Connecting the interface cable
Step1 Insert the DB-68 connector of the 4T1/8T1 conversion cable to the DB-68 port on the
FIC-IMA-4T1/FIC-IMA-8T1 module.
Step2 Connect one RJ-45 connector at the other end of the cable to the peer device to be connected.
Step3 Power on the router. Check the behavior of the LINK LED on the module panel: OFF means the line
has problem. Check the line status in this case.
FIC-1AE3
Introduction
FIC-1AE3, the 1-port 34 Mbps ATM-E3 interface module, provides these functions:
z
Two ATM cell mapping modes: ATM direct mapping (ADM) and physical layer convergence
protocol (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-1AE3 modules to its full capacity. However, you are recommended
to install only one FIC-1AE3 on it, whatever its model is, to ensure performance of some key services.
