Dumb terminal cable

Connect the RJ-45 connector (female) to a standard network cable and then to a 
dumb terminal adapter;

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.

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.

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.
