PCMTIM telephone interface module incorporates a universal interface so that connection to any telephone system is rapid and trouble-free.The module connects to the telephone system via a standard RJ11 plug and is programmed simply by using common DIP switches. All other connections are made to built-in terminal blocks using only a small screwdriver. Setup is also easy. Zone group programming, selection of all signaling functions, and all other parameters are set by simply dialing in with a touch-tone telephone. The telephone interface module is equipped with three RJ11 jacks for Night Ring, Tel Line, and Override. The NIGHT RINGER feature can be activated from 90V ring signal or contact closure. The TEL LINE jack can be used to program the system locally and provides 48V talk battery. The OVERRIDE feature permits all-zone override paging from a dedicated telephone, trunk, or microphone (with suitable pre-amp).
