Octal E1 Framer
FEATURES
Monolithic single-chip device that
integrates eight datacom E1 framers
and transmitters for terminating duplex
E1 signals.
Frames to ITU-T G.704 basic and
CRC-4 multiframe formatted E1
signals and is consistent with ITU-T
G.706 specifications.
Extracts/inserts up to three HDLC links
from/to arbitrary time slots to support
the D-channel for ISDN Primary Rate
Interfaces, the datalink in the National
Use Bits and the C-channels for V5.1/
V5.2 interfaces as per ITU-T G.964,
ITU-T G.965, ETS 300-324-1, and
ETS 300-347-1.
Provides an optional backplane
interface which is compatible with Mitel
ST
-bus, AT&T CHI
and MVIP PCM
backplanes, supporting data rates of
2.048 Mbit/s and 8.192 Mbit/s.
Supports transfer of PCM data to and
from 2.048 Mbit/s backplane buses.
Supports fractional E1 backplane
interface.
Provides jitter attenuation in both the
receive and transmit directions.
Provides per-timeslot line loopback
and per-link diagnostic and line
loopbacks.
Provides signaling extraction and
insertion on a per-channel basis.
Provides a Pseudo Random Binary
Sequence (PRBS) generator and
detector which may be configured for
insertion/detection on a per-timeslot or
multiple timeslot basis.
Software-compatible with the PM6341
E1XC Single E1 Transceiver, the
PM6344 EQUAD Quad E1 Framer, the
PM4388 TOCTL Octal T1 Framer, and
PM4351 COMET Combined E1/T1
Transceiver.
Pin-compatible with the PM4388
TOCTL with a seamless interface to
the PM4314 QDSX quad line interface
unit.
Provides an 8-bit microprocessor bus
interface for configuration, control, and
status monitoring.
Low power 3.3 V CMOS technology
with 5 V tolerant inputs.
Supports standard 5-signal P1149.1
JTAG boundary scan.
Provides a -40 to +85
°
industrial
temperature operating range.
Available in a rectangular 128-pin
PQFP (14 by 20 mm) package.
RECEIVE SECTION
Red and AIS alarm detection and
integration are done according to
ITU-T Q.516 specifications.
Can be programmed to generate an
interrupt on change of signaling state.
Provides performance monitoring
counters sufficiently large as to allow
performance monitor counter polling at
a minimum rate of once per second.
Accumulators are provided for
counting ESF CRC-6 errors, framing
bit errors, Far-End Block Errors
(FEBEs) and PRBS bit errors.
Provides a 2-frame buffer for jitter and
wander attenuation.
TRANSMIT SECTION
Transmits G.704 basic and CRC-4
multiframe formatted signals with
support for unframed mode.
May be timed to its associated receive
clock (loop timing) or may derive its
timing from a common egress clock or
a common transmit clock; the transmit
line clock may be synthesized from an
n
×
8kHz reference.
Provides a digital PLL for generation of
a low jitter transmit clock.
Provides a FIFO buffer for jitter
attenuation and transmit rate
conversion.

multiplexers, switches, routers, and
digital modems
