configuration that has already been done. Any active calls, however, will be
terminated.
A normal reset can also be performed using the reset button located on the back
of the ISDN LAN Modem.

A factory reset restores the ISDN LAN Modem configuration to the factory
default settings listed in Appendix C. All previously configured settings are
cleared and current calls are terminated.
To reset the ISDN LAN Modem, do the following.
