Pay Phone

Typical 1990’s Protel COCOTS coin-phone.

Coin-op guts have been removed and replaced with electronics from an armored “jail” phone, and the bell ringer from a modern Coretelco 2554.

I run an Avaya Definity G3siV9 PBX (Link to my Vintage technology museum site) which provides this payphone (and all my other vintage telephones) with their dial-tone.
