2-Port T1/CT1/PRI MIM 43Figure 45 Extension Connection of an E1 120-Ohm Balanced Twisted Pair Cable5 Power on the router.6 Check the status of the corresponding READY LED on the panel. If the LED is on,the router has completed the POST and is operating normally. If the LED is off, thePOST failed and you should contact your Service representative.7 Check the status of the LINK LED (synchronous LED) on the panel of the 2-portE1/CE1/PRI MIM. If the light is off, signal synchronization failed and you shouldcheck the line.The E1 cable, coaxial connector, and network interface connector are all optionalaccessories so you must make these selections when you purchase 2-portE1/CE1/PRI MIMs.2-Port T1/CT1/PRI MIM The 2-Port T1/CT1/PRI MIM transmits and processes T1 data flow, provides CT1access, and fulfills the function of ISDN PRI.The 2-Port T1/CT1/PRI MIM can be installed in any Router 5000 Family except theRouter 5012.Each CT1 interface, also called a controller T1, is numbered as follows:■ The first CT1 interface is controller T1 0.■ Beginning from slot 0, the interfaces are numbered in ascending order. Thenext slot after CT1 0 is CT1 1, the next slot is CT1 2, and so on.■ Within an interface module, the CT1 interfaces are numbered to match thenumbering order on the module panel.For example, if you plug a 2-Port T1/CT1/PRI MIM into slot 1 in a Router 5682router, and a 2-Port T1/CT1/PRI MIM into slot 3, the two CT1/PRI interfaces in slot1 will be numbered CT1 0 and CT1 1 The two CT1/PRI interfaces in slot 3 will benumbered CT1 2 and CT1 3.When you use the timeslots binding command on a CT1 interface, the systemautomatically generates the corresponding serial interfaces.Figure 46 illustrates a 2-Port T1/CT1/PRI MIM:DB-15RJ-45RouterRJ-45120-ohm balanced twisted pairNetwork interface connector120-ohm E1 trunk cableNetworkdevices,such asleased line
