Chapter 5 - Diagnostics and Loopback Functions

5-1 General Information

This chapter contains detailed information on the diagnostics and the loopback tests of
the FMUX03 fiber optics transmission equipment. User can activate the loopback
function to diagnose the full service.

5-2 Loopback Functions for E1 Tributary

There are two types of loopback functions for the E1 Module: Local Loopback and
Remote Loopback. User can select whether to diagnose a specific channel or all
channels under the “E1 Configurations” options.

Figures below illustrates the concepts of the loopback function:

Local Side Loopback:

Local Side Loopback tests the path between local E1 and remote E1.
