RF Energy Exposure Compliance, Awareness and
Control Information and Operational Instructions
ATTENTION!
Changes or modifications not expressly approved by Futurecom Systems Group,
ULC. could void the User’s authority to operate the equipment. To satisfy FCC/IC
RF exposure requirements for mobile transmitting devices, the minimum
separation distances specified in Table 1 should be maintained. To ensure
compliance, operations at closer than this distance is not allowed.
ATTENTION!
Futurecom requires the P25 VRX1000 operator to ensure FCC Requirements for
Radio Frequency Exposure are met. The minimum distance between all possible
personnel and the body of the VRX1000 equipped vehicle is specified in the “RF
Safety” booklet. Failure to observe the Maximum Permissible Exposure (MPE)
distance exclusion area around the antenna may expose persons within this area
to RF energy above the FCC exposure limit for bystanders (general population). It
is the responsibility of the repeater operator to ensure MPE limits are observed at
all times during repeater transmissions. The repeater operator must ensure at all
times that no person comes within MPE distance from the vehicle body.
USA Users: Do not use the VRX1000 in the frequency band 406.0 – 406.1MHz. This
frequency band is reserved for distress beacons.
ATTENTION!
This radio is intended for use in occupational / controlled conditions, where users
have full knowledge of their exposure and can exercise control over their
exposure to meet FCC limits. This radio device is NOT authorized for general
population, consumer, or any other use.
It is the responsibility of the VRX1000 Operator to ensure that Maximum
Permissible Exposure (MPE) limits are observed at all times during repeater
transmissions. If this vehicular repeater is used in combination with a separate
mobile radio transmitter, the Repeater operator must ensure at all times that no
person comes within the MPE distance from the vehicle body to ensure
compliance with the FCC’s/IC’s RF energy exposure limits for the general
population.
The minimum lateral distance between all possible personnel and the body of the
VRX1000 equipped vehicle must be as specified in Table 1.
Failure to observe the MPE distance exclusion area around the antenna may
expose persons within this area to RF energy above the FCC exposure limit for
bystanders (general population).

Introduction
The VRX1000 is a simplex radio coverage extender, which is interfaced to a compatible
remote mount Motorola Solutions Mobile Radio and enables Portable Subscriber Units
(PSU) to be used in areas where only Mobile Subscriber Unit (MSU) coverage is
available and PSU coverage is either intermittent or completely absent.
Installed in the trunk of a car, fire truck, armored vehicle, ambulance, the VRX1000
extends radio communications to the PSU users who are outside of the vehicle, inside a
nearby building or in any marginal portable radio coverage areas. The VRX1000 extends
voice (analog, P25 clear or P25 encrypted) communications and supports key trunking
system features. The VRX1000 can be configured to provide various advanced options
to the users.
Table 2 provides information on the VRX1000 infrastructure compatibility options.

Identifying Your VRX1000 Model
Frequency Band of Operation
Depending on the frequency band of operation of the APX Mobile Subscriber Unit (MSU)
and VRX1000, the VRX1000 models are classified as follows:
In-Band – when the MSU and VRX1000 operate in the same frequency band.
Cross-Band – when the MSU and VRX1000 operate in two different frequency
bands.
Cross-Band
Cross-Band VRX1000 models do not include any filters on the MSU side since the MSU
and VRX1000 are not intended to simultaneously operate in the same frequency band.
In single band MSU configurations the MSU and VRX1000 operate in different frequency
bands.
In dual band MSU configuration either the MSU & VRX1000 operate in 3 different
frequency bands or one of the MSU frequency bands is locked out when VRX operation
is enabled as shown on Figure 1.

In-Band
The in-band VRX1000 models are equipped with two sets of filters, which are required in
order to ensure interference-free operation when both the MSU and VRX1000 are
transmitting and receiving simultaneously in the same frequency band. The VRX1000
filter provides 40 dB isolation on the Mobile radio transmit / receive frequencies. The
filter installed at the output of the MSU is designed to provide 40 dB isolation on the
VRX1000 TX/RX Frequency Range.
IMPORTANT!
The above filter isolation must be complemented by 30dB minimum antenna
isolation (between the VRX1000 and Mobile Radio antennas) in order to ensure
interference-free operation. It is recommended that the MSU in-band antenna is
mounted on the roof top of the vehicle while the VRX antenna is mounted on the
trunk. Each VRX1000 is shipped equipped with custom filters tuned to the
specified frequency bands – note the frequency range specified on the filter
labels. Programming the VRX / MSU radio to operate on frequencies outside of the
original specified bands may result in intermittent or complete loss of
communications. Frequency changes may require filter retuning or replacement.
NOTE:
The VRX1000 and MSU require two or three (in the case of dual band MSU) separate
antennas.
IMPORTANT!
The In-Band filters connected to the APX MSU can handle up to 50 Watts MSU TX
power and have typical insertion loss of 1.5dB.

Band Locking
Two in-band sets of filters – one placed at the MSU Antenna port and another placed at
the VRX1000 Antenna port, are required when both the MSU and VRX1000 are
configured to operate in the same frequency band. The frequency specific in-band filters
are required in order to prevent interference when the VRX1000 is receiving & MSU is
transmitting and vice versa.
When the in-band filter is not present, the Band Lock feature must be enabled (by using
the Tweaker programming software) in order to prevent VRX1000 operation on MSU
channels that are explicitly using the same frequency band as the VRX1000. On MSU
channels where the frequency band is not explicitly known such as in multi-site trunking
systems, the MSU will be prevented from using frequencies in the same band while the
VRX1000 is active (i.e. in SYSTEM or LOCAL mode). In this case the MSU will no
longer allow roaming to sites using the locked out band. If the MSU is currently on a
trunking site that uses the locked out band, the MSU will roam to another site. If no other
sites are available, the MSU will enter Out Of Range state. When the VRX1000 is
inactive (OFF mode), the MSU frequency band is unlocked.
In the case of a single band MSU (such as the APX4500 and APX6500), in-band
VRX1000 applications always require in-band filters and the Band Locking feature must
be disabled.
For MSU conventional channels where the band is known and fixed, the VRX1000
restricts access to channels using the locked out frequency band.
If Band locking is enabled in the VRX1000 and SCAN is enabled in the MSU, the MSU
will skip over any channels in the scan list that are configured to operate in the same
frequency band as the VRX1000.
IMPORTANT!
A 700MHz VRX1000 interfaced to APX MSU operating on 800MHz as well as an
800MHz VRX1000 interfaced to APX MSU operating on 700MHz are considered InBand applications and either In-Band filters must be provided or band locking
must be enabled (if the MSU is dual band and VRX operation can be supported on
the non 700/800MHz band).
The above is also valid for any of the UHF Bands – if the MSU operates on any of
the UHF ranges, an UHF VRX interfaced to it will require in-band filters to be
installed or band locking to be enabled.

Powering up the VRX1000
The VRX1000 powers up together with the MSU. The power up mode and channel are
programmable. Depending on the programmed personality, the VRX1000 can power up
in one of the following states:
VRX1000 Disabled mode, last selected VRX1000 channel
OFF mode
SYSTEM mode, last selected VRX1000 channel
SYSTEM mode, preprogrammed VRX1000 channel
LOCAL mode, last selected VRX1000 channel
LOCAL mode, preprogrammed VRX1000 channel
If the VRX1000 powers up on a ‘strapped’ mobile radio channel, the VRX1000
will be steered according to the Talk Group selected on the MSU. The steering
may involve both VRX1000 channel and mode change.
Turning ON the VRX1000
When the MSU is powered up, the VRX1000 can be activated by one or more of the
methods described in the following section.
The VRX1000 is ON when SYSTEM (or optionally LOCAL) mode of operation is
selected.
The VRX1000 is OFF when OFF mode is selected.
The VRX1000 is disabled when a “VRX1000 Disabled” Mode / Channel is
selected on the APX MSU or if the currently selected VRX1000 and MSU modes
are incompatible (such as TDMA MSU mode and P25 Digital VRX1000 channel).
NOTE:
The VRX1000 can only be activated when a compatible “VRX1000 Enabled” mode /
channel is selected on the APX MSU.
Activating the VRX1000 via the Control Head
Ensure the MSU is powered up and a VRX1000 Enabled TG / channel is selected on the
control head.
To activate the VRX1000:
Press the DVRS menu item to enter the ‘DVR/VRX1000 Control Mode’.
Once in the ‘DVR/VRX1000 Control Mode’ screen, press the MODE button to
toggle the available VRX1000 modes until the desired mode is selected.
Press the SEL button or wait the preprogrammed time until the ‘DVR/VRX1000
control Mode’ screen times out. The last selected VRX1000 mode becomes
effective.
Long press of the DVRS menu item can be programmed to turn the VRX1000
ON/OFF.
Pressing the DVRS button allows the user to enter the ‘DVR / VRX1000 Control Mode’
and to select the desired VRX1000 mode and channel.

Automatic VRX1000 Activation (AVRA)
The VRX1000 can be activated automatically (switched from OFF or LOCAL to SYSTEM
Mode) if one of the VIP inputs on the MSU control head is wired to the desired trigger
source – portable charger switch or door switch or custom manual switch.
When AVRA is enabled in the VRX1000, the user still has the option of manually
changing the VRX1000 mode from the MSU control head or remotely.
The AVRA feature depends on the VRX1000 programming as shown below:

Remote Activation of the VRX1000
Via Call Alert (Page) to VRX1000
NOTE:
This feature requires the use of a P25 PSU and implies Digital or Forced Analog
VRX1000 mode of operation.
To remotely activate a VRX1000, the PSU user can send a Call Alert (Page) with the ID
of the specific VRX1000.
Upon receipt of a Call Alert (Page) from the PSU the VRX1000 will:
Switch from OFF or LOCAL mode to SYSTEM mode (unless it is already in the
SYSTEM mode). If the selected VRX1000 / MSU channel is programmed as
LOCAL only, the VRX1000 will switch from OFF to LOCAL mode.
Switch to Primary status and force any other Primary VRX1000 to become a
Secondary unless there is a Permanent Primary (on the same VRX1000
channel) already present in the same area.
Force the MSU to revert to a TG selected on the PSU (if programmed).
Via PSU Emergency Alarm
The VRX1000 switches from OFF to SYSTEM mode after a programmable number of
Emergency Alarm attempts sent by a PSU are successfully received by the VRX1000
and are not serviced by another (Primary) VRX1000.
Via PSU DTMF Tones
To remotely activate a VRX1000 (analog mode), the PSU user can send a
preprogrammed DTMF sequence, which can be received by VRX1000 in the PSU radio
coverage area.
Upon receipt of the preprogrammed DTMF sequence from the PSU the VRX1000 will:
Switch from OFF or LOCAL mode to SYSTEM mode.
Switch to Primary status unless there is already a Primary / Permanent Primary
VRX1000 (on the same VRX1000 channel) already present in the same area.
DTMF activation is supported on analog or mixed mode VRX1000 channels only.

Via System / Dispatcher Call Alert Page to MSU
Dispatcher can send a Call Alert (Page) to a specific MSU ID, which in turn causes
VRX1000 mode change in the following order: OFF-SYS-LOC-OFF.
The MSU can be programmed to support one of the following configurations:
a. Call Alert / Remote Activation Disabled – the MSU does not respond to any Call
Alert requests
b. Call Alert Enabled – the MSU responds to Call Alerts addressed to its ID and
does NOT initiate VRX1000 mode change
c. Remote Activation Enabled – the MSU will acknowledge Call Alerts addressed to
its ID and will initiate VRX1000 mode change provided the source ID of the Call
Alert is programmed in the “VRX1000 Remote Activation IDs” table.
If “Generate Status on DVR Mode Change” is enabled for a given VRX1000 Profile (in
the APX MSU) , the MSU will send back a mode change status to indicate the current
VRX1000 mode (OFF, SYSTEM, LOCAL). Only the dispatcher console can interpret
those status messages:
Dispatcher can’t force a Non-Primary VRX1000 to become a Primary and can’t activate
a VRX1000 when a ‘VR Disabled’ mode is selected on the control head.

Automatic VRX1000 Deactivation
AVRA
If the VRX1000 is in the SYSTEM or LOCAL Mode and the AVRA VIP input is deasserted, the VRX1000 can be programmed to automatically switch to OFF Mode as
described in Table 5. If the VRX1000 is in the OFF Mode, de-asserting the AVRA VIP
will not result in any change. The method of de-asserting the AVRA VIP depends on the
actual installed AVRA trigger. For example, if the selected AVRA trigger is the Portable
Charger Switch, de-asserting the AVRA VIP input is equivalent to placing the PSU back
in the charger.
Inactivity Timer
If programmed, the VRX1000 can switch automatically to OFF mode upon expiration of
its Inactivity Timer (programmable from 0 to 180 minutes). The timer is restarted every
time the VRX1000 detects PSU activity.

‘DVRS/VRX1000 Enabled’ Mobile Radio TGs / Channels
VRX1000 operation may be enabled (by the VRX1000 and MSU programming) on
selected mobile radio Talk Groups / channels and disabled on others.
When the user selects a DVRS/ VRX1000 Enabled TG / channel on the MSU control
head, the VRX1000 operation is enabled in the following manner:
The VRX1000 automatically enters the pre-programmed VRX1000
mode/channel associated (‘Strapped’) with the selected MSU TG / channel if
VRX1000 strapping is programmed in the VRX1000.
OR
The user may change the VRX1000 mode / channel (if ‘strapping’ is not
enabled) by pressing the assigned DVRS/VRX1000 button and entering the
‘DVR/ VRX1000 control mode’.
The VRX1000 can be activated and used to repeat messages between the
system users of the TG/channel selected on the MSU and the PSU users on the
selected VRX1000 channel.
If enabled in the VRX1000 personality, ‘VRX1000 Enabled’ tones will be heard
every few seconds (5-255 sec. programmable) in the MSU speaker, regardless
of the Primary / Secondary status.
‘DVRS/VRX1000 Disabled’ Mobile Radio TGs / Channels
VRX1000 operation may be enabled on selected mobile radio Talk Groups / channels
and disabled on others.
When the user selects a “DVRS/VRX1000 Disabled” TG / channel on the control head:
Pressing the DVRS/VRX1000 button results in a VRX1000 Invalid Option Tone
(single low-pitched tone).
VRX1000 operation is prohibited i.e. all VRX1000 functions are disabled.
Call Alert Page from the local PSU, sent on the last used VRX1000 channel, can
steer the MSU to a ‘VR Enabled’ mode if programmed accordingly.

In Car Monitor (ICM)
The ICM feature allows the MSU to monitor PSU Voice traffic and is configurable in the
MSU codeplug as follows:
ICM is enabled / disabled globally in the MSU via the ‘ICM Allowed’ Field
If ‘ICM Allowed’ is programmed in the MSU then ICM operation is further
configured on a per MSU channel basis via the ‘ICM Allowed’ codeplug field.
ICM functionality is further configured to be triggered by either Hang Up Box
(HUB) on / off transitions OR via menu item / button on the MSU control head or
keypad microphone.
When ICM functionality is configured to be triggered via HUB on/off then ‘ICM Selected’
operation takes place when the MSU microphone is placed on HUB, ‘ICM All’ operation
will take place when the MSU microphone is taken off HUB.
For details on how to program the ICM functionality and options in the MSU, please refer
to the corresponding Motorola Solutions Documentation.
When the MSU is operating on a Trunking FNE with ICM enabled the following
configurations are available:
‘ICM Selected’ – the MSU speaker unmutes to PSU audio matching its selected
TG ID (digital VRX channel) or all qualified analog PSU audio (analog VRX
channel).
‘ICM All’ – the MSU speaker unmutes to all PSU audio regardless of the TG ID
(digital VRX channel) or all analog PSU audio (analog VRX channel).
When the MSU is operating on a Conventional FNE with ICM enabled the following
configurations are available:
‘ICM Selected’ and MSU configured for Selective Squelch – the MSU speaker
will unmute only to PSU audio matching its selected TG (digital VRX channels) or
qualified analog audio (analog VRX channels)
‘ICM Selected’ and MSU configured for Normal Squelch – the MSU speaker will
unmute to any PSU TG audio (digital VRX channels) or qualified analog PSU
audio (analog VRX channels).
‘ICM All’ – the MSU speaker unmutes to all PSU audio

User’s Guide
Primary / Secondary Operation Basics
The VRX1000 has a built-in simulcast prevention mechanism, which prevents more than
one VRX1000 to transmit on the same frequency, at the same time, in the same
location.
NOTE:
The algorithm is intended to operate in stationary, same scene scenarios only. It cannot
be applied to moving vehicles. Moving vehicles must either have the VRX1000
switched OFF or ‘VR Disabled’ MSU mode selected.
The VRX1000 units are capable of communicating with each other and negotiating
which VRX1000 is a Primary, i.e. elected to transmit, and which VRX1000s are
Secondary for as long as there is a Primary.
The simulcast prevention algorithm has two phases:
Primary / Secondary Phase
Busy Lockout Phase
During the ‘Primary / Secondary’ phase, the VRX1000 units exchange P25 messages.
When a VRX1000 is activated (switched to System or Local mode), it sends a query –
“Is there a Primary?” If it receives a Primary (or Permanent Primary) ‘Heart Beat’, then
the VRX1000 assumes Secondary state. If no Primary Heart Beat is received, the
VRX1000 becomes the Primary and starts sending ‘Primary Heart Beats’ notifying other
VRX1000s of its status.
The ‘Secondary’ VRX1000s monitor any VRX1000-related activity while in a Standby
mode and execute Primary/Secondary checks periodically.
The ‘Primary’ VRX1000 services any communication requests in the area and
‘communicates’ its status to the other VRX1000s periodically.
The Busy Lockout phase serves as an added protection by forcing the Primary VRX1000
to check for any activity on its Tx frequency prior to transmitting.
The Primary / Secondary Status of a VRX1000 is re-evaluated every time one of the
following takes place:
Change of VRX1000 channel frequency
Change of VRX1000 mode
Remote activation of another VRX1000

Permanent Primary Activation
If programmed, a VRX1000 can be forced to be a Permanent Primary from the MSU CH.
NOTE:
If another Permanent Primary is already present, the newly activated Permanent Primary
VRX1000 will force the “old” Permanent Primary to assume Permanent Primary ‘On
Standby’ Status. If the Permanent Primary leaves the scene, the Permanent Primary
‘On Standby’ takes over. If several users try to simultaneously activate several
VRX1000 units as Permanent Primaries, the VRX1000s will go through voting to ensure
only one Permanent Primary is selected and all other VRX1000s are forced to become
Permanent Primary ‘On Standby’.
Permanent Primary Deactivation
The Permanent Primary status of a VRX1000 can be switched off from the MSU CH.
Legacy Mobexcom II Voting Compatibility Mode
The voting compatibility mode is applicable to analog VRX1000 mode only. If Legacy
Mobexcom II Voting Compatibility mode is enabled in the VRX1000, its voting algorithm
is compatible with the legacy analog only Mobexcom II VRs. Enabling this feature allows
seamless replacement of old style VRs with the new VRX1000 by supporting the
deployment of both types of units in the same fleet during the transition period.

Selecting VRX1000 Mode
When a ‘DVRS/VRX Enabled’ TG / channel is selected on the MSU, the user may enter
the ‘DVRS/VRX Control Mode’ by pressing the DVRS button on the control head and
change the VRX1000 mode / channel / status as described below:
Selecting VRX1000 Mode from the Control Head
To change the VRX1000 mode:
Press the DVRS button and observe the MSU enter the ‘DVR/VRX Control
Mode’.
Press the MODE button to toggle the VRX1000 mode until the desired selection
appears on the top line of the control mode display.
Once the desired mode is displayed press the SEL button or simple wait for the
control mode to timeout (the last selected VRX1000 Mode is in effect).
Strapped VRX1000 Mode
The VRX1000 mode and channel may be programmed to be ‘Strapped’ to the specific
MSU TG/Channel.
In this case, selecting a specific MSU TG / channel on the control head would
automatically force the VRX1000 to revert to a pre-programmed mode and/or channel.
For example, selecting a VRX1000 Enabled TG named ‘DISPATCH’ on the MSU may
automatically force the VRX1000 to switch to Channel 1, SYSTEM Mode. If enabled in
the specific VRX1000 personality programming, the VRX1000 user can still toggle the
VRX1000 mode by pressing the DVRS button and entering the ‘DVR/VRX Control
Mode’. If mode change by the user is prohibited in the specific VRX1000 personality, the
user can only select between the ‘Strapped’ (either LOCAL or SYSTEM) and OFF
VRX1000 modes from the ‘DV/VRXR Control Mode’ menu.
Selecting VRX1000 Channel
When a ‘DVRS Enabled’ TG / Channel is selected on the MSU, the user may enter the
‘DVRS/VRX Control Mode’ by pressing the assigned DVRS button on the MSU control
head and then change the VRX1000 mode / channel / status as described below:

Supported MSU Scan Types
The MSU Scan feature is allowed while the VRX1000 is active (System or Local Mode) if
the MSU Scan type is configured as one of the following:
Conventional Scan
Mixed Conventional Voting Scan
Legacy Voting Scan
When the VRX1000 is activated (System or Local Mode), the MSU scan feature is NOT
allowed if the MSU Scan type is configured in the selected MSU personality as one of
the following:
Multi-System Scan
Priority Monitor Scan
VRX1000 Enabled / Disabled Rules while MSU Scan is enabled
The Selected VRX1000 channel settings are used across all MSU scan channels except
when the VRX1000 operation is Disabled for the given MSU channel.
If the VRX1000 selected channel is Digital and the MSU scans to an analog channel, the
VRX1000 will become temporarily disabled.
If the Selected MSU channel is programmed as VRX1000 Disabled, the VRX1000
operation will remain disabled even if the MSU scans to a channel which is VRX1000
Enabled.
The VRX1000 will become temporarily disabled if the MSU lands on a channel that is
programmed as VRX1000 Disabled. In this scenario the VRX1000 will not handle
Outbound calls received by the MSU but will still repeat Inbound PSU calls by reverting
the MSU to its selected channel.
Outbound Calls (received by MSU from the FNE) with MSU Scan Enabled
If the MSU is configured to only unmute to a specific TG ID or NAC, only the audio
containing the specified TG ID or NAC will be proxied by the VRX1000 to the PSU.
Individual call signaling (Page, Call Alert, Message, Radio inhibit etc) originating from a
secondary (not the MSU selected) channel is not proxied by the VRX1000 to the PSU.
Emergency Alarm / Call originating from a secondary channel are supported through the
VRX1000.
Inbound Calls (received by VRX1000 from PSU) with MSU Scan Enabled
MSU Talkback and Designated TX are not supported when a PSU makes a call through
the VRX1000 while the MSU has SCAN enabled. The MSU always moves back from the
landed to the selected channel when the PSU initiates a call through the VRX1000.
Talkback and Designated TX are supported only for MSU initiated calls.

The P25 Digital mode assumes the following:
APX MSU Programmed for VRX1000 Operation
P25 FDMA only mode is selected on the MSU.
P25 PSU programmed for VRX1000 operation (Local PSU).
VRX1000 Enabled mode selected on the Local PSU.
VRX1000 channel programmed as Digital or Mixed or Forced Analog Mode of
Operation.
NOTE:
The Local PSU notation throughout this chapter refers to a P25 PSU which is used to
communicate with / through the VRX1000.
‘VRX/DVRS Enabled’ type Local PSU refers to the models described in Table 7 when
programmed for VRX1000 operation.
Some of the Digital mode features described are only available in P25 ‘VRX/DVRS
Enabled’ type PSUs and not available in Generic P25 PSUs (refer to Table 7). The use
of ‘VRX/DVRS Enabled’ PSUs and associated features through the VRX1000 require
that the VRX has Option TT05953AA.
A System PSU refers to a P25 PSU which has a P25 Mode (Trunking or Conventional)
selected and communicates directly with the P25 Trunking or Conventional System, i.e.
without a VRX1000.
In cross-band applications, the Local PSUs operate in different frequency band from the
system infrastructure, i.e. from the System PSUs.
The same PSU may be used as System and / or Local PSU depending on its currently
selected mode.

The Local PSU User can change the selected ‘DVRS/VRX Enabled’ TG and seamlessly
talk to the corresponding TG users through the VRX1000. The MSU can be on any
‘DVRS/VRX Enabled’ 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 can talk to Local TG1 users (in Talk Around) as well as System TG1 users via the
VRX1000 i.e. the MSU will be transmitting on TG1. If the MSU microphone is PTT-ed,
the MSU will transmit 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 the VRX1000 to the
Local PSUs.
If Proxing is Disabled then the Local PSU and the MSU must have the same TG
selected in order to enable Local PSU affiliation and communications.
Talk Group Translation
When TG translation is enabled in the VRX1000 for a specific PSU TG ID, then any call
that is received by the VRX1000 from the Local PSU with this TG ID will be translated to
the ID of the 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 programmed in the VRX1000 TG
Translation list, the PSU call will always be translated by the VRX1000 to the TG ID
currently selected on the MSU control head. For instance, if the Local PSU is on TG A,
which is programmed in the VRX1000 TG Translation list and the MSU is on TG B then
all inbound Local PSU calls will be repeated by the VRX1000 to the FNE on TG B. If the
MSU mode is then switched to TG C then the Local PSU calls will be repeated on TG C
to the FNE.
Generic (non-DVRS/VRX Enabled) Conventional P25 PSUs that are not enabled for
talkgroup operation will, by default, use TG ID 1 when transmitting. If TG ID 1 is added to
the VRX1000 Translation table then PSUs transmitting TG ID 1 will be translated to the
TG selected on the MSU.
IMPORTANT!
TG Translation requires that TG Proxing is enabled.
When TG proxing is enabled and the TG selected on the Local PSU is programmed in
the VRX1000 Translation Table, the VRX1000 will affiliate the Local PSU on the TG that
is selected on the MSU. If TG Proxing is enabled but the Local PSU is on a TG that is
not in the VRX1000 TG Translation list then the VRX1000 will proxy any inbound /
outbound calls on the PSU TG ID. Outbound call (system originated call) received on the
February 2016 Page 50 of 92
8A087X02 R3
VRX1000
User’s Guide
currently selected MSU TG is repeated ‘as is’ i.e. without any translation. Therefore the
Local PSUs need to be programmed with Normal Squelch (or NID = F7E) in order to
hear those calls.
IMPORTANT!
Encryption Key Translation is not supported by the VRX1000.
Private Calls
Private Calls (Local to System PSU; System to Local PSU) are supported on
‘DVRS/VRX Enabled’ PSUs only.
NOTE:
Inbound and Outbound Private Calls are not supported on ‘Generic P25’ PSUs or if the
VRX1000 does not have Option TT05953AA Installed.
PSU Talk Permit Tones
‘Go Ahead’ tones are generated in the ‘DVRS/VRX Enabled’ PSUs. Different tones are
generated to indicate if the VRX1000 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 mode 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 the DVRS Programming section). Talk Permit Tones are NOT supported
when using Generic P25 PSU mode.
NOTE:
PSU Talk Permit Tones are not supported on ‘Generic P25’ PSUs or if the VRX1000
does not have Option TT05953AA Installed.

Status Broadcast
If enabled in the VRX1000 (“Network Status Reporting Interval”, Digital System setup
screen), the VRX1000 transmits status broadcasts that can be received only by P25
“DVRS/VRX Enabled” PSUs:
FNE Out of Range
VRX1000 Local only status
Site Trunking
IV&D Data Enabled / Disabled status
NOTE:
Only a Primary VRX1000 can transmit Status Broadcasts.
The above status indication is not available to Generic P25 PSUs or if the VRX1000
does NOT have Option VRX8003 installed. The status indication is passed to the Local
PSU every time the status changes. If there is no change to the status, the VRX1000
sends status indication to the Local PSUs at a preprogrammed time interval. The
VRX1000 also sends a network status notification every time a Local PSU is affiliated
with the FNE via VRX1000. If the FNE enters Failsoft mode, the MSU proxies the
Failsoft message (if Failsoft is enabled in the MSU), the VRX1000 stops sending Status
Broadcast to the Local “DVRS/VRX Enabled” PSUs and periodically transmits Failsoft
message instead.
NOTE:
Status Broadcast is not supported on ‘Generic P25’ PSUs or if the VRX1000 does not
have Option TT05953AA Installed.
Local Mode Indication
When the VRX1000 is operating in the LOCAL mode, the “DVRS/VRX Enabled” PSU
User can see “LOCAL ONLY” message displayed on the PSU screen.
The above indication is only available on ‘DVRS/VRX Enabled’ P25 PSUs.
NOTE:
Local Mode Indication is not supported on ‘Generic P25’ PSUs or if the VRX1000 does
not have Option TT05953AA Installed.
Radio Check / Inhibit
Radio Check and Radio Inhibit functions are passed through the VRX1000 to the Local
PSU when the VRX1000 is in the SYSTEM or LOCAL mode. Those functions are
available to both ‘DVRS/VRX Enabled’ and Generic P25 PSUs when the MSU is
operating on a P25 Trunked or P25 Conventional Mode. If the MSU gets radio inhibited,
the VRX1000 switches to ‘VR Disabled’ mode of operation.
P25 Trunking OTAR
P25 Over The Air Rekeying (OTAR) is supported through the VRX1000 when the Local
PSUs are of the ‘DVRS/VRX Enabled’ type, the VRX1000 is in the SYSTEM mode and
February 2016 Page 52 of 92
8A087X02 R3
VRX1000
User’s Guide
the MSU is on a P25 Trunking mode. OTAR is not supported on a P25 conventional
MSU channels.
NOTE:
P25 Trunked OTAR is not supported on ‘Generic P25’ PSUs or if the VRX1000 does not
have Options TT05952AA and TT05953AA installed.
Patch
When several TGs are patched on the system side (using the trunking group-regrouping
function), the VRX1000 ensures the patching is matched on the local PSU side when
‘DVRS/VRX1000 Enabled’ PSUs are used, the VRX1000 is in the SYSTEM or LOCAL
mode and the MSU is on a P25 Trunking TG.
IMPORTANT!
System design must ensure that PSU TGs that are programmed for TG Translation
are outside of the range of talkgroups used on the trunking system.
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).
NOTE:
Patch is not supported on ‘Generic P25’ PSUs or if the VRX1000 does not have Option
TT05953AA Installed.

Dynamic Regrouping
The Dynamic Regrouping feature allows a dispatcher to remotely redirect subscribers to
operate on a designated TG without any intervention from the subscriber unit operator.
This is done by remotely assigning a new TG for the subscriber to operate on. When the
subscriber receives the request, it automatically switches to the assigned zone /
channel. The VRX1000 extends this functionality to the ‘DVRS/VRX Enabled’ Local
PSUs when the VRX1000 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 or ungrouped) and Selector Lock / Unlock (disabling / enabling the
zone/channel selection functionality while a PSU is dynamically regrouped) are not
presently supported via the VRX1000.
NOTE:
Dynamic Regrouping is not supported on ‘Generic P25’ PSUs or if the VRX1000 does
not have Option TT05953AA Installed.
Phone Interconnect
Phone Interconnect is NOT supported on the VRX1000.
Adaptive Power Control
The VRX1000 can be programmed to send P25 messages to the Local ‘DVRS/VRX
Enabled’ PSUs to adjust their transmit power depending on the received signal strength
from the VRX1000 and thereby to conserve the PSU battery. Enabling this feature is
NOT recommended in applications where more than one PSU are typically used with a
single VRX since it will affect the PSU-to-PSU communications.
This feature is not supported on Generic P25 PSUs.
NOTE:
Adaptive Power Control is supported on both ‘Generic P25’ XTS/APX PSUs as well as
on “DVRS/VRX Enabled” PSUs.
Digital Audio Buffering
Audio buffering is supported by the VRX1000 in order to eliminate loss of messages /
parts of messages due to the inherent delays associated with acquiring system access.
The Digital Audio Buffer in the VRX1000 is programmable up to 1800ms.

P25 Encryption
The VRX1000 transparently passes the P25 encryption algorithms used by the
subscriber and fixed network equipment. Even though the VRX1000 can be
programmed to support TG translation, it cannot support encryption key translation.
When the VRX1000 is on a P25 Digital channel, inbound digital audio from a Local PSU
is handled according to the following table:
Table 22 Inbound P25 Encryption Rules
While the VRX1000 is on a Digital channel, outbound digital audio originating from the
FNE is handled according to the following table:
Table 23 Outbound P25 Encryption Rules
While the VRX1000 is on a Digital channel, outbound digital audio originating from the
MSU is handled according to the following table:
Table 24 MSU MIC PTT P25 Encryption Rules
The MSU interfaced to the VRX1000 will unmute to Inbound or Outbound Encrypted P25
calls ONLY if the MSU contains the key used for encryption in its Encryption Key List.
NOTE:
P25 Encryption support requires Option TT05952AA to be installed in the VRX1000.

Remote VRX1000 Activation and Steering by PSU Call Alert
(Page)
A P25 PSU may be programmed to send a Call Alert (Page) and preprogrammed
Network ID (NID) to a specific VRX1000 and thereby remotely change:
VRX1000 Mode (from OFF or Local to System)
VRX1000 Status (Secondary / Primary)
Selected TG / Channel on MSU
NOTE:
Remote change of MSU Mode has no effect on the operation of the rest of the PSUs in
the area since the TG Proxing feature allows multiple TG operation. This applies to
Mode change within the same system, and when TG Translation is not enabled
The VRX1000 is addressed by sending a call alert (page) with the specific programmed
VRX1000 ID.
NOTE:
All VRX1000 should have unique IDs programmed in the digital mode settings menu if
the remote control feature is to be used. If no VRX1000 ID is programmed, the VRX1000
will assume the ID of the MSU currently interfaced to it. Remote activation and steering
are supported when the MSU ID = VRX1000 ID.
The remote VRX1000 status change will not be successful if there is another Permanent
Primary already present in the area (see Table 25).

Emergency in Digital Mode
The ‘DVRS/VRX Enabled’ P25 PSU can be programmed to block the launch of the
Emergency feature if the P25 Trunking system is in failsoft mode (when ‘Emergency
Blocked in Failsoft’ is enabled). The ‘DVRS/VRX Enabled’ P25 PSU can be programmed
to use the programmed ‘Revert Talkgroup’ while in Emergency and when on the
Dynamic Talkgroup channel without an assigned dynamic working group.
Emergency Alarm
When an affiliated Local PSU issues an Emergency Alarm, the active Primary VRX1000
will process the Emergency to the system as follows:
If the ‘Portable ID Display’ box (in the VRX1000 Emergency Mode Setup) is
checked, the local PSU unit ID will be displayed on the MSU control head of the
current Primary VRX1000.
The PSU unit ID will also appear on the display of the other local PSUs if they
are programmed accordingly.
During Emergency Call, the unit ID of the local PSU, which has initiated the
Emergency Call, may be displayed on the system PSUs / MSUs if those are
programmed accordingly.
The local PSU ID during Emergency may also be displayed on the dispatcher
console.
The VRX1000 sends back an Emergency ACK to prevent the PSU from re-
sending the Emergency either right after the VRX1000 decodes the Emergency
request (if the ‘System Acknowledge Type’ on the Mobile Radio Channel
Settings menu is set to “VR Ack”) or after FNE ACK has been received (if the
‘System Acknowledge Type’ on the Mobile Radio Channel Settings menu is
set to ‘Site Ack’ or ‘Console Ack’ ).
All Secondary VRX1000 in the area are monitoring the number of emergencies
issued by local PSUs according to the ‘Attempts Timeout’ and ‘Attempts
Counter’ settings programmed in the VRX1000s Emergency Mode Setup. If the
number of detected but not serviced Emergency Attempts exceeds the counter,
the Secondary VRX1000s will go through Primary / Secondary voting to select a
new Primary to pass the emergency to the System.
If a VRX1000 is in the OFF Mode when it receives an Emergency from a local
PSU, the VRX1000 will switch to System mode after the ‘Attempts Counter’ is
exceeded, affiliate the PSU and pass the Emergency to the System.
If a VRX1000 is on a ‘VR Disabled’ Mode and it receives an Emergency from a
local PSU with a valid steering NAC then after the ‘Attempts Counter’ is
exceeded, the VRX1000 will steer to the corresponding ‘VR Enabled’ MSU
mode, switch to SYSTEM mode, affiliate the PSU and pass the Emergency to the
System.
The PSU Emergency attempts counter must be programmed to be equal to the
VRX1000 ‘Attempts Counter’ plus 3.

Emergency Call
Emergency Call operation provides the user with access to a voice resource on a priority
basis. The user’s Emergency Call has priority over all other types of call traffic.
Upon receipt of an Emergency Call from a local PSU, the VRX1000 will proxy the call to
the FNE. The VRX1000 also updates its display to indicate the PSUs Emergency Call
condition. Upon PSU Cancellation of the Emergency Call, the VRX1000 will clear its
emergency display. The VRX1000 will also proxy the PSU emergency cancellation to the
P25 FNE. Emergency Hot MIC enables automatic emergency voice transmission without
having to press the PSU PTT. PSU Emergency Hot Mic is supported only on
‘DVRS/VRX Enabled’ PSUs. Only the ‘DVRS/VRX Enabled’ PSU waits for Emergency
Alarm ACK before requesting a voice channel. If Emergency Hot MIC is enabled in
Generic P25 PSUs (or ‘DVRS/VRX Enabled’ XTS PSUs with firmware older than
R12.00.13), the PSU will send emergency alarm and immediately enter the call phase,
which prevents consistent emergency processing.
Emergency Revert through VRX1000
The VRX1000 can be configured to revert local PSUs that have entered emergency by
mode steering the MSU to a preconfigured zone/channel. When the VRX1000 is
programmed for emergency revert and the MSU is not already in Emergency, the
VRX1000 steers the MSU to the preprogrammed zone/channel upon receiving and
Emergency Alarm / Call from the PSU. When the VRX1000 receives emergency
cancellation from the PSU, it steers the MSU back to the original zone / channel,
provided the MSU is not in emergency and the user has not manually changed the MSU
channel.
Emergency Revert through PSU
The PSU can be configured to revert to a preprogrammed talkgroup or zone / channel
when it enters Emergency. With the Talkgroup revert option, the PSU does not change
its mode but rather stays on the currently selected channel and performs all emergency
related voice and signaling by using the Revert Talkgroup ID. Talkgroup revert is only
supported on the APX ‘DVRS/VRX Enabled’ PSUs.
Emergency operation during TG Translation
Emergency operation is affected by TG Translation as follows:
Inbound Emergency Alarm received by the VRX1000 on TG X will be
translated to the ID of the TG selected on the MSU and forwarded to the FNE.
Outbound Emergency Alarm received by the MSU on the MSU selected TG
(TG Y) will be translated and repeated to the local PSUs on all translated TG IDs
that are selected on all Local PSUs, currently affiliated with the VRX1000.
Inbound Emergency Call on TG X will be translated by the VRX1000 to the ID
of the TG selected on the MSU and will be repeated on the translated TG to the
FNE.
Outbound Emergency call received on TG Y selected on the MSU will be
repeated by the VRX1000 to the Local PSUs on TG Y.
If Emergency Revert is programmed in the local PSU then:
If the revert TG is on the VRX1000 TG Translation list, then the Emergency will
be translated to the ID of the TG that is selected on the MSU.
February 2016 Page 59 of 92
8A087X02 R3
VRX1000
User’s Guide
If the revert TG is not in the VRX1000 TG Translation list then the emergency will
be proxied and the inbound and outbound repeat will be on the new emergency
revert TG.
If the MSU (interfaced to the Primary DVR) is placed in Emergency and
programmed to revert in Emergency then a subsequent local PSU emergency
will also be translated and declared on the MSU’s emergency revert TG.
Fireground (FG) Signaling
The VRX1000 supports FG Emergency signaling transmission from the Local PSU to the
FNE (if programmed in the VRX1000). Other types of FG signaling are discarded and
only the Local PSU user’s voice is transmitted from the Local PSU to the FNE in FG
applications.
PSU IV&D
The VRX1000 supports IV&D for only one PSU at any time. The use of PSU IV&D
requires P25 ‘DVRS/VRX Enabled’ PSUs, a VRX1000 in LOCAL or SYSTEM mode
operating on a P25 digital or Forced Analog channel, and MSU operating on a P25
Trunked mode. Voice operation and signaling (such as call alert etc.) initiated from the
MSU or PSU take priority over data operation.
NOTE:
PSU IV&D is not supported on ‘Generic P25’ PSUs or if the VRX1000 does not have
Option TT05953AA Installed.
PSU Location Reporting GPS
GPS is supported on ‘DVRS/VRX Enabled” PSUs when the MSU is operating on a P25
Trunked mode. PSU Location reporting (GPS) is supported on a single PSU via the
VRX1000. This feature relies on PSU IV&D functionality described above.
NOTE:
PSU GPS is not supported on ‘Generic P25’ PSUs or if the VRX1000 does not have
Option TT05953AA Installed.
PSU Call Alert
PSU Call Alert is supported via the VRX1000 when the MSU is operating on a P25
Trunked or P25 Conventional mode and when the PSU is either P25 ‘DVRS/VRX
Enabled’ or P25 Generic.
PSU Message
The Message feature is supported on all types of P25 PSUs when the MSU is operating
on a P25 Conventional mode only.
PSU Status Update and Status Request
The PSU Status Update & Status Request features are supported on all types of P25
PSUs when the MSU is operating on a P25 Conventional or P25 trunked mode.

Automatic PSU Revert to Talk Around (TA)
The ‘DVRS/VRX Enabled’ PSU can be programmed to automatically revert to TA and
continue to operate when it goes outside of the VRX1000 radio coverage range. This
way, simplex PSU-to-PSU calls (‘DVRS/VRX Enabled’ PSUs) will be allowed regardless
of the presence or absence of the VRX1000.
PSU Group Services
Pre-requisites for PSU Group Services support via VRX1000:
APX series ‘VRX1000/DVRS Enabled’ PSUs with Firmware R14.50.00 or later
P25 Trunked FNE with firmware 7.16 or later
VRX1000 with firmware R1.22 / MSU R14.50.00 or later
VRX1000 in SYSTEM or LOCAL Mode, Digital Channel Selected
MSU that VRX1000 is interfaced to receiving Group Services while on P25
Trunked FDMA Mode
The following Group Services can be supported by the VRX1000:
Group Text
Group text is an unconfirmed message that is sent to all members of a talkgroup. The
VRX1000 passes the Group Text messages to the local PSUs. If the Local
‘VRX1000/DVRS Enabled’ PSU users want to receive only Group Text Messages sent
to the PSU selected Talkgroup, then the PSU must be programmed for ‘Selective
Squelch’ instead of the default ‘Normal Squelch’. If programmed for ‘Normal Squelch’,
the Local PSU will receive all Group Text Messages proxied by the VRX1000 regardless
of the Talkgroup currently selected on the PSU.
NOTE:
The above also applies to voice calls in general – if the Local PSU users want their
PSUs to only unmute to the PSU selected Talkgroup, then they need to program
‘Selective Squelch’ in the PSU. If they are using the default ‘Normal Squelch’ setting, the
PSUs will unmute to all calls proxied by the VRX1000 regardless of the incoming call
Talkgroup.

Group Alias Update
Group Alias update is a message sent to a given Talkgroup while on a voice channel to
alert the receiving radio of the transmitting radio’s alias/ID configured in the Provisioning
Manager on the console. The updated Group Alias data is received by the members of
the Talkgroup and their Unified Call List (UCL) is updated. The VRX1000 passes the
Group Alias Update to the local ‘VRX1000/DVRS Enabled’ PSUs so that their UCLs can
get the update even while they are not directly connected to the trunked system but are
proxied via the VRX1000.
NOTE:
The updated Alias will be displayed on the receiving PSU only when the PSU is directly
affiliated on the trunking system. When affiliated through the VRX1000, the PSU will still
display the Unit ID of the transmitting PSU but it will not display the programmed or the
updated Alias for that transmitting Unit ID.
NOTE:
When the MSU is operating on TDMA mode, the MSU may receive group services but
will not proxy those to the VRX1000 / Local PSUs.

Forced Analog Mode
Forced Analog Mode is a hybrid mode in which the communications between the
DVRS/VRX Enabled’ PSU and the ‘DVRS/VRX Enabled’ P25 PSU are P25 digital, while
the voice communications are ‘forced’ to be analog when the MSU is on a non-P25
channel / Talkgroup. Forced analog mode is used only when the Local PSUs are
‘DVRS/VRX Enabled’. When the MSU is on analog conventional or 3600 Baud trunking
(analog or digital) or P25 TDMA channel, the DVRS/VRX1000 ‘forces’ the ‘DVRS/VRX
Enabled’ PSU to transmit analog voice. When the MSU is on a P25 channel / talkgroup,
the ‘DVRS/VRX Enabled’ PSU and the VRX1000 operate in P25 digital mode. At all
times the signaling between the ‘DVRS/VRX Enabled’ PSUs and the VRX1000 is digital
P25. The VRX1000 must be on a VRX1000 channel programmed for ‘F.Analog’ mode.
IMPORTANT!
Forced Analog Mode requires Option TT05953AA to be loaded in the VRX1000.
‘Generic P25’ PSUs can’t operate with a VRX1000 in Forced Analog Mode.

Analog Mode Operation
This Chapter provides details on the VRX1000 Analog Mode of operation.
The Analog Mode assumes the following:
APX4500 or APX6500 or APX7500 MSU Programmed for DVRS/VRX Operation.
PSU programmed for DVRS/VRX operation using a Conventional, Analog, non-
ASTRO Personality.
VRX1000 Channel used is programmed for Analog (or Mixed) Mode of
Operation.
VRX1000 Channel Setup for Analog Mode
To enable Analog VRX1000 operation on a specific VRX1000 channel the Channel Type
(in the Repeater Channel Setup Menu) must be set to Analog. The VRX1000 Tx = Rx
Frequency / Frequencies as well as the Tx / Rx PL or DPL must be programmed to
match the corresponding PSU settings.
NOTE:
Mixed VRX1000 mode allows Analog VRX1000 operation by switching between digital
and analog modes as described in the Mixed VRX1000 Mode section. The use of mixed
mode for analog VRX1000 communications is not recommended since it requires
special user training in order to handle the switching between default digital and
temporary analog mode. Mixed VRX1000 mode should only be used when both analog
and digital PSUs are required to operate on the same VRX1000 channel.
Group Calls
An analog local PSU in VRX1000 mode can communicate with other analog local PSUs
in Talk Around mode. Inbound Local PSU calls will be repeated on the MSU side over
the currently selected MSU TG / Channel. Outbound calls received by the MSU are
repeated to the Local Analog PSUs.
February 2016 Page 71 of 92
8A087X02 R3
VRX1000
User’s Guide
Emergency in Analog Mode
The Emergency operation in analog mode is based on the type of signaling as selected
in the Emergency Mode Setup Menu. The recommended analog mode signaling type is
MDC1200. MDC1200 signaling must be enabled in the local PSU personality. If
MDC1200 signaling is used, the Local PSU Emergency Alarm MDC ID will be passed
through to the system provided the MDC ID is enabled (valid) on the system side.
NOTE:
PSU PTT ID (MDC1200) pass-through is not supported by VRX1000 on Type 2 trunking
MSU modes.
Only Emergency ID (with Emergency Alarm) pass-through is supported by the VRX1000
on Type 2 trunking MSU modes.
Emergency Alarm
When an affiliated local PSU issues an Emergency Alarm, the active Primary VRX1000
will process the emergency to the system as follows:
If the ‘Portable ID Display’ box (in the VRX1000 Emergency Mode Setup) is
checked, the Local PSU Unit ID will be displayed on the MSU control head of the
current Primary VRX1000.
The PSU Unit ID will also appear on the display of the other local PSUs if they
are programmed accordingly.
The local PSU ID during Emergency may also be displayed on the dispatcher
console.
The VRX1000 sends back an Emergency ACK to prevent the PSU from re-
sending the Emergency either right after the VRX1000 decodes the Emergency
request (if the ‘System Acknowledge Type’ on the Mobile Radio Channel
Settings menu is set to “VR Ack”) or after FNE ACK has been received (if the
‘System Acknowledge Type’ on the Mobile Radio Channel Settings menu is
set to ‘Site Ack’ or ‘Console Ack’ ).
All Secondary VRX1000 in the area are monitoring the number of emergencies
issued by local PSUs according to the ‘Attempts Timeout’ and ‘Attempts
Counter’ settings programmed in the VRX1000s Emergency Mode Setup. If the
number of detected not serviced Emergency Attempts exceeds the counter, the
Secondary VRX1000s will go through Primary / Secondary voting to select a new
Primary to pass the emergency to the system.
If a VRX1000 is in the OFF mode when it receives an Emergency from a local
PSU, the VRX1000 will switch to SYSTEM mode after the ‘Attempts Counter’ is
exceeded, affiliate the PSU and pass the Emergency to the system.
The PSU Emergency attempts counter must be programmed to be equal to the
VRX1000 ‘Attempts Counter’ plus 3.
Emergency Call
Emergency Call operation provides the user with access to a voice resource on a priority
basis. The user’s Emergency Call has priority over all other types of call traffic. Upon
February 2016 Page 72 of 92
8A087X02 R3
VRX1000
User’s Guide
receipt of an Emergency Call from a local PSU, the VRX1000 will process the call locally
as well as proxy the call to the FNE. On Type II trunking systems, the PSU Emergency
Call will be proxied with the MSU Emergency ID, NOT the PSU MDC ID. The VRX1000
also updates its display to indicate the PSUs Emergency Call condition.
Emergency Revert
When the VRX1000 is programmed for emergency revert and the MSU is not already in
Emergency, the VRX1000 steers the MSU to the preprogrammed zone/channel upon
receiving and Emergency Alarm / Call from the PSU. The emergency revert condition
can be configured as permanent or timed. If configured as timed then the VRX1000 will
revert the MSU back to the original channel after the emergency inactivity timer expires
without inbound or outbound activity.
Analog Audio Buffering
Audio buffering is supported by the VRX1000 in order to eliminate loss of messages /
parts of messages due to the inherent delays associated with acquiring system access.
The analog buffer is programmable in the VRX1000 (up to 1300ms).
Tactical Public Safety (TPS)
The TPS feature allows analog subscribers to send digital PTT ID information on an
analog channel with analog voice. TPS is only supported when the VRX1000 is on an
analog channel in the SYSTEM mode and the MSU is configured for analog transmit
(without any signaling) and with Mixed receive.
Fireground (FG) Signaling
The VRX1000 supports FG Emergency signaling transmission from the Local PSU to the
FNE (if programmed in the VRX1000). Other types of FG signaling are discarded and
only the Local PSU user’s voice is transmitted from the Local PSU to the FNE in FG
applications.

Remote VRX1000 Activation via DTMF
The local PSU may be programmed to remotely activate the VRX1000 by switching it
from OFF or LOCAL to SYSTEM mode by sending a pre-programmed DTMF sequence.
The remote activation only works if the Local PSU and the VRX1000 are set to operate
on the same radio channel.
IMPORTANT!
The VRX1000 cannot be switched OFF remotely via DTMF.
P25 Encryption in Analog Mode
If the MSU is receiving a P25 Encrypted call while the VRX1000 is operating on analog
channel, the VRX1000 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
P25 Encrypted audio received by the MSU is processed by the VRX1000 as described
below:
*Local PSUs must be configured for Mixed receive.
Leading & Trailing Tones
The VRX1000 can be programmed to send over-the-air Leading or Trailing tones to the
LPSUs to indicate successful MSU key up / system access.
If Leading Tones are enabled, the local PSU operation involves the following:
User does a quick PTT of LPSU so that MSU can request channel grant
User releases the PTT for a moment and waits to hear the Leading tones.
If the Leading tones indicate successful system access (channel grant), the
LPSU user PTTs again and talks.
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 require
double PTT.
Both Leading and Trailing Tones are sent over-the-air (i.e. not generated in the PSU that
initiates the call) therefore all LPSUs that are within the VRX1000 range and switch to
the VRX1000 channel will hear the tones.

Mobile Mode Steering via PL/DPL
This feature allows a PSU User to remotely change the currently selected MSU mode by
transmitting with a pre-programmed PL/DPL. When the VRX1000 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.
The preprogrammed timer (‘MSU Mode Steering Hang Time’, Analog Setup) starts
after the local PSU (causing the steering) keys off.
Steering and Emergency
If steering is disabled on the current VRX1000 channel, local PSU emergency is
declared on the currently selected MSU channel (no steering).
If steering is enabled on the current VRX1000 channel, the local PSU emergency
is declared on the new (steered) MSU mode.
When MSU is in emergency call state (‘Put DVR in Emergency Call State’ is
enabled), the local PSU calls handling is defined by the ‘Steering in
Emergency’ programming for the specific VRX1000 channel. If ‘Steering in
Emergency’ is Disabled, the VRX1000 repeats any local PSU calls on the
emergency channel (no steering occurs).
If ‘Steering in Emergency’ is enabled, the VRX1000 will steer and then key up
the MSU. In this case the MSU will re-declare Emergency call on the new
(steered to) channel.
If ‘Put DVR in Emergency Call State’ is Disabled (local PSU and MSU
programmed for Emergency Alarm only), an inbound local PSU 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.
MSU Operating on TDMA (P25, Phase 2)
When the MSU is switched to a TDMA capable mode, the VRX1000 can operate in
either Analog or Forced Analog mode.
For Forced Analog mode operation, please refer to the Forced Analog Mode section of
this document.
When the VRX1000 is on an analog channel and the MSU is on a TDMA capable
channel, the following features are supported via the VRX1000:
Emergency Alarm and Call (MDC1200)
Group voice, Inbound and Outbound
MDC PTT-ID
Emergency ID
Status Update (MDC1200)
When operating on TDMA system, any TDMA specific feature that can cause the MSU
to interrupt an ongoing transmission will also affect the proxying of Local PSU
transmissions to the system. The Local PSU will not receive an indication that its proxy
transmission from the MSU to the system may have gotten interrupted.

User’s Guide
Mixed VRX1000 Mode
Mixed VRX1000 mode allows analog VRX1000 operation by switching between digital
and analog modes as described below. The use of mixed mode for analog VRX1000
communications is not recommended since it requires special user training to be able to
handle the switching between default digital and temporary analog mode as described
below.
Mixed VRX1000 mode should only be used when both analog and digital PSUs are
required to operate on the same VRX1000 channel. Mixed VRX1000 mode requires the
MSU to be switched to a P25 Digital channel. When a VRX1000 channel is programmed
to operate in mixed mode, the VRX1000 can handle calls from both P25 and analog
local PSUs while the same VRX1000 channel is selected.
When mixed mode is selected, the VRX1000 can be toggled between digital and analog
mode as follows:
The default VRX1000 mode is digital i.e. the P25 modem is enabled by default.
If a call from a local PSU is detected and the VRX1000 does not decode a P25
frame sync within the preprogrammed ‘P25 Frame Sync Detection Timer’, the
VRX1000 switches to analog mode and starts decoding analog mode signaling
(such as DTMF, MDC1200). The VRX1000 repeats analog signals to the system
MSUs / PSUs on the selected MSU channel / TG.
After the local PSU keys off, the VRX1000 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 MSU prior to the above timer’s expiration will be
repeated by the VRX1000 as analog conventional.
Once the ‘VR Ch Mixed Mode Hold Timer’ expires, the VRX1000 returns back
to digital mode and any outbound calls are repeated as digital. Inbound analog
calls received by the VRX1000 in mixed mode are repeated to the system by the
MSU on the selected TG / Channel.
If TG Proxing is enabled, digital inbound calls received by the VRX1000 are
transmitted by the MSU on the TG selected on the local PSU (not on the TG
selected on the MSU).

Special Features Support
TPS Signaling
Tactical Public Safety (TPS) Signaling support can be enabled on a VRX1000 channel,
operating in conjunction with a Conventional P25, Trunking P25, or Conventional Analog
mobile radio channel. This capability enables specially programmed local PSUs to
transmit TPS Leading and / or Trailing IDs. TPS Emergency can also be received and
processed by the VRX1000 when a TPS Enabled Analog channel is selected.
