Abstract

A community access or cable television (CATV) entry adapter interfaces to a CATV network and serves as a hub in a Multimedia over Coax Alliance (MoCA) network. MoCA signals communicated between active ports of the entry adapter are rejected by MoCA frequency rejection filters to avoid interfering with the functionality of an eMTA subscriber device connected to a passive port of the entry adapter, without interfering with the passage of CATV upstream and downstream active and passive signals.

TECHNICAL FIELD OF THE INVENTION The present invention relates to community access or cable television (CATV) networks and to a coaxial cable multimedia alliance (M〇CA) in-home entertainment network. The present invention relates to a new and improved CATV entry adapter that conducts CATV downstream and upstream signals between a subscriber device connected to an access adapter and a CATV network and is connected to an access adapter. The M〇CA signal is transmitted between the m〇CA-enabled (MoCA-enabled) devices while preventing the MoCA signal from interfering with the embedded multimedia terminal adapter (eMTA) such as the "lifeline" phone that is also connected to the access adapter. The correct function of the device. [Prior Art] The CATV network uses interconnected coaxial cables, signal splitters, and H« instruments, ferries, trunks, Line taps, spurs and ^ 201145907 The infrastructure of his signalling device to provide both downstream signals... and its from the "head end, @ main signal distribution agency _ CATV, the resident's station (family) And office). Downstream signals operate subscriber devices such as televisions, telephones, and computers. In addition, most catv networks also transmit “upstream” signals from the subscriber device back to the head end of the CATV network. For example, a subscriber uses a set-top box to select a program to display on a television set. As another example, when using a CATV infrastructure to connect to the public Internet: People: Brain's two-way communication is essential @. As another example, an Internet Protocol Voice (V〇IP) telephone uses a CATV infrastructure and a public domain network as a communication medium for communicating two-way telephone conversations. <In order to allow simultaneous delivery of upstream and downstream CATVs (4) and interoperability of devices associated with the Chaotic CATV network infrastructure outside the subscriber premises and subscriber premises, downstream and upstream signals are limited to two different frequency bands. In most CATV networks, the downstream band is in the range of 54-1002 deadhertz (MHZ), while the upstream band is in the range of m MHz. The downstream signal is delivered from the catv network infrastructure sneak to the subscriber premises at the CATV access adapter (which is also commonly referred to as an access device, terminal adapter, or branch (dr〇p) amplifier). The access adapter is a multi-drop device that connects to the CATV branch profile from the CATV network infrastructure at the access port and 4+ connects to the coaxial cable at many other distribution ports, the coaxial cable extending through Pass the subscriber station to the cable exit. Each cable outlet is available: connected to the subscriber device. Typically, most homes have coaxial cables that extend to the cable exits in almost the room, as different types of subscriber devices may be made in different rooms. For example, televisions, computers, and telephones are typically used in many different rooms in the home or 201145907 office. A plurality of distribution ports of the access adapter deliver downstream signals to each cable outlet and conduct upstream signals from the subscriber device through the access adapter to the branch cable and CATV infrastructure. In addition to televisions, computers and telephones, a relatively large number of other entertainment and multimedia devices can be used in the home. For example, a digital video recorder (DVR) is used to record broadcast programs, still photos, and moving pictures in a memory medium so that the content can be played back on a display or television at a later time selected by the user. As another example, a computer game is also played on a display or television. Such computer games may be those obtained on the Internet by CATV.com or those obtained from media played on a replay device connected to a display or television. As yet another example, a receiver of a satellite broadcast signal can be placed in the home for viewing or listening. These types of devices 'including more traditional televisions, telephones, and devices connected to the Internet via CATV_' are generally referred to as multimedia devices.

在家中或者訂戶駐地中的多個不同位置使用多媒體裝置的期望導致了同軸纜線多媒體聯盟（MoCA)的創建。 M〇CA已開發了產品規範以創建用於互連目前已知和未來，多媒體裝置的在家娛樂網路。在家網路使用最初 =在訂戶駐地内分送CATV信號㈣立的訂戶駐地或者在豕同軸纜線基礎設施’主要是因為該同軸纜線基礎設施已存在於大部分家庭中並且能夠承栽比CATV頻帶中承載的資訊多得多的資訊。通過將一賦能的或M0CA介面裝置連接在訂戶駐地的房間中的境線出口處，來建立财A 201145907 網路。這些M〇CA介面裝置實現M〇CA通信協定，其將通常由多媒體裝置使用的信號封裝在M〇CA信號分組中並且隨後在連接在其他缆線出口處的其他M〇CA介面裝置之間傳遞m〇ca信號分組。接收M〇CA介面裝置從m〇ca信^ 分組移除封裝的多媒體信號’並且將多媒體信號遞送到所連接的顯示器 '電腦或者其他多媒體裝置，内容從所述顯不器、電腦或者其他多媒體裝置呈現給用戶。每個MoCA賦能的裝置能夠與在家或訂戶駐地的 Moca _中的每個其他M〇CA_的裝置通信以在家中或訂戶駐地中各處遞送多媒體内容。可獲得自一個多媒體裝置的多媒體内容可以在家中的不同的位置顯示、播放或者以其他形式被使用，而不必在物理上將發端多媒體裝置個位置重新定位到訂戶駐地中的另—位置。多媒體内容的傳遞在更全面地利用現代家庭中存在的多媒體裝置的方面破視為是有益的。由於訂戶駐地的M0CA網路的操作必須與CATV服務的操作同時進行，因此，M〇CA信號利用不同於CATV上游和下游信號的頻率範圍的頻率範圍。典型的MoCA頻帶是1125_1525 MHz。這種M〇CA信號的斤。月的D頻帶被劃分為八個不同的頻率範圍D卜別，並且這八個不同的D頻率範圍用於確保選定的M〇CA賦能的裝置之間的通信。例如，處於1125·1175 MHz的D]頻帶可以用於在與房子的主房間中的機上盒關聯的M〇ca介面裝置和連接到房子的臥室中的電視機的另一 m〇ca介面裝置之間傳_ CATV電視節目内容，而連接到房子的地下室中 201145907 的電腦遊戲多媒體裝置的MoCA介面裝置同時在處於 1375-1425 MHz的D_6頻帶上將電腦遊戲内容傳遞到與位於房子的娛樂室中的電腦關聯的另一 M〇CA介面裝置。 m〇ca頻帶還包括其他頻率範圍，但是由於D頻帶主要用於建立MoCA介面裝置之間的連接，因此D頻帶是主要相關的（of major relevance)。儘管使用訂戶駐地的同軸纜線基礎設施作為通信介質顯著地簡化了 MoCA網路的實現，但是這樣做存在某些缺點。MoCA信號具有穿過CATV接入裝置並且進入cATV 網路基礎設施的能力，其中這些M〇CA信號隨後可以穿過刀支窥線並且進入另一訂戶的駐地。她鄰訂戶駐地處的 MoCA彳5號的存在彳貝害了最初預期僅限制在原始訂戶駐地中的資訊的私密性和安全性。通過CATV網路進入另一訂戶駐地的來自原始訂戶駐地的MoCA信號也具有不利地影響其他訂戶駐地中的MoCA網路的性能的可能性。來自原始和其他訂戶駐地的MoCA信號的衝突可能引起MoCA介面裝置發生故障或者不正確地操作。 CATV網路遭受來自所謂的侵入雜訊的不利影響，該雜訊從位於訂戶駐地處的外部源進入CATV網路。侵入雜訊的典型範圍是在0-15 MHz的頻帶中，但是也可以存在於其他上游或下游頻率。侵入雜訊減輕裝置已被開發用於扼制或減少0-42 MHz頻帶中的來自訂戶駐地的侵入雜訊，但是 MoCA頻率範圍中的1125-1525 MHz信號明顯處於正常侵入雜訊的範圍之外。因此，典型的侵入雜訊扼制裝置對於 201145907 禁止MoCA信號是無效的。駐留在5-42 MHz和54-1002 MHz的CATV信號頻帶外的MoCA信號可能構成CATV網路的另一噪音源，單獨的 MoCA頻率抑制（frequency rejection)濾波器已被開發用於外部連接到CATV接入適配器，以努力保持M〇CA頻率信號被限制於訂戶駐地。然而，這種裝置的使用遭受未授權的移除、篡改、原始安裝時的疏忽，以及可能導致過早失靈或故障的物理曝露。由於CATV網路和在家纜線基礎設施最初預期用於分送CATV信號，因此也出現了問題。典型的在家纜線基礎設施使用信號***器將單個CATV下游信號劃分為多個 CATV下游信號並且將多個CATV上游信號組合為單個 CATV上游仏號。CATV接入適配器最初並非預期用於在其有源埠之間傳遞MoCA信號，而這對於在m〇CA網路中實現MoCA信號傳遞是必要的。為了實現m〇cA網路，m〇CA 信號必須在連接到多個有源埠的信號***器/組合器的分離的信號分量腳（leg)之間穿越或“跳躍”。該信號穿越被稱為“***器跳躍”。典型的信號***器在其分離的信號分量腳之間具有高度的信號抑制或隔離。當MoCA信號在***器的分離的信號分量腳之間跳躍或穿越時，信號抑制或隔離的程度極大地使MoCA信號的強度衰減。由於在家纜線基礎設施的不可預測的差異’物理MoCA信號通信路徑也是可變的。 MoCA通信協定截別可變強度m〇ca信號的可能性並且提 201145907 供提升MoCA信號強度以補償否則將在M〇CA弒能的裝置之間傳遞的MoCA信號的可變強度的能力。The desire to use multimedia devices at home or in multiple locations in subscriber premises has led to the creation of the Coax Multimedia Alliance (MoCA). M〇CA has developed product specifications to create home entertainment networks for interconnecting currently known and future multimedia devices. Home network usage initially = distribution of CATV signals within the subscriber premises (four) of the subscriber station or in the coaxial cable infrastructure 'mainly because the coaxial cable infrastructure already exists in most homes and can be built to CATV The information carried in the frequency band is much more information. The A 201145907 network is established by connecting an enabled or M0CA interface device to the exit of the environment in the subscriber's premises. These M〇CA interface devices implement M〇CA communication protocols that encapsulate signals typically used by multimedia devices in M〇CA signal packets and then pass between other M〇CA interface devices connected at other cable exits. M〇ca signal grouping. Receiving the M〇CA interface device to remove the encapsulated multimedia signal from the m〇ca message packet and delivering the multimedia signal to the connected display 'computer or other multimedia device from the display, computer or other multimedia device Presented to the user. Each MoCA-enabled device can communicate with each other device in the home or subscriber's Moca__ to deliver multimedia content throughout the home or subscriber premises. Multimedia content available from a multimedia device can be displayed, played, or otherwise used at different locations in the home without physically relocating the originating multimedia device location to another location in the subscriber's premises. The delivery of multimedia content is seen as beneficial in more fully utilizing the multimedia devices that exist in modern homes. Since the operation of the subscriber station's M0CA network must be performed concurrently with the operation of the CATV service, the M〇CA signal utilizes a frequency range that is different from the frequency range of the CATV upstream and downstream signals. A typical MoCA band is 1125_1525 MHz. This kind of M〇CA signal is pounded. The D band of the month is divided into eight different frequency ranges D, and these eight different D frequency ranges are used to ensure communication between the selected M〇CA enabled devices. For example, the D] band at 1125·1175 MHz can be used for the M〇ca interface device associated with the set-top box in the main room of the house and another m〇ca interface device for the television set connected to the bedroom of the house. The content of the CATV TV program is transmitted, and the MoCA interface device of the computer game multimedia device connected to the basement of the house in 201145907 simultaneously transfers the computer game content to the entertainment room located in the house in the D_6 band of 1375-1425 MHz. Another M〇CA interface device associated with the computer. The m〇ca band also includes other frequency ranges, but since the D band is primarily used to establish connections between MoCA interface devices, the D band is of major relevance. Although the use of the subscriber premises' coaxial cable infrastructure as a communication medium significantly simplifies the implementation of the MoCA network, there are certain disadvantages to doing so. The MoCA signal has the ability to traverse the CATV access device and enter the cATV network infrastructure, where these M〇CA signals can then pass through the knives and enter the premises of another subscriber. The presence of MoCA彳5 at her neighbouring subscriber's premises was a breach of privacy and security that was originally intended to limit information only to the original subscriber's premises. The MoCA signal from the original subscriber premises entering the other subscriber premises through the CATV network also has the potential to adversely affect the performance of the MoCA network in other subscriber premises. Conflicts of MoCA signals from the original and other subscriber premises may cause the MoCA interface device to malfunction or operate incorrectly. The CATV network suffers from the adverse effects of so-called intrusion noise that enters the CATV network from an external source located at the subscriber's premises. The typical range of intrusive noise is in the 0-15 MHz band, but can also exist in other upstream or downstream frequencies. Intrusion noise mitigation devices have been developed to tweak or reduce intrusive noise from subscriber premises in the 0-42 MHz band, but the 1125-1525 MHz signal in the MoCA frequency range is clearly outside the range of normal intrusion noise. Therefore, the typical intrusion noise suppression device is ineffective for the 201145907 prohibition of the MoCA signal. MoCA signals outside the band of CATV signals at 5-42 MHz and 54-1002 MHz may constitute another source of noise for the CATV network, and a separate MoCA frequency rejection filter has been developed for external connection to CATV. Access the adapter in an effort to keep the M〇CA frequency signal limited to the subscriber premises. However, the use of such devices suffers from unauthorized removal, tampering, negligence in the original installation, and physical exposure that may result in premature failure or malfunction. A problem has also arisen since the CATV network and home cable infrastructure were originally expected to be used to distribute CATV signals. A typical home cable infrastructure uses a signal splitter to divide a single CATV downstream signal into multiple CATV downstream signals and combine multiple CATV upstream signals into a single CATV upstream apostrophe. CATV access adapters were not originally intended to pass MoCA signals between their active ports, which is necessary to implement MoCA signaling in m〇CA networks. In order to implement the m〇cA network, the m〇CA signal must traverse or “jump” between the separated signal component legs connected to the signal splitters/combiners of multiple active turns. This signal crossing is called a "split jump." A typical signal splitter has a high degree of signal rejection or isolation between its separated signal component legs. When the MoCA signal hops or traverses between the split signal components of the splitter, the degree of signal suppression or isolation greatly attenuates the strength of the MoCA signal. Due to the unpredictable differences in home cable infrastructure, the physical MoCA signal communication path is also variable. The MoCA communication protocol intercepts the possibility of a variable-intensity m〇ca signal and provides the ability to boost the MoCA signal strength to compensate for the variable strength of the MoCA signal that would otherwise be passed between the M〇CA capable devices.

MoCA信號的強度或功率可以遠遠大於在訂戶駐地中傳遞的CATV信號的強度或功率。較高功率的信號The strength or power of the MoCA signal can be much greater than the strength or power of the CATV signal delivered in the subscriber premises. Higher power signal

可以由如下情況產生..Moca裝置通過提升所傳送的M〇CA 信號的強度或功率對減小的信號強度進行 *如下簡單事實產生:一V下游信號在上者：基礎設施上穿越的明顯更長的信號路徑，M0CA信號在訂. 戶駐地的Moca網路中穿越明顯更短的信號路徑。因此，It can be generated by the fact that the Moca device performs a reduced signal strength by increasing the intensity or power of the transmitted M〇CA signal. * The following simple facts are generated: a V downstream signal is above: the infrastructure is significantly more traversing With a long signal path, the M0CA signal traverses a significantly shorter signal path in the Moca network of the subscriber premises. therefore,

MoCA信號具有不利地影冑CATV訂戶設備的正確功能的能力。來自Moca信號的顯著不利影響的一個示例出現在如下類型的CATV接入適配器中：其具有無源信號分送璋和多個有源信號分送埠。這種CATV接人適配器將無源CATV 下游信號提供給無源埠並且從連接到無源埠的eMTA裝置接收無源CATV上游信號。CATV接入適配器還將有源 CATV下游信號提供給其多個有源埠中的每—個並且從其多個有源埠中的每一個接收有源CATV上游信號。這種接，適配器包括***器，其將CATV下游信號劃分為無源信说和有源信號。無源信號在它們從無源埠被遞送到訂戶設 1之前被傳導通過接入適配器而不經放大、調節或修改。有源信號通常傳導通過前向路徑放大器，其中放大器在將 CATV下游信號從有料遞送到有源訂戶設備之前，對這些 CATV下游信號的強度進行放大，或者對這些Μη信號的 201145907 一些特性進行修改或調節。大部分訂戶設備受益於放大的 CATV下游信號。CATV接人適配器上的大部分埠是有源埠。通常對於每個接入適配器僅提供-個無源埠。連接到接入適配器的無源埠的訂戶設備是嵌人式多媒體終端適配器（eMTA)裝置，典型地是“通信聯絡” m eMTA 裝置組合了規線數據機和類比電話適配器 '纖線數據機提供用於向和從CATV網路傳遞網際協^分組的資料介面，並且類比電話適配器提供了用於類比電話機的網際協定語音（驗）介面。eMTA裝置在類比語音信號和分組之間: 行轉換。通信聯絡電話是eMTA裝置的公知示例。傳導通過接入適配器的無源信號在它們被從無源蜂遞送到無源eMTA訂戶設備之前不經歷接入適配器中的放大、調節或修改。it常，無源信號預期在緊急條件下保持可獲得和有用。通信聯絡電話機的功能不能取決於無源信號路徑中的放大器或其他有源信號調節器的正確功能。因此，較之在連接到接入適配器的有源埠的M〇CA裝置之間傳遞的MoCA信號的功率，eMTA通信聯絡電話裝置接收的無源CATV下游信號具有相對低的功率。接入適配器包括：上游帶通濾波器，其傳導5 42 頻帶中的CATV上游信號；以及下游帶通濾波器，其傳導 54-1002 MHz頻帶中的CATV下游信號。儘管CATV上游和下游帶通濾波器預期用於基本上抑制（rej ect )它們的帶通頻率之外的信號’但是1 125-1525 MHz頻帶中的明顯較局功率的MoCA信號有能力以足以匹敵或超過 10 201145907 (predominate )從無源埠遞送到eMTA訂戶設備的CATV 下游無源仏號的強度的強度透過典型的CATV上游和下游帶通濾波器。MoCA信號對於eMTA訂戶設備是雜訊，並且eMTA訂戶設備不會回應於M〇CA信號而運轉。然而，The MoCA signal has the ability to adversely affect the correct functioning of the CATV subscriber device. One example of a significant adverse effect from the Moca signal occurs in a CATV access adapter of the type that has a passive signal distribution 璋 and a plurality of active signal distribution 埠. This CATV access adapter provides passive CATV downstream signals to the passive ports and receives passive CATV upstream signals from eMTA devices connected to the passive ports. The CATV access adapter also provides active CATV downstream signals to each of its plurality of active ports and receives active CATV upstream signals from each of its plurality of active ports. Such a connector includes a splitter that divides the CATV downstream signal into passive signal and active signals. Passive signals are conducted through the access adapter without being amplified, adjusted or modified before they are delivered from the passive port to the subscriber set 1. The active signal is typically conducted through a forward path amplifier where the amplifier amplifies the strength of these CATV downstream signals prior to delivering the CATV downstream signals from the bulk material to the active subscriber device, or modifies some of the characteristics of these Μn signals 201145907 or Adjustment. Most subscriber devices benefit from amplified CATV downstream signals. Most of the ports on the CATV access adapter are active. Usually only one passive port is provided for each access adapter. The passive subscriber equipment connected to the access adapter is an embedded multimedia terminal adapter (eMTA) device, typically a "communication contact". The m eMTA device combines a line data modem with an analog telephone adapter' fiberline data provider. A data interface for communicating Internet Protocol packets to and from the CATV network, and an analog telephone adapter provides an Internet Protocol voice interface for analog phones. The eMTA device is between analog voice signals and packets: line conversion. A communication telephone is a well-known example of an eMTA device. Passive signals conducted through the access adapter do not experience amplification, adjustment or modification in the access adapter until they are delivered from the passive bee to the passive eMTA subscriber device. It is often the case that passive signals are expected to remain available and useful under emergency conditions. The function of the communication telephone cannot depend on the correct function of the amplifier or other active signal conditioner in the passive signal path. Thus, the passive CATV downstream signal received by the eMTA communication telephone device has relatively low power compared to the power of the MoCA signal transmitted between the active 〇M〇CA devices connected to the access adapter. The access adapter includes an upstream bandpass filter that conducts the CATV upstream signal in the 542 band and a downstream bandpass filter that conducts the CATV downstream signal in the 54-1002 MHz band. Although CATV upstream and downstream bandpass filters are expected to be used to substantially reject (rej ect) signals outside their bandpass frequencies, the significantly higher power MoCA signals in the 1 125-1525 MHz band are capable of matching Or more than 10 201145907 (predominate) The intensity of the CATV downstream passive nickname delivered from the passive 埠 to the eMTA subscriber device passes through the typical CATV upstream and downstream bandpass filters. The MoCA signal is a noisy message to the eMTA subscriber device and the eMTA subscriber device does not operate in response to the M〇CA signal. however,

For this reason, CATV access adapters that are also used as part of the M〇CA network suffer from the isolation or suppression of the M()Ca signal at the source, compared to the active and access ports of the access adapter. At present, no material isolation of about 6G dB is considered to be desirable. Only for subscriber devices that are not MoCA-enabled, the problem arises that the power from the m〇ca signal interferes with the correct functioning of the passive eMTA subscriber device connected to the CATV access adapter. The M〇CA-enabled subscriber device is expected to respond to the MoCA signal operation' and as a result, has the ability to suppress unwanted m〇ca signals when also responding to CATV downstream and upstream signal operations. Currently, most passive subscriber devices are not enabled by M〇CA. Therefore, the problem of the MqCA signal blocking the correct functioning of passive subscriber equipment in a catv access adapter that also conducts M〇CA signals in the MoCA network of the subscriber premises is obvious. SUMMARY OF THE INVENTION The present invention is directed to a CATV access adapter that advantageously contributes to MoCA's home network without degrading the quality of the signals and services provided to the eight-fold subscriber device and from the eMTA subscriber device 11 201145907 set up. The CATV access adapter of the present invention effectively eliminates the interference effects of the MoCA signal at its passive bee' thereby avoiding the problem of the MgCa signal interfering with the correct function of the passive eMTA subscriber device. The present invention allows for efficient use of eMTA subscriber devices that are not MoCA enabled when the access adaptation II is used as a hub for transferring MoCA signals between the devices of the active ports connected to the access adapters. Therefore, when a subscriber network is established at the subscriber premises, the non-MoCA-enabled subscriber equipment can be effectively used without incurring additional costs to the subscriber. The CATv Access Adapter also enhances the strength of the MqCa signal transmitted in the MqCA network. To achieve these and other improvements, one aspect of the present invention relates to a CATV access adapter having access ports for the same network to pass cm downstream and upstream signals and also for transmitting to subscriber devices at the subscriber premises. Passive distribution of the downstream and upstream signals of the CATV and multiple active distributions. Unwanted to connect to an eMTA subscriber device. The active device is adapted to connect to the CAV subscriber device and the M〇CA (four) capable subscriber device in the m〇ca network at the subscriber premises. The plurality of active ports also deliver MoCA signals between the subscriber premises of the MoCA network in the subscriber premises that are connected to the active network. The first bidirectional splitter/combiner of the access adapter has a public terminal that connects to the same CATV network to deliver CATV downstream and upstream signals. The first splitter/combiner also has first and second separated signal component legs. The first splitter/combiner causes the CATV downstream signal to split into split CCTV downstream signals and provides each split CATV downstream signal 12 201145907 to the first and second signal component legs. The first splitter/combiner creates a single combined upstream signal based on each upstream signal received at the first and second signal component legs and provides the combined upstream signal to the public terminal. The passive signal communication path extends between the first signal component leg and the passive port of the first splitter/combiner. The passive signal communication path conducts a passive signal between the passive chirp and the first signal component leg of the first splitter/combiner. The active signal communication path extends from the second signal component leg of the first splitter/combiner to conduct an active signal to and from the second signal component leg of the first splitter/combiner. The second bidirectional splitter/combiner has a common terminal and a plurality of separate signal component legs. Each signal component pin is connected to an active port. The second splitter/combiner splits each signal received at its common terminal into split signals and provides each split signal to each signal component foot. The second splitter/combiner also creates a combined active signal from each CATV upstream signal and M〇CA signal received at each signal component leg and provides the combined active signal to its common terminal. The second splitter/combiner performs signal splitting and signal combining on the CATV downstream signal, the CATV upstream signal, and the m〇ca signal. A first M〇CA frequency rejection filter is coupled between the active signal communication path and the second splitter/combiner. The first-MoCA frequency suppression chopper suppresses a substantial portion of the power rate from the MoCA nickname present at the common terminal of the second splitter/combiner and passes to and from the transmission with substantially no attenuation Upstream and downstream signals from active bee CATV. An additional aspect of the CATV access adapter relates to a first MOCA frequency suppression filter that reflects power from a MoCA signal received from a common terminal of the second splitter/combiner back to the second splitter/combiner a common terminal, and the second splitter/combiner supplies the MoCA signal reflected from the first M〇CA frequency suppression filter as a split reflection M〇CA signal to the signal component leg of the second splitter/combiner, thereby increasing The efficiency and power of the MoCA signal distribution between the active ports of the access adapter. The reflected MoCA signal adds power to the ΜC A signal that traverses or jumps between the signal component legs of the signal splitter/combiner. Another additional aspect of the CATV access adapter involves a second m〇ca frequency rejection filter coupled in the passive signal communication path between the first signal component leg and the passive port of the first splitter/combiner. The second m〇ca frequency rejection filter suppresses a substantial portion of the power of the MoCA signal present at the first signal component leg from the first splitter/combiner, thereby eliminating or reducing] the VioCA signal pair being connected to the passive port The eMTA subscriber device affects and maintains the quality of CATV upstream and downstream signals delivered to and from the connection to the & source #eMTA subscriber device. Yet another additional aspect of the CATV access adapter involves a third frequency suppression filter coupled between the common terminal of the first splitter/combiner and the access port. The second M〇CA frequency rejection filter suppresses a substantial portion of the power of the MoCA signal present at the common terminal from the first splitter and 13 and passes through to and from the access without substantial attenuation上游 CATV upstream and downstream signals. The third M〇CA signal frequency suppression chopper blocks the Moca signal from the M〇CA network of the subscriber premises to the CATV network and blocks the false M〇CA from the CATv network to the MoCA network at the subscriber premises. Signal conduction. 14 201145907 Another aspect of the invention relates to a method for preventing MoCA signal interference between MoCA-enabled subscriber devices connected to a CATV access adapter in a MoCA network from an eMTA subscriber connected through a CATV access adapter Communication of the device to the CATV network. The method includes: connecting an eMTA subscriber device to a passive port of the access adapter, passing the passive CATV downstream and upstream signals between the CATV network and the eMTA subscriber device through the access adapter and the passive port, each M The CA-enabled subscriber device is connected to one of the plurality of active ports of the access adapter, and the MoCA signal is transmitted between the MoCA-enabled subscriber devices in the M〇CA network through the access adapter and the active port. Splitting the CATV downstream signal received from the CATV network into split CATV downstream signals in the access adapter and providing a split CATV downstream signal to the passive port and providing other split downstream signals to the active port, in the access adapter The CATV upstream signal received from the passive port and the active bee is combined into a CATV combined upstream signal and the CATV combined upstream signal is provided from the access adapter to the catv network, which will be received from the active port in the access adapter. The CATv upstream signal lifetime m〇CA signal is combined into a combined right-handed sister s σ active 彳5唬 by supplying the combined active signal | to the _ Μ Γ Δ phase in the access adapter. Xuan & Suppressing the filter to suppress a substantial portion of the power of the W MoCA signal in the self-assembled active signal, and passing the downstream and upstream signals of the combined active signal through the first - ΜΓ Δ with substantially no attenuation Doosan MoCA frequency suppression filter. An additional aspect of the s-hai method involves the use of a first MoCA frequency to suppress the splitting reflection of the filter Μ〇ΓΑ Sister; 5 rainbow d Mocho 彳 5 reflection to the active 埠.

A further additional aspect of the method relates to suppressing any MaCA signal from a combined active signal that is otherwise conducted to a non-material, by providing a combined active signal to a second MoCA frequency suppression chopper in the access adapter. The power of P / 7 and the CATV downstream and upstream signals transmitted using the passive chirp pass through the second m〇ca frequency rejection filter with substantially no attenuation. Yet another additional aspect of the present invention relates to utilizing a third M〇c^ rate suppression chopper in an access adapter without substantially attenuating the CATV upstream and downstream signals passed to and from the access adapter. Suppresses a significant portion of the power from the MqCa signal that would otherwise be conducted from the access adapter to the CATV network and would otherwise be conducted from the CATV network into the access adapter. The invention will be more fully understood and the following and other aspects of the invention can be obtained by reference to the following detailed description of the preferred embodiments.

The upstream signal 40 is delivered from the CATV access adapter 10 to the CATV ολ _u· LA LATV network 20 and is conducted to the head end 24 in reverse order. The conventional relay amplification g τ and the current amplifier 42 are scattered at appropriate positions in the topology of the CATV network, and the first and second pairs of the downstream 彳s唬22 and the upstream signal 40 are amplified. The traditional relaying female crying > 7丨,, a | upper 逻, logical amplifier can also include the online cable tap 36. Cable tap 36 and signal splitters/combiners 28 and 32 divide the single downstream signal into a plurality of separate downstream signals and combine the multiple upstream signals into a single upstream signal. The CATV Access Adapter 1() receives the downstream (four) 22 from the CATV network 20 at the CATV network connection or the access to the bee. The passive downstream signal is conducted through the cm access adapter 1 to the eMTA device 21 without amplification, enhancement, modification or other substantial adjustment. The passive downstream signal is delivered from the passive port to the passive subscriber device, i.e., by the voice data machine connected to the telephone 48. The active downstream signal is amplified, filtered, modified, enhanced, or otherwise adjusted by, for example, a power-consuming active electronic circuit component (such as an amplifier) in the CATV access adapter. The active 18 201145907 downstream # number is divided into multiple replicas and is delivered from each of a plurality of active chirps (co-labeled as 49 'but individually labeled as 50, 52 ' 54 and 56 in Figure 2 ) copy. The active downstream signal is delivered to the active subscriber device located at the subscriber premises 12. Typically, the active subscriber device will be a multimedia device 16 that is connected as part of the M〇CA network 14. However, the active subscriber device does not have to be MoCA enabled. An example of a non-M〇CA-enabled active subscriber device is an active-capable television set that is directly connected to the CATV access adapter without using the MoCA interface. In this example, a non-M〇CA enabled television set will not be part of the MoCA network 14. The CATV subscriber devices typically generate upstream signals (pictures) and pass them to the CATV interface (4) (4) for delivery to the network 2.

The CATV network connection of the CATV network 20 10 is connected to the port 44. The turns 44, 45, 50, 52, 54, 56 and 68 are each preferably formed by a conventional female coaxial cable connector that is mechanically coupled to the housing 58 and electrically connected to the internal components of the CATV access adapter 1 . Coaxial cable 18 and branch cable 38 (Fig.) from the subscriber premises cable infrastructure are mechanically coupled to form bus 44' by mechanically coupling corresponding coaxial coaxial cable connectors (not shown) on the coaxial cable. The female coaxial cable connectors of 50, 52, 54, 56, and 68 are connected to the C AT V access adapter 1 . Place a CATV Access Adapter 1 at each subscriber's premises. The number of active and passive ports 45, 50, 52, 54 and 56 is determined by the number of coaxial cables 18 that are routed throughout the subscriber premises. Although the CAT v access adapter 10 shown in Figure 2 includes seven turns, other access adapters may have a larger or smaller number of turns. The number and routing of coaxial cables 18 in the subscriber premises constitute the regulatory infrastructure for the home or subscriber premises used by the MoC A network 14 (Fig. 1). Since the CATV service provider provides the C AT V access adaptation 10 used by each CATV subscriber, it is advantageous to reduce the number of different configurations of the CATV access adapter that the subscriber may need. Among other things, this 2011 2011907 sample provides economies of scale for a large number of productions, reducing the chances of installation errors, allowing subscribers to expand and change their home cable infrastructure, and reducing inventory costs. The ability to incorporate functionality into the CATV Access Adapter 10 to provide it as a hub in the MoCA network 14 (Fig. 1) also promotes economies of scale, error reduction, scalability, versatility, and inventory cost reduction. The improved CATV Access Adapter 1 described below allows for efficient use of the eMTA device 21 and multimedia device 16 connected in the MoCA network 14 without degrading or damaging the intended functionality of the connected ε device 21. At each of the coaxial cable 18 ends of the home cable infrastructure, the cable exits 70. Those coaxial cables 18 that are not currently in use are preferably terminated with suitable termination resistors (not shown) located at the cable outlets 70 of these coaxial cables 18. However, in most cases, the cable outlet 70 of the coaxial cable 72 is connected to the m〇ca interface | Each MoCA interface device 72 is conventional and includes a controller (not shown) that is programmed to have the necessary functionality for implementing the M〇CA communication protocol. Each MoCA interface device 72 is connected between the cable outlet 7〇 and the multimedia device 16. When the multimedia device 16 creates an output signal, none of the output signals are encapsulated or otherwise included in the MoCA signal created by the M〇CA interface device 72, and then these μ〇(:α signals are passed through the home by a MoCA interface device 72 The coaxial cable 18' of the cable infrastructure is passed to the other receiving M〇CA interface 21 201145907 device 72 in the MoCA network 14 at the subscriber premises by the CATV access adapter acting as the M〇CA network hub. The MoCA interface device 72 extracts the raw output signals originally encapsulated or otherwise contained in the MoCA signal, and the receiving MoCA interface device 72 provides these raw output signals to the receiving multimedia device that is attached to the M〇ca interface device 72. The ca interface device 72 can send a management signal back to the original transmit m〇CA interface device 72 to confirm receipt of the MoCA signal and additionally provide information such as signal strength. In this manner, the MoCA signal containing the multimedia content from one multimedia device 16 passes The MoCA network 14 (pictured to another MoCA-enabled multimedia device 16 for use at its location. This mode operates, and in the traditional terminology used in the field of networking, the m〇ca interface device 72 and the multimedia device 16 form a node 74 of the M〇CA network i4. The MoCA signal is in the described manner at M (&gt The Ca network 14 is transferred between different MoCA nodes 74. Although the MoCA interface device m 罝 2 can not be separated from the multimedia device μ, but each MoCA interface is typically 并In each M〇C/powered multimedia device 16 or the bamboo beanie, τ 4 has its integral part. However, for those that do not include the built-in Mop A Α π Η* TM ' 〇 CA interface device The multimedia device 16 of 72, the separate MoCA-enabled Dream Fan 7 device, is connected to the multimedia device 16 to thereby participate in the MoCA network 14 as a node. Figure 3 shows the CATV access adapter. Internal components of the ι〇. These internal circuit components include the first multiplexer, splitter/combination 76, which splits from the access line', and receives downstream from the CATV network 20 at the terminal. No. "22. Downstream signal 22 is split into - A passive CATV downstream signal 78 that is separated from the signal component foot 77 and j 22 201145907 is split into an active CATV downstream signal 80 at another separate signal component leg 81. ..., the original downstream L number 7 8 is conducted directly in the passive signal communication path 79 to the original 埠 45 and to the device 21 via the passive 埠 45. The passive upstream signal 82 is created by the eMTA 21 and communicates via passive 璋 45 via passive signals. Path 79 is conducted to signal splitter/combiner 76 to become upstream signal 40 in the pass 2 . The passive signal communication path 79$ for passive signals in the CATV Access Adapter 1 contains active electronic components that may be malfunctioning or malfunctioning, thereby enhancing the susceptibility of CAP passive communication. Because of its use in emergency and critical situations, the passive signal path L path 79 is intended to be as reliable as possible. The voice data machine and the telephone set 48 ("Communication," the telephone communication capability is an example of the eMTA device 21. The active CATV downstream signal from the other separate signal component legs 81 of the splitter/combiner 76 is 8" In the active downstream signal communication path 85 is conducted to the CATV downstream frequency bandpass arbitrator 84. The downstream arbitrator 84 passes the signal 'with the frequency of the CATV downstream frequency range of 54_1 GG2 MHz' and the suppression has other ranges The frequency of the signal passes through the downstream 彳5 of the filter and is amplified by amplifier 86 and then supplied to a second CATV downstream frequency bandpass filter 88, which are also part of the active downstream signal communication path 85. The amplified and progressively filtered active CATV downstream signals are then conducted to MqCA frequency rejection m with a conventional configuration. The function of the frequency rejection filter 90 is by making the signal in the M〇CA frequency range 23 201145907 1 125-1525 MHz These signals cannot be transmitted through the filter 9〇. The signal in the frequency range outside the MoCA band 1 125-1525 MHz passes through the MoCA frequency suppression filter. 90. The downstream signal of CATV is in the frequency range of 54-1002 MHz, so the M〇CA frequency suppression filter 9〇 easily passes the downstream signal of CATV. After passing the MoCA frequency suppression filter 90, the frequency range is 54_1〇〇2 mhz The internal CATV downstream signals are applied to the common terminal of the second conventional bidirectional splitter/combiner 94. The splitter/combiner 94 splits or divides these signals into four identical downstream signals, each having the same downstream signal having The power or signal strength of the downstream signal initially applied to the splitter/combiner 94 is approximately one quarter. Each split signal is separated from the four separate signal component legs 91, 92, 93 of the splitter/combiner 94. One of the delivery of 95. The four split signals from the signal component legs 91, 92, 93 and 95 of the splitter/combiner 94 are applied to the active ports 50, 52, 54 and 56 of the CATV access adapter 1 respectively. Although four active 埠5〇, 52, Μ and 56 are shown, by using a splitter/combiner with a different number of signal component legs, or by using multiple cascaded splitters/combiners , achieved more Active 埠 to obtain a desired number of split signals to be applied to all active turns of the access adapter 。. The multimedia device 16 connected to the active 通过 via the coaxial cable 18 is responsive to the active 埠 50, 52 To the extent that the CATV downstream information is available at 54 and 56, each MoCA interface device 72 passes these downstream signals to the multimedia device. The MoCA interface device 72 does not modify or otherwise affect the CATV passing therethrough. Downstream signals. In those cases where the multimedia device 24 201145907 16 is capable of transmitting the CATV upstream signal 96, those catv upstream signals 96. also pass through the MoCA interface mount 72 without change or influence and then through the cable exit 70, the coaxial cable 18 And the active 埠5〇, 52, 54 or 56 is conducted to the splitter/combiner 94. The splitter/combiner combines all of the CATV upstream signals 96 and provides these signals as a combined active upstream signal 96 to the MoCA frequency rejection filter 9A. Since the catv upstream signal 96 is in the 5-42 MHz band and outside the m〇CA band of 1125_1525 _, the CATV upstream signal % is passed upstream into the active signal communication path 99 by the m〇ca frequency suppression filter 90. The combined active upstream signal % from the MoCA frequency rejection filter 9 is provided to the first CATV upstream frequency bandpass filter 98 of the active upstream signal communication path 99. The filter 98 passes a signal having a frequency in the catv upstream frequency range of 5 - 42 MHz, and suppresses the 彳§ number having frequencies in other ranges. The CATV upstream signal passed by the filter | § 96 is then supplied to the intrusion noise mitigation circuit 100. The intrusion noise mitigation circuit 1 may inflict intrusion noise in the 〇_42 MHz range from the noise source in the subscriber's premises. The use of the intrusion noise mitigation circuit 1 is optional in the CATV Access Adapter 10, but if used, it is preferably used with the title "Ingress N〇ise Inhibiting" submitted on January 13th, 2008.

Ideally, the MoCA signal in the MoCA network 14 should be limited to between the MoCA interface device 72 through the cable exit 7〇, the coaxial cable 18, the active ports 50, 52, 54 and 56 and the splitter/combiner 94. path of. #密频率抑制过滤90 has sufficient size and capability to effectively throttle and suppress substantially all of the power or intensity of the test signal present at the common terminal of splitter/combiner 94, MoCA(4) will be limited in this ideal manner . However, the M〇CA frequency suppression filter 9 which has the ability to effectively suppress and suppress substantially all of the power of the M〇CA signal is relatively costly and will require the manufacture of a large amount of material' thereby making its manufacture more difficult and expensive. And will require significantly greater manufacturing effort to tune to achieve effective MoCA frequency rejection in conjunction with establishing the bandpass characteristics of the MV 26 201145907 downstream and upstream filters 84, 88, 98, and 102. The relative nature of the filters 9〇, 84, 88, 98 and 102 in a single access adapter 1使得 makes the correct operation of each filter dependent on the correct operation of all other filters. Therefore tuning all filters becomes expensive, repetitive and time consuming iterative behavior. Typically, in the absence of substantial suppression of the M〇CA signal by the MoCA frequency rejection filter 9 Mo, the MoCA signal having sufficient strength to adversely affect the correct function of the eMTA device 2 i can be transmitted or otherwise propagated through the active The circuits of communication paths 85 and 99 interact with passive CATV upstream and downstream signals 82 and 78 in passive communication path 79. The strength of the MoCA signal propagated in this manner may be sufficient to destroy the information contained in the passive CATV signals 78 and 82 and thereby impair or hinder the proper functioning of the device 21.

A relatively large suppression filter is required. This is a misalignment: in this case the tuning of the MoCA frequency rejection filter will typically be affected by the tuning of the CATV bandpass filters 84, 88, 98 and 102. One or more additional MoCA frequencies are avoided in order to avoid the cost and complexity of fabricating and tuning a single MoCA frequency rejection filter 9 that has the capability to suppress all MoCA signals and prevent them from entering the signal communication paths 85 and 99 of the access adapter. The suppression filters 1〇4 and ι8 are incorporated in the access adapter ίο. In this case, the M 〇 CA frequency suppression filter 90 is not required to suppress the entire intensity of the MoCA signal, but instead it has the ability to suppress the intensity of a large portion of the M 〇 CA signal. The remainder of the MoCA signal strength is suppressed by one or both of the additional M〇CA frequency suppression filters.

The third MoCA 28 201145907 frequency suppression filter 108 suppresses residual MoCA signals that have passed through the _M〇CA frequency suppression filter 90, the active signal communication paths 85 and 99, and the splitter/combiner, thereby preventing these residual M〇 The CA signal arrives at the CATV network 20. In the absence of the MoCA suppression filter 1〇8, the residual Moca signal from the 'CATV access adapter 1(), as understood from Figure i, can traverse the branch thin line 38 to the horizon tap 36, and the slave cable The line tap passes the other branch cable of the cable branch 36 "to another CATV access adapter of the different CATV subscribers." Prevents residual Moca signals from reaching the adjacent subscriber premises in protecting the original CATv tenant It is important to communicate the privacy of the communication in the CA network 14 and to prevent interference with the correct functional aspects of the different CATV subscriber's MgCA network. From a similar point of view, the third MoCA suppression filter 1〇8 also prevents from another - residual MoCA signal present on the CATv network 2 of the CATV subscriber's MoCA network enters the CATv access adapter 1 at the access port 44 and issues questions regarding correct passive signal communication to and from the eMTA device 21. Therefore, the third MgCa frequency suppression chopper (10) prevents the MoCA signal from escaping from the access adapter 1() to the catv network 2q and prevents the M〇CA signal present on the CATV network 20 from entering the access adapter 1 〇.

Preferably, the combination of the MoCA frequency suppression filter is implemented... and the active bee 5. At least 60 dB of isolation between 52, 54 and 56 =. This level of isolation is achieved by determining the size of the m〇ca frequency suppression filters 90, 1〇4, and 1〇8 to achieve the desired 6〇 dB signal isolation. Since the effects of the plurality of filters are additive, the preferred method is to determine the size of each of the three M 〇 CA frequency suppression filters 9 〇, 1 〇 4 and 108 to have an isolation of at least 30 dB alone. In addition to suppressing the benefits of the m〇CA signal in the CATV signal path, the MoCA frequency rejection filter 9〇 also contributes to the strength of the M〇CA signal transmitted in the m〇CA network 14. The rejection of the MoCA frequency rejection filter 90 is achieved in part by reflecting the MoCA signal rather than absorbing the power or intensity of the m〇CA signal. The MoCA signal reflected from the MoCA frequency rejection filter 90 passes directly downstream through the splitter/combiner 94. Although the intensity of the reflected MoCA signal is divided by the splitter/combiner 94, the intensity of the split-reflected MoCA signal at the signal component legs 91, 92, 93, and 95 is added to the signal component legs 9 at 92, 93, and 95. The strength of the MoCA signal. Without the additive effect from split-reflecting MoCA signals, the strength of the MoCA signal available at signal component legs 91, 92, 93, and 95 is entirely dependent on the splitter hop. As discussed above, splitter hopping involves a significant signal attenuation of 30 201145907, thus significantly reducing the MoCA signal strength at 埠50, 52, 54 and 56. The MoCA signal that can be transmitted from the signal component legs 92, 93, and 95 to the MoCA interface device 72 passes through the MoCA frequency suppression filter 90 by adding the effect of the split MoCA signal reflected from the MoCA frequency suppression filter 90. Significantly enhanced by signal reflection characteristics. The enhanced signal strength of the MoCA signal created by reflection from the MoCA frequency rejection filter 90 also contributes to reducing the strength of the MoCA signal transmitted through the MoCA frequency suppression filter 90. As discussed above, the MoCA communication protocol has the ability to communicate information describing the strength of the received signal between the transmitting and receiving m〇CA interface devices. Low signal strength will cause the transmitting MoCA interface device to increase the strength of the transmitted signal. Without the additive effect of the split-reflected MoCA signal from signal component legs 91, 92, 93, and 95, the received signal strength received by the MoCA interface device will be due to the signal component of the MoCA signal at splitter/combiner 94. The splitter jumps between and is significantly attenuated. The reduced signal strength will be passed to the transmitting MoCA interface device and the MoCA interface device will respond by increasing the strength of the emitted MoCA signal. The increased strength of the excited m〇CA signal will not be effectively suppressed by the MoCA frequency suppression chopper 90' thereby allowing more residual m〇CA signal strength to pass through the CATV signal communication path into the access adapter. . However, by enhancing the MoCA signal strength at the signal component legs 91, 92, 93, and 95 due to the additive effect of the MoCA signal reflected from the MoCA frequency suppression filter 90, the signal strength of the emitted MoCA signal is lower, resulting in a lower Less m〇CA signal transmission and less required MoCA signal suppression to obtain the correct function of the eMTA device 31 201145907. The second m〇ca waver 104 is important when the third m〇ca frequency suppression filter 1〇8 is connected to the (10) adapter 1〇 CATV access port 44. Some portion of the residual transmitted MgCa signal is reflected from the :MoCA frequency (4) waver 1G8, and those suppressed Moca signals pass through the splitter/combiner 76 to the passive communication path 79. Thus, including the third M〇CA frequency rejection filter at the CATV access port 44 enhances the strength or power of the residual MoCA frequency conducted into the passive communication path due to signal reflection. The CATV Access Adapter 1 has a beneficial contribution to the quality of service that can be obtained from the CATV network 2 and the network 14. Even when the device u is not enabled by MoCA and the M〇CA network is established to have the access adapter 21, the correct function of the eMTA device 21 at the subscriber premises is maintained. The MoCA frequency suppression filter(s) clamps the residual M〇CA 从 from the network through the passive CATV signal communication path, thereby maintaining communication or another 6 连接 connected to the access adapter 1〇 The expected function of the device. The CATV Access Adapter 1 is fully functional as a MoCA Network Hub to deliver a sufficient strength of MoCA signals between all M〇CA interface devices and multimedia devices while maintaining the desired CATV functionality. The CATV Access Adapter also prevents or greatly hinders the nickname from reaching the CATV network, thereby avoiding the compromise of privacy and security of MoCA content that is expected to remain only in the MoCA network of the subscriber's premises. Similarly, the CATV Access Adapter also prevents or greatly prevents the MoCA signal present on the CATV network from entering the adapter and interfering with the correct functioning of the subscriber device connected to the Access Adaptor. The advantageous function of the CATV access adapter is obtained in the housing of the CATV access adapter, thereby protecting the desired benefit from unauthorized tampering, installation negligence and physical exposure. The versatile aspect of the CATV Access Adapter allows it to be used in many situations, thereby increasing its scale and economy of use and facilitating greater installation convenience for CATV service providers. The CATV Access Adapter 1 allows subscribers to more flexibly expand and change their C AT V subscriber devices and their μ 〇 C A network and multimedia devices. The significance of these and other improvements and advantages will become apparent upon a comprehensive understanding of the invention. The preferred embodiment of the invention and many of its modifications are described above in detail. This detailed description is a description of a preferred example of implementing the invention. The details described are not intended to limit the scope of the invention. The scope of the invention is defined by the scope of the appended claims.
