Integrated security and communications system with secure communications link
First Claim
1. A secure communications system comprising:
- a first communication station connected to a communication medium;
a central communication station connected to said communication medium; and
at least a second communication station connected to said communication medium;
wherein;
all communication between said first communication station and said central communication station is initiated by said first communication station;
communication between said first communication station and said second communication station is established by leaving a message for said first communication station at said central communication station indicating communication is desired between said first communication station and said second communication station; and
when said first communication station periodically initiates communication with said central communication station, said first communication station receives said message for said first communication station, maintains its initiated communication with said central communication station and instructs said central communication station to relay communications between said first communication station and said second communication station.

Abstract
An integrated security and communications system combines a security system to either or both of a telephone system interface and a data interface. Data functions such as electronic mail and possible partial or full World Wide Web access may also be provided at keypads of the security system, as well as at connected personal computers or computer terminals. The system keypads may be enhanced to better accommodate some of the added functions. A central communications station could be used to maintain secure, shared private key encrypted communications with each premises system, using a redirector arrangement or relay to allow each premises system to communicate securely with a central monitoring station and with other systems. The secure communications system could be used without a security system to allow secure computer-to-computer communications.
