co-channel operations at separate incidents and venues may be conducted if effective radiated power is limited to the minimum level required to maintain reliable communications at each incident. Because FCC frequency re-farming has established new narrowband channels adjacent to existing wideband channels, interference from properly licensed adjacent channel users is possible. If interference to the interoperability channels from licensed users (who are signatory to this plan) occurs during an incident, those users should consider their communications to be secondary to emergency interoperability traffic on the interoperability channels. On-channel and adjacent channel interference issues during an incident or event must be resolved by the incident commander. The Texas Department of Public Safety, RF Unit, should be immediately be notified of interference to the interoperability channels in order to assist in resolution of the problem. Calling Channels Initial radio contact during travel to or arrival at an emergency incident may be established on an appropriate interoperability calling channel. · Calling channel communications shall use non encrypted analog FM emissions, with the widest allowable bandwidth per current FCC regulations. Exception: 700 MHz calling channel must utilize Project 25 Phase 1 Common Air Interface (CAI). . If a region, or an adjacent region, has wideband VHF users, Texas Law 2 should be continually monitored by appropriate dispatch points within the affected regions until those users substantially complete conversion to either narrowband VHF or another channel band. At a time to be identified in the regional interoperability plan, Texas Law 2 monitoring should be augmented by or converted to the narrowband VHF channel VCALL. Note the conversion date of January 1, 2008 identified in the MOU associated with this channel plan. · If a region, or an adjacent region, has wideband UHF users, a regionally identified wideband UHF channel should be continually monitored by appropriate dispatch points within the affected regions until those users substantially complete conversion to either narrowband UHF or another channel band. These wideband UHF channels must be licensed separately and are not covered by this plan. At a time to be identified in the regional interoperability plan, wideband UHF monitoring should be augmented by or converted to the narrowband UHF channel UCAlL. · If a region, or an adjacent region, has jurisdictions that use or plan on using 700 MHz equipment, the channel 7CAL59 should be continually monitored by appropriate dispatch points within the affected regions when those users are substantially converted to 700 MHz. At a time to be identified in the regional interoperability plan, any existing interoperability channel monitoring should be augmented by or converted to the channel 7CAL59 within the affected regions. · If a region, or an adjacent region, has 800 MHz users, the 800 MHz channel BeAll should be continually monitored by appropriate dispatch points within the affected regions. Monitoring of VHF wideband channel Texas Law 2 (formerly known as "Intercity") is wide-spread throughout the state. Monitoring of the 800 MHz NPSPA channels is common is the metro areas as well. The TSIEC suggests that regional interoperable communication plans recognize and address the monitoring capabilities that will be needed within their jurisdictions in order to assure interoperability among public safety users. For some regions, monitoring VHF and 800 MHz calling channels may be adequate. Other regions may need to monitor additional interoperability channels in order to assure that interoperability is achieved. 6
