The primary purpose is to allow the use of more than one tone/code on
the same system. This is all earlier tone panels would do.
Secondary purposes, usually reserved for newer panels, include usage
counts, CW identifiers, and remote control, either DTMF over the air, or
by RS-232/modem.
Your TKR-850 will do just fine as long you don't care about usage stats
or remote control (I'm not too familiar with the -850 to know it's
capabilities, but the -820 was just a basic 8-tone board with
time-out-timer, no other functions.)
