Description
The M-980-02 is an integrated circuit tone detector for
general purpose use in automatic following of switched
telephone calls. The circuit uses low-power CMOS
techniques to provide the complete filtering and control
required for this function. The basic timing of the M-
980-02 is designed to permit operation with almost any
progress tone system.
The use of integrated circuit techniques allows the
M-980-02 to pack the complete frequency and ampli-
tude portion of call progress following into a single 8-
pin DIP or 16-pin SOIC. A 3.58 MHz crystal-controlled
time base guarantees accuracy and repeatability.
3V/5V operation increases customer flexibility,
improves reliability, and minimizes power consump-
tion.

... Drop-outs of valid tone will be ignored. B Note: Application or removal of high level signals outside the must detect range may cause momentary detection, which may be filtered by time guarding the output. Rev times per minute (60 IPM). The tones can be dis- tinguished in this way. It should be noted that while such techniques will usu- ally be effective, there are some circumstances in which the M-980-02 cannot be accurately used ...
