Abstract

A twisted pair and/or coaxial cable fed, integrated residence gateway controlled set-top device provides a plurality of services. One service is lifeline service which may be provided over the coaxial cable via a cable modem of the integrated residence gateway or over the twisted pair facility. An integrated residence gateway is coupled to either or both of the coaxial cable or twisted pair and distributes the bandwidth facilities available over either service vehicle to customer devices including a set top box. For corporate telecommuters who work from home, a greater variety of services is available. The greater bandwidth of the cable network allows for the faster exchange of information between home and office, allowing the employee working at home to function as if he or she were actually at the office. Individual pieces of equipment connected to the telecommuter'"'"'s home may be addressed, so that phone and message forwarding may be properly forwarded to the telecommuter'"'"'s home. Dynamic allocation of the bandwidth available on the cable network allows cable head ends to provide multiple tiers, or levels, of service such that the higher service tiers are less likely to lose bandwidth when traffic increases. Advanced billing options automatically bill the employer for costs associated with telephone calls placed from the telecommuter'"'"'s home.

Claims

1. A method for allowing an employee to access an employer'"'"'s office network to work from home, comprising the steps of:

responsive to receiving outgoing data signals from one or more pieces of equipment associated with the employee'"'"'s home, an integrated residence gateway converting said outgoing data signals into outgoing packets and transmitting said outgoing packets to a head end via a cable network;

responsive to receiving said outgoing packets, said head end transmitting said outgoing packets to said office network;

responsive to receiving incoming packets from said office network, said head end transmitting said incoming packets to said integrated residence gateway;

responsive to receiving said incoming packets, said integrated residence gateway converting said incoming packets into incoming data signals, and distributing said incoming data signals to one or more of said pieces of equipment,

wherein the transmission of said incoming and outgoing packets forms a data connection between the employee'"'"'s integrated residence gateway and the office network, further comprising the steps of;

receiving a request from the employee to reverse the charges for the data connection;

consulting a database to determine whether the employer has agreed to pay for the data connection; and

billing said employer, and not the employee, for the cost of the data connection.

2. The method of claim 1, further comprising the steps of said integrated residence gateway transmitting data to and receiving data from said head end via a local exchange carrier.

3. The method of claim 1, wherein said steps of conversion further include encryption and decryption of the data to be transmitted.

4. The method of claim 1, wherein said incoming and outgoing data signals include signals for a telephone call.

5. The method of claim 4, further comprising the steps of:

responsive to receiving incoming telephone signals for said employee, said office network converting said incoming telephone signals to said incoming packets and transmitting said incoming packets to said head end.

6. The method of claim 5, wherein said incoming packets are addressed to a specific telephone that is connected to said integrated residence gateway.

7. The method of claim 1, wherein said incoming packets are addressed to said integrated residence gateway.

8. The method of claim 7, wherein said incoming packets are further addressed to a particular piece of equipment connected to said integrated residence gateway.

9. The method of claim 7, wherein said incoming packets are further addressed to a particular category of equipment that could be connected to said integrated residence gateway.

10. The method of claim 7, further comprising the step of automatically keeping the head end up-to-date regarding the active pieces of equipment connected to said integrated residence gateway by transmitting messages to said head-end.

11. The method of claim 1, further comprising the step of dynamically allocating the bandwidth on said cable network among customers connected to said cable network based on level of service purchased by said customers.

12. The method of claim 11, wherein said step of dynamically allocating the bandwidth on said cable network does not affect the bandwidth allocated to customers who have purchased dedicated bandwidth.

13. A method for allowing an employee to access an employer'"'"'s office network to work from home, comprising the steps of:

responsive to receiving outgoing data signals from one or more pieces of equipment associated with the employee'"'"'s home, an integrated residence gateway converting said outgoing data signals into outgoing packets and transmitting said outgoing packets to a head end via a cable network;

responsive to receiving said outgoing packets, said head end transmitting said outgoing packets to said office network;

responsive to receiving incoming packets from said office network, said head end transmitting said incoming packets to said integrated residence gateway;

responsive to receiving said incoming packets, said integrated residence gateway converting said incoming packets into incoming data signals, and distributing said incoming data signals to one or more of said pieces of equipment,

wherein the transmission of said incoming and outgoing packets forms a data connection between the employee'"'"'s integrated residence gateway and the office network;

determining that the data connection is for purposes of allowing the employee to work from home;

billing the employer, and not the employee, for the cost of the data connection;

receiving a signal from said employee indicating that said employee wishes to connect to said office network from a second location that is not the employee'"'"'s home;

responsive to receiving said signal, establishing a second data connection between said office network and said second location; and

billing the cost of said second data connection to said employer.
