Common use of Technical Background Clause in Contracts

Technical Background.  Capabilities The network infrastructure and subscriber units need to be configured to permit managed user Scanning of Talk Groups. Whether or not Scanning will be utilized in subscriber radios, it is at the option of the user agency. Users also need to be trained that merely including a Talk Group in a non-priority Scan list will not necessarily result in the user hearing traffic on that Talk Group. The Talk Group must also be “active” at the site where the user is affiliated. Talk Groups are active on a site if the Zone Controller is programmed to allow the Talk Group to appear on that site and there is at least one user affiliated at the site which has the Talk Group of interest as their selected channel.  Constraints How the radio is programmed to handle wide area and local sub-system Talk Groups will determine priority Scan capabilities. If the local sub-system Talk Groups is not programmed to the same “system” in the radio, they cannot be included in the priority monitor Scan list. In this case, only Talk Group Scan can be implemented. Priority Scan requires System Infrastructure configuration in order to perform as expected. The Talk Groups that are deemed to be Priority Monitor Groups need to be configured as such by the System Managers. There are practical limitations on the overall number of Priority Monitor Groups that can be enabled due to the amount of time required to distribute the list of active Talk Groups to the radios in real-time. Talk Group Scan does not provide a priority feature to direct the radio to the priority Talk Group. Talk Group Scan can Scan Talk Groups from different systems (as defined in the radio internal programming) and conventional channels. It is strongly recommended that “talkback Scan” not be used. Talkback Scan would direct the user to transmit on the last active Talk Group the radio heard traffic on. This will cause confusion as the radio user will not know what Talk Group the radio will be transmitting on as it will constantly change based upon what the radio last received. Scan is not recommended for those users that must hear critical communications. While Scanning will be available on the systems it will necessarily be limited and, therefore, not be as robust as in conventional radio systems.
