Connecting the interface cable
By design, the FIC-1AE3 is protected against lightning strikes. But when outdoor cabling is involved,
you are recommended to add a special lightning arrester at the input end of the E3/T3 cable for better
protection.
Step1 Connect the SMB connector of an E3/T3 cable to the Tx port on the FIC-1AE3 and another end to the
Rx port on another device.
Step2 Connect the SMB connector of another E3/T3 cable to the Rx port on the FIC-1AE3 and another end
to the Tx port on another device.
Step3 Check the behavior of the LINK LED on the FIC-1AE3 panel: OFF means fault occurs on the line and
the signal is out of synchronization. Check the line status.
FIC-1AT3
Introduction
FIC-1AT3, the 1-port 44 Mbps ATM-T3 interface module, provides these functions:
z
Two ATM cell mapping modes: ADM and PLCP.
z
Scrambling in data transmission.
z
Line clock (when working as DTE interface) and internal clock (when working as DCE interface).
z
Four types of test measures: local cell loopback, local loopback, remote payload loopback, and
remote line loopback.
You may equip your router with FIC-1AT3 modules to its full capacity. Yet, you are recommended to
install only one FIC-1AT3 on it, whatever its model is, to ensure performance of some key services.
