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. 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
common configuration used in the DSU/CSU
market. Factory 2 options are read-only.
