Step3 Check the behavior of the LINK LED on the FIC-1AT3 panel: OFF means fault occurs on the line and

the signal is out of synchronization. Check the line status.

FIC-1ATM-OC3

Introduction

FIC-1ATM-OC3 is short for 1-port ATM 155 Mbps optical interface module.

FIC-1ATM-OC3 provides the following functions:

z

Two frame formats: SDH STM-1 and SONET OC-3.

z

Scrambling in data transmission.

z

Line clock (when working as DTE interface), and internal clock (when working as DCE interface)

z

Three test measures: local cell loopback, local payload loopback and remote loopback.

For the ATM interface configuration procedures, see H3C MSR Series Routers User Manual.
