Bulletin 383 covered some personnel and historical aspects.
Bulletin 382 briefly touched on the State OES earth-station program (OASIS or Operational Area Satellite Information System) and its 4 trailer-mounted earth stations.
Each of these telephone lines offers five-digit dialing to any other OASIS telephone drop which includes every county in the state as well as other locations. It also provides access to the Public Switched Telephone Network (PSTN) through redundant access points. An interface from OASIS to a state microwave phone network is also possible.
These mobile units have self-contained power or can use 2 110-volt 20-amp circuits when available for 'shore' power. Because they communicate on microwave frequencies with a satellite, an unobstructed view in a designated path and elevation is needed.
Two other aspects of OES communications resources include these: A mobile trailer mounted alternate earth-station hub capable of 48 voice lines, 2 data lines. It was recently deployed and supported by ACS field personnel at the Marks-Nielsen fire in Central California.
There are almost 800 handheld radio on VHF Hi, UHF (both 450-470 and 470-490 MHz) and 800 MHz NPSPAC. These are available as non encrypted radios in caches for fire, law and emergency services located statewide, for those agencies if requested under the mutual aid system of government helping government. (See more on mutual aid on the California State OES Web Site.)
So, from these frequencies and equipment, we see that these Public Safety communications units are quite different than Communications Vans intended to primarily provide Amateur Radio frequency coverage. Abbreviations used: CHP: CA Highway Patrol; CDF: CA Department of Forestry; ICP: Incident Command Post; CMARS: California Mutual Aid Radio Systems; CESRS: California Emergency Services Radio System.
Series continues next bulletin which describes eight additional rolling-stock units on truck or motor home chassis for Fire agency response and Law Enforcement situations based on mutual aid requests.
