XRT86SH328
28-CHANNEL DS1/E1 FRAMER/LIU WITH DS3 MUX & VT-MAPPER - SONET
JANUARY 2007
REV. P1.0.6
GENERAL DESCRIPTION
The XRT86SH328 is an integrated VT/TU Mapper
with 28 port T1/E1 Line Interface Units. The
XRT86SH328
contains
Framers for performance monitoring.
integrated
DS1/E1/J1
The XRT86SH328 processes the Section, Line and
Path overhead in the SONET/SDH data-stream. The
processing of path overhead bytes within the STS-1s
or TUG-3s include 64 bytes (of buffer) for storing the
(Section Trace and Path Trace) messages. Path
Overhead bytes can be accessed either by on-chip
registers or a Serial Output Port.
Each of the 28 T1 or E1 Channels use an internal De-
Synchronizer circuit with an internal pointer leak
algorithm. This removes the jitter due to mapping and
pointer adjustments from the T1 or E1 signals that are
de-mapped from the incoming SONET/SDH data-
stream. These De-Synchronizer circuits do not need
any external clock references for its operation.
The Transmit Blocks permit flexible insertion of TOH
and POH bytes via both Hardware and Software
control.
The Receive Blocks receive a SONET STS-1 signals
or an SDH STM-1 signal and performs the necessary
Transport and Path Overhead Processing.
A PRBS Pattern Generator and Receiver is
implemented within each of the 28 T1/E1 channels in
order
to
implement
and
performance.

Bit-Error
A general purpose Microprocessor Interface is
included for control, configuration and monitoring.
FEATURES
Provides mapping of up to 28 T1 streams as
Asynchronous VT1.5 into an STS-1 SPE or TU-11
tributary unit into an STM-1/VC-3 or TUG-3 from STM-1/
VC-4
Supports 28 T1 streams M13 multiplexed into a serial
DS3
Supports 21 E1 streams M13 multiplexed into a serial
DS3 (compliant with ITU-T G.747)
28 T1 Streams M13 Multiplexed into a DS3 and DS3 is
asynchronously mapped into STS-1.
21 E1 Streams M13 Multiplexed into a DS3 (ITU-T G.747)
and DS3 is asynchronously mapped into STS-1.
Supports 21 E1 mapped as Asynchronous VT2 into an
STS-1 SPE or TU-12 tributary units into STM-1/VC-3 or
TUG-3 from a STM-1/VC-4.
Supports TU cross-mapping function TU-12/VC-11/T1.
Supports mixed mapping of VT-G/VT1.5 and VT-G/VT2.
Supports mixed mapping of TUG-2/TU-11 and TUG-2/
TU-12
28 VT1.5/TU-11 or 21 VT-2/TU-12 tributaries can be
passed as transparent between SONET/SDH Telecom
Bus on the line side and Clock and Data on the system
side.
Supports Unframed T1/E1 signals
Supports DS1/E1 Performance Monitoring in both Egress
and Ingress direction
VC-11/VC-12 Tandem Connection Monitoring support
Complies
with
the
Category
Requirements for DS1 signals being de-mapped from
SONET, per Telcordia GR-253-CORE
Complies
with
the
"Mapping
Specification" for DS1 and E1 signals being de-mapped
from SDH, per ITU-T G.783
Complies with the "Combined Jitter Generation
Specification" for DS1 and E1 signals being de-mapped
from SDH, per ITU-T G.783
Line and Facility Loop-backs
Each of the 28 T1/E1 Channels includes a PRBS
Generator and Receiver.
Each of the 28 VT-Mapper blocks are capable of
generating BIP-2 and REI errors upon software
command (for diagnostic purposes).
·The Transmit and Receive DS3 Framer blocks support
both the M13(M23) and the C-bit Parity Framing formats.
