Method and device for data transmission

 

The invention relates to signal transmission, in particular the United containing podzagnuli corresponding to two or more different protocols on the same wire. The technical result is to provide a subscriber with a wired communication line, cheaper telephone services and data transmission. The technical result is achieved because the present invention uses the cable television network to provide access to data networks with relatively low cost, especially for use by place of residence. To create located in the house of the internal network unmodulated data signal (for example, Protocol Ethernet) are combined with the signals of cable television using a preferably passive filters and the combined signal is distributed in one or several apartments. Outgoing data is passed along the same path in the opposite direction. Unmodulated data signal may also contain a phone signal, combined with the data signal without modulation. 5 N. and 20 C.p. f-crystals, 12 ill.

The technical field to which the invention relates.

containing podzagnuli, corresponding to two or more different protocols on the same wire.

The level of technology

The main difficulty for new operators providing telephony services, is providing the communication line on the last section directly to the consumer. The laying of new cables is expensive, and therefore, a search for alternatives to leased telephone lines provided throughout the communication channel to the consumer.

For economic reasons the new cables are usually installed simultaneously with the installation of other cable systems, for example, community reception (often for the sake of simplicity called cable TV, CTV).

Currently, to provide access to the Internet around the world are starting to use modems KTV. One possibility of providing a telephony service is a connection block of telephone communication using the Internet Protocol (MP), to the modem KTV. Also developed technical solutions, in which the block of telephone connection with Internet Protocol integrated in the modem KTV. In the application WO 98/57456 A1 describes a technical solution in which the Ethernet signal and telephone signal modulated in one and thee also provide each subscriber access over the air.

All of the above technical solutions are relatively expensive. The laying of new cables in older buildings often has high value. For the implementation of other variations (modulation in the same cable modems, cable TV and access over the air), the subscriber must purchase a new device, perform a new function. This unit requires maintenance, which increases its cost. In addition, the device must be powered and, therefore, it will not work in case of disturbances in the power supply.

Currently there is a growing need for the provision of Internet connectivity from residential homes to provide opportunities to work at home and for personal use. A common solution is the use of modems and standard telephone lines. This solution has two major disadvantages: the phone line is busy during the whole period of the connection and the bandwidth is very low.

In the art it is well known the use of cable television networks (CATV) for connecting to an external data network from the building. TV signals and data, for example, corresponding to the Protocol Ascaloth and therefore, can be easily separated. In this case, each subscriber has a modem KTV, which retrieves the data signal and sends it to the subscriber computer.

Modems KTV are relatively expensive. In addition, the subscriber actually divides the frequency band located in the House on the internal network with all the other subscribers in the house because the full amount of data is transmitted to all and data directly related to each subscriber, is in its modem KTV or computer.

Others known in the art solution is to create a data separate new network, not using any one of the parts of the network. This is the standard solution in the office. For access by place of residence the cost of installation of wires may be prohibitive.

In canadian patent No. 1252169 describes a system that combines the signals KTV and demodulated data signals. The system created mainly for use in clinics, designed so that it provides a very low throughput for data transfer, sufficient to convey information about the menu, as well as information from devices, climate control and other dutchican local area networks, such as Ethernet, as it does not respond properly to the requirements for resistance with the passage of the data signal. In addition, in the canadian system, you must have the amplifiers in the transmission path.

The objective of the invention

The present invention is a method and device for relatively inexpensive connection to the data network, especially the Internet.

Another objective of the present invention is to provide a subscriber with a wired communication line, cheaper telephone services and data transmission.

The invention

The mentioned problem is solved in the present invention by a device of a transmission signal containing

the terminal for the combined signal, used for receiving the incoming combined signal and transmitting an outgoing combined signal, and the above-mentioned signal contains pilot polsignal and polsignal Ethernet,

terminal for telephone podzigyla designed to transfer an incoming telephone podzigyla obtained from the combined signal, and receive outbound telephone podzigyla,

terminal podzigyla Ethernet intended to transfer an incoming podzigyla m, it contains

the filter tool, made with the possibility of combining outgoing Podshivalov existing in the terminal for a telephone podzigyla and the terminal podzigyla Ethernet, respectively, to the output a combined signal that should be transmitted from the terminal to the combined signal,

the filter tool is made with the possibility of splitting the combined signal received by the terminal for the combined signal, an incoming telephone polsignal and incoming polsignal Ethernet, which should be transmitted from a terminal to a phone podzigyla and terminal podzigyla Ethernet, respectively.

This problem can be solved by creating a way to combine Ethernet signal and a telephone signal in a communication network, namely, that

accept outgoing phone polsignal,

accept outgoing polsignal Ethernet,

unite adopted outgoing phone polsignal and adopted outgoing polsignal Ethernet in the United outgoing signal by using at least one filter and transmit the merged outgoing signal

take the combined incoming signal containing the telephone polsignal and is walking polsignal Ethernet through the use of, at least one filter and

transfer incoming phone polsignal to the subscriber via the first terminal for podzigyla and transmit the incoming polsignal Ethernet to the subscriber via a second terminal for podzigyla.

This makes possible the unification of the Ethernet signals and telephone signals in one cable, optimising, thus, the use of network resources. Use simple filters to make the device inexpensive and robust, especially in the case of passive filters. In addition, there is no need for a power source, which makes the device corresponding to this invention, even more reliable.

According to a preferred implementation variant of the invention the said filtering means includes at least one passive filter.

Preferably the said means includes a high-pass filter, designed to receive the incoming combined signal and transmitting the incoming podzigyla Ethernet terminal for podzigyla Ethernet, and low-pass filter for the incoming United podzigyla and transfer inbound phone podzigyla in the terminal for a telephone podzigyla.

To balance the difference in resistance to the creation, located in the terminal for podzigyla Ethernet, or terminal phone podzigyla.

The technical solution of this invention also does not require installation of any additional software or hardware in computers or phones.

The currently used standards Ethernet in practice, the use of frequencies above 100 kHz.

Conventional telephone signal uses a frequency range from 0 kHz to 4 kHz. Phone signal CSCW (digital network integrated services) uses the frequency range from 0 to 80 kHz. Therefore, either a standard telephone signal, or the signal CSCW can be combined with the Ethernet signal without requiring the use of active components, such as modulators.

The present invention relates to the provision of access to data networks and, in particular, to the provision of network access data at a relatively low cost, particularly at the place of residence.

The aforementioned task is also solved according to the invention, by creating a way to distribute data using the network, namely, that

combine the demodulated data signal and the signal KTV using filters

rassada also solved, according to the invention by a device for combining and/or splitting signals CATV and data signals containing the first input terminal configured to receive signals KTV, a second input/output terminal, configured to transmit and receive a data signal, and the third input/output terminal, configured to receive and transmit the combined signal KTV and a data signal, a high-pass filter to the first input terminal, a low-pass filter in the second input/output terminal and block associations, coupled with a high-pass filter, low-pass filter and the third input/output terminal.

According to a preferred implementation variant of the invention used filters are passive filters.

This solution allows you to apply for separating/combining signals inexpensive passive components, as used unmodulated signal data.

In a preferred embodiment of the invention the demodulated data signal is a signal corresponding to the Protocol Ethernet.

The technical solution of this invention, therefore, posvyavaetsya the distribution of data, at least one computer and/or from him, namely, that in the distribution in the direction of the computer

means for receiving an incoming demodulated data signal,

means for combining the incoming demodulated data signal and the input signal KTV in the combined signal,

means for transmitting the combined signal to at least one subscriber,

means for separating the combined signal on the data signal and the signal KTV,

means for receiving an outgoing baseband data signal, at least from one computer and transfer referred to recognize the existing resources, that is, the cables are already available, which means that the network can be implemented in an inexpensive way. The method and the device corresponding to the present invention, also allow you to add new users to the network data with a relatively low cost.

For example, in a network with a hub and spoke topology, the hub of Etherner can be used to transfer the full amount of data all the apartments, and the choice of data specific to the computer that runs the computer.

In another case, the data distribution can be used the switch, then each computer are transmitted only to the data intended for the computer or computers that are included in a single chain.

In this case, users should not share the same frequency band, which means that each user can effectively use the entire bandwidth available for data transfer.

In a preferred embodiment of the invention the incoming data signal shares the incoming cable TV signal and the data signal and TV signal demodulator in modem KTV before combining the signals.

Please note that the transfer of data signals is carried out in dvorista, connected between the second input/output terminal and a low-pass filter.

In a preferred embodiment of the invention for the network Ethernet with a bandwidth of 10 Mbit/s cut-off frequency of the filters is, essentially, between 20 and 30 MHz. For network Ethernet with a bandwidth of 100 Mbit/s with a suitable cut-off frequency is 50-60 MHz.

When transmitting signals KTV resistance in the first input terminal, essentially, is 75 Ohms, and the resistance in the second input/output terminal, in essence, is 50 Ohm.

A detailed description of the preferred variants of the invention

In Fig.1A illustrates a typical network cable TV connection "star". The KTV amplifier 1 receives a TV signal, which typically is distributed from the amplifier 1 for all apartments in the house. To each TV 3 in the house or each apartment is a separate cable.

In Fig.1B illustrates a typical network cable TV connection "cascade". As before, the amplifier 11 KTV receives a TV signal, which typically is distributed from the amplifier 11 in all the apartments in the house. Several TV 13 is connected to the amplifier 11 in the same cable. For each TV 13 includes a reception unit 15, which divides the power from the amplifier in such a way that each apartment gets her part.

Of course, the possible combinations of the two configurations shown in Fig.1A and Fig.1B.

In Fig.2 shows a basic embodiment of the invention based on the network configuration. the t amplifier 101 TV signal is distributed over a number of apartments with a TV 103 and the PC 104 via a separate cable for each apartment. TV signal may also be distributed on apartments that have only one or a few TVs 105.

In this embodiment of the invention for transferring data outside of the house is an external network 107 data. Incoming data from the network 107 data are distributed in the distributing device 108 in all apartments with located in the house's internal network. Distributing device 108 may be a hub or switch, which distributes incoming data destined to each user on a separate line. The hub simply divides the signal into a number of identical signals, which is distributed to all subscribers to the same data signal. If a switch is used, the data signal intended for each subscriber may be transferred only to this user. In this case, each subscriber can use the whole bandwidth of the transmitting cable for their own data.

To allow distribution through a network KTV signal data, the organisations. Other apartments 105 do not have access to the network 107 data and directly connected with the amplifier 101 in the usual way. The device 109 fork/join takes as data signals from the network 107 data and TV signals from block 101 receiving, combines them into one signal and outputs a signal containing a data signal and a TV signal. When working in the opposite direction the device is fork/join receives the signal containing the data signal. The device of the fork/join is described in more detail using Fig.5.

Each apartment is equipped with such a device 111 fork/join. Devices 109, 111 fork/join perform the same functions, but their design may vary. For example, there may be very real to include multiple devices 109 fork/join, connected directly to the amplifier 101 and the network 107 data in one block. Device 111 fork/join on the subscriber end can be integrated into an existing device, for example, the antenna socket. Thus, each computer receives the full amount of data. In accordance with, for example, Protocol Ethernet, each computer has a capability izvlecheniye devices 108, may not be, but if there is one, it can be provided by any known in the art method.

In Fig.2 shows a separate data network, i.e. data comes in a building separate cable 107.

If the external data connection is not available, the network KTV can be used for internal communication within the building.

In Fig.3 shows a second variant of implementation of the external data connections using modems KTV. The data signal and TV signal are taken on the same line by using the bidirectional amplifier 201 by the way, which is well known in the art. From amplifier 201 only TV signal is distributed over a number of apartments (for simplicity, shows only one) with the TV 203 and personal computers 204, via a separate cable for each apartment.

The output signal from amplifier KTV also takes the modem 207 KTV. Of course, other configurations are possible. The modem 207 KTV extracts the data signal from the combined signal and sends this signal distributing device 208. Distributing device 208 may be a hub or switch, which distributes incoming data intended for each subscriber of the ordinary to make this possible used similar to that shown in Fig.2 device 209 fork/join, which combines the signal present at each of the cables connecting the amplifier 201 with TVs 203, with the corresponding data signal received from the distribution device 208. Each apartment has a similar device 211 fork/join, designed to separate the received data signal and the TV signal.

When working in the opposite direction in the personal computer 204 generates a data signal that passes through the device 211 and 209 fork/join in distributing device 208. Hence, the signal can go back through the modem 207 KTV, and after modulation (typically in the range between 5 and 25 MHz) data in the reverse direction is transmitted to the external network via the amplifier 201.

The third option for external data connections may be the Association of the data signal and signal KTV using passive components of the present invention. In this case, the device 109, 111 fork/join can be used to combine the signals.

One of the configurations, making it possible, as shown in Fig.4. On the left of the drawing shows part of the line VL is borovany the data signal and the signal KTV, United together by means of a passive component, the kind considered in more detail using Fig.5. At certain maximum distances along the route you need to install the intermediate amplifiers, which in the preferred embodiment, also perform the separation of the two signals. Each intermediate amplifier is implemented as follows. The incoming signal is divided into signal KTV and unmodulated data signal in the device 221 fork/join. The signal KTV fed into the amplifier 223 KTV, and the data signal is supplied in distributing device 225, which may be an intermediate amplifier, but can also be a switch or hub. The output signals from the amplifier 223 KTV and distributing device 225 again unite in a device of the fork/join 227.

Before the signal is fed into amplifier 231 KTV, it is divided into the signal KTV and the data signal in the device of the fork/join 229. The signal KTV is served in the KTV amplifier, and the data signal is supplied to the distribution unit 233, preferably the switch. The output signal from the switch that is designed for each apartment, again combined with the signal KTV device 234 division/ separates the signals and delivers the TV signal in a TV 236, and the data signal in the computer 237.

In Fig.5 shows a preferred embodiment of the device of the fork/join 109, 111, 209 and 211. The device of the fork/join has a first terminal 251 for receiving the TV signal, the second terminal 253 for receiving and transmitting data signal and the third terminal 255 for receiving and transmitting the combined signal. The data signal is received either from a distributing device 108, 208, or from the subscriber computer. TV signal from amplifier 101, 201 KTV. The combined signal is transmitted by the in house internal network.

Cable TV is usually transmitted at frequencies above 47 MHz. The data signals are typically transmitted using frequencies below 30 MHz. Therefore, in the first terminal 251 posted by the high-pass filter 257 for filtering data signals and transmission of the TV signal. The second terminal 253 posted by a low pass filter 259 for filtering a television signal and transmission data signal. Filters 257, 259 are connected with the block 261 fork/join, in which two signals are combined.

Resistance to three lines usually differ. In the first 251 255 and third terminals, the resistance is typically 75 Ohms. In the second terminal 263 resistance. This, however, is optional, because the difference in resistance usually does not create significant problems.

In the device 111, 211 fork/join on the subscriber end of the first terminal 251 is connected to the TV subscriber. The second terminal 253 is connected to the computer of the subscriber, and a third terminal 255 is connected with the corresponding third terminal 255 devices 109, 209 fork/join, located at the other end. The first terminal 251 of these devices 109, 209 fork/join is connected to the KTV amplifier 101, 201. The second terminal 253 is connected with the distributing device 108, 208.

In Fig.6A and Fig.6B shows the different technical implementations for apartments that have more than one television outlet. In Fig.6A, it is assumed that the television outlet is located after the outlet for the data, when viewed in the direction of signal flow from source KTV. The device 301 division receives the combined data signal and television, which ramifies in the device for separating the data signal carried by the line to the computer 303, and a television signal, which may be branched in one or more blocks 304 branching to one or more televisions 305. In Fig.6B before the/join takes the combined data signal and television and divides the signal on the data signal and the television signal, served directly to the second device 312 fork/join, but, in addition, the television signal forks in block 304 branching to one or more TVs 313.

Up to this point the discussion was based on the Protocol Ethernet 10BASE-2. If you are using another Protocol, such as 10BASE-T, instead of the inverter 263 resistance, the structure of the device of the fork/join should include the adapter and matching device.

In Fig.7 shows a preferred embodiment of the invention in application to a network connection "cascade", similar to that shown in Fig.1B and designed for data transmission in the home. As before, the amplifier 401 KTV is used to receive TV signal. From the amplifier 401 TV signal is distributed over a number of apartments, each of which has a TV 403 and a personal computer 404.

As in the variant shown in Fig.2, to transfer data outside the home uses a separate network 407 data. Incoming data from the network 407 data are distributed in the distributing device 408 in each apartment through located in the house's internal network. Distributing device 408 may be a concentration is AET incoming data what specific cascade only data intended for subscribers connected to this cascade. In Fig.7 shows two cascades. Can only be used one or an arbitrary number of stages.

To allow distribution through a network KTV signal data to each of the cables connecting the amplifier 401 TVs 403, connected device 409 fork/join. In normal conditions you use multiple devices 409 fork/join, each of which is separately connected to the amplifier, KTV and distributing device 408. Block 410 used in each apartment to receive the combined signal, dividing it into a data signal and a TV signal, the signal to the TV and the computer, respectively, the inverse Association signals together and pass them to the next apartment. Due to the configuration of the "cascade" in practice, all apartments are distributed the same signal containing a data signal and a television signal. If one or more flats, the data transfer is not required, block 410 reception can be simplified as described below.

Block 410 reception in each apartment receives a combined signal containing both data signals from from the ASI as data signals, and TV signals. When working in the opposite direction the device is fork/join receives the signal containing both the data signal and a TV signal, and divides them into two separate signal. A device for separating/combining identical considered using Fig.5.

As for the configuration with the "star" topology, data connections 407 may not be, or it may be provided by any known in the art by the way. Several different connection options data were processed using Fig.2, 3, 6A and 6b.

In block 410 reception shown in Fig.8, there are two devices fork/join a, 411b, similar to that shown in Fig.5. When working in the direction of receiving one unit of fork/join a separates the received signal into a data signal and a television signal. The television signal is transmitted through the cable 412 to another device, fork/join 411b, the block 413 branching placed in the above-mentioned cable 412, forks a signal to the TV. The data signal is transmitted through the cable 414 to the data in the transceiver 415 and from the transceiver to the other device fork/join 411b. The transceiver has a high input of soprotivlenie at a distance of only a few centimetres from the cable. The transceiver is an active component and needs external power, which under normal conditions is taken from your computer by using the interface imps (interface of the connected device). From transceiver 415 data line also branches out to map Ethernet power ICS, located in the computer (not shown).

In recent requesting data transmission apartment cascade, i.e. at the end of the cable, do not want to install a second device of the fork/join. Instead, you must set the target device to stop the passage of the data signal. For apartments, located after the last apartment, participating in data transmission, can be used the usual cascading TV network, since the data signal is not used for re-unification in recent requesting data transfer to the apartment.

If one or more flats, the data transfer is not required, the device of the fork/join a, 411b are still required for all apartments, located between the amplifier 401 and apartments, which must be able to accept data. Therefore, they can be installed units receiving such unit 410 shown in Fig.Nem stage, you must install the transceiver. Another option can be installed complete unit 410 reception and receive data from the transceiver may be blocked. Of course, it would be convenient technical solution that could allow remote activation and deactivation of the data. This can be done using control packets Ethernet, in this case to test control packets in the apartments will need to install additional hardware.

Alternatively, the transceiver 415 in Fig.8 may be replaced by an intermediate amplifier or a small hub or switch. In the art known hubs, enabling them to use as a Protocol 10BASE-2, and the Protocol 10BASE-T. the Output 10BASE-T such a hub should be connected with an external computer, while the output 10BASE-2 must be connected to the inner coaxial cable 414. Because the Protocol 10BASE-T distributed much more widely than 10BASE-2, this solution may be more advantageous. Distribution block (intermediate amplifier, either a hub or a switch) needs a power source, but even if one distributes bolthouse transceivers, as explained above.

For practical reasons, distribution blocks, that is, hubs or switches, in dwelling units must be powered from the cable KTV. To make this possible, together with the data signal and TV signal distribution blocks can be supplied with constant current or alternating current of low frequency. To separate the data signal, TV signal, and power is then used three-pass filter. Such three-pass filter is also used for re-combining signals for outgoing cable, CTV.

Instead of a transceiver in the system can use a hub or switch 10BASE-T. In this case, the output hub or Ethernet switch, located next to the KTV amplifier must be installed for matching devices to switch with cables of twisted pair to coaxial cables. In this case, the matching device must be used for each role in each apartment. This configuration is much more sensitive to disturbances in the power supply, because if one hub fails, it will disable the rest of the network. Therefore, the power to the hub must be connected from the cable To the use of switches, this restriction does not.

Of course, since according to the Protocol Ethernet, the computer is able to choose which items to take and which to discard, each apartment may be more than one outlet for the computer, which is located between the two devices fork/join from the same pair, or use more than one pair of devices fork/join.

The device of the fork/join can be used with great advantage, if instead of the pure signal Ethernet served a combined signal from the signal Ethernet and phone signal. Device for combining signal Ethernet and phone signal shown in Fig.9.

In Fig.9 shows part of a communication network containing the last section of the line to the subscriber, i.e. the cable that is dedicated to one specific subscriber.

In place 501 where the subscriber has a first device 503 filter corresponding to this invention, is made capable of receiving the terminal 505 to the combined signal from the network, while the combined signal contains pilot polsignal and polsignal Ethernet. Device 503 filter includes a low pass filter 507 and the high-pass filter 5 is t telephone signal, which comes first terminal 509 for podzigyla. The high-pass filter 508 receives the combined signal from the terminal to the combined signal and allocates polsignal Ethernet, which is transmitted from the high-pass filter to the second terminal 511 to podzigyla. Device 503 filtering performed also with the possibility of receiving from the subscriber telephone signal and the Ethernet signal through the first terminal 509 for podzigyla and the second terminal 511 to podzigyla respectively. Podzagnuli taken from a person, are combined in the device 503 filtering the combined signal, which is transmitted through the terminal 505 for the combined signal device 503 filtering in the network.

In the network, usually attached through an Ethernet switch, placed second device 513 filtering, the device 503 filter located in the location of the subscriber. The device 513 filter contains a terminal 515 for the combined signal, used for receiving the combined signal from the subscriber 501 and dividing the combined signal on podzagnuli, and to transmit the combined signal to the subscriber 501. The device 513 filter also includes a third terminal 519 for podzigyla intended for receiving telepole Ethernet from the network data. The terminal 519, 521 to Podshivalov also used for transmission of the corresponding Podshivalov obtained from the combined signal received from the subscriber in the network. It should be noted that the device 503 and 513 filtering perform the same function, but only in different places of the network and, therefore, can be identical.

Phone polsignal can be in any standard public switched telephone network using, for example, in the standard TOOTS (traditional telephone services), which uses frequencies up to 4 kHz, or in the standard CSCW, which uses frequencies up to 80khz, or, of course, represent any other type of signal in the frequency range of 0-100 kHz. The signal TOOTS has a maximum frequency of approximately 4 kHz, and the signal CSCO has a maximum frequency of approximately 80 kHz. Device 507, 517 filtering should split the signal between the maximum frequency telephone signal and the actual minimum frequency signal Ethernet, and it is 100 kHz.

Polsignal Ethernet can refer to any type of signal Ethernet, which uses a lower frequency, such as Ethernet with a bandwidth of 10 Mbps, for example, 10BASE-T, 10BASE-2 or 10BASE-5, Ala 509, 519 phone podzigyla, accepted by cable of twisted pairs. The data signals received in the terminal 511, 521 for podzigyla Ethernet, accepted for two (or four) twisted pairs or coaxial cable, depending on the standard. The connection between the two devices 503, 513 may provide a coaxial cable or twisted pair. To balance the resistance between the terminals, the terminals 509, 519 phone podzigyla, terminals 511, 521 for podzigyla Ethernet or both in those and other can be used for matching devices that are known in the art.

If the cable between the two devices 503, 513 is coaxial, telephone signal must be re-balanced using a matching device is attached to a terminal 509, 519 phone podzigyla. In the case of networks Ethernet 10BASE-2 and 10BASE-5 to terminal 511, 521 for podzigyla Ethernet termination device is not necessary. In the case of network-Ethernet 10BASE-T and 100BASE-TX terminal 511, 521 for podzigyla Ethernet termination device must be installed. Matching device for terminal 511, 521 for podzigyla Ethernet as a balancing resistance, and performs the lane is Abel between devices 503, 513 is a cable SET (cable category 5 unshielded twisted-pair) twisted pair LAN terminal 509, 519 phone podzigyla matching device is not required. For 10BASE-2 and 10BASE-5, which use coaxial cable, polsignal Ethernet first re-balanced using a matching device is attached to the terminal 511, 521 for podzigyla Ethernet. For 10BASE-T and 100BASE-TX, which use two pairs in the cable SET, the signal of only one pair is filtered and combined with the phone signal.

In the typical case shown, the line combines the signals received from the Ethernet network and the telephone network, the second device 513 filter and transmits the combined signal at the location of the subscriber, in which the signal is divided in the first device 503 filtering. However, it is possible that both the filter unit 503, 513 served subscribers, or both of these devices served by the network.

In Fig.10 shows a particularly convenient embodiment of the invention, in which one device 603 filter similar to that shown in Fig.9, is installed in the location of the subscriber, and the other device 613 filter similar to that shown in Fig.9, is installed in the network preferably Radome of the corresponding device 603, 613 filtering, in turn, is combined with another signal, such as signal KTV, filtration devices KTV/Ethernet 605 and 615, respectively. The filter unit KTV/Ethernet-like devices, fork/join, shown in Fig.1-8.
