By design, the FIC-1CE3 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-1CE3 and the other 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-1CE3 and the other end
to the Tx port on another device.
Step3 Power on the router, and check the behavior of the LINK LED on the FIC-1CE3 panel: OFF means
fault occurs on the line and the signal is not synchronized. Check the line status.
FIC-1CT3
Introduction
FIC-1CT3, the 1-port channelized/non channelized T3 interface module, delivers these functions:
z
In T3 mode, transmitting, receiving, and processing one channel of T3 fast traffic; providing T3
traffic access.
z
In CT3 mode, providing the subscribers with N × 64 kbps or N × 56 kbps low-speed access, where
N is smaller than or equal to 128.
T3 represents the tertiary group rate of T system in the TDM system, that is, 44.736 Mbps. Through T23
and T12A demultiplexing, a T3 channel can be channelized into 28 T1 lines, each also supporting the
operating mode of CT1. T23 means either T2-to-T3 multiplex or T3-to-T2 demultiplex, and T12 means
T1-to-T2 multiplex or T2-to-T1 demultiplex. “T23” and “T12” discussed here represent the demultiplex
process.
