Asynchronous Terminal Interface
Operation
Overview
You can configure and manage the CSU from an asynchronous 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 Asynchronous Terminal Interface (ATI) for CSU control.
By convention throughout this appendix, examples of screens are shown as they
appear with the standalone CSU.
Before Using the ATI
You can connect a terminal directly to the COM port of the CSU, or you can
establish a remote connection using dial-in (via the integral modem) or Telnet
access.
Before using the ATI, you may use the CSU’s front panel to set certain
configuration options for asynchronous terminal operation. Use the Configuration
(Cnfig) branch of the front panel menu and edit the User Interface (User)
configuration options for asynchronous terminal operation. Refer to
Changing
Configuration Options in Chapter 4, Configuration , and Appendix C, Configuration
Options .
To connect the asynchronous terminal to the CSU using Telnet access, refer to
Configuring the COM Port or Modem Port for SNMP or Telnet Access
in Chapter 4,
Configuration .
Restoring ATI Access
If the CSU is misconfigured, leaving it in a state that does not support
asynchronous terminal operation, the recovery procedure consists of power
cycling the CSU, waiting for the completion of the power-on self-test, and then
pressing the asynchronous terminal’s Return key five times in succession. (Begin
pressing the Return key within two seconds after the completion of power-on
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.
