122 CHAPTER 3: MULTIFUNCTIONAL INTERFACE MODULESFigure 138 T1 cableFor the pinouts of T1 cables, see Low-End and Mid-Range Series Routers CableManual.c CAUTION: The corresponding cables are not included in the standard shipmentpackage of MIM-2VT1. Please order them together with MIM-2VT1. By default,they are not supplied.Connecting the InterfaceCablec CAUTION:■ You should connect a cable to the port with the correct mark. Misplugging isprone to impair the card and even damage the router.■ When using T1 cable outdoors, you are recommended to install a speciallightning arrester on the input end of the cable in order to avoid lightning moreeffectively.If the MIM has been properly installed, follow these steps to connect the cable:Step 1: Plug one end of T1 cable into the RJ45 connector of MIM-2VT1.Step 2: Connect the other end of T1 cable to the peer device;Step 3: Check the status of LINK LED on the MIM-2VT1 panel: OFF means the linkis not connected. In the latter case, check the line.MIM-1VE1 ModuleIntroduction 1-port E1 voice interface module (MIM-1VE1) can handle dense voice signals inVoIP system.
