Caution:
Before connecting an SAE module, confirm the model of the equipment to be
connected (that is, the synchronous/asynchronous mode, DTE/DCE mode, and so on),
signaling criterion required by the access equipment, baud rate, and timing clock.
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:
z
Port of CSU/DSU if the WAN is a DDN line;
z
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.
3.5 MIM-8ASE/MIM-16ASE Module
3.5.1 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.
