73MIM-1CE3IntroductionThe 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 ofE3 traffic when working in E3 mode.• Provide the low-speed accessing service at the speed of n No 64 kbps, where n is smaller thanor equal to 128, when working in CE3 mode.NOTE:E3 represents the tertiary group rate of E system in the TDM system, that is, 34.368 Mbps. An E3channel 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 eitherE2-to-E3 multiplex or E3-to-E2 demultiplex, and E12 to indicate E1-to-E2 multiplex or E2-to-E1demultiplex. "E23" and "E12" discussed here represent the demultiplex process.Interface specificationsTable 99 Interface specificationsItem DescriptionConnector SMBNumber of connectors 2Interface standard• G.703• G.704• G.751Interface rate 34.368 MbpsInterface cable type E3 cable (75ohm coaxial cable)Operating mode E3CE3Supported service E3 leased lineInterface LEDsFigure 80 MIM-1CE3 panelTable 100 LED descriptionLED DescriptionLINK • Off: The link is not set up.• On: The link has been set up.
