Additional information on operating the DSU’
s keypad
can be found in the procedures used to install and verify
operation of the DSU in Chapters 2 and 3, the procedure
for editing configuration options in Chapter 5, and the
various procedures scattered throughout this chapter.
Menu Structure
The menu is your map through the DSU’
s various
functions. The following sections describe each branch
and subbranch, and provide procedures for operating
certain features. Appendix A
shows the complete menu
and describes the DSU’
s branches and subbranches. (
The
menu is also included on the Refer
ence Car
d that comes
with this guide
.)
Top-Level Menu
The top-level menu is the
starting point
for all DSU
operations. Y
ou can always return to this point from
anywhere in the menu by pressing the
key
. Pressing
this key immediately terminates any operation or work in
progress. Refer to
Appendix A as you read about the
branches and subbranches.
The standalone Model 3615 DualFlow DSU indicates
whether the DDS or DBM line interface is being
monitored. The carrier-mounted Model 3616 DualFlow
DSU displays the DSU’
s carrier and slot location in the
cabinet.
When there are simultaneous DSU (V.35) and Dial
(232) connections (e.g., as in a Dial Diagnostic – DiDg
configuration), the top-level screen toggles between two
displays every 10 seconds, displaying the status of each of
the two ports, the EIA-232-D port for the router
management or user data and the V.35 port for the user
data.

Status Branch
The Status (Stat) branch reports on the health and
status of the DSU, DBM, the DTE interfaces, the quality
of the dial connection, the identity of the DSU (model
number, serial number, etc.), and the terminal’
s power
(where it checks the presence of voltage on the DTE’s
RTS lead).
