Asynchronous Terminal Operation

H

Overview

You can configure and manage the DSU/CSU from an asynchronous (async) terminal that is configured for 9.6 kbps, 8 characters, no parity, and 1 stop bit.

This appendix provides operational examples to help you become familiar with the use of the async terminal for DSU/CSU control.

By convention throughout this appendix, examples of screens are shown as they appear with the standalone 4-port DSU/CSU.

Before Using the Asynchronous Terminal

You can connect the async terminal directly to the COM port of the DSU/CSU, or you can establish a remote connection using dial-in (via the integral modem) or Telnet access.

Before using the async terminal, you may use the DSU/CSU’s front panel to set certain configuration options for async terminal operation. Use the Configuration (Cnfig) branch of the front panel menu and edit the User Interface (User) configuration options for async terminal operation. Refer to Changing Configuration Options in Chapter 3, Operation, and Appendix C, Configuration Options.

To connect the async terminal to the DSU/CSU using Telnet access, refer to

Configuring the DSU/CSU for SNMP or Telnet Access in Chapter 3, Operation.

If the DSU/CSU is misconfigured, leaving it in a state that does not support async terminal operation, the recovery procedure consists of power cycling the DSU/CSU, waiting for the completion of the power-up self-test, and then pressing the async terminal’s Return key five times in succession. (Begin pressing the Return key within two seconds after the completion of power-up self-test, and do not wait longer than one second between each successive key press.) This procedure allows you to use the System Paused screen to reset the COM port configuration options or to reload all factory default configuration options.
