Brief Description
The FX663 decodes the standard audible tone signals provided by telecom systems worldwide to indicate Dial,
Ringing, Busy, Unobtainable and other stages of a call attempt. It provides the key features needed for
intelligent, full-function, call progress monitoring by applications involving machine dialling or automatic call
placement. The FX663 also incorporates the following features:

Single and dual tone decoding for better cross-system Call Progress monitoring.
"US Busy" tone detector, saving time needed for "cadence verification" under Busy and Unobtainable
conditions. This incorporates a separate 620Hz detector for improved response.
A detector to indicate speech and non-call progress signals; this reduces voice falsing of call progress
tones and adds Voice-Answer detection as a "connected" prompt.
A fax and modem tone decoder.
A separate, adjustable threshold, signal-level detector which reduces noise falsing.
The FX663 uses new digital signal processing techniques to provide these advantages. It is a low cost, low
power product with superior performance. It is available in industry standard 16-pin packages.
