描述 Description

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.Features Provisional Issue
