Selecting a Factory Configuration
The leased line/dial-up modems have five factory default and five user
configurations. Any of these configurations can be called into action by the
AT command set, by association with a dialed number, or by the front
panel. The default factory configuration is for the most common application
of dial-up operation (AT&F0).
The factory configurations are:
Leased Line Factory Configurations 0 through 4
•

As shipped from the factory, "Factory Configuration 0" is also stored as the
"User Configuration 0", "Factory Configuration 1" is also stored as "User
Configuration 1", "Factory Configuration 2" is also stored as "User
Configuration 2", "Factory Configuration 3" is also stored as the "User
Configuration 3", and "Factory Configuration 4" is also stored as "User
Configuration 4". The desired differences can then be entered and stored
as user defined configurations. The factory configurations are defined in
Table 3.1 by using the DIAL-UP, AT&F0, as the reference and the basic
configuration.
