CHAPTER 1—Welcome to the OpenSky Network2222                    M-803 Operator Manual Software Version OTP 5.07OpenSky OverviewM/A-COM’s OpenSky is a suite of radio communi-cations products implementing an integrated digitalvoice and data system based on the Internet Protocol.The OpenSky network is digital, but provides inter-operability with analog radios, making it possible tointegrate existing (legacy) equipment alongside themost sophisticated digital equipment available today.If you’ve been issued an M-803 to replace aconventional analog voice-only radio, you’llparticularly appreciate the integrated voice and datacapabilities of the all-digital OpenSky mobileequipment.Even experienced digital subscribers recognize andvalue the addressability precision and expandedcoverage strength of the end-to-end TCP/IP OpenSkyIntranet.Internet Protocol (IP) NetworkOpenSky’s Wireless Private Network is changing thenature of real-time communications for large fleetmobile businesses and public safety organizationsalike.TCP / IP BackboneUsing Internet Protocol (IP) as a network backbone forend-to-end user applications, OpenSky integratesdigital voice and packet data transmission over a singlenetwork that provides significant performanceadvantages over yesterday’s uneasy alliances ofindependently-built radio networks tryingunsuccessfully to interact.• Like tuning into a channel in a conventional FMradio system, logging onto the OpenSky networkwith your pre-configured user profile will placeyou in contact with the members of a software-
Welcome to the OpenSky Network—CHAPTER 1Software Version OTP 5.07 M-803 Operator Manual     3333defined talk group consisting of the set of usersyou need to talk with most.• Unlike your conventional FM radio, your M-803mobile radio is a node on an Internet-Protocol (IP)network with its own unique IP address.Addressable HeadersMessages intended for you (whether voice or data) arebroken into packets with identifying headers, just likeWorld Wide Web internet communications, andtargeted to your specific IP address.You can travel anywhere within your network, even ahundred miles or more from the sender, and messagesintended for your IP address will find their way acrossthe network, handed off from base station to basestation, until they are re-configured and delivered toyour personal receiving set.This doesn’t mean your communications are travelingacross the World Wide Web. Far from it. OpenSky is aprivate wireless Intranet that adopts the best features ofIP protocol for increased communications efficiencyand capacity.System-Wide Voice EncryptabilityFurthermore, your communications are packeted asthey travel the network, so they can only be decipheredby networked equipment. Your sensitive conversationsand data transfers can even be encrypted end-to-end forenhanced system-wide security.Integrated Voice and DataYour M-803 Gemini Series Mobile Radio is ahardware component of the OpenSky network, anintegrated voice and data communications system thatdelivers end-to-end digital voice and data transmissionsover a single wireless network to your dash-mounted ortrunk-mounted device.Like cell-phone calls,messages are delivereddirectly to yourequipment.But, like radio calls, usersselect which calls toreceive by “tuning in” or“locking out” other usergroups.
CHAPTER 1—Welcome to the OpenSky Network4444                    M-803 Operator Manual Software Version OTP 5.07Digitized Voice, Text and GraphicsBy converting analog voice waves to digital codebefore transmitting them over the network, OpenSkytechnology makes it possible for mobile radio users tosend and receive voice transmissions at the same timethey receive and view data (via the radio’s serial port)on an optional equipment Mobile Data Terminal.For graphics, interface aMobile Data Terminal(MDT) through yourradio’s RS-232 peripheralport.With an M-803 in your vehicle, you’ll be able to scrollthrough complex instructions, driving directions, oremergency warnings on an optional mobile computeror terminal device while at the same time carrying onconversations with dispatchers or other mobileoperators in your coverage area.OpenSky and the M-803 eliminate the need to runseparate systems for voice communication and datatransmission. And, with OpenSky, you won’t evenhave to switch between radio modes to do bothsimultaneously.RS-232 InterfaceFor data transfers or graphics, your M-803 isconstructed with an industry-standard RS-232 interfaceserial port for connecting an optional equipmentMobile Data Terminal (MDT), laptop PC or third-partydisplay or key-entry device.OpenSky works seamlessly with equipment frompopular manufacturers and off-the-shelf applicationsthrough a standard UDP/IP protocol, providing youwith simple “plug and play” connectivity.Suddenly and simply, the same M-803 you’ve beenusing for voice conversation and tuning radiofrequencies becomes the device you use to viewphotographs, maps or driving directions, generatereports, access databases, in short to share any digitalfile your job requires.
Welcome to the OpenSky Network—CHAPTER 1Software Version OTP 5.07 M-803 Operator Manual     5555Multi-Agency CoverageOpenSky is scalable and designed to accommodate avirtually unlimited number of mobile and portabledevices from a single fleet, or even a complex networkmade up of several cooperating agencies.Examples of how OpenSky improves cooperation:• Every truck in the FedEx fleet can share one largenational network.• Every cruiser in a state-wide police agency cancommunicate with any other cruiser, from one endof the state to the other.• Patrolmen with older analog equipment canconnect seamlessly with newer digital devices overthe same network.• Emergency response agencies share the samenetwork for improved communications during amassive crisis.• With an M-803 at the heart of your trunk-mountedVTac Vehicular Tactical Network, your vehicleprovides off-network user-to-user communicationsat the scene of an emergency.Promotes Interagency CooperationSee full discussions ofTalk Group, User Groupand User Profile else-where in this manual.In fact, the system is best suited to multi-agency publicsafety networks over areas as large as an entire state:every cruiser, ambulance and fire truck and all theirdispatchers and support personnel sharing voice, data,even graphics over the same network.Talk to Anyone on the NetworkEach user needs only one radio to connect seamlesslyto many independent agencies or cooperating dispatchnetworks.• There’s no need to monitor multiple frequencies onseveral pieces of equipment to maintain contact.
CHAPTER 1—Welcome to the OpenSky Network6666                    M-803 Operator Manual Software Version OTP 5.07• User talk groups connect you at all times withprecisely the users you need to reach, no matterwho they work for, or where they’re located withinthe network.Connectivity with Legacy EquipmentThe all-digital, end-to-end TCP/IP OpenSky Intraneteven provides support for legacy equipment andprotocols both digital and analog.Along with supplying voice and data to your M-803mobile radio, the network will also support existing (or“legacy”) radio equipment you may still need to useduring a hardware rollover.This also means you’ll be able to make radio contactwith cooperating agencies on the same network,whether or not they have made the conversion toOpenSky equipment, as long as they use their radios tonetwork with OpenSky.Voice and Data to a Single DeviceFor graphics, you’ll needto remain connected toyour Mobile DataTerminal (MDT).With OpenSky, you won’t need independent systemarchitecture to receive voice and data communications.And, with a Mobile Data Terminal connected throughthe peripheral interface, you’ll have unprecedentedability to send and receive forms, NCIC profiles, maps,floorplans, all the complicated graphical data you needto make informed on-the-job decisions.Improved Coverage and Signal StrengthPart of OpenSky’s scalability is its ability to accommo-date as many base stations as your coverage arearequires for robust voice and data transmissions,wherever your route may extend within the network.Vehicular Tactical NetworkVTac devices (trunk-mounted M-803 radios arrayedwith a duplexer and a vehicular repeater) and OpenSkycell sites automatically extend coverage into otherwisehard-to-reach areas.
Welcome to the OpenSky Network—CHAPTER 1Software Version OTP 5.07 M-803 Operator Manual     7777With a VTac device in your vehicle, you’ll enjoyextended signal reach into buildings or behind barriers,as well as repeater capability for off-network unit-to-unit communications.Background Roaming and SwitchingAutomated switching takes place in the backgroundwith OpenSky, so you’ll no longer be required to scanfor an open channel, or wait for an available channel,when you move through your coverage area.Signal strength sensitivityis user-modifiable toreflect local conditions.Instead of depending on choices from a centralswitching station, your radio itself constantly monitorssignal strength and makes its own decision to roam toanother base site for a more robust connection.Chances are you’ll never know your unit has been“handed off” to a new base station and automaticallyassigned to the best available channel.Better Peak-Time PerformanceOpenSky’s digital trunking architecture providesenormous advantages over conventional FM operation.Conversation capacity is effectively doubled by thesystem’s ability to carry two voice-to-voice conver-sations over the same channel that was previouslydedicated to just one.TDMA TechnologyThe M-803 uses TDMA technology to allow multipleusers to share a single RF channel. In addition, a single25kHz RF channel can support simultaneous digitalvoice and data communications.By doubling the capacity of each channel, the OpenSkyTDMA network relieves the pressure of heavy usewithout additional channels.The M-803 supports multiple voice groups, multi-levelpriorities, priority scanning, dynamic voice groupassignment, pre-emptive emergency calls and optionalencryption.
CHAPTER 1—Welcome to the OpenSky Network8888                    M-803 Operator Manual Software Version OTP 5.07Optional GPS TrackingGPS tracking devices embedded in optionally-equippedM-803 radios quickly and accurately locate users on avisual display screen for dispatchers, virtuallyeliminating the need for users to report their position.With an overview of the locations of all vehicles,dispatchers have the information they need to assignthe nearest vehicle to a developing emergency.By eliminating the background chatter of constantlocation reporting, OpenSky frees up system resourcesfor more critical communications, especially at peaktraffic times.Software-Configured DeviceYour M-803 is a “soft” radio. Its functions are deter-mined by OpenSky software applications, in much thesame way computer hardware is configured fordifferent applications.Unlike older analog radios you may have used, withtheir hardware-based proprietary functions, yourM-803 converts voice waves into digital informationbefore it transmits to the network, providing noise-freeaudio transmission and reception.Make any radio in thesystem “your radio” bylogging on with youridentity code.What’s more, because each user in the network has aunique identity code, you can activate your identityfrom any radio connected to the network. Any radiofrom your agency’s hardware stockpile can become“your” radio and log on with your profile.Multi-Mode FunctionalityFinally, if you need to be multi-mode, your M-803supports several (even several applications simulta-neously) providing capability with the needs ofdifferent user groups.You can operate under the OpenSky digital protocol oruse the same device to access Conventional FM withCTCSS analog FM or APCO Project 25 Phase 1operations, depending on the user configuration of yournetwork or agency.GPS tracking uses asmall fraction ofsystem resources,but eliminates verballocation reporting forhuge overallcapability gains.
Welcome to the OpenSky Network—CHAPTER 1Software Version OTP 5.07 M-803 Operator Manual     9999Analog-to-Digital RolloverThe M-803 can work with existing analog infra-structure to enable an essentially seamless transition tofully digital communicationsIf your user group or another user group with whomyou communicate is making the transition from analogto digital service over time, you’ll be able to use yourM-803 throughout the rollover by selecting the correctmode.What’s more, the M-803 is field re-programmable overthe radio channel to allow for future capabilitieswithout replacing the existing subscriber equipment.• The principle operating mode currently in use isthe OpenSky Trunked Protocol (OTP).• From the Mode Selection Menu, you can alsoaccess OpenSky Conventional FM (OCF) withContinuous Tone Coded Squelch System(CTCSS).• From the Mode Selection Menu, you can alsoaccess OpenSky Conventional (OCF) mode usingAPCO Project 25 Common Air Interface.Software UpgradeableAs with computer hardware, your mobile radioequipment is upgradeable each time the OpenSkysoftware enables a new feature or operationalenhancement.Communications protocols, radio features, andprotocols can be changed easily and transparently tothe user, during a shift or during “sign-on” at thebeginning of a new shift.Enhanced Digital FeaturesThe all-digital network and OpenSky’s digital trunkingfeatures also enable a rich array of network enhance-ments unthinkable over historical FM broadcastsystems.See full discussions ofTalk Group, UserGroup and profiles inChapter 2 of thismanual.

These usergroups are then organized into Profiles (collections ofup to 16 user groups), similar to banks of channels.Finally, as many as 16 profiles make up your radioPersonality.Only one profile is active at any time. Within thatprofile, only one user group is your Talk Group; theothers are Listen Groups. So, while you havetremendous capability to establish contact with a verylarge number of users, you’ll need to select the profilethat puts you into voice contact with the talk group youneed at any time.
Network Organization—CHAPTER 2Software Version OTP 5.07 M-803 Operator Manual     13User GroupsA user group is a set of users who regularly need tocommunicate (all the officers in a state police barracks,for instance, or all the drivers who work a particularshift).• In conventional FM radio broadcast systems,these users work together by tuning to the samechannel.• In the IP-backbone OpenSky digital network,subscribers in a user group are connected by a bitof data in the header of every voice or data packetaddressed to the members of the group.With OpenSky, members of the same user group canstay in contact regardless of where they roam withinthe network, whether the network incorporates a singlecounty, a state, even the entire nation.Network capacity is theonly limitation on thenumber of users that canmake up a group.Dispatchers maintain contact with all members of thegroup, and each user can stay in “push-to-talk” contactwith the dispatcher and all the users in their talk group,even if those users are from different, inter-networkedagencies.The Figure below illustrates a small user group of fourM-803 mobile radios.Figure 1 User GroupSample ConfigurationNothing about this user group so far defines it as a TalkGroup or a Listen Group. That determination is madewhen user groups are gathered together by the networkadministrator into the larger groups called profiles.Each radio assignedto an individual user
CHAPTER 2—Network Organization14141414                    M-803 Operator Manual     Software Version OTP 5.07ProfilesA profile is a set of up to 16 user groups. All sorts ofconfigurations are possible within this simplearchitecture. Police officers on the same shift mightmake up a profile, for instance. Within this profile,each police station on the network might be assigned auser group. So the profile would connect all thecruisers from 16 stations for an entire shift.Officers from each station would most likely be in“push-to-talk” contact with one another; all otherofficers on the same shift would most likely monitorthe other groups for “listen-only” access to all othercalls within the profile. But this is only one possibleconfiguration.Members of a talk groupare not necessarilyscanning the calls of thesame listen groups.A user group might just as easily include officers fromseveral stations: a SWAT team, for example, or aspecial emergency task force might require thecollaboration of special personnel or equipment fromdifferent police stations, or even other agencies.• In conventional FM radio broadcast systems,users with this sort of relationship would create an“ad hoc” profile by tuning to one channel for talk-group privileges and scanning an entire bank ofchannels to monitor the conversations of othergroups.• In the IP-backbone OpenSky digital network,members of the same talk group automaticallyreceive every voice message addressed to thegroup, and monitor the voice messages of everyother user group in the profile.Each user in the OpenSky network can be assigned asmany as 16 profiles by the network administrator. Atany time during a network session, users can select theprofile that suits their needs by using the front controlkeypad to access the Profile Menu. If selected forDwell Display, the Current Profile selection will bevisible in the radio’s front panel display area.Of the 16 availableprofiles, NetworkAdministrators will oftenreserve one for DynamicRegroup use.

All the other user groups in your profileare listen-only groups. You’ll hear the calls from thesegroups but they will not hear your voice unless youruser group is part of their profile.To initiate voice-to-voice contact with a particular user,you’ll have to select the profile that makes that userpart of your talk group. This is only possible if yournetwork administrator has configured a talk group thatcontains both you and the other user.If each of you has a profile that includes the other in atalk group, you can each select the profile that puts youinto “push-to-talk” contact with the other. (Or one ofyou can reply to the other in Talkback Mode.)Listen GroupsAll the other user groups in each of your up to 16profiles are “listen groups”. See the User ProfileFigure above for an illustration of how user groups arerelated in a profile.By adding different listen groups to your severalprofiles, your network administrator can change theconfiguration of the user groups you can monitor at anytime by making the appropriate choice from the Profilemenu.Talk Group Up to 15 Listen Groups
CHAPTER 2—Network Organization16161616                    M-803 Operator Manual     Software Version OTP 5.07You may only have one talk group, but that doesn’tkeep you from tuning in different profiles to monitor adifferent “bank of channels.”Talkback ScanningWhile you cannot initiate contact with users in your“listen groups,” you can reply to their incoming callsusing Talkback Scan mode.With your radio in Talkback Mode, your display screenwill show the identity of your most recent incomingcaller. Press the Push-to-Talk button on your handsetand send your voice reply.Radio PersonalityYour radio personality is a collection of up to 16profiles. The entire personality is organized by yournetwork administrator and is unique to yourcommunication needs.When you activate your radio at the beginning of ashift and sign on with your unique identity code, yourradio is assigned its IP address and “provisioned” witha radio personality that identifies the other users on thenetwork with whom you are most likely to need tocommunicate by voice.Your overall radio personality is organized into UserGroups (talk groups and listen groups), similar to achannel in a conventional FM radio system. These usergroups are then organized into Profiles (collections ofup to 16 user groups), similar to banks of channels.Finally, as many as 16 profiles make up yourpersonality.If an emergency promptsyour  NetworkAdministrator to enact aDynamic Regrouping ofuser groups, you’ll beprompted to conduct amid-shift log-on to re-provision your radio withan updated personality thatincludes a pre-programmed or ad hocemergency user profile.

Network administrators caneven create ad hoc work groups and profiles to respondto emergent conditions, then prompt the affected usersto re-provision their equipment while the emergencyunfolds.With 16 profiles you can participate in as many as 16talk groups. Or, if you only need one talk group, youcan still have up to 16 different profiles that can addmore than 200 other user groups to your listen grouppool, each with an almost unlimited number ofsubscribers.Of course, with potentially hundreds of voice calls inyour profile at any time, you’ll appreciate the ability toestablish Priority Scan groups, or even Lock Out othersto help focus your incoming calls.

CHAPTER 3—Controls and Indicators20   M-803 Operator Manual     Software Version OTP 5.07Before Your First ShiftIf you’re already familiar with mobile radio functionsand the “profile and personality” architecture of an all-digital network, you’ll find the features and controls ofyour new M-803 to be logically arranged and easy tounderstand.But if you’re new to cellular radio service, andespecially if you’re migrating to OpenSky from ananalog radio environment, take some time to review theNetwork Organization chapter of this manual beforeoperating your radio.In either situation you’ll want to completely familiarizeyourself with the controls and indicators of your newradio before you start trying to use it on the job. Inparticular, you’ll want to be able to scroll your waythrough menu display choices and quickly select theappropriate radio profile for the changing conditions ofyour work day.Radio ControlsExamine your radio thoroughly and familiarizeyourself with the location and operation of its controlsand indicators before studying their functions. Exceptfor the rear-panel peripheral interface, all theoperational controls for the M-803 are located on thecontrol panel or handset.Whether your passenger compartment is equipped witha dash-mount Mobile Radio Unit (MRU) or asubsidiary Control Head Unit (CHU), the followingsection will introduce you to all the controls andindicators of your radio’s front panel.Don’t read this manualcover-to-cover.Most information in thismanual is repeated inseveral places.You’ll probably learn mostof what you need to knowby browsing sections thatinterest you most.
Controls and Indicators—CHAPTER 3Software Version OTP 5.07 M-803 Operator Manual     21Front Panel ComponentsThe front panel of your M-803 (or CH-103) includesthe Power Button/Speaker Volume Dial, the Micro-phone/Speaker I/O Port, a 5-key “soft-button” keypadfor making menu selections, a 19-character vacuumfluorescent Display Panel, 3 Mode Selector buttons, anEmergency Button and an Ambient Light sensor.Your Push-to-Talk button is located on your hand-helddetachable microphone or hands-free speaker box (notshown here).Because an M-803 mobile radio can support as manyas five Control Heads, your installation may or maynot include the hardware “box” behind the front panel.The figure below shows the complete dash-mountedconfiguration of an M-803 mobile radio complete withfront control panel.Peripheral equipment such as a mobile computer ordata terminal connect to the M-803 through the rear-panel peripheral interface.Figure 4 Front Panel ComponentsDash-Mount M-803 Standalone ConfigurationPower andVolume DialAmbient Light SensorMic/SpeakerConnectorMenu and Selector Keypad EmergencyButton Display PanelMode SelectorButtonsUp to five Control HeadUnits (CHU) can besupported by a  singleMobile Radio Unit (MRU).The most typical multipleCHU configuration wouldbe a large fire truck orother vehicle with a dash-or trunk-mounted M-803and auxiliary control headspositioned elsewhere onthe vehicle.

CHAPTER 8—VTac Vehicular Tactical Network82   M-803 Operator Manual     Software Version OTP 5.07Vehicular Tactical NetworkThe Vehicular Tactical Network (VTac-803) is an 800MHz software-based digital mobile network repeaterfor extending network coverage to portable radios,providing scene-of-incident capability and the fullfeature set of an M-803 mobile radio.VTac supports the OpenSky communication protocolin the 800 MHz SMR and NPSPAC frequency bandswith a high performance data modem that gatewaysboth voice and data to the OpenSky wide area wirelessdata network.More capable than a stand-alone M-803, the VTac-803is a hybrid product that combines several hardwarecomponents into a multi-use communications device toextend the capabilities of a movable Base Stationwherever you position your vehicle.Backward and Forward CompatibilityThe software-based architecture allows the VTac-803to be programmed for a variety of modulationtechniques, providing legacy support and guardingagainst obsolescence.VTac can host several applications simultaneously tosupport users running the OpenSky digital protocol,Conventional FM with CTCSS, or Project 25 Phase 1.Over-the-Air ProgrammabilityFor agencies engaged in an analog-to-digital transition,The VTac-803 can function with existing analoginfrastructure today and, when the time is right, receiveover-the-air field reprogramming for a virtuallyseamless transition to fully digital communicationswithout replacing equipment.
VTac Vehicular Tactical Network —CHAPTER 8Software Version OTP 5.07 M-803 Operator Manual     83Operational ModesBy combining the functions of several components, theVTac-803 operates in a variety of modes:• Mobile Radio. This is the default mode ofoperation activated at Power-Up. Under ordinaryconditions, the VTac-803 is a fully-functioningsubscriber device performing all the functions ofan M-803 radio on the OpenSky network;• Extended Coverage. In weak coverage areas, theVTac Base Station can be activated to act as amobile base station, extending OpenSky networkconnectivity to portable radios in the vicinity. TheVTac continues to provide normal mobile radiofunctions in Extended Coverage mode;• Scene-of-Incident. For radios on the OpenSkynetwork, VTac acts as a voice repeater in OpenSkyTrunked mode, supporting two concurrent voicecalls between subscribers at the scene;• Mutual Aid. For radios not on the OpenSkynetwork, VTac can still provide a limited set ofcommunication capabilities, acting in Scene-of-Incident mode as a public safety “micro-cell” toconnect users in a conventional FM Mutual Aidnetwork.“A Base Station in a Trunk”Most commonly, VTac is a trunk-mounted installationof components that adds the most important functionsof a single-channel OpenSky Base Station to the radiofunctions of an M-803 Mobile.The VTac-803 is designed specifically with the PublicSafety user in mind. Its digital interface easily connectsto peripheral devices including the Control Head andCAN Peripherals that are often used to support thePublic Safety mission.
CHAPTER 8—VTac Vehicular Tactical Network84   M-803 Operator Manual     Software Version OTP 5.07Hardware ComponentsThe VTac-803 is a 4-piece array of hardwarecomponents consisting of:• An M-803 Full Duplex Trunk Mounted MobileRadio Unit (MRU), also known in thisconfiguration as the VTac Mobile;• A VTac Base Unit. This component brings thecommunications interface and transceiverfunctionalities of an OpenSky Base Station DCXto the trunk of a patrol car;• An RF combiner;• A CH-103 Control Head located in the passengercompartment of the vehicle controls the threetrunk-mounted components.Additional Control Head units may be locatedelsewhere in larger vehicles for user convenience.VTac Mobile UnitThe VTac Mobile provides the connection between theOpenSky network, operator, mobile data terminal, andthe VTac Base Unit.As a mobile radio, it operates like a standard-installation M-803, providing network communicationsfor a single vehicle through one or more CH-103Control Head Units.In a VTac installation, the VTac Mobile is connected tothe VTac Base Unit by a serial cable that conductsvoice and data between the two components.One-Button ActivationPowering Up the VTac Mobile automatically enablesall the connected hardware components of the VTacarray. Unless they’re needed, though, the RF Combinerand VTac Base Unit stand by in a quiescent state untilcalled on for use.
VTac Vehicular Tactical Network —CHAPTER 8Software Version OTP 5.07 M-803 Operator Manual     85VTac Base UnitThe VTac Base Unit has the same transceiver anddigital controller components as the OpenSky BaseStation DCX, but in a VTac installation thesecomponents only operate as needed, when enabled bythe subscriber.When Extended Coverage is required, the VTac BaseUnit provides the extended connection between thenetwork and portable radios in the vicinity.When Scene-of-Incident coverage is required, theVTac Base Unit provides communication betweensubscriber devices at the scene.RF CombinerThe RF Combiner provides the VTac Network with theability to create an ad hoc talk group for Scene-of-Incident emergency communications.Extended CoverageThe VTac-803 can be used as a mobile base station toensure that portable radios are connected to thenetwork at all times, in-building, or out.Subscribers with VTac equipment can enable ExtendedCoverage mode before leaving their vehicles to enterbuildings or spotty coverage areas, thereby assuringsignal strength to networked portables.User InteractionExtended Coverage requires subscriber activation.Without interaction the subscriber’s mobile andportable radios are served by the nearest network cell.By selecting Extended Coverage mode, the subscriberactivates the VTac Base Unit as a local cell on theOpenSky network.
CHAPTER 8—VTac Vehicular Tactical Network86   M-803 Operator Manual     Software Version OTP 5.07Scene of IncidentThe VTac-803 can also be a vital link at the scene of anincident, providing a repeater among OpenSky sub-scriber radios, or alternatively, among radios in aMutual Aid network that connects different radio types,whether they subscribe to OpenSky or not.In Scene-of-Incident (SOI) Mode, OpenSky Networkcommunications are sacrificed to enable full emer-gency connectivity between cooperating agencies at thescene. The tradeoff of network isolation providesincreased channel capacity while relieving traffic forother subscribers on the network.In Scene of Incident mode with OpenSky Trunking,VTac supports multiple talk groups. Like a tower sitebase station, it continues to support agency-specifictalk groups while at the same time creating an ad hoctalkgroup for units at the scene.User InteractionScene-of-Incident coverage is not automatic. TheVTac-equipped subscriber will make an on-scenecommand decision to manually activate SOI mode andbecome the local cell for all calls on an ad hocnetwork.In addition, all portable radio users must select SOImode and tune to the VTac frequency to join theemergency network.Public Safety HardenedThe VTac-803 is designed specifically with the PublicSafety user in mind.The case is manufactured with enhanced environmentalhardening making the VTac compliant withMIL-STD-810 for temperature, altitude, solarradiation, rain, humidity, salt, fog, sand, dust, vibration,and shock, ensuring that it will perform under the widerange of public safety environmental conditions.
VTac Vehicular Tactical Network —CHAPTER 8Software Version OTP 5.07 M-803 Operator Manual     87GPS OptionThe OpenSky VTac-803 can be supplied with anoptional embedded GPS receiver. GPS data can bereported either over-the-air to remote dispatchpositions or to a local terminal connected directly to themobile radio.Additionally the I/O connector provides a serial GPSport which outputs GPS NEMA messages. Reportingcharacteristics can be configured remotely and can beevent driven.GPS functions are transparent to the subscriber andrequire no user interaction.Connectivity InterfaceThe VR-803 supports a variety of interfaces with itsflexible interconnect. The M-803 and VRB connect tothe RF Combiner via the antenna ports located on therear panel.Peripheral SupportThe rear panel also provides interfaces for both analogand digital peripherals.The serial RS-232 port operates in asynchronousASCII mode for configuration and control and switchesto Serial Line Internet Protocol (SLIP) mode for datacommunication between the fixed network and amobile computer or terminal device.
