FIC-1AE3

Introduction

FIC-1AE3, the 1-port 34 Mbps ATM-E3 interface module, provides these functions:

• Two ATM cell mapping modes: ATM direct mapping (ADM) and physical layer convergence

protocol (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.
