M13 Multiplexer/Demultiplexer

• Provides a generic 8-bit

M23 AND M12 MULTIPLEX/

DEMULTIPLEX SECTIONS

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.

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.

• 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.

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

• Inserts/detects per-DS1 payload

loopback requests transmitted via

C-bits.

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.

APPLICATIONS

• M23 or C-Bit Parity Format DS1 to

DS3 Mux/Demux Equipment

• Fractional T3 Access Equipment

• DS2-to-DS3 Mux/Demux Equipment

• DS1-to-DS3 Mux/Demux Equipment

Supporting G.747 Tributary Format
