Introduction
The Remote Port Security Device (RPSD) is a single-line dial-up port protection
system that prevents unauthorized access to a host resource. Host resource
dial-up ports are protected by installing the RPSD Lock on the analog telephone
line leading to the port. Access is provided only when the calling party uses the
RPSD Key, a unit installed on the analog telephone line at the calling party end.
