Asynchronous Terminal Operation
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.
