Hey all, I came across this telephone interface unit that is ancient, called a Mccurdy TIM-940. So old, the company doesn't even have a website. It has telco input, via a banana plug. Anyone have any idea what this is? I would expect an intercom interface to have like.. an RJ14 input.
Dunno about the Telco connection, but Google reckons the TIM-940 is a Tone Activated Switcher. Have a trawl through this for some info.
From what I can find, Telco connections are aka RJ-21, can't find any pics but they're Half Parrallel, 25 pins. Not banana plugs...
