attenuated 8 dB or better, and is close to talkoff

compliant even without near end speech attenuation

Description

The MT88E46 is a CMOS integrated circuit suitable for

receiving the FSK and CAS signals in North American

(Bellcore) CIDCW, CWD and CID (Calling Identity

Delivery) services. It provides an optimal solution for the

CIDCW (also known as Type 2) and CWD (Type 2.5)

telephone set applications by providing separate input op-

amps for Tip/Ring and 4-wire side (receive pair of the

telephone hybrid or speech IC) connections. The Tip/Ring

connection is compatible with TIA’s MEI scheme and can

be used for FSK demodulation and ‘on hook mode’ CAS

detection. The 4-wire side connection is for ‘off hook

mode’ CAS detection. The CAS detection modes - on

hook and off hook - use different algorithms which are

optimized for the CPE states. In ‘off hook mode’ the CAS

detector is Bellcore compliant when near end speech is

attenuated 8dB or better. ‘On hook mode’ is optimized for

talkdown only and typically meets talkdown condition 1

(the average case) without speech attenuation at Tip/Ring

such as in the on hook state MEI CPE.
