MIM-1CE3 Module 97
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.
MIM-1CE3 Module
Introduction 1-port channelized E3 interface module (MIM-1CE3) serves to:
■ 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
■ 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.
n
■ 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.
■ The two E3 channels of 2CE3 can work in E3 and CE3 mode respectively.
