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.
