BLOCK DIAGRAM
FEATURES
Monolithic single chip device which
integrates a full featured T1 framer
with an on-chip analog line interface.
Supports SF, ESF, T1DM (DDS) and
SLC96 format DS1 signals.
Supports unframed mode. Supports
B8ZS or AMI line codes.
Recovers clock and data from the
incoming DSX-1 signal, generates
DSX-1 output signal.
Supports transfer of PCM and
signalling to/from 1.544 Mbit/s and
2.048 Mbit/s backplane buses.
Supports gapped data streams used
in higher rate multiplexing.
Provides robbed bit signalling
insertion/extraction, idle code
substitution, digital milliwatt code
substitution, data inversion and 2
superframes of signalling debounce
on a per channel basis.
Pin compatible with the PM6341
E1XC E1 Transceiver.
Software compatible with the
PM4344 TQUAD Quad T1 Framer
and PM4388 TOCTL Octal T1
Framer.
Provides an 8-bit microprocessor bus
interface for configuration, control
and status monitoring.
Low-power 5V CMOS technology.
Avalable in a high density 80-pin (14
by14mm) PQFP or in a 68-pin PLCC
package.

SLC96 is a registered trademark of AT&T
RECEIVE SECTION
Provides loss of signal, red alarm,
yellow alarm and AIS alarm
indication. Detects violations of the
ANSI T1.403 12.5% pulse density
rule over a moving 192 bit window.
Supports line and path performance
monitoring per Bellcore, AT&T and
ANSI recommendations.
Accumulators are provided for ESF
CRC-6 and framing bit errors, Line
Code Violations and Loss Of Frame
or Change Of Frame Alignment
events.
Extracts the data link in ESF, T1DM
and SLC96 formats. Extracts the
D-channel for primary rate interfaces.
Provides ESF bit-oriented code
detection and an HDLC interface for
terminating the ESF datalink.
Provides a 2 frame elastic store for
jitter and wander attenuation.
Detects programmable in-band
loopback codes.
TRANSMIT SECTION
Provides per channel minimum ones
density through Bell (Bit 7), GTE or
DDS zero code suppression.
Detects violations of the ANSI T1.403
12.5% pulse density rule over a
moving 192 bit window.
Inserts the data link in ESF, T1DM
and SLC96 formats. Inserts the D-
channel for primary rate interfaces.
Generates AIS and yellow alarm in
all formats.
Inserts the data link in ESF, T1DM
and SLC96 formats. Inserts the D-
channel for primary rate interfaces.
Generates ESF bit-oriented codes
and provides an HDLC interface for
generating the ESF datalink.
Inserts programmable in-band
loopback codes.
Provides a FIFO buffer for jitter
attenuation and rate conversion.
