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, the FSK modulated data containing
information on the calling line is sent before alerting
the called party or during the silent interval between
the first and second ring using either CCITT V.23
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 Office. The received data can be
processed externally by a microcontroller, stored in
memory, or displayed as is, depending on the
application.
