DC Signaling Devices

The M-959 is a low-power dial pulse Counter and hook status monitor. Contained in a 14-pin package, the M-959 requires no external components except a single 3.579 MHz Television color burst crystal. The M-959 is typically connected to a loop current sensing circuit, which is connected in series with the voice pair (Tip and Ring) of a telephone line. The M- 959 receives pulses from the loop Current Sense cir- cuit and translates them into Logic level outputs indicating hook status and decoded dialed digits. Logic inputs to the M-959 select dialed digit speeds and control Data and Strobe outputs supporting bus interrupt driven implementations. By Clare, Inc.
