4.10.1 Introduction

Three ATM fiber interface card options are available with your router:
1-port ATM 155 Mbps multi-mode fiber interface card (ROUTER 1-PORT OC-3
ATM MM FIC)
1-port ATM 155 Mbps single-mode fiber interface card (ROUTER 1-PORT OC-3
ATM SM FIC)
1-port ATM 155 Mbps single-mode long-haul fiber interface card (ROUTER

1-PORT OC-3 ATM SML FIC)

They provide the following functions:
Two frame formats: SDH STM-1 and SONET OC-3.
Scrambling in data transmission.
Line clock (when working as DTE interface), and internal clock (when working as
DCE interface)
Three test measures: local cell loopback, local payload loopback and remote
loopback.
