Home network system and method
View Patent ↗A demarcation point unit connected between a home network backbone and an external network. The demarcation point unit includes a blocking filter and splitter. The blocking filter receives a home network signal from the home network backbone and an external signal from the external network. The blocking filter separates the home network signal from the external signal, and returns the home network signal back to the home network backbone. The splitter has an input and at least two outputs. The input of the splitter receives the home network signal from the blocking filter.
1. A network module for use in a home network, said network having RF transmission characteristics, the network module that is connected via a local bus to a plurality of other network modules, the network module comprising:
a diplexer that receives an analog signal and separates a home network signal from the received analog signal;
a modem that converts the home network signal into a digital signal; and
a media access controller (“MAC”) that interfaces with a protocol of the local bus and participates in arbitration with the plurality of other network modules to deliver the digital signal to the local bus;
wherein the network module transmits a self-train burst, the self-train burst that calibrates the network module to the RF transmission characteristics of the home network.
2. The network module of claim 1 wherein, in response to a predetermined burst transmitted by a master module in the network, the plurality of other network modules in the network and the network module are synchronized.
3. The network module of claim 1 wherein, in response to a request for a guaranteed quality of service, the network module further receiving an allocation of bandwidth.
4. The network module of claim 1 further adapted to receive a grant signal from a master module that indicates that the network module can transmit a burst.
5. The network module of claim 1 wherein the network module transmits an empty burst that communicates that the network module includes no data to transmit.
6. The network module of claim 1 wherein a master module in the home network is configured to change the order of transmission opportunities among the plurality of other network modules and the network module in the home network.
7. A method for calibrating a network module for use in a home network, said network having RF transmission characteristics, the network module that is connected via a local bus to a plurality of other network modules, the method comprising:
using the network module to receive an analog signal;
using the network module to separate a home network signal from the received analog signal;
converting the home network signal into a digital signal;
delivering the digital signal to the local bus wherein a media access controller (“MAC”) interfaces with a protocol of the local bus;
participating in arbitration with the plurality of other network modules to deliver the digital signal to the local bus; and
calibrating the network module to the RF transmission characteristics of the home network by using the network module to transmit a self-train burst.
8. The method of claim 7 wherein, in response to receiving a predetermined burst transmitted by a master module in the network, synchronizing the plurality of other network modules in the network and the network module.
9. The method of claim 7 further using the network module to receive an allocation of bandwidth in response to providing a request for a guaranteed quality of service.
10. The method of claim 7 further comprising using the network module to receive a grant signal from a master module, the grant signal that indicates that the network module can transmit a burst.
11. The method of claim 7 further comprising using the network module to transmit an empty burst that communicates that the network module includes no data to transmit.
12. The method of claim 7 further comprising using a master module to change an order of transmission opportunities among the plurality of other network modules in the home network and the network module.
