FIELD OF INVENTION

The disclosed embodiments are generally directed to methods and systems for distributing signals, including video and data signals, to multiple consumers, with high bandwidth (BW) throughput data signals.

BACKGROUND

[Multimedia over Coax Alliance (MoCA) equipment provides for the distribution of high quality digital transmissions throughout facilities with coaxial cable, including facilities with legacy or existing coaxial cable. For example, MoCA equipment may provide high quality multimedia content transmissions over the existing coaxial cable in a residence. MoCA equipment may be used by cable, satellite and telecommunications service providers, and allows customers to receive broadband digital media content via satellite, cable, telephony or Internet network connections.
Under MoCA, consumers may use advanced data and video equipment and applications, such as integrated in-home multimedia distribution services including multi-room high definition (HD) digital video recorders (DVRs). Headend equipment, consumer premises equipment (CPE) and media centers may be used as MoCA compliant equipment. Media centers may store, manage and maintain the rights to content. Also, media centers may then communicate the content or distribute the content to other media appliances in the home. Headends may distribute data and video signals to one or more CPEs.

SUMMARY

Methods and systems for distributing signals, including video and data signals, to multiple consumers, with high bandwidth (BW) throughput data signals are disclosed herein. The methods and systems disclosed herein may include remote management, configuration, control and maintenance.
A headend may receive an input data signal over a fiber optic port and switch the signal to a plurality of data signals. The headend may convert the plurality of data signals, which may be Ethernet data signals or which may be converted to Ethernet data signals, to a plurality of output coaxial cable signals. Further, the headend may transmit the plurality of output coaxial cable signals via coaxial cable to a plurality of pieces of consumer premises equipment (CPE).
The output coaxial cable signals may be Multimedia over Coax Alliance (MoCA) compliant signals, and may comply with MoCA 1.1, MoCA 2.0 and/or MoCA 3.0. The input data signal may be up to a high bandwidth 10 gigabits per second (Gb/s) data signal received over a fiber optic port and each output coaxial cable signal may be up to a 1 Gb/s signal. The headend may also receive up to a 20 Gb/s signal through two transceivers connected to two fiber optic ports, up to a 30 Gb/s signal through three transceivers connected to three fiber optic ports, up to a 40 Gb/s signal through four transceivers connected to four fiber optic ports and up to a 50 Gb/s signal through five transceivers connected to five fiber optic ports.
The headend may receive the input data signal through a small form factor pluggable (XPF) fiber optic transceiver or a 12× small form factor pluggable (CXP) fiber optic transceiver. The headend may receive up to 10 GB/s, 20 Gb/s, 30 Gb/s, 40 Gb/s, 50 Gb/s, 100 Gb/s and 200 Gb/s data signals through one or more XPF fiber optic transceivers or CXP fiber optic transceivers.
In an example, the input data signal may be a Gigabit Passive Operating Network (GPON) signal. The GPON signal may be converted to an Ethernet signal.
The headend may transmit the 1 Gb/s data signal to each CPE in a set of multiple CPEs. As examples, the set of CPEs may include 4, 8, 16, 24, 48 or 64 CPEs.
The headend may transmit data and video signals over a radio frequency (RF) coaxial cable backbone to the CPEs. The headend may transmit the video signal and data signal at different frequencies over the same RF coaxial cable to each CPE. The headend may operate as a headend server and include local processing capabilities. In addition, the headend may receive one or more data signals from one or more CPEs over the coaxial cable backbone and transmit the one or more data signals over a fiber optic port.
In addition, a video on demand (VoD) server may route video and other data through the GbE switch to the headend. Also, the headend may operate as a headend server and include local processing capabilities. The headend may also receive one or more input CATV signals over one or more CATV line drops.
In an example, the headend may combine various features in a single device. For example, the headend may combine the features of converting Ethernet signals to coaxial cable signals, a VoD server, operating as a headend server and offloading transmissions from a wireless telecommunications provider.
In a further example, the headend may combine the features of receiving a GPON signal, converting the GPON signal to an Ethernet signal, operating as a headend server, then converting the Ethernet signal to a coaxial cable signal and transmitting the coaxial cable signal to a CPE. The headend may combine the features of receiving a GPON signal, converting the GPON signal to an Ethernet signal, operating as a headend server, then converting the Ethernet signal to a coaxial cable signal, transmitting the coaxial cable signal to a CPE and a VoD server. The headend may also combine the features of receiving a GPON signal, converting the GPON signal to an Ethernet signal, operating as a headend server, then converting the Ethernet signal to a coaxial cable signal, transmitting the coaxial cable signal to a CPE, a VoD server and offloading transmissions from a wireless telecommunications provider.

DETAILED DESCRIPTION

FIG. 1 is a system diagram of an example signal distribution system in which one or more disclosed embodiments may be implemented. As shown in system 100, an input data signal may be received from the Internet 120 and/or other networks, and may be routed through a router 132. The input data signal may be received through an Internet service provider (ISP), such as a cable television (CATV) service provider or a telecommunications provider. The input data signal may be received in a central wiring room 130 of a building. In an example, the input data signal may be an Ethernet signal.
In another example, the input data signal may be another type of signal. The building may be a large building, such as a hotel, office building or apartment building. The input data signal may be transmitted via a fiber optic cable. The router 132 may contain a firewall. The input data signal may then be routed through a gigabit Ethernet (GbE) switch 137 to a headend 140. In an example, transmission of the input data signal to the headend may be controlled by a remote management station 110. The input data signal may include high bandwidth (BW) signals, including up to 10 gigabits per second (Gb/s), 20 Gb/s, 30 Gb/s, 40 Gb/s, 50 Gb/s, 100 Gb/s and 200 Gb/s data signals.
The headend may receive the input data signal through a small form factor pluggable (XPF) fiber optic transceiver. As an example, the headend may receive up to a 10 Gb/s signal through a single XPF transceiver connected to a single fiber optic port. As further examples, the headend may receive up to a 20 Gb/s signal through two XPF transceivers connected to two fiber optic ports, up to a 30 Gb/s signal through three XPF transceivers connected to three fiber optic ports, up to a 40 Gb/s signal through four XPF transceivers connected to four fiber optic ports and a up to 50 Gb/s signal through five XPF transceivers connected to five fiber optic ports.
In a further example, the headend may receive up to a 40 Gb/s signal through a single XPF transceiver connected to a single fiber optic port. In another further example, the headend may receive up to an 80 Gb/s signal through two XPF transceivers connected to two fiber optic ports. In still another example, the headend may receive up to a 160 Gb/s signal through four XPF transceivers connected to four fiber optic ports. In yet another example, the headend may receive up to a 100 Gb/s signal through a single XPF transceiver connected to a single fiber optic port. In yet a further example, the headend may receive up to a 200 Gb/s signal through two XPF transceivers connected to two fiber optic ports.
In an additional example, the headend may receive up to 10 GB/s, 20 Gb/s, 30 Gb/s, 40 Gb/s, 50 Gb/s, 100 Gb/s and 200 Gb/s data signals through one or more 12× small form factor pluggable (CXP) fiber optic transceivers. One of ordinary skill in the art will appreciate that the CXP fiber optic transceiver may operate in a manner similar to that of the XPF transceiver as described herein.
Further, a video on demand (VoD) server 134 may route video and other data through the GbE switch 137 to the headend 140. The headend may receive the video and data through a first GbE input. In an additional example, the headend 140 may operate as a headend server and include local processing capabilities. The headend may also receive one or more input CATV signals over one or more CATV line drops 122. As an example shown in FIG. 1, the headend may receive 4 CATV signals. As further examples, the headend may receive 8, 16, 24 or 48 CATV signals or channels. The CATV line drops may include radio frequency (RF) coaxial cables. In an example, the headend may receive the input CATV signal from a cable TV service provider. In a further example, the headend my receive additional data from a second GbE switch through a second GbE input.
The headend may transmit the one or more video signals and one or more data signals to one or more pieces of consumer premises equipment (CPE) 160, 170, 180, 190. The headend may transmit the video signal and data signal at different frequencies over the same RF coaxial cable network 150 to each CPE. The cable network 150 may be a network in a large building. The headend may transmit a data signal of 1 Gb/s to each CPE in a set of multiple CPEs. As examples, the set of CPEs may include 4, 8, 16, 24, 48 or 64 CPEs. The data signal may be an Ethernet over coaxial cable (EoC) signal. Further, the data signal may be a Multimedia over Coax Alliance (MoCA) compliant signal. As an example, the headend and CPEs may operate in MoCA 1.1 EoC mode. As a further example, the headend and CPEs may operate in MoCA 2.0 EoC mode. Operation in MoCA 2.0 may include MoCA 2.0 turbo operation. In yet another example, the headend and CPEs may operate in MoCA 3.0 EoC mode.
In an example, the headend 140 may be located in a large building, such as an office building, apartment building or hotel, and may transmit the video and data signals to one or more CPEs, such as CPEs 160, 170, 180, 190, located in different offices, apartments or hotel rooms. Each CPE may be used by a different subscriber, consumer or customer. Each CPE may transmit data signals, through a wired or wireless connection, to up to four consumer or customer devices, such as a laptop or desktop computer, a voice over internet protocol (VOIP) telephone, a mobile telephone, a touch pad device and the like. The headend may transmit over an RF coaxial cable backbone to the CPEs. The RF coaxial cable backbone may include the coaxial cable infrastructure 150 of the large building. In addition, the headend may receive one or more data signals from one or more CPEs 160, 170, 180, 190 over the coaxial cable backbone and transmit the one or more data signals over a fiber optic port.
As used herein, a CPE may refer to a modem, a cable modem, an adapter, a subscriber box or a gateway, and these terms may be used interchangeably. A CPE may also have router functionality. As used herein, a headend may refer to multichannel data and video distribution equipment, and these terms may be used interchangeably.
FIG. 2 is a system diagram of an example headend and 8 CPEs. The headend may be used within the signal distribution system illustrated in FIG. 1. As shown in system 200, the headend 230 may include a switch 237 and one or more Ethernet to coaxial microchip processors, such as Ethernet to coaxial microchip processors 241, 242, 243, 244, 245, 246, 247, 248. The Ethernet to coaxial microchip processors may be MoCA microchip processors. In examples, the headend 230 may also include a gateway 232 or a video server 234 or both. In a further example, the headend 230 may operate as a headend server and include local processing capabilities.
The headend 230 may receive a high-speed internet access (HSIA) data signal 220. In an example, the headend 230 may receive the HSIA signal 220 through the gateway 232. The gateway 232 may include a dynamic host configuration protocol (DHCP) server and may send the data signal to the switch 237. The switch 237 may also receive video signals from a CATV provider or from a video server 234 or both. The switch 237 may transmit the video and data signals to one or more CPEs, such as CPE 251 (CPE 1) through CPE 258 (CPE 8). The switch 237 may transmit a data signal on a different channel frequency for each CPE and may transmit the video signal on a different frequency than that used for the data signals. The switch 237 may assign various throughput BWs to the CPEs, and may assign up to 1 Gb/s throughput BW. For example, the switch 237 may assign a 200 megabits per second (Mb/s) throughput BW, a 500 Mb/s throughput BW or a 1 Gb/s throughput BW to a CPE. In a further example, the switch may assign a throughput BW based on a setting for a service level set by a service provider, such as a cable TV service provider or a telecommunications provider. BW throughput assignment, provisioning and control may be remotely configurable. For example, an administrator 210 may send one or more commands 215 to a host 231, through a Universal Asynchronous Receiver/Transmitter (UART) to remotely configure BW throughput assignment, provisioning and control. The host 231 may transmit the command to the switch 237 through the Management Data Input/Output (MDIO) bus in the switch 237.
In a further example, the switch 237 may assign up to 2.6 Gb/s throughput to a CPE. In yet another example, the switch 237 may assign up to 3.4 Gb/s throughput to a CPE. In still another example, the switch 237 may assign up to 10 Gb/s throughput to a CPE. The switch 237 may provide a total data output throughput of varying amounts, depending upon the number of CPEs and the throughput set per CPE. As some examples, the switch 237 may provide a total data output throughput of up to 4, 8, 16, 24, 48, 64 and 200 Gb/s, based on the number of CPEs and the settings. In a further example, the switch 237 may provide a total data output throughput of up to 166.4 Gb/s, if, for example, a 2.6 Gb/s throughput were set for each of 64 CPEs. Depending upon additional capacity for data input, further total data output throughput may be provided. For example, the switch 237 may provide a total data output throughput of up to 217.6 Gb/s, if, for example, a 3.4 Gb/s throughput were set for each of 64 CPEs. In another example, the switch 237 may provide a total data output throughput of up to 640 Gb/s, if, for example, a 10 Gb/s throughput were set for each of 64 CPEs. The switch 237 may also provide additional options, with lower throughput for each CPE and a smaller number of CPEs.
As an example, the headend 230 may transmit the data and video signal to CPE 1 251 using BW1. Further, if the headend transmits to 8 CPEs at up to 1 Gb/s per CPE, the headend may transmit data signals on 8 channels, assign 8 BWs, and transmit a total of 8 Gb/s throughput. The headend may transmit the video signal on a different frequency than the data signals. As a further example, the headend may transmit to 4, 16, 24, 48 and 64 CPEs, and accordingly may transmit data signals on 4, 16, 24, 48 and 64 channels, assign 4, 16, 24, 48 and 64 BWs, and transmit a total of up to 4, 16, 24, 48 and 64 Gb/s throughput.
In a further example, if the headend transmits to 8 CPEs at up to 2.6 Gb/s per CPE, the headend may transmit data signals on 8 channels, assign 8 BWs, and transmit a total of 20.8 Gb/s throughput. The headend may transmit the video signal on a different frequency than the data signals. As a further example, the headend may transmit to 3, 4, 16, 24, 48 and 64 CPEs, and accordingly may transmit data signals on 3, 4, 16, 24, 48 and 64 channels, assign 3, 4, 16, 24, 48 and 64 BWs, and transmit a total of up to 7.8, 10.4, 41.6, 62.4, 124.8 and 166.4 Gb/s throughput. One of ordinary skill in the art will understand that the headend may transmit at other throughput amounts depending upon the number of CPEs the headend transmits to, the throughput per CPE and the available additional capacity of the input signals.
Further, the switch may send the signals to Ethernet to coaxial microchip processors for transmission to the CPEs via F connectors. The microchip processors may include MoCA compliant microchip processors. In an example, one microchip may be used for each CPE. In a further example, two microchip processors may be used for each CPE. Each Ethernet to coaxial microchip processor may receive an Ethernet signal from the switch, convert the Ethernet signal to a coaxial cable signal and transmit the signal via coaxial cable to a CPE.
As an example, the microchip processors may be MoCA 2.0 turbo microchip processors which may each transmit 500 Mb/s to each CPE. In this example, if the headend transmits to 8 CPEs, 8 MoCA 2.0 turbo microchip processors may be used. Further, the headend may transmit to 4, 16, 24, 48 and 64 CPEs and accordingly may use 4, 16, 24, 48 and 64 MoCA 2.0 turbo microchip processors. As a further example, the headend may use two MoCA 2.0 turbo microchip processors which may transmit 1 Gb/s to each CPE. The two microchip processors may be bonded. In this example, if the headend transmits to 8 CPEs, 16 MoCA 2.0 turbo microchip processors may be used. Further, the headend may transmit to 4, 16, 24, 48 and 64 CPEs and accordingly may use 8, 32, 48, 96 and 128 MoCA 2.0 turbo microchip processors.
In a further example, the microchip processors may be MoCA 3.0 microchip processors which may each transmit increased throughput, such as 2.6 Gb/s, 3.4 Gb/s or 10 Gb/s to each CPE. One of ordinary skill in the art will understand that various combinations of CPEs and throughput settings may be used under MoCA 3.0.
In a further example, the headend may include microchip processors that will provide the headend with the capability to transmit and receive up to 2.6 Gb/s to each CPE. Further, the processor may be capable of increased bandwidth transmission and reception, including, for example, 3.4 Gb/s, 10 Gb/s, 20 Gb/s, 30 Gb/s, 40 Gb/s, 50 Gb/s, 100 Gb/s and 200 Gb/s. In addition, the CPE may include a processor that will provide the CPE with the capability to transmit and receive up to 3.4 Gb/s. As in the headend, the processor of the CPE may be capable of increased bandwidth transmission and reception, including 10 Gb/s, 20 Gb/s, 30 Gb/s, 40 Gb/s, 50 Gb/s, 100 Gb/s and 200 Gb/s.
In a further example with 8 CPEs, the microchip processors may each transmit 2.6 Gb/s to each CPE. If the headend transmits to 8 CPEs for a total of 20.6 Gb/s throughput, 8 such 2.6 Gb/s microchip processors may be used.
Other various combinations of the microchip processors may be used to increase total throughput and throughput per CPE, as one of ordinary skill in the art will appreciate. Further examples of the combinations of the microchip processors are disclosed herein, although one of ordinary skill in the art will appreciate that examples beyond these may be used.
Each CPE may include a coaxial to Ethernet microchip and a switch. Further, each CPE may receive signals over an RF coaxial cable including a CATV video signal and a data signal. For example, CPE 251 (CPE 1), through coaxial to Ethernet microchip 261, may receive a signal over an RF coaxial cable from the headend 230, through Ethernet to coaxial microchip 241. The coaxial to Ethernet microchip 261 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 271. The switch 271 may then transmit the signals to up to four devices of the consumer or customer, such as a laptop or desktop computer through a wired or wireless connection, a voice over internet protocol (VOIP) telephone, a mobile telephone, a touch pad device and the like. In a further example, CPE 258 (CPE 8), through coaxial to Ethernet microchip 268, may receive a signal over an RF coaxial cable from the headend 230, through Ethernet to coaxial microchip 248. The coaxial to Ethernet microchip 268 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 278. The switch 278 may then transmit the signals to up to four devices of the consumer or customer. Similar transmissions may be made from the headend 230 to CPE 2 through CPE 7.
In addition, the headend 230 may receive a data signal from each CPE over the RF coaxial cable system and transmit the data signal to the Internet and/or other networks over the fiber optic port. The CPE may receive the data signal from a device of a consumer or customer. For example, CPE 251 (CPE 1), through switch 271, may receive a data signal from a device of a consumer or customer. The switch 271 may transmit the data signal to coaxial to Ethernet microchip 261. Then, the headend 230, through Ethernet to coaxial microchip 241, may receive the data signal from CPE 251 (CPE 1), through coaxial to Ethernet microchip 261. Further, CPE 258 (CPE 8), through switch 278, may receive a data signal from a device of another consumer or customer and the switch 271 may transmit the data signal to coaxial to Ethernet microchip 268. Then, the headend 230, through Ethernet to coaxial microchip 248, may receive the data signal from CPE 258 (CPE 8), through coaxial to Ethernet microchip 268. Similar transmissions may be made from CPE 2 through CPE 7 to the headend 230.
FIG. 3 is a system diagram of an example headend and 16 CPEs. In an example shown in system 300, the headend 330 may transmit to 16 CPEs, such as CPE 351 (CPE 1) through CPE 358 (CPE 16), and, accordingly, the headend 330 may transmit data signals on 16 channels and assign 16 BWs. The switch 337 may transmit a data signal on a different channel for each of the 16 CPEs. The headend 330 may transmit the video signal on a different frequency than the data signals.
Further, the switch 337 may send the signals to Ethernet to coaxial microchip processors, such as Ethernet to coaxial microchip 341 through Ethernet to coaxial microchip 348, for transmission to the 16 CPEs. Further, the headend 330 may receive a data signal from each CPE over the RF coaxial cable system and transmit the data signal to the Internet and/or other networks over the fiber optic port. In a further example, the headend 330 may operate as a headend server and include local processing capabilities.
Similarly to the example shown in system 200 in FIG. 2, in system 300 the headend 330 may receive an HSIA data signal 320 through a gateway 332, which may include a DHCP server and may then send the data signal to the switch 337. The switch 337 may also receive video signals from a CATV provider or from a video server 334 or both. Further, an administrator 310 may send one or more commands 315 to a host 331 to remotely configure BW throughput assignment, provisioning and control.
Further, as in system 200 in FIG. 2, each CPE may receive signals over an RF coaxial cable including a CATV video signal and a data signal. For example, CPE 351 (CPE 1), through coaxial to Ethernet microchip 361, may receive a coaxial cable signal from the headend 330, through Ethernet to coaxial microchip 341. The coaxial to Ethernet microchip 361 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 371 for transmission to up to four devices of the consumer or customer. In like manner, CPE 358 (CPE 16), through coaxial to Ethernet microchip 368, may receive a coaxial cable signal from the headend 330, through Ethernet to coaxial microchip 348, and coaxial to Ethernet microchip 368 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 378 for transmission to up to four devices of the consumer or customer. Similar transmissions may be made from the headend 330 to CPE 2 through CPE 15 (CPE 7 through CPE 15 not shown).
In addition, as in system 200 in FIG. 2, the headend 330 may receive a data signal from each CPE. For example, CPE 351 (CPE 1), through switch 371, may receive a data signal from a device of a consumer or customer and the switch 371 may transmit the data signal to coaxial to Ethernet microchip 361, which may transmit the signal to the headend 330, through Ethernet to coaxial microchip 341. Similarly, CPE 358 (CPE 16), through switch 378, may receive a data signal from a device of another consumer or customer and the switch 371 may transmit the data signal to coaxial to Ethernet microchip 368 for transmission to the headend 330, through Ethernet to coaxial microchip 348. Similar transmissions may be made from CPE 2 through CPE 15 (not shown) to the headend 330.
FIG. 4 is a system diagram of an example headend and 24 CPEs. In an example shown in system 400, the headend 430 may transmit to 24 CPEs, such as CPE 451 (CPE 1) through CPE 458 (CPE 24), and, accordingly, the headend 430 may transmit data signals on 24 channels and assign 24 BWs. The switch 437 may transmit a data signal on a different channel for each of the 24 CPEs. The headend 430 may transmit the video signal on a different frequency than the data signals.
Similarly to the example shown in system 200 in FIG. 2 and system 300 in FIG. 3, in system 400 the headend 430 may receive an HSIA data signal 420 through a gateway 432, which may include a DHCP server and may then send the data signal to the switch 437. The switch 437 may also receive video signals from a CATV provider or from a video server 434 or both. Further, an administrator 410 may send one or more commands 415 to a host 431 to remotely configure BW throughput assignment, provisioning and control.
Further, as in system 200 in FIG. 2 and system 300 in FIG. 3, each CPE may receive signals over an RF coaxial cable including a CATV video signal and a data signal. For example, CPE 451 (CPE 1), through coaxial to Ethernet microchip 461, may receive a coaxial cable signal from the headend 430, through Ethernet to coaxial microchip 441. The coaxial to Ethernet microchip 461 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 471 for transmission to up to four devices of the consumer or customer. In like manner, CPE 458 (CPE 24), through coaxial to Ethernet microchip 468, may receive a coaxial cable signal from the headend 430, through Ethernet to coaxial microchip 448, and coaxial to Ethernet microchip 468 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 478 for transmission to up to four devices of the consumer or customer. Similar transmissions may be made from the headend 430 to CPE 2 through CPE 23 (CPE 7 through CPE 23 not shown).
In addition, as in system 200 in FIG. 2 and system 300 in FIG. 3, the headend 430 may receive a data signal from each CPE. For example, CPE 451 (CPE 1), through switch 471, may receive a data signal from a device of a consumer or customer and the switch 471 may transmit the data signal to coaxial to Ethernet microchip 461, which may transmit the signal to the headend 430, through Ethernet to coaxial microchip 441. Similarly, CPE 458 (CPE 24), through switch 478, may receive a data signal from a device of another consumer or customer and the switch 471 may transmit the data signal to coaxial to Ethernet microchip 468 for transmission to the headend 430, through Ethernet to coaxial microchip 448. Similar transmissions may be made from CPE 2 through CPE 23 (not shown) to the headend 430.
FIG. 5 is a system diagram of an example headend and 48 CPEs. In an example shown in system 500, the headend 530 may transmit to 48 CPEs, such as CPE 551 (CPE 1) through CPE 558 (CPE 48), and, accordingly, the headend 530 may transmit data signals on 48 channels and assign 48 BWs. The switch 537 may transmit a data signal on a different channel for each of the 48 CPEs. The headend 530 may transmit the video signal on a different frequency than the data signals.
Similarly to the example shown in system 200 in FIG. 2, system 300 in FIG. 3 and system 400 in FIG. 4, in system 500 the headend 530 may receive an HSIA data signal 520 through a gateway 532, which may include a DHCP server and may then send the data signal to the switch 537. The switch 537 may also receive video signals from a CATV provider or from a video server 534 or both. Further, an administrator 510 may send one or more commands 515 to a host 531 to remotely configure BW throughput assignment, provisioning and control.
Further, as in system 200 in FIG. 2, system 300 in FIG. 3 and system 400 in FIG. 4, each CPE may receive signals over an RF coaxial cable including a CATV video signal and a data signal. For example, CPE 551 (CPE 1), through coaxial to Ethernet microchip 561, may receive a coaxial cable signal from the headend 530, through Ethernet to coaxial microchip 541. The coaxial to Ethernet microchip 561 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 571 for transmission to up to four devices of the consumer or customer. In like manner, CPE 558 (CPE 48), through coaxial to Ethernet microchip 568, may receive a coaxial cable signal from the headend 530, through Ethernet to coaxial microchip 548, and coaxial to Ethernet microchip 568 may then convert the coaxial cable signal to an Ethernet signal and send the signals to the switch 578 for transmission to up to four devices of the consumer or customer. Similar transmissions may be made from the headend 530 to CPE 2 through CPE 47 (CPE 7 through CPE 47 not shown).
In addition, as in system 200 in FIG. 2, system 300 in FIG. 3 and system 400 in FIG. 4, the headend 530 may receive a data signal from each CPE. One of ordinary skill in the art will understand that CPE 551 (CPE 1) through CPE 558 (CPE 48) in system 500 will transmit data to headed 530 similarly to that in system 200 in FIG. 2, system 300 in FIG. 3 and system 400 in FIG. 4.

The switch 637 may transmit a data signal on a different channel for each of the 16 CPEs. The headend 630 may transmit the video signal on a different frequency than the data signals.
Further, the switch 637 may send the signals to Ethernet to coaxial microchip processors, such as Ethernet to coaxial microchip 641 through Ethernet to coaxial microchip 648, for transmission to the 16 CPEs. Further, the headend 330 may receive a data signal from each CPE over the RF coaxial cable system and transmit the data signal to the Internet and/or other networks over the fiber optic port. In a further example, the headend 630 may operate as a headend server and include local processing capabilities.
In system 600, unlike in system 300 in FIG. 3, the headend 630 may receive an HSIA data signal 620 as a Gigabit Passive Operating Network (GPON) signal, through a single frequency unit 631. The GPON signal may be converted into an Ethernet signal by the single frequency unit 631 and then transmitted to a gateway 632, which may include a DHCP server. The gateway 631 may then send the data signal to the switch 637. The switch 637 may also receive video signals from a CATV provider or from a video server 634 or both. Further, an administrator 610 may send one or more commands 615 to a host 631 to remotely configure BW throughput assignment, provisioning and control.
Transmission from the headend 630 to CPE 651 (CPE 1) through CPE 658 (CPE 16) (CPE 7 through CPE 15 not shown) may operate in a manner similar to that in system 300, including the operation of coaxial to Ethernet microchip processors 661 through 668, Ethernet to coaxial microchip 641 to 648, switches 671 through 678. Also, transmission from CPE 651 (CPE 1) through CPE 658 (CPE 16) to headend 630 and then to gateway 632, may operate in a manner similar to the in system 300 in FIG. 3, except that gateway 632 may then transmit an Ethernet signal to single frequency unit 631, which may then convert the Ethernet signal to a GPON signal. The single frequency unit 631 may then transmit the GPON signal to the service or telecommunications provider.
