Abstract

A system and method for modifying the spectrum allocation for DSL and LAN signals in accordance with bandwidth requirements of a small office, home office (SOHO) network is disclosed. After initiation of computers within the SOHO network, a handshake procedure is performed between the SOHO network and a wide area network (WAN). The handshake procedure discloses bandwidth requirements for the SOHO network to perform local communication between local area networks (LANs), and for the SOHO network to communicate with the WAN. As a result, the system modifies the spectrum allocation for digital subscriber line (DSL) and LAN signals associated with the SOHO network such that maximum bandwidth allocation is provided in accordance with actual bandwidth need.

Claims

1. A system for modifying bandwidth allocation in accordance with bandwidth requirements of a small office, home office (SOHO) network, having a series of computers therein, comprising:

a first transceiver, located within said SOHO; and

a second transceiver, located within a wide area network (WAN), wherein said first transceiver and said second transceiver are capable of specifying a required spectrum allocation for communication within said SOHO network, and between said SOHO network and said WAN, such that said system appropriately allocates bandwidth according to said specification,

wherein said second transceiver communicates with said first transceiver to determine whether to increase bandwidth use within said SOHO network by decreasing bandwidth use between said SOHO network and said WAN, and wherein said second transceiver communicates with said first transceiver to determine whether to increase bandwidth use between said SOHO network and said WAN by decreasing bandwidth use within said SOHO network.

2. The system of claim 1, wherein said computers within said SOHO network are divided into at least two local area networks (LANs).

3. The system of claim 1, wherein said specifying a required spectrum allocation is performed during a handshake procedure between said first transceiver and said second transceiver after initiation of said computers within said SOHO network.

4. The system of claim 3, wherein said handshake procedure is performed via use of a G.HS protocol.

5. The system of claim 3, wherein said handshake procedure is made via a digital subscriber line.

6. The system of claim 1, wherein said spectrum allocation is divided into a voice band, a data band, and a local band, wherein said voice band is the spectral allocation for plain old telephone service signals, said data band is the spectral allocation for asymmetric digital subscriber line signals, and said local band is the spectral allocation for local area network signals.

7. The system of claim 6, wherein said data band allocation has a lower boundary of approximately 30 kilohertz and an upper boundary of approximately 1 megahertz, and said local band allocation extends past 1 megahertz.

8. The system of claim 1, wherein said system can dynamically update said spectrum allocation in accordance with new communication requirements which effect bandwidth requirements for the transmission of data between said SOHO network and said WAN, and within said SOHO network.

9. The system of claim 1, wherein said system is an asymmetric digital subscriber line (ADSL) system.

10. A method of modifying bandwidth allocation in accordance with bandwidth requirements of a small office, home office (SOHO) network having a series of computers therein, comprising the steps of:

17. The method of claim 10, further comprising the step of dynamically updating said bandwidth spectrum allocation in accordance with new communication requirements which effect bandwidth requirements for the transmission of data between said SOHO network and said WAN, and within said SOHO network.
