MIM-1AT3 Module 109Step 2: Connect the SMB connector of another E3/T3 cable to the Rx port ofMIM-1AE3 module and another end to the Tx port on the device to be connected;Step 3: Check the behavior of the LINK LED on the MIM-1AE3 panel. It is OFFwhen fault has occurred on the link and signal is out of synchronization. In thiscase, please check the link.MIM-1AT3 ModuleIntroduction 1-port 44.736 Mbps ATM-T3 interface module (MIM-1AT3) supports:■ Two ATM cell mapping modes: ADM and PLCP;■ Scrambling in data transmission;■ Both line clock (when working as DTE interface) and internal clock (whenworking as DCE interface);■ Four types of test measures, i.e., local cell loopback, local payload loopback,remote payload loopback, and remote line loopback.n You are allowed to equip an H3C Series Router with MIM-AT3 modules to its fullcapacity. Yet, you are recommended to install only one MIM-AT3 module on it,whatever its model is, to ensure the performance of some key services.Interface Attributes The interface attributes of MIM-1AT3 are given in the following table:n In the supported services described in the above table, CBR represents ConstantBit Rate, rt_VBR represents Variable Bit Rate-Real Time, nrt_VBR representsVariable Bit Rate-Non Real Time, and UBR represents Unspecified Bit Rate.Interface LEDs MIM-1AT3 panel is shown in the following figure:Figure 122 MIM-1AT3 panelThe following table describes the LEDs on the MIM-1AT3 panel:Table 69 Interface attributes of MIM-1AT3 moduleAttribute 1AT3 ModuleConnector SMBConnector number 2Interface standard G.703, G.704, G.823Interface rate 44.736 MbpsCable E3/T3 cable (75-ohm coaxial cables)Supported service ATM Traffic CBR, rt_VBR, nrt_VBR, UBR
