LXT6051

STM-1/0 SDH Overhead Terminator

General Description

Features

The LXT6051 Overhead Terminator implements the

Regenerator Section Termination, Multiplexer Section

Termination and Higher Order Path Termination in STM-0

(51Mb/s) and STM-1 (155Mb/s) multiplexers. It provides

micro-controller access for performance monitoring, alarm

detection and configuration for transmit and receive paths.

When used with the LXT6251 (21E1 Mapper), a complete

solution for a 21 E1 or a 63 E1 Multiplexer is created.

• Performs Regenerator Section, Multiplexer Section,

and Higher Order Path Overhead Processing for

STM-1 and STM-0 signals.

• Byte parallel interface for STM-1 or STM-0, with

byte alignment performed internally. Serial NRZ or

B3ZS interface option for STM-0.

• Demultiplexes STM-0/STM-1 signals to Telecom Bus

output with optional pointer processor re-timing.

• Multiplexes Telecom Bus data into STM-0 or STM-1

signals with pointer processing.

The LXT6051 is compliant with the latest releases of ITU-

T G.703 and G.707. It provides all the alarm and control

features to easily implement the multiplexer described in

ITU-T G.783.

• Compatible with 1+1 protected ITU architecture.

• Records all RSOH, MSOH, and HPOH alarms. One

second counters for B1, B2, B3, M1 REI and G1 REI.

• Full J0/J1 trace identifier processing.

Applications

• Serial access to STM-1 user-defined, media-

dependent and national bytes.

• Dedicated pins for serial access or pass-through

feature for E1, E2, F1, F2, F3, D1-D3 & D4-D12

bytes.

• SDH Terminal Mux/ADM for microwave radio

• ADM fiber ring Mux

• Digital Loop Carrier (NGDLC) Systems

• Digital Cross-Connect System

• Low power CMOS technology with 3.3V core and 5V

I/O in PQFP-208 package.

• IEEE 1149.1 Boundary Scan (JTAG) support.
