CML MX613
The MX613 is a wide-band, ‘N-Tone’ non-predictive tone decoder that measures telephone system call progress tones in PABX, Pay/Feature-Phone, Fax and Modem systems. The result of each measurement is presented to a system µProcessor as a 6-bit serial word. The decode frequency range, which covers the world's call progress application spectrum, is processed internally as two bands: LO = 300 to 660Hz and HI = 900 to 2150Hz.| Part No. | MX613 |

Frequency measurement is achieved by counting the number of cycles in a set time period (LO = 39.47ms or HI = 13.16ms).
