Step 3: Check the behavior of the LINK LED on the MIM-8ASE/MIM-16ASE panel.

It is OFF when fault has occurred on the link and signal is out of synchronization.

In this case, please check the link.

Introduction MIM-1E1/MIM-2E1/MIM-4E1

MIM-1E1/MIM-2E1/MIM-4E1, the 1-/2-/4-port channelized E1/PRI interface module, transmits, receives, and processes E1 data traffic. In addition, you can use the card for other purposes, such as CE1 access and the ISDN PRI function.

MIM-1E1-F/MIM-2E1-F/MIM-4E1-F

The MIM-1E1-F/MIM-2E1-F/MIM-4E1-F module is different from the

MIM-1E1/MIM-2E1/MIM-4E1 module in the sense that:

■The FE1 operating mode supported by the E1-F cards allows only one n ⋅ 64 kbps bundle to be formed on each interface, where n = 1 to 31. However, an E1 card allows arbitrary grouping of 31 channels and multiple bundles.

■The E1-F modules do not support PRI mode.
