W925E/C625
8-bit CID Microcontroller
6.16 Calling Identity Delivery (CID)
Revision : A6
-52-
Release Date : 2002/7/2
W925E/C625 provides type I and type II of CID system. Type I is on-hook calling with CID
message and type II is off-hook call on waiting. The CID function includes FSK decoder, dual
tone alert signal detector, ring detector and DTMF receiver. The FSK demodulation function can
demodulate Bell 202 and ITU-T V.23 Frequency Shift keying (FSK) with 1200 baud rate. The
Tone Alert Signal detect function can detect dual tones of Bellcore Customer Premises
Equipment(CPE) Tone Alerting Signal(CAS) and BT Idle State and Loop State Tone Alert Signal.
The line reversal for BT, ring burst for CCA or ring signal for Bellcore can be detected by ring
detector. It is compatible with Bellcore TR-NWT-000030 & ST-TSV-002476, British Telecom(BT)
SIN227, U.K. Cable Communications Association(CCA) specification.
The DTMF receiver can be
programmed as DTMF decoder to decode 16 DTMF signals or tone detector to detect the signal
which frequency is in DTMF band. The tone detector can be an auxiliary detector to improve the
performance of detecting tone alerting signal(CAS), said as talk down-off, in type II system.
The FSK decoder, alert tone detector and DTMF receiver can be enable/disable individually by
the bits of FSKE, CASE and DTMFE in FSK DATA REGISTER(FSKDR). CIDE is the global
control bit to enable/disable FSK decoder, alert tone detector and DTMF receiver. However, the
ring detector is always active.
