Abstract

A preemptive telecommunication interface is provided with a microprocessor, non-volatile storage media containing a database, and software. The microprocessor is capable of reading incoming signals designating telephone numbers from the telephone company. The microprocessor is further capable of comparing an incoming telephone number to an authorized list of telephone numbers kept in the database. If an incoming telephone number is among those authorized, the telephone call is "answered" and a telecommunication line is connected to a main computer system or facsimile machine. If the incoming telephone number is not among those authorized, the telephone call is "preempted" (i.e., not answered).

Claims

1. A method for accessing a computer from a remote location, said method comprising the steps of:

a. receiving a signal on a telephone line, said signal designating an incoming telephone number of a telephone caller;

b. storing said incoming telephone number in a buffer;

c. comparing said incoming telephone number to a list of authorized telephone numbers in order to determine if said incoming telephone number is among said list of authorized telephone numbers, said list of authorized telephone numbers being kept in a memory device; and

d. if said incoming telephone number is among said list of authorized telephone numbers, then;

d1. automatically connecting a supply of electrical power to a totally deactivated computer resulting the booting up said computer; and

d2. automatically connecting said telephone line to said booted up computer.

2. A method as in claim 1 further comprising the steps of:

e. determining the date and time from a clock; and

f. storing said date, time and said incoming telephone number in a storage means.

3. An apparatus for accessing a computer from a remote location, said apparatus comprising

receiving means for receiving a signal on a telephone line, said signal designating an incoming telephone number of a telephone caller;

buffer means for storing said incoming telephone number received by said receiving means;

storage means for storing a list of authorized telephone numbers;

comparison means for comparing said incoming telephone number to said list of authorized telephone numbers in said storage means, said comparison means providing a positive signal if said incoming telephone number is among said authorized telephone numbers and a negative signal if said incoming telephone number is not among said authorized telephone numbers; and

connection means, responsive to said positive signal, for automatically connecting a supply of electrical power to a totally deactivated computer resulting in the booting up of said computer, and automatically connecting said telephone line to said booted up computer.

4. An apparatus as in claim 3 wherein said buffer means is a dynamic random access memory.

5. An apparatus as in claim 3 wherein said storage means is a disk memory.

6. An apparatus as in claim 3 wherein said comparison means comprises:

a microprocessor, said microprocessor in operative connection with said buffer means and said storage means, said microprocessor capable of reading said incoming telephone number from said buffer means, said microprocessor further capable of sequentially reading said authorized telephone numbers on said storage means and comparing each of said authorized telephone numbers to said incoming telephone number to determine if said incoming telephone number exactly matches one of said authorized telephone numbers, said microprocessor means further capable of writing said positive signal to said connection means in the event that said incoming telephone number matches one of said authorized telephone numbers, said microprocessor further capable of writing said negative signal to said connection means in the event that said incoming telephone number does not match any of said authorized telephone numbers.

7. An apparatus as in claim 3 wherein said connection means comprises an electrically controlled switch.

8. An apparatus for activating a totally deactivated computer or facsimile machine from a remote location, said apparatus comprising

receiving means for receiving a signal on a telephone line, said signal designating an incoming telephone number of a telephone caller;

buffer means for storing said incoming telephone number received by said receiving means;

storage means for storing a list of authorized telephone numbers;

comparison means for comparing said incoming telephone number to said list of authorized telephone numbers in said storage means, said comparison means providing a positive signal if said incoming telephone number is among said authorized telephone numbers and a negative signal if said incoming telephone number is not among said authorized telephone numbers; and

connection means, responsive to said positive signal, for automatically connecting a supply of electrical power to the totally deactivated computer or facsimile machine resulting in the activation of said computer or facsimile machine, and automatically connecting said telephone line to said activated computer or facsimile machine.
