Preliminary
OCTAL T1/E1/J1 Short Haul Line Interface Device
PM4319
OCTLIU-SH
FEATURES
• Monolithic device which integrates 8
T1/J1 or E1 short haul line interface
circuits.
• Software-selectable between T1/J1 and
E1 operation on a per-device basis.
• Meets or exceeds T1/J1 and E1 short
haul network access specifications
including ANSI T1.102, T1.403,
T1.408, AT&T TR 62411, ITU-T G.703,
G.704 as well as ETSI 300-011, CTR-
4, CTR-12 and CTR-13.
• Provides encoding and decoding of
B8ZS, HDB3 and AMI line codes.
• Provides clock recovery and line
performance monitoring.
• Provides transmit and receive jitter
attenuation.
• Provides support for redundancy.
• Provides digitally programmable pulse
templates.
• Provides a selectable, per channel
independent de-jittered T1 or E1
recovered clock for system timing and
redundancy.
• Provides PRBS generators and
detectors on each tributary for error

testing at DS1 and E1 rates as
recommended in ITU-T O.151.
• Provides an 8-bit microprocessor bus
interface for configuration, control, and
status monitoring.
• Provides line and digital loopback modes.
• Supports programmable inband
loopback codes.
• Uses line rate system clock.
• Provides an IEEE 1149.1 (JTAG)
compliant test access port (TAP) and
controller for boundary scan test.
• Provides a microprocessor-readable
general purpose input pin and a
microprocessor-writable general
purpose output pin.
POWER
• Implemented in a low power 3.3 V
tolerant 1.8/3.3 V CMOS technology.
PACKAGE
• Available in a high density 288-pin
Tape-SBGA (23 mm x 23 mm) package.
• Provides a -40 °C to +85 °C industrial
temperature operating range.
SYSTEM INTERFACE
• High-density SBI bus interface.
Supports seamless interconnection of
up to 11 OCTLIU-SHs to TE-32,
TEMAP-84 and AAL1gator-32 using
only 27 wires.
RECEIVE SECTION
• Supports T1 signal reception at 772
kHz and E1 signal reception at 1.024
MHz for distances with up to 6 dB of
cable attenuation.
• Performs B8ZS or AMI decoding when
processing a bipolar DS-1 signal, and
HDB3 decoding when processing a
bipolar E1 signal.
• Tolerates more than 0.3 UI peak-to-
peak, high frequency jitter as required
by AT&T TR 62411 and Bellcore TR-
TSY-000170.
• Detects line code violations, B8ZS/
HDB3 line code signatures, loss of
signal, and successive zeroes
conditions.
• Supports G.772 compliant non-
intrusive protected monitoring points.
