Async Terminal Operation
You can use an async terminal in place of the front
panel to manage a standalone Model 3610 DSU. When
enabled, the async terminal interface:
•
Supports a VT100-compatible terminal
•
Is set to VT100 standards of 9.6 kbps data rate,
8 bits, 1 stop bit, and no parity
•
Emulates the front panel
Menus and selections are the same as operating the unit
from the front panel. However, the async terminal is not
limited to three selections per screen. An entire range of
selections or information is presented on one screen. If
connecting a modem for remote access, refer to
Appendix C, Async Terminal Operation.
Menu Structure
You access the menu tree, a representation of the
DSU’s menu structure, via the front panel. Use the menu,
shown in Appendix A, as a guide as you proceed through
the branches of the DSU.
The menus that appear depend upon the DSU’s
function within the network (i.e., control or tributary) and
the hardware options that are installed (e.g., a DBM or
MUX).
A Model 3610 DSU comes from the factory configured
as a tributary, while the Model 3611 DSU comes
configured as a control. Refer to Chapter 4 before
changing or customizing the default settings. Table A-1
lists all DSU factory default settings.
Top-Level Menu
Access to all network management tasks begins at the
top-level menu, the head of the menu hierarchy.
