Note: The "!" commands are used to change certain fundamental configuration
parameters which are changed very infrequently - often, only once at
installation. Using these "!" commands during normal operation with the
telephone line connected to the Terminal Adapter (TA) can cause
unpredictable results. It is best to issue the "!" commands when the TA is not
connected to the ISDN network to avoid confusion between the TA and ISDN
network. The recommended procedure for using the "!" commands is as
follows:(1) Disconnect the ISDN phone line from the TA. (2) Issue the "!"
commands to set the correct value for the "!" command related parameters.(3)
Issue the AT&Wn" command to store the parameters changed during step (2)
in the user profile ".(4) Reconnect the ISDN phone line.(5) Reset or reboot the
ISDN sub-system with the updated configuration parameters.
