Abstract

An entry device includes an entry port, a filter connected to the entry port, a plurality of first output ports, and a plurality of second output ports. A first path extends from the entry port, through the filter, to the first output ports. The first path is configured to pass cable television (CATV) signals therethrough and to prevent at least a portion of multimedia over coax alliance (MoCA) signals from passing therethrough. A second path extends from the entry port, through the filter, to the second output ports. The second path is configured to prevent at least a portion of the CATV signals and at least a portion of the MoCA signals from passing therethrough. A third path extends from the first output ports, through the filter, to the second output ports. The third path is configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough.

First claim

What is claimed is:

1. An entry device, comprising:
an entry port configured to receive cable television (CATV) signals from a headend;
a low-band filter connected to the entry port and configured to pass the CATV signals therethrough and to prevent at least a portion of multimedia over coax alliance (MoCA) signals from passing therethrough;
a high-band filter connected to the low-band filter and configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough;
a broadband splitter connected to the low-band filter and the high-band filter;
a high-band splitter connected to the high-band filter;
a plurality of first output ports connected to the broadband splitter;
a plurality of second output ports connected to the high-band splitter;
wherein a first path extends from the entry port, through the low-band filter and the broadband splitter, to the first output ports;
wherein the first path is configured to pass the CATV signals therethrough and to prevent at least a portion of MoCA signals from passing therethrough;
wherein a second path extends from the entry port, through the low-band filter, the high-band filter, and the high-band splitter, to the second output ports;
wherein the second path is configured to prevent at least a portion of the CATV signals and at least a portion of the MoCA signals from passing therethrough;
wherein a third path extends from the first output ports, through the broadband splitter, the high-band filter, and the high-band splitter, to the second output ports;
wherein the third path is configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough; and
wherein the first output ports, the second output ports, or both are configured to be connected to one or more devices in a subscriber premises.

2. The entry device of claim 1 , wherein the entry port is configured to be connected between the headend and the subscriber premises.

3. The entry device of claim 1 , wherein the high-band splitter is configured to operate at frequencies between 1100 MHz and 2000 MHz.

4. The entry device of claim 3 , wherein the high-band splitter is not configured to operate at frequencies below 1100 MHz and above 2000 MHz.

5. The entry device of claim 1 , further comprising a directional coupler connected to the first output ports, wherein the directional coupler is configured to attenuate the CATV signals by more than 6 dB.

6. An entry device, comprising:
an entry port configured to receive cable television (CATV) signals from a headend;
a filter connected to the entry port;
a plurality of first output ports;
a plurality of second output ports;
a first path from the entry port, through the filter, to the first output ports;
a second path from the entry port, through the filter, to the second output ports;
a third path from the first output ports, through the filter, to the second output ports;
wherein the first path is configured to pass CATV signals therethrough and to prevent at least a portion of multimedia over coax alliance (MoCA) signals from passing therethrough;
wherein the second path is configured to prevent at least a portion of the CATV signals and at least a portion of the MoCA signals from passing therethrough;
wherein the third path is configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough; and
wherein the first output ports, the second output ports, or both are configured to be connected to one or more devices in a subscriber premises.

7. The entry device of claim 6 , wherein the entry port is configured to be connected to the headend.

8. The entry device of claim 6 , further comprising a high-band splitter connected to the filter and the second output ports, wherein the high-band splitter is configured to operate at frequencies between 1100 MHz and 2000 MHz.

9. The entry device of claim 8 , wherein the high-band splitter is not configured to operate at frequencies below 1100 MHz and above 2000 MHz.

10. The entry device of claim 6 , wherein the filter comprises:
a low-band filter configured to pass the CATV signals therethrough and to prevent at least a portion of the MoCA signals from passing therethrough; and
a high-band filter configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough.

11. The entry device of claim 6 , further comprising a broadband splitter in the first path and the third path but not in the second path, wherein the broadband splitter is configured to operate at frequencies at or below 1675 MHz.

12. The entry device of claim 6 , wherein the broadband splitter is not configured to operate at frequencies above 1675 MHz.

13. An entry device, comprising:
an entry port configured to receive cable television (CATV) signals from a headend;
a filter connected to the entry port;
a plurality of first output ports;
a plurality of second output ports;
a first path from the entry port, through the filter, to the first output ports;
a second path from the entry port, through the filter, to the second output ports;
a third path from the first output ports to the second output ports;
wherein the first path is configured to pass CATV signals therethrough and to prevent at least a portion of multimedia over coax alliance (MoCA) signals from passing therethrough
wherein the second path is configured to prevent at least a portion of the CATV signals and at least a portion of the MoCA signals from passing therethrough;
wherein the third path is configured to pass the MoCA signals therethrough and to prevent at least a portion of the CATV signals from passing therethrough; and
wherein the first output ports, the second output ports, or both are configured to be connected to one or more devices in a subscriber premises.

14. The entry device of claim 13 , wherein the entry port is configured to be connected to the headend.

15. The entry device of claim 13 , wherein the entry device is configured to be installed between the headend and the subscriber premises.

16. The entry device of claim 13 , further comprising a high-band splitter connected to the filter and the second output ports, wherein the high-band splitter is configured to only pass the MoCA signals therethrough.

17. The entry device of claim 16 , wherein the high-band splitter is configured to prevent the CATV signals from passing therethrough.
