FIC-1AE3
Introduction
The 1-port 34 Mbps ATM-E3 interface module (FIC-1AE3) provides the following features:
• 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.
