This menu is your map through the DSU’s various

functions and pathways. Compare it against the menus
that appear as you move through procedures. You will
learn to quickly access where you want to go on the menu
when operating the DSU. (This menu is also included on
the Reference Card that comes with this guide, which can
be removed and placed with your DSU.)

The DSU’s operation is represented as menu selections

that branch downward from its starting point, the top-level
menu, like the roots of a tree. The menu is sometimes
referred to as a menu tree.

The top-level menu is the starting point for all DSU

operations. You can always return to this point from
anywhere in the menu by pressing the  

  key. Pressing

The following shows an example of the top-level menu

for a standalone Model 3550 DSU that is configured as a
control operating at 9.6 kbps, with an NMS message
waiting.

F1

Port1  DSU  9.6 C
Local    Remot   Msg

F2

F3

The following information is displayed:

Line 1 – Source of the information being displayed

– DSU’s current function or mode (In this 

example, the unit is operating as a DSU, 
not as a DBM or TDM/Flex.)

– DSU’s data rate

– DSU’s network designation (Here the 

DSU is a control.)

If this display was for a Model 3551 (a 
carrier-mounted DSU), the carrier (nest or

 

rack) and slot numbers would appear 
instead of Port 1 (e.g., Carrier 2 and

 

Slot 16 would appear as 2:16).

Line 2 – Menu selections, one appearing directly 

over each function key (F1 and F2).
