    áç APRIL 2001 PRELIMINARY XRT72L13 REV. P1.0.6 M13 MULTIPLEXER/CLEAR CHANNEL DS3 FRAMER IC GENERAL DESCRIPTION The XRT72L13 is a fully integrated, low power, Multiplexer/Framer IC which performs Multiplexing/Demutiplexing of 28 DS1or 21 E1 signals into/from a DS3 signal with either M13 or C-bit parity frame format, performs Clear Channel DS3 Framing, and supports High speed HDLC/LAPD data linking. The XRT72L13 also contains M12 and M23 bit-interleaving multiplexing/demultiplexing functions with necessary stuffing and destuffing control. Seven internal DS2/G.747 framers are included to support Mux/Demux purposes. The XRT72L13 contains an integral DS3 Framer which provides Clear Channel DS3 Framing and Error Accumulation in accordance with ANSI/ITU-T specifications.
