MIM-8ASE/MIM-16ASE Module 79

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.

MIM-8ASE/MIM-16AS

E Module

Introduction 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.
