A 384-kbit/s ISDN burst transceiver

An Integrated Services Digital Network (ISDN) burst transceiver circuit is described which provides two-wire data transmission using the time-compression multiplexing technique and an AMI (alternate mark inversion) line code at a line bit rate of 384 kb/s. An automatic line equalizer handles a wide variety of twisted pair cable types including highly capacitive cables with up to 32-dB insertion loss at the Nyquist frequency.
