CSU/DSU MS DBU

VT100 Terminal Connection and Operation

To control the CSU/DSU MS DBU using a VT100 terminal:

1. Select a terminal interface through the front panel. Select 3 CONFIG,

5 MANAGEMENT, 1 INTERFACE, 1 TERM CONTROL.

2. Set the CONTROL RATE to match the VT100 terminal.

3. Using the provided VT100 terminal adapter cable, connect the COM port

of a VT100 compatible terminal or equivalent to the eight-pin modular jack

labeled CONTROL on the rear of the CSU/DSU MS DBU. This connection is

used for both local and remote configuration.

4. Establish the connection and press Enter repeatedly until the Terminal Menu

appears (Figure 3-3).

5. Make selections by entering the number corresponding to the chosen

parameter. Press ESC to return to the previous screen.

NOTE

Due to the increased display capabilities, the VT100 menu structure

differs from the front-panel interface. Appendix C includes the VT100

screens as well as a complete menu tree for accessing configuration

selections. Descriptions of individual menu options are provided

throughout this manual based on the front-panel menu structure. See

Figure 5-1 for the front-panel configuration menu tree.

When establishing a TELNET session, the system prompts for a

password. The default password is “blackbox.” This password can be

modified through the Management menu. See Chapter 10 for more

information.
