FIC-1AT3

Introduction

FIC-1AT3, the 1-port 44 Mbps ATM-T3 interface module, provides these functions:

• Two ATM cell mapping modes: ADM and PLCP.

• Scrambling in data transmission.

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

• Four types of test measures: local cell loopback, local loopback, remote payload loopback, and

remote line loopback.
