XRT72L13
M13 MULTIPLEXER/CLEAR CHANNEL DS3 FRAMER IC
APRIL 2001
REV. P1.0.6
GENERAL DESCRIPTION
The XRT72L13 is a fully integrated, low power, Multi-
plexer/Framer IC which performs Multiplexing/De-
mutiplexing of 28 DS1or 21 E1 signals into/from a
DS3 signal with either M13 or C-bit parity frame for-
mat, performs Clear Channel DS3 Framing, and sup-
ports High speed HDLC/LAPD data linking.
The XRT72L13 also contains M12 and M23 bit-inter-
leaving multiplexing/demultiplexing functions with
necessary stuffing and destuffing control. Seven in-
ternal 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 Er-
ror Accumulation in accordance with ANSI/ITU-T
specifications.
The XRT72L13 provides the intelligent functions of
DS3/DS2 mode control, signaling control, error and
alarm reporting and handles the HDLC/LAPD data
link through internal registers accessible via an 8-bit
parallel, memory mapped, µProcessor interface.
