The commands for TA configuration are modeled on the standard set used for analog modems with extensions for
the new ISDN functions. Commands for remote switch configuration and the unique ISDN functions required of
the terminal adapter have been added. The XEISDNS firmware contains an AT Command Help listing which can
be displayed by typing “AT&H” while in command mode. The module will respond with a listing of AT com-
mands with brief definitions of each. The complete command set listing appears in the Configuration Guide along
with examples of configuration profiles for typical applications.
Menu Configuration
The second configuration method uses a group of Setup Menus built into the XEISDNS firmware. These menus
are accessed by entering the AT command “@SETUP” while the module is in Command Mode. Keyboard com-
mands from a PC in VT100 terminal emulation mode allow the user to move through the complete set of configu-
ration choices, enter variable data, and store the results. Operation of the Setup Menus are explained in the Con-
figuration Guide.
Stored Configurations
A complete set of configuration parameters must be in place each time the XEISDNS places a call. However the
current parameters are held in volatile memory and are lost when the host equipment power is interrupted. Also,
once a working configuration has been established for a particular ISDN line, terminal equipment set, and service
type there is no need to change it for each call. To speed up and/or automate the call setup process stored configu-
rations are provided in the XEISDNS.
Two types of stored configurations are provided: factory defaults and user defined configurations. Factory defaults
are stored in Flash memory while user defined sets are stored in EEPROM. The factory default configuration sets
provided represent setups for common applications. Descriptions of these are contained in the Configuration
Guide. There are provisions for two user defined configuration sets. In addition the settings associated with
switch parameters are stored and accessed separately to help prevent accidental changes. Extended AT commands
are provided to store and load these configuration sets upon power up or separately. These commands are detailed
in the Configuration Guide.
