Loopback Functions of Various Boards for the Metro SDH Products

Overview

Due to previous design or chip specification bugs, some boards for the Metro SDH products do not support some loopback settings, which can impact the field test and problem location to some extent.

This document describes how all boards for current Metro SDH products support all kinds of loopback functions to guide engineers for engineering test, problem location and query.

Introduction to Loopback

Classification

Currently, loopback for the SDH products is classified into port loopback and path loopback. Port loopback is further classified into STM-N optical port loopback/electrical port loopback, electrical port loopback on the tributary board, and external optical port/electrical port loopback on the Ethernet board. Path loopback is further classified into VC4 loopback, VC3 loopback, and VC12 loopback. For all optical network products, the loopback is cross-connect board centered. If the signal flow is looped back to the cross-connect board, the loopback is an inloop; if the signal flow after loopback is not to the cross-connect board, the loopback is an outloop.

Precautions on Loopback

1. The first VC4 loopback of most line boards for the SDH products may impact ECC communication.

2. Most boards for the SDH products support automatic loopback release. However, some NEs disable the function by default, and some enable

it. The “:cfg-get-autoclear” command line is used to query automatic loopback release.
