[SML] ClearComm questions

[Steven Santos]

I have a couple of ClearComm questions for those in the group.

Theater in the planning stages.

1. When pre-wiring a space for CC audio, what wire should be used?
  18g?  20g?  4 wire or 5 wire?


2. Many years ago I saw a CC system that interfaced with the schools
PBX system. From any phone in the building so programmed, you could
hit one of the two CC lines and be connected in to the CC channel.
Anyone know what this device is?


3. I have found devices to connect a CC system to half duplex 2-way
radios.  Does anyone know if such a device exists for full-duplex
2-way radios?
