7. SPECIFIC GUIDELINES.. 700 MHz Channels For narrowband 700 MHz interoperability, the eight narrowband repeater channels (with direct) described in Figure 4 below will be used. Note the following: . Narrowband 700 MHz interoperability channels are identified by the FCC for interoperability use within Texas. Some of these interoperable channels may already be licensed by multiple agencies for interoperability use throughout the state. . The channels 7CAL59, 7CAL59D are designated as the primary calling channels and 7CAL75, 7CAL75D are designated as the secondary calling channels. All 700 MHz interoperability channels are to be used as multi-discipline, multi-agency public safety interoperability calling channels for all public safety agencies and other signatories to the MOU associated with this channel plan. These channels are designated for interoperable 700 MHz narrowband communications between mobile/portable radios and base stations, temporary base stations and on-incident incident commander. . The tactical repeater channels and direct channels identified in Figure 4 should be assigned on-incident by the incident commander. . Gateways, patching or cross-band repeating of 700 MHz calling channels to calling channels in other bands is not permitted. Patching to/between interoperability tactical channels is permitted during emergency situations if so directed by the incident commander. . Wide implementation of 700 MHz radio systems is not anticipated until approximately 2007 (Some equipment is presently capable of 700/800 MHz operation). Users of this channel plan should anticipate development of additional guidance prior to that time. . This channel plan establishes specific labels for 700 MHz narrowband channels to assure consistency throughout the state and nation. These labels are listed in the Figure 4 and all participating agencies should use these labels.
