG translation, it can not support encryption key translation.

Remote DVR Activation and Steering

Call Alert (Page) to DVRA P25 PSU may be programmed to send a Call Alert (Page) and preprogrammed NID toa specific DVRS and thereby remotely change:

DVRS Mode (from OFF or Local to System)DVR Status (Secondary / Primary)Selected TG / Channel on MSU

IMPORTANTRemote change of MSU TG has no effect on the operation of the rest of the PSUsin the area since the TG Proxing feature allows multiple TG operation. However, ifthe PSU remotely steers the MSU to a conventional channel, other PSU users willnot have trunking system access.

8M083X01 Rev. 166881013Y39



Page 45 of 79

The DVRS is addressed by sending a Call Alert (Page) with the specific programmedDVRS’ ID.

NOTEAll DVRS should have Unique IDs programmed in the Digital Mode Settings Menu if theremote control feature is to be used. If no DVRS ID is programmed, the DVR willassume the ID of the MSU currently interfaced to it.

The remote DVR status change will not be successful if there is another PermanentPrimary already present in the area (see Table 3).The following Table illustrates some typical remote Steering scenarios:

Table 4 Programming Example - Remote Steering

NOTE:F7E Enables the DVR / PSU to receive on any NID and TG ID.

The F7E setting ensures the DVR will receive when the PSU transmits different TX NIDs(4, 5, 6 in the above example).When a PSU User selects TG2 and sends a Call Alert / Page to the DVR (Using theunique DVR ID Number), the PSU will transmit with TX NID 5. The DVR will detect SteerNID 5 and switch the MSU to TG2.The DVR will be repeating the Call with TX NID 4, which is received by the PSU on anyof the steerable TGs.All of the above settings refer to DVR CH1 i.e. the PSU remotely steers TGs on thesame DVR channel. DVR channel steering is not recommended.

Dispatcher ControlDispatcher can send a Call Alert (Page) to a specific MSU, which in turn causes DVRmode change in the following order: OFF-SYS-LOC-OFF.It is recommended that remote mode change is disabled in the MSU and enabled in theDVR. If remote mode change is enabled in the MSU then the Call Alert Page featuremust be available to the Dispatcher only. The rest of the system subscriber equipmentmust not have the Call Alert (Page) feature enabled since paging a specific MSU

8M083X01 Rev. 166881013Y39



Page 47 of 79

interfaced to a DVR will toggle the DVR mode and may potentially cause loss of vitalcommunications.If the DVR is programmed with the ID of the dispatcher console then only Pages fromthis specific ID (or IDs) will cause DVRS mode change. If “Trunking Status Send”(System Setup 1 screen in Tweaker) is enabled, the DVRS will send back a modechange status to indicate its current mode (OFF, SYSTEM, LOCAL). Only theDispatcher Console can interpret those status messages if correctly programmed:

Status 1 = OFF modeStatus 2 = LOCAL modeStatus 3 = SYSTEM

The MSU should have the same unit ID in all DVRS Enabled Systems in order to ensurereliable mode change operation.

Dispatcher can not force a Non-Primary DVR to become a Primary and can not activatea DVR when a ‘VR Disabled’ mode is selected on the control head.

Emergency in Digital ModeWhen an affiliated Local PSU issues an emergency Alarm, the active Primary DVR willprocess the emergency to the system as follows:

If the ‘Portable ID Display’ box (in the DVR Emergency Mode Setup) is checked, theLocal PSU Unit ID will be displayed on the O5 / O3 / M5 of the current Primary DVRS.The PSU Unit ID will also appear on the display of the other Local PSUs if they areprogrammed accordingly.During Emergency Call, the Unit ID of the Local PSU, which has initiated the EmergencyCall, may be displayed on the System PSUs / MSUs if those are programmedaccordingly.The Local PSU ID during Emergency may also be displayed on the Dispatcher Console.

The DVR sends back an Emergency ACK to prevent the PSU from re-sending theEmergency either right after the DVR decodes the Emergency request (if the ‘SystemAcknowledge Type’ on the Mobile Radio Channel Settings menu is set to “VR Ack”)or after a System ACK has been received (if the ‘System Acknowledge Type’ on theMobile Radio Channel Settings menu is set to ‘Site Ack’ or ‘Console Ack’ ).

All Secondary DVRS in the area are monitoring the number of emergencies issued byLocal PSUs according to the ‘Attempts Timeout’ and ‘Attempts Counter’ settingsprogrammed in the DVRs Emergency Mode Setup. If the number of detected notserviced Emergency Attempts exceeds the counter, the Secondary DVRs will go throughPrimary / Secondary voting to select a new Primary to pass the emergency to theSystem.

If a DVRS is in the OFF Mode when it receives an Emergency from a Local PSU, theDVR will switch to System Mode after the ‘Attempts Counter’ is exceeded, affiliate thePSU and pass the Emergency to the System.

8M083X01 Rev. 166881013Y39



Page 48 of 79

The PSU Emergency attempts counter must be programmed to be equal to the DVRS‘Attempts Counter’ plus 3.

IMPORTANTHot Mic operation is only supported on DVRS Enabled PSUs that are loaded withfirmware R12.00.13 or later. Please check with Motorola for compatibility.

Emergency operation during TG TranslationEmergency operation is affected by TG Translation as follows:Inbound Emergency Alarm received by the DVRS on TG X will be translated andrepeated locally on all translated TG IDs that are selected on Local PSUs, which arecurrently affiliated with the DVRS. The Emergency Alarm is also translated to the ID ofthe TG selected on the MSU and forwarded to the System.Outbond Emergency Alarm received by the MSU on the MSU selected TG (TG Y) willbe translated and repeated to the Local PSUs on all translated TG IDs that are selectedon Local, affiliated with the DVRS PSUs.Inbound Emergency Call on TG X will be translated by the DVRS to the ID of the TGselected on the MSU and will be repeated locally on the translated TG.Outbound Emergency call received on TG Y selected on the MSU will be repeated bythe DVRS to the Local PSUs on TG Y.If Emergency Revert is programmed in the Local PSU then:If the revert TG is on the DVRS TG Translation list, then the Emergency will betranslated to the ID of the TG that is selected on the MSU.Emergency Alarm will be repeated locally on all Translation enabled TG IDs that areselected on Local, affiliated with the DVRS PSUs.If the revert TG is not in the DVRS TG Translation list then the emergency will beproxied and the inbound, outbound and local repeat will be on the new emergency revertTG.If the MSU (interfaced to the Master DVR) is placed in Emergency and programmed torevert in Emergency then a subsequent Local PSU emergency will also be translatedand declared on the MSU’s emergency revert TG.

Fireground (FG) SignalingIf Fireground (FG) signaling is enabled in the Local PSUs and on the selected full duplexDVRS channel, the DVR repeats locally the FG messages received form the Local PSUsto the FG terminal. If the Local PSUs are programmed for digital voice when transmittingFG signaling, a digital full duplex DVR channel with FG enabled must be selected.FG Emergency signaling received from the Local PSU can be either repeated locally,sent to the System or both (as programmed in the DVR).

Digital Outbound TakeoverWhen Digital Outbound Takeover is enabled in the DVR, a local PSU call is given higherpriority over an ongoing outbound call as described below.The DVR stops repeating the outbound call and starts repeating the LPSU call.The DVR tries to key up the MSU and if channel grant is received, the inbound call isrepeated to the system. Typically the MSU can only get channel grant and key up if theMSU is receiving on a different TG then the one selected on the LPSU. If the MSU is

8M083X01 Rev. 166881013Y39



Page 49 of 79

receiving a call on TG A and the LPSU tries to key up on the same TG A, the MSU willnot be able to key up (Trunking System programmed for Interrupt = Never).If TG Translation is enabled, the inbound LPSU call will always try to key up the MSU onits selected TG. The LPSU will be unable to interrupt the receiving MSU due to InterruptNever setting on the trunking system.The Digital Outbound Takeover operation depends on other system factors, such asDVRS programming (Call setup options on the Digital System Setup screen), trunkingsystem programming and PSU type (‘DVRS Enabled’ or ‘Generic P25’) and itsprogramming.For instance, if ‘Pass Deny to PSU’ is enabled (checked) in the DVR, then if the LPSUreceives a Deny, it will sound a deny tone, give up transmitting and will resume receivingof the outbound call. This example assumes that the PSU is ‘DVRS Enabled’. If aGeneric PSU is used, the PSU will transmit even when a deny is received and the DVRwill repeat locally the Generic PSU inbound call. The MSU will continue to receive theoutbound call from the system and the system audio will be heard on its speaker.Digital Outbound Takeover provides the ability for Regular and Emergency PSU calls tooverride FNE Outbound audio, however, PSU Patch calls do not have overridecapabilities.

Forced Analog DVR Mode - Operation and Programming OverviewForced Analog Mode is a hybrid mode in which the communications between the DVRSand the ‘DVRS Enhanced’ P25 PSU are digital, while the voice communications areforced to be analog. For more details, refer to Appendix 6 & 7.Forced analog mode is used when the Local PSUs are ‘DVRS Enhanced’ P25 while theMSU is programmed for Analog Conventional or 3600 Baud Trunking (analog or digital).When the MSU is on a Conventional or 3600 Baud Trunking (DVRS Enabled) channeland a Local PSU starts making an Inbound Call, the DVRS will force the PSU to transmitanalog voice in order to be able to transmit it over the selected Conventional Analog or3600 Baud Trunking MSU channel.

The DVRS must be on a DVR channel programmed for ‘F.Analog’ mode as described inthe ‘Repeater Channel Setup Menu’ section.

A DVRS in Forced Analog Mode does not work with Generic P25 PSUs.

IMPORTANTThe PSU and DVR PL/DPLs must be programmed to be properly matched. ThePSU must be programmed for mixed Receive in order to be able to program PL ona ‘DVRS Enabled’ channel.

8M083X01 Rev. 166881013Y39



Page 51 of 79

Analog DVR Mode - Operation and Programming OverviewThe Analog Mode supported Features are listed in Appendix 8, 9, 10 & 11.

DVR Channel Setup for Analog ModeTo enable Analog DVR operation on a specific DVR channel the Channel Type (in theRepeater Channel Setup Menu) must be set to Analog.The DVR Tx / Rx Frequencies as well as the Tx / Rx PL or DPL must be programmed tomatch the corresponding PSU settings.NOTE:Mixed DVR mode allows Analog DVR operation by switching between Digital andAnalog modes as described in the Mixed DVRS Mode section. The use of Mixed modefor Analog DVRS communications is not recommended since it requires special UserTraining. Mixed DVR mode should only be used when both analog and digital PSUs arerequired to operate on the same DVR channel.

Group CallsAn Analog Local PSU in DVRS mode can communicate with other Analog Local PSUsvia an active Primary DVRS if all units are using the same radio channel (full duplexonly) and using matching PL / DPLs.Inbound PSU calls will be repeated on the MSU side over the currently selected MSUTG / Channel.Outbound calls received by the MSU are repeated to the Local Analog PSUs.

Emergency in Analog ModeThe Emergency operation in Analog Mode is based on the type of signaling as selectedin the Emergency Mode Setup Menu. The recommended Analog Mode signaling type isMDC1200. Note that in addition to the DVR programming, MDC1200 signaling must alsobe enabled in the Local PSU personality.The following MDC1200 Emergency scenarios can be supported by DVRS ifprogrammed:MSU Emerg. Type (P25

or TII Trunking)Local PSU Emerg.

(MDC1200)Notes

Emergency Alarm Emergency AlarmEmergency Call -Emergency Call & Alarm Emergency Alarm

OREmergency Call & Alarm

To support Emergency Callfrom PSU, the DVR must beprogrammed to put MSU inEmergency – see EmergencyMode setup menu.

If the DVRS is in the OFF mode when the Local PSU sends the Emergency, the DVRSwill switch to the System Mode and process the Emergency after the EmergencyAttempts Counter expires and the Emergency is not processed by another Primary DVR.If MDC 1200 signaling is used, the Local PSU Emergency Alarm MDC ID will be passedthrough to the System provided the MDC ID is enabled (valid) on the System side.NOTE:MDC PTT ID pass-through is not supported by DVRS.

8M083X01 Rev. 166881013Y39



Page 52 of 79

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

Remote DVRS Activation via DTMFThe Local PSU may be programmed to remotely activate the DVR by switching it fromOFF or LOCAL to SYSTEM mode by sending a pre-programmed DTMF sequence (referto System Setup II for DVRS programming instructions related to this feature).The remote activation only works if the Local PSU and the DVR are set to operate on thesame radio channel and there is no other Primary / Permanent Primary DVR in the areaoperating on the same channel.The DVR can not be switched OFF remotely via DTMF.

P25 Encryption in Analog ModeIf the MSU is receiving a P25 Encrypted call while the DVRS is operating on AnalogChannel, the DVRS can be programmed to do one of the following:

Forward encrypted audio to the Local PSUs Forward Clear audio to the Local PSUs Send Warning Tones to the Local PSUs and no audio

Leading & Trailing TonesThe DVR can be programmed to send over-the-air Leading or Trailing tones to theLPSUs to indicate successful MSU key up / system access.If Leading Tones are enabled, the LPSU operation involves the following:

1. User does a quick PTT of LPSU so that MSU can request channel grant2. User releases the PTT for a moment and waits to hear the Leading tones.3. If the Leading tones indicate successful system access (channel grant), the

LPSU user PTTs again and talks.4. If the Leading tones indicate lack of channel grant, the LPSU user can try the call

again.Trailing tones are sent at the end of LPSU transmission and therefore do not requiredouble PTT.Both Leading and Trailing Tones are sent over-the-air (i.e. not generated in the PSU thatinitiates the call) therefore all LPSUs that are within the DVR range and switch to theDVR channel will hear the tones.

Mobile DetectorThis feature applies only to Analog Simplex DVR Operation when “Fallback in AnalogSimplex Mode” is Enabled (System Setup 1).The Mobile detector feature is used when the MSU operates on a VHF or UHFconventional half duplex channels without any base repeater.When mobile detector is enabled (in the DVR and MSU) and the non Priority DVR startsreceiving transmission from an LPSU, the DVR directs the MSU to ‘Listen Around’ andcheck if another MSU is handling the call. If no repeated transmission is detected fromanother MSU, the DVR will start repeating the inbound PSU call.The first few seconds of the LPSU transmission (inbound call) is always lost whilethe DVR is checking for Priority Repeat.

8M083X01 Rev. 166881013Y39



Page 53 of 79

Note: The Mobile Detector feature allows a non-Priority DVR to repeat inbound PSUcall when no Priority transmission is detected, however, the DVR does not become aPriority unit during Mobile Detector processing. The DVR can become a Priority unitonly as a result of the standard DVR Priority voting algorithm (exchanging of ‘HeartBeats’).

Mobile Mode SteeringThis feature allows a PSU User to remotely change the currently selected MSU mode bytransmitting with a pre-programmed PL/DPL. When the DVR decodes the PL/DPL itfinds the corresponding MSU mode in its look-up table and steers the MSU to the newmode. Depending on the programming, the MSU may either stay on the new mode or itmay revert after a preprogrammed timer expires to the originally selected MSU mode.The preprogrammed timer (‘Steering Hang Time’, System Setup 1) starts after theLPSU causing the steering keys off.

Steering and EmergencyIf steering is disabled on the current DVR channel, LPSU emergency is declared on thecurrently selected MSU channel (no steering).If steering is enabled on the current DVR channel, the LPSU emergency is declared onthe new (steered) MSU mode.When MSU is in emergency call state (‘Put MSU in Emergency on Analog DVRchannel’ is enabled), LPSU calls handling is defined by the ‘Steering in Emergency’programming for the specific DVR channel. If ‘Steering in Emergency’ is Disabled, theDVR repeats LPSU calls on the emergency channel (no steering occurs).If ‘Steering in Emergency’ is enabled, the DVR will steer and then key up the MSU. Inthis case the MSU will re-declare Emergency call on the new (steered to) channel.If ‘Put MSU in Emergency on Analog DVR channel’ is Disabled (LPSU and MSUprogrammed for Emergency Alarm only), an inbound LPSU call initiated while the MSUis waiting for emergency ACK, should terminate MSU emergency and steer the MSU tothe corresponding MSU mode/channel without re-declaring the emergency alarm on thenew MSU channel.

Mixed DVR ModeWhen a DVR Channel is programmed to operate in Mixed Mode, the DVRS can handlecalls from both P25 and Analog Local PSUs while the same DVR channel is selected onthe O5 / O3 / M5.When Mixed Mode is selected, the DVR can be toggled between Digital and AnalogMode as follows.The default DVRS mode is Digital i.e. the P25 modem is enabled by default. If a Callfrom a Local PSU is detected and the DVR does not decode a P25 Frame sync withinthe preprogrammed ‘P25 Frame Sync Detection Timer’, the DVR switches to AnalogMode and starts decoding Analog Mode signaling (such as DTMF, MDC1200 etc.). TheDVR enables the repeat of Analog signals to the Local Analog PSUs. After the LocalPSU keys off, the DVR stays in the Analog Mode for the duration of the preprogrammed‘VR Ch Mixed Mode Hold Timer’. Any Outbound calls which are received by the MSUprior to the above timer’s expiration will be repeated by the DVR as AnalogConventional. Once the ‘VR Ch Mixed Mode Hold Timer’ expires, the DVR returnsback to Digital Mode and any Outbound calls are repeated as digital.

8M083X01 Rev. 166881013Y39



Page 54 of 79

The DVRS operation in Mixed Mode is determined by the settings of the ‘P25 FrameSync Detection Timer’ and ‘VR Ch Mixed Mode Hold Timer’ as programmed in theDigital System Setup Menu Screen.Inbound calls (analog or digital) received by the DVR in Mixed Mode are repeated to theSystem on the currently selected MSU TG / Channel if proxing is disabled or are proxiedif proxing is enabled.

Primary / Secondary - Operation and Programming OverviewThe DVRS has a built-in simulcast prevention mechanism, which prevents more thenone DVRS to transmit on the same frequency, at the same time, in the same location.

NOTE:The algorithm is effective in stationary, same scene scenarios only. It can not be appliedto moving vehicles. Moving vehicles must have the DVRS switched OFF.

The DVRs are capable of communicating with each other and negotiating which DVR isa Primary i.e. elected to repeat and which DVRs are on Secondary for as long as thereis a Primary.The simulcast prevention algorithm has two phases:

Primary / Secondary PhaseBusy Lockout Phase

During the ‘Primary / Secondary’ Phase, the DVRs exchange P25 messages on their Rxfrequency. When a DVR is activated (switched to System or Local Mode), it sends aquery – “Is there a Primary?” If it receives a Primary (or Permanent Primary) ‘HeartBeat’, then the DVR assumes Secondary state. If no Primary Heart Beat is received, theDVR becomes the Primary and starts sending ‘Primary Heart Beats’ notifying otherDVRs of its status.The ‘Secondary’ DVRs monitor any DVR-related activity while in a Secondary mode andexecute Primary/Secondary checks periodically.The ‘Primary’ DVR services any communication requests in the area and‘communicates’ its status to the other DVRs periodically.The Busy Lockout phase serves as an added protection by forcing the Primary DVR notonly to periodically communicate with the other DVRs in the area (using its Rxfrequency) but also to check for any activity on its Tx frequency prior to every repeat.

In order to accommodate the dynamically changing “real life” environment i.e. DVRsarriving or leaving the scene at random time, DVR channel / mode changes, PermanentPrimary activation, Remote DVR steering etc., the Primary / Secondary algorithm hasseveral built-in layers, configurable in the DVR programmed personality.

The Transmit Power during DVRS-to-DVRS transmission is set by the ‘R-Tx Pwr’ field inthe Repeater Channel Setup Menu. Typically this field is selected to be 4-5dB lowerthen the ‘Tx Pwr’ setting.Before a Primary DVR sends out a ‘Heart Beat’, it checks for RF activity on its Rxfrequency to ensure the channel is free. If an RF signal is present and it exceeds theprogrammed ‘Rx RSSI Th’, the DVR will wait until the channel is free before it transmitsits ‘Heart Beat’.

8M083X01 Rev. 166881013Y39



Page 55 of 79

When a Secondary DVR stops receiving ‘Heart Beats’, the DVR will check for anyactivity on the Tx frequency to determine if the Primary DVR is busy transmitting.Note that the DVR can not transmit Heart Beats while it is busy repeating.If there is a transmission detected on the Tx frequency and it exceeds the programmed‘Tx RSSI Th’, the DVR will continue operating as a Secondary and continue waiting for a‘Primary Heart Beat’. If no activity is detected above the ‘Tx RSSI Th’ and 3 Heart Beatsare missed, the Secondary DVR will start negotiating becoming a Primary.

The ‘Heart Beat’ Interval (3-60 sec) is set by the ‘Heart Beat Interval’ field in the DigitalSystem Setup. The default Heart Beat Interval Value is 5 seconds.

When the ‘Enable BL For Voice Communication’ field (Digital System Setup Screen)is enabled (checked), the DVRS goes through an extra simulcast prevention check step.Prior to transmitting, a Primary DVR checks for any transmission (on the DVR Txfrequency) exceeding the programmed ‘Busy LC Th’ (see Repeater Channel SetupMenu). If no such RF transmission is detected on the Tx frequency, the Primary DVRstarts transmitting i.e. repeating. If Tx activity is detected, the DVR transmitsmomentarily then checks again if another DVR is still transmitting and either backs off (ifthe other DVR is still transmitting) or keys up if no transmission is present.

Disabling the DVR Primary / Secondary Processing from the Digital System SetupMenu is intended for test purposes or if the DVR is installed in a fixed location.

The ‘Permanent Master Status Enable’ field (in the Digital System Setup Menu) isdisabled by default and should be used only at remote, fixed DVR installations or duringtesting.

The ‘Rx RSSI Th’ field in the Repeater Channel Setup screen determines the Primary /Secondary range. If a DVR is receiving Primary Heart Beat from another DVR at a levellower then the programmed threshold, the DVR will ignore the Primary Heart Beats andwill negotiate becoming a Primary DVR as well.

The “Disable Master / Slave Processing” box is to be checked only during benchtesting. Master/ Slave processing should always be enabled during normal DVRoperation except during bench testing and in some fixed isolated installations (tunnels orin-building systems using common filtering / combiners).

If Legacy Mobexcom II Voting Compatibility mode is enabled in the DVR, its votingalgorithm is compatible with older style analog only Mobexcom II VRs. Enabling thisfeature allows seamless replacement of old style VRs with the new DVR by supportingthe deployment of both types of units in the same fleet during the transition period.

Using the Tweaker’s RSSI Setup ApplicationThe DVRS RSSI Setup screen is provided in order to assist the users with optimizingthe voting algorithm parameters by creating a typical real life scenario for DVRSoperation and running some automated DVRS tests as described below.

The RSSI setup screen is used to assist with the setup the following DVRS parameterson a per channel basis:

RSSI ON threshold Busy Lockout Threshold TX RSSI Threshold Rx RSSI Threshold

Setting up the RSSI ON rangeThe RSSI ON threshold defines the DVRS incident range since this is the minimumsignal level the DVR receiver needs to detect from the Local PSU in order to repeat itlocally and to the System.RSSI ON threshold is normally programmed to standard -110dBm. However, if the userwants to test the actual levels received from a portable radio located at the desiredcoverage area extreme then the ‘RSSI ON Level Test’ can be performed.To execute the test, the following steps are to be followed:

8M083X01 Rev. 166881013Y39



Page 57 of 79

1. PSU user is located at the edge of the desired coverage range and the PSU isswitched to the correct channel (matching the channel selected on the DVR).

2. Tweaker is running on the Master DVRS and Monitoring screen is open asshown above.

3. Select ‘System’ or ‘Local’ Mode in the ‘Operating Mode’ Field.4. Switch ‘Set Test Mode’ to ON.5. Press the ‘RSSI ON Level Test’ button.6. The PSU User will hear 3 short and 1 long beeps and he/she must immediately

press and hold the PTT for 10 seconds.7. The DVRS measures the received signal level and updates the RSSI ON

Threshold field. The check box against the parameter is checked to indicate testcompletion.

8. Enter desired Margin (min 6dB or higher recommended).9. Repeat the test for all required channels.10. Close the monitoring screen or proceed with the Voting algorithm tests as

described below.11. Review the ‘RSSI ON Threshold’ levels on the ‘Repeater Channel setup’ screen

and save to the DVRS and in a dpd file as required.

Setting up the Voting Parameters (Primary / Secondary Range)Those automated tests are used to calibrate the range between two Primary DVRS asfollows:

DVRS 1 – DVR with Tweaker running and RSSI Setup screen openDVRS 2 - DVR parked at the desired edge of DVRS 1 Primary Range i.e. if DVRS 2moves any farther it should also become a Primary.

1. Run Tweaker and open the RSSI Setup screen on DVRS 1.2. Deploy DVRS 2 and ensure both units are on the same channel.3. Select System or Local Mode in the Operating Mode Field.4. Switch “Set Test Mode” to ON.5. Type the ID of DVRS 2 in the Remote DVRS ID Box.6. Set Remote Test Mode to ON. Note that both DVRS will alternate ‘WARNING

2000’ and DVR channel / mode on the top line of the control head display.7. Press the ‘Busy Lock. Thresh. Test’ button and wait until the test is complete.8. Note the new levels in the ‘Busy Lock. Thresh.’ and ‘Tx RSSI Thresh.’ fields. The

two check boxes against those parameters will become checked to indicate testcompletion.

9. Press the ‘Master Range Test’ button and wait until the test is complete.10. Note the new level update in the ‘Rx. RSSI Thresh.’ field. The check box is

checked to indicate successful test completion.11. If any of the tests fails, please repeat the test.12. Enter required Margins and repeat the tests for all desired channels.13. Close the RSSI Setup screen and review the settings on the Repeater Channel

Setup screen.14. Save the data to the DVRS and dpd file as required.

Using the Tweaker Monitoring ScreenThe Tweaker’s Monitoring Screen is provided in order to assist the field technician withDVRS setup and troubleshooting.

The Monitoring screen provides real time indication of the RRSI level, SINAD, RFPower, PL detection etc.It must be noted that the Monitoring screen application is not intended to replace the useof properly calibrated test equipment in the field.

Troubleshooting

Software / Programming Related ProblemsMost of the DVRS Programming problems are caused by mismatched MSU, DVR andPortable Radio Templates.Note that any updates to the MSU or the PSU templates may require correspondingchanges to be made in the DVR template.

The following error message is displayed on the Control Head when the MSU and DVRfirmware versions are not compatible:

Hardware Related ProblemsIf the O5 / O3 / M5 Control Head displays alternating VR ERROR and Error Code (RCERROR XXXX or RF ERROR XXXX), turn the DVRS off and then back on. If it does notcorrect the condition, note the exact error code and contact Futurecom to obtain an RMAand further instructions.In case of insufficient DVR Tx Power or poor sensitivity, please verify that thefrequencies programmed in the DVR are within the filtering specifications as indicated onthe duplexer and in-band filtering labels.Ensure the DVR is only enabled on Mobile Radio Talk Groups using the frequency planfor the specific DVR Model.

Primary EEPROM Map corruptedWarning RC0400 displayed on the control head upon power up indicates that thePrimary EEPROM map of the DVR contains corrupted data. The DVR will still operateproperly from the backup EEPROM map. To fix the primary map, please use the latestTweaker to read the DVR. This will restore the Primary EEPROM Map.VR Error RC1000 displayed permanently indicates that both the Primary and BackupEEPROM maps are corrupted and the unit is not operation. Please contact Futurecomfor further instructions on how to troubleshoot the problem.

Firmware Upgrade.Some DVRS units which were originally shipped with older firmware may requireEEPROM map upgrade after re-flashing them with newer firmware. To upgrade theEEPROM, please follow the instructions shipped with the flash upgrade.

RC ERROR 4000 indicates that the DVR firmware has been updated but itsprogrammed personality has not. The DVR personality needs to be updated by readingthe unit with the Tweaker programming software in order to upgrade the EEPROM mapas described in the Firmware upgrade instructions provided by Futurecom.
