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, the
POST failed and you should contact your Service representative.
7
Check the status of the LINK LED (synchronous LED) on the panel of the 2-port
E1/CE1/PRI MIM. If the light is off, signal synchronization failed and you should
check the line.
The E1 cable, coaxial connector, and network interface connector are all optional
accessories so you must make these selections when you purchase 2-port
E1/CE1/PRI MIMs.
2-Port T1/CT1/PRI MIM
The 2-Port T1/CT1/PRI MIM transmits and processes T1 data flow, provides CT1
access, and fulfills the function of ISDN PRI.
The 2-Port T1/CT1/PRI MIM can be installed in any Router 5000 Family except the
Router 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. The
next 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 the
numbering order on the module panel.
For example, if you plug a 2-Port T1/CT1/PRI MIM into slot 1 in a Router 5682
router, and a 2-Port T1/CT1/PRI MIM into slot 3, the two CT1/PRI interfaces in slot
1 will be numbered CT1 0 and CT1 1 The two CT1/PRI interfaces in slot 3 will be
numbered CT1 2 and CT1 3.
When you use the
timeslots binding
command on a CT1 interface, the system
automatically generates the corresponding serial interfaces.
