M13 Multiplexer/Demultiplexer
FEATURES
Integrates a complete M13 multiplexer/
demultiplexer in a single monolithic
device.
Integral framer supports the M23 or C-
bit parity DS3 format with path
maintenance datalink processing and
bit-oriented code support for Far-End
Alarm and Control (FEAC) channel
termination.
Supports either the M12 or the G.747
formats to allow DS1 or E1 signals to
be multiplexed into a DS3 signal.
Allows the M12 stages to be bypassed
allowing direct input of DS2 signals.
Generates an interrupt upon detection
of various alarms, events, or changes
in status. Identification of interrupt
sources, masking of interrupt sources,
and acknowledgement of interrupts is
provided via internal registers.
Application-compatible with the
PM4351 COMET T1 Transceiver,
PM4341A T1XC T1 Transceiver,
PM4344 TQUAD Quad T1 Framer,
PM4388 TOCTL Octal T1 Framer,
PM6341 E1XC E1 Transceiver,
PM6344 EQUAD Quad E1 Framer,
PM6388 EOCTL Octal E1 Framer,
PM4314 QDSX Quad E1/T1 LIU, and
the PM7344 S/UNI
-MPH.
Provides a generic 8-bit
microprocessor interface for
configuration, control, and status
monitoring.
Low power 5 V CMOS technology.
Available in a high density (28 by
28 mm) 208-pin Plastic Quad Flat
Pack (PQFP) package.
DS3 FRAMER SECTION
Detects/inserts DS3 Alarm Indication
Signal (AIS) and Idle signal - operates
correctly in the presence of 10-3 Bit
Error Ratio (BER).
Extracts/inserts the X,P,M,F,C and the
stuff opportunity bits and serializes for
optional external processing.
Extracts/inserts the C-bit parity mode
path maintenance datalink and
serializes for optional external
processing.
Extracts/inserts the C-bit parity bit-
oriented codes in the FEAC channel.
Detects and accumulates EXcessive
Zeros (EXZ), Loss Of Signal (LOS),
Line Code Violations (LCVs) P-bit,
F-bit, or M-bit errors, C-bit parity errors
and Far-End Block Errors (FEBEs).
Supports DS3 line loopback and DS3
diagnostic loopback modes to assist in
fault isolation.
M23 AND M12 MULTIPLEX/
DEMULTIPLEX SECTIONS
Supports combination of four DS1 bit
streams or the combination of three E1
bit streams per G.747 into a single
M12 stream.
Supports per-DS2 payload loopback
requests via C-bits or microprocessor
control.
Accumulates DS2 M-bit, F-bit, and
G.747 framing bit/word error events.
Supports DS2 AIS assertion based on
DS3 LOF, or under microprocessor
control.
Supports DS2 tributary AIS activation/
deactivation in either direction under
microprocessor control.
Inserts/detects per-DS1 payload
loopback requests transmitted via
C-bits.
