Description
The MT88E41 Extended Voltage Calling Number
Identification Circuit (ECNIC) is a CMOS integrated
circuit providing an interface to various calling line
information delivery services that utilize 1200 baud
BELL 202 or CCITT V.23 FSK voiceband data
transmission schemes. The ECNIC receives and
demodulates the signal and outputs data into a simple
3-wire serial interface.
Typically,
information on the calling line is sent before alerting the
called party or during the silent interval between the first
and
second
ring
using
recommendations or Bell 202 specifications.

The ECNIC accepts and demodulates both CCITT V.23
and BELL 202 signals. Along with serial data and clock,
the ECNIC provides a data ready signal to indicate the
reception of every 8-bit character sent from the Central
