Step 1: Choose a synchronous/asynchronous serial interface cable depending on 
the type of the interface on the remote device.

Step 2: Plug the DB-28 connector of the cable to the appropriate DB28 port on 
the SAE module.

Step 3: Connect the other end of the SAE cable to:

■

Port of CSU/DSU if the WAN is a DDN line;

■

Serial port on an analog modem if the WAN is a dial-up line;

Step 4: Check the behavior of the LINK LED on the SAE panel. It is OFF when the 
line is faulty and signal is out of synchronization.

Like AS modules, 8/16-port enhanced asynchronous serial interface module 
(MIM-8ASE/MIM-16ASE) transmits/receives and handles asynchronous serial 
interface data streams. But ASE modules use RJ-45 connectors and AUX cables.

The interface attributes of MIM-8ASE/MIM-16ASE are given in the following table:

MIM-8ASE panel is shown in the following figure:
