Changing Configuration Options
The DSU/CSU 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
DSU/CSU; invalid combinations of configuration options do not appear. For
example, menus displayed for the Model 3160 (2 ports) and the Model 3164
(4 ports) differ due to the number of ports available. Also, if the DTE Drop/Insert
(DSX-1) 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
DSU/CSU varies with your configuration.
The DSU/CSU offers configuration options located in the following memory areas:
Active (Activ) – This is the configuration option set currently active for the
DSU/CSU. Before a configuration option set becomes active for the DSU/CSU,
you must save the set to the Active area. When the DSU/CSU 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.
Customer 1 (Cust1) – This is the first of two sets of customer-defined
configuration options. This area can be written to.
Customer 2 (Cust2) – This is the second of two sets of customer-defined
configuration options. This area can be written to.
Factory 1 (Fact1) – This is a set of configuration options preset at the factory.
This set is determined by what is considered to be the most common
configuration used in the DSU/CSU market. Factory 1 options are read-only.
Factory 2 (Fact2) – This is a set of configuration options preset at the factory.
This set is determined by what is considered to be the second most commo n
configuration used in the DSU/CSU market. Factory 2 options are read-only.
