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...

5.The Lock stores this encrypted “expected value” and sends the dynamic 
challenge to the Key.
6. When the Key receives the challenge from the Lock, it uses the secret 
encryption key unqiue to the user ID assigned to the Key and encrypts the 
value the Lock sent. Following this, the Key calculates the necessary 
response. The Key transmits this “expected value” to the Lock.

To install a complete RPSD system, you need a Lock and a Key. A 
communications system and modem are assumed to be at the customer site 
already.
NOTE:
Although a printer is not essential to system operation, you should consider 
dedicating  a serial printer to the RPSD Lock. (The printer should be set to 
9600 kbps, N, 8, 1.) The System Activity Log can store up...

In the event of a unit failure or a power failure, the RPSD blocks incoming and 
outgoing calls to the port, protecting the port against unauthorized access. This 
call blocking also prevents the communications system or other protected 
resources from originating an alarm and blocks dial-up access to the port.
However, you can push in the POWER MONITOR button on the back of the Lock...
