38 CHAPTER 3: INTRODUCING ROUTER 5000 F AMILY MIM SPower off the router before plugging or unplugging the 1-to-4 conversion cable,as well as the serial cables, to avoid damage to the router and ports.2 Insert the DB-100 connector of the conversion cable into the DB-100 port on the4-Port Serial MIM3 Insert the DB-50 connector of a serial cable into one of the DB-50 connectors ofthe conversion cable.4 Connect the other end of the serial interface cable to one of the following devices:■ A CSU/DSU if the WAN is a leased line.■ The serial port of the analog modem if the WAN is a dialing line.5 Power on the router, and check the READY LED on the faceplate of the router. Ifthe LED is green, MIM has passed the POST and can operate normally. If the LED isoff, the POST failed and you should contact your Service representative.6 Check the status of the LINK LED on the 4-Port Serial MIM panel. If the LINK LED isgreen, the link is connected. If the LINK LED is off, the link is not connected andyou should check the line.2-Port E1/CE1/PRI MIM The 2-port E1/CE1/PRI MIM transmits and processes the E1 data streams. Inaddition, it provides access to CE1, implementing the ISDN PRI function so thatone board can serve multiple purposes.The 2-port E1/CE1/PRI MIM can be installed in any of the Router 5000 Family,except the Router 5012.Figure 40 2-Port E1/CE1/PRI MIMFeatures Table 32 lists features of the 2-port E1/CE1/PRI MIM.Table 32 Features of the 2-Port E1/CE1/PRI MIMFeature DescriptionConnector DB-15 (for 2-port E1/CE1/PRI MIM and 1-PortFractional E1 SIC)Number of connectors 2Interface standard G.703, G.704Interface speed 2.048MbpsCables E1 75-ohm non-balanced coaxial cableE1 120-ohm balanced twisted pair cable Coaxial connector, network interfaceconnector and 75-ohm to 120-ohm adapter(with BNC connector)
