Changing Configuration
Options
The E1 NTU is an intelligent device that displays only
valid options for the current configuration. Therefore, you
are only presented with menu choices that are consistent
with the current configuration and operational state of the
E1 NTU; invalid combinations of configuration options
do not appear. For example, menus displayed for the
Model 3360 (2 ports) and the Model 3364 (4 ports) differ
due to the number of ports available. Also, if the G.703
DTE interface selection is disabled, many of the menu
choices do not appear. Be aware that although all options
are shown in this guide, what you see on your E1 NTU
varies with your configuration.
The E1 NTU offers four sets of configuration options
located in the following memory areas:
•
Active (Activ). The configuration option set active
for the E1 NTU is stored here. Before a
configuration option set becomes active for the E1
NTU, you must save the set to the Active area.
When the E1 NTU is shipped from the factory, the
Active configuration option set is identical to the
Factory set. This area can be written to and controls
the current operation of the device.
