FIC-1ATM-OC3
Introduction
The 1-port ATM 155 Mbps optical interface module (FIC-1ATM-OC3) provides the following features:
• 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.

LINK/ACT
• On means carrier signal has been received.
• Flashing means data is being received or/and transmitted.
• Off means no carrier signal has been received.
LP/AL
• On means the interface is in a loopback.
• Flashing means an AIS, LFA, or RAI alarm signal is present.
• Off means no loopback or alarm is present.
Note:
LFA = Loss of frame alignment; AIS = Alarm indication signal; RAI = Remote alarm indication.
