Step 2: Connect one RJ-45 connector at the other end of the cable to the device to be
connected.
Step 3: Power on the router. Check the behavior of the LINK LED on the module panel.
It is OFF when fault has occurred on the link and signal is out of synchronization. In this
case, please check the link.
3.10 MIM-1CE3 Module
3.10.1 Introduction
1-port channelized E3 interface module (MIM-1CE3) serves to:
z
Transmit/Receive and handle one channel of E3 fast traffic, as well as provide the
accessing of E3 traffic when working in E3 mode; and
z
Provide the low-speed accessing service at the speed of n × 64 kbps, where n is
smaller than or equal to 128, when working in CE3 mode.
Note:
z
E3 represents the tertiary group rate of E system in the TDM system, that is,
34.368Mbps. An E3 channel can be channelized into 16 E1 lines through the
demultiplexing processes of E23 and E12, each E1 line supporting both the
operating modes of E1 and CE1. E23 is used to indicate either E2-to-E3 multiplex or
E3-to-E2 demultiplex, and E12 to indicate E1-to-E2 multiplex or E2-to-E1
demultiplex. “E23” and “E12” discussed here represent the demultiplex process.
z
The two E3 channels of 2CE3 can work in E3 and CE3 mode respectively.
