3Com Router 5000 and Router 6000 v2.41Module GuideChapter 3Multifunctional Interface Modules (Router 5000)3-602) Connect one RJ45 connector of the Router 4-Port T1 IMA MIM conversion cableto a peer device.3) Check the status of the LINK LED on the panel of the Router 4-Port T1 IMA MIMinterface card. If the LED is off (indicating the line is faulty), check the line.3.16 Router 1-Port CE3 MIM Module3.16.1 Introduction1-port channelized E3 interface module (Router 1-Port CE3 MIM) serves to:z Transmit/Receive and handle one channel of E3 fast traffic, as well as provide theaccessing of E3 traffic when working in E3 mode; andz Provide the low-speed accessing service at the speed of n x 64 kbps, where n issmaller than or equal to 128, when working in CE3 mode.Note:E3 represents the tertiary group rate of E system in the TDM system, that is, 34.368Mbps. An E3channel can be channelized into 16 E1 lines through the demultiplexing processes of E23 and E12, eachE1 line supporting both the operating modes of E1 and CE1. E23 is used to indicate either E2-to-E3multiplex 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.3.16.2 Interface AttributesThe interface attributes of Router 1-Port CE3 MIM are given in the following table:Table 3-38 Interface attributes of Router 1-Port CE3 MIMAttribute DescriptionConnector SMBNumber of connectors 2Interface standard G.703, G.704, G.751Interface rate 34.368MbpsInterface cable type E3 cable (75ohm coaxial cable)Operating mode E3CE3Services supported E3 leased line
