CPI MCR220 Tone Remote and Termination Box?

[Markup]

First post, brand new so please bear with me. I was recently given a CPI MCR220 tone remote and my intent is to use it with a VHF GM300. My understanding is this remote needs an MCP200 termination panel to interface with the radio, although it didn't come with one. I'd like to know more about the background and vintage of this equipment, the basic elements of it's operation, etc. And, if anyone has any further insight or sourcing for a termination panel, that would be as greatly appreciated.

Thanks for your time!

The MCP200 is also know as a tone remote adapter. It is available from TESCO and other radio accessories distributors. It is essentially a device that converts the control signals in the radio to tones that can be sent down dedicated 2 or 4 wire type phone lines to the tone remote (i.e desk set). It also sends the TX and RX audio as well. The tone remote connects to the radio through the radios accessory socket. It can control the channel selector as well as other radio front panel functions. The phone lines can be in house or dedicate phone company lines. Other types of transmission mediums can be used with the appropriate interfaces.

Thanks! I got in touch with CPI and they still have a few MCP200G termination panels laying around. I've purchased mine and it's supposedly on the way.
