Recommended Protocol/Standard. The detailed matrix will be maintained on the system database. An example of the matrix layout is shown in this manual. Need to develop the matrix layout. Each System Manager will maintain a master Fleetmap spreadsheet containing data on the subscribers for whom they are responsible.
Recommended Protocol/Standard. Interconnect usage shall only be programmed for the users of the system that have a need for the function, the primary purpose of the system is for radio communications, but there may be some users that may require a backup ability to cellular communications. The priority level for interconnect calls is “10,” this is defined under the priorities standards documents. The interconnect equipment of the system will be configured to use the “overdial” method of operation, where the incoming calls come into a generic phone number, and then the interconnect ID of the radio is entered to complete the call. The Fort Lauderdale radio system does not support inbound interconnection.
Recommended Protocol/Standard. Private call usage will only be programmed for the users of the system that have a need for the function the primary purpose of the system is for radio communications. Site access for private call is managed in the “Sites Profile Group” that the radio user belongs to.
Recommended Protocol/Standard. In order to meet this need the Radio User aliases would be prefixed with an agency identification that would be unique to that agency and would preferably readily identify the agency the Radio User is associated with. Because of the number of agencies using the system the prefix would be a minimum of two alphanumeric characters in length in order to avoid contention between agencies. Regional Operating Agencies and all agencies within the County of Broward would have naming prefixes of at least two digits that would stand alone. Counties would be pre-named with a two digit mnemonic, and the Cities and Agencies of the Counties would be included under the prefix of the County they are in.
Recommended Protocol/Standard. The first two characters of the TG alias identify the talk group governing entity/municipality (see Table 1). The third character identifies the department/agency within the governing entity/municipality (see Table 2). The fourth character will have a dash (-) as a separator. The remaining available characters will be used to complete the talk group alias. It is important to note, depending on the subscriber type and/or model, character display may be smaller or larger. Subscribers units with displays smaller than twelve (12) characters will require condensing the TG name to fit within the display. Any subscriber displays that are under eight (8) characters will be handled, by the Radio System Administrator, on a case by case basis. It is understood that there is currently a wide variety of subscribers out in the field. In addition to this, there are many agencies who still wish to continue to identify zone and channel assignments prior to the TG in the subscriber unit. Even though the concept that the TG’s are to remain consistent from zone controller up to the subscriber is fully supported by Broward County Office of Communications Technology, this may be too big of a challenge to overcome at this time. We have come to the understanding that if the agency wishes to continue to identify zone and channel assignment prior to the TG name in the subscriber, they have this ability if they can leave the TG name consistent, as it appears in the zone controller, as much as possible.
Recommended Protocol/Standard. Use of the Emergency Button as an emergency signaling option should be available to any agency on the radio system, subject to certain conditions and provisions.
Recommended Protocol/Standard. In order to meet these requirements the following information describes the minimum standards that must be considered when new radios are purchased. Radios of various manufacturers and models are capable of operating on this network. The Network currently consists of a Motorola SmartZone 3600 Baud Control Channel infrastructure. It is recommended that mobiles and portables be capable of operation with SmartZone features to permit the automatic roaming between sites as the users move out of range of their home system. SmartNet radios can be utilized where there is no intention of providing the automatic roaming features. With an eye to the future, where P25 and 700 MHz may be introduced, it is recommended that the subscriber units with a life expectancy past 2009 be either upgradeable or be equipped to operate on 700 MHz using the P25 protocol. For Public Safety users it is strongly recommended that the current Motorola products be utilized. System Managers can advise on the appropriate features, functionality and options to purchase. As a minimum, all radios shall have the ability to be assigned a unique individual ID number for system access, have the ability to be inhibited by command from the System Management tools and have an adequate talkgroup/channel capacity to permit the Local, Regional and National Mutual Aid talkgroups and channels to be programmed along with local agency requirements. The radios shall be capable of operating both in conventional mode and Motorola Trunking modes. There are other Trunking protocols that are not compatible, and radios utilizing these protocols shall not be authorized. These protocols include, but may not be limited to, Privacy Plus, EDACS, LTR and TETRA. Mobile Radios shall have their power set to the lowest possible value. The radio systems in Broward County are designed to work in-building with portable radios. Constraints are placed upon the acceptable mobile radio power levels that should be utilized by this in-building design and the close spacing of the frequencies utilized by the network. Excessive power can cause undesired interference to the other users on the network. Older model radios shall be set to the lowest power permitted by their design, typically the half-power point. Non-Public Safety mobiles shall utilize 1/4 wave antennas, not gain style antennas. Any Public Safety user that desires to utilize a high power setting for a specific System’s Talk Groups shall obtain permission from the System Man...
Recommended Protocol/Standard. The use of the following codes, which are combined to define the intended pre-authorizations… P = Permission is required to gain authorization for use. A letter of permission must be generated from the System Manager of that agency that wishes to use another agency's Talk Groups for their radio subscribers and/or their Dispatch consoles and this written request must be sent to the System Manager of the system that has ownership of those Talk Groups for their system. D = Defined agencies may share, to be defined in a separate letter. The letter would outline specific purpose talk groups, i.e., only dispatch consoles, only neighboring cities, etc. The letter will be on file with the appropriate System Managers. L = Like agencies may share, “Fire, Medical, Law, Public Works, etc.” A = All agencies. RX = Only authorized to receive. TX = Authorized to transmit and receive.
Recommended Protocol/Standard. Limited Scanning/monitoring privileges may be pre-approved by the affected Talk Group owners and System Managers. Before Scanning of owned Talk Groups, permission must be granted. permission must come from: The System Managers of the sites that are being requested for the Talk Group The jurisdiction/agency who is the “owner” of the requested Talk Group Mutual aid, special roaming and other shared Talk Groups may be Scanned at any time; however, “requested site” determinations will be made by the System Managers of the affected sites.
Recommended Protocol/Standard. In order to meet these requirements the following information describes the minimum standards that must be considered when new auxiliary radio equipment is purchased. the AdvanceTec model as appropriate for the radio model in use. These shall only be utilized to charge the spare battery. It is highly encouraged that OEM batteries be utilized as they have proven to present fewer quality and performance issues then many of the after-market products. After-market batteries shall be evaluated prior to implementing their use. Testing shall include fit and finish, drop tests, vibration, cycle capacity, long-term capacity and self-discharge after the battery has been in use for six (6) months. Testing shall be on a representative sample of the after-market manufacturer’s product. Speaker/Microphones: Speaker/Microphones come in two basic styles; Public Safety – equipped with an antenna; Standard – usually equipped with a coiled cord and does not have antenna. The radio system coverage is predicated upon the use of a Public Safety microphone with the appropriate antenna installed on the microphone. Use of Standard speaker/microphones for users that ride in vehicles is discouraged due to the significant range reduction caused by having the antenna below the vehicle glass level and shielded by the vehicle’s construction. They may be utilized by bicycle and motorcycle units with the understanding that when radio user is in a vehicle, the coverage may be significantly reduced. Surveillance kits such as the two or three wire kits, and ComPorts also utilize the antenna mounted on the radio. The same in vehicle coverage issues apply to these units. After-market microphones, surveillance kits, etc. require technical evaluation by the System Manager before they are promoted to the end users. The following are the manufacturer’s recommend standard specific to radio models MTS2000 (antennas only), XTS3000 and XTS5000 (batteries only) series. 806 – 870 MHz – ½” Wavelength Whip (MTS2000 only) 806 – 941 MHz – ¼” Wavelength Whip (MTS2000 only) Straight Cable 24 inches Straight Cable 18 inches Command Shoulder Speaker (water-proof) microphone Ultra-High Capacity Battery (MTS2000) High Capacity NiCD High Capacity NiCD FM High Capacity NiMH High Capacity NiMH FM High Capacity NiMH Rugged FM High Capacity Lithium Ion NiCAD (State approved)
