CSU/DSU MS/DBU
3.5 Configuration
The CSU/DSU MS/DBU contains four different user profiles (sets of
configuration options), listed in
Appendix B
, that are stored in read only
memory. The unit is shipped from the factory with profile 1 (default
configuration) loaded into the non-volatile configuration memory. If profile
1 matches the desired system requirements, then no additional configuration
is required to put the unit into service. If profile 1 does not match the
desired system requirements, there are two options available:
1. Modify the default configuration.
2. Select one of the other profiles that more nearly matches the desired
configuration, then modify to required specifications.
When a new profile is loaded, or the existing profile is modified, it is
stored in the non-volatile configuration memory. The CSU/DSU MS/DBU
is then configured with that profile every time power is turned on, or the
unit is reset.
The CSU/DSU MS/DBU provides four different methods for local
configuration and three different methods for remote configuration.
1. Front panel
2. AT commands
3. V.25 bis
4. Remote commands

The front panel provides access to all operation parameters of the CSU/DSU
MS/DBU through a multi-level menu structure that begins with the four-part
main menu.
1=STATUS—Displays status of network and DTE interface
2=TEST—Controls local and remote testing
3=CONFIG—Displays/changes current configuration parameters
4=DIAL—Provides manual dialing functions (available only when unit
is configured for SW56 operation)
3.5.2 “AT” C
OMMANDS
In addition to the front panel, the CSU/DSU MS/DBU can be configured
and controlled with in-band AT commands from an asynchronous DTE
port just as modems are.
