E1 DSU/CSU User Interface
Access Security
NOTE
This page of the manual is self-
supporting and can be removed to
prevent unwanted knowledge of the
security access levels and their
selection.
The user interface access security option allows you to
limit access to the E1 DSU/CSU to display-only and
non-intrusive functions.
Level 1 (Lvl1) access security allows access to all
functions available through the menu tree. This is the
default setting.
Level 2 (Lvl2) access security restricts access to only
those functions that cannot affect the operation of the E1
DSU/CSU in any way. At this level,
•
None of the functions in the Test or Ctrl branches
are available.
•
All functions on the Stat branch are available.
•
All functions on the Cnfg branch are available for
display, but they cannot be used to save to a
configuration area (Activ, Cust1, Cust2, or Fact).
You can only reach the screen that controls security
access using the front panel.
