Description

Technical field of the invention:

The The present invention relates to a power supply distributor a variety of ports for the connection of devices over their corresponding compounds, with at least some of these Ports over their corresponding media data interface connected to a power supply. In addition, the invention relates a method of transmission data in phantom mode using at least one Power distribution manifold with a variety of ports for connection of devices over their corresponding connection. The invention relates more generally seen a network of a variety of interconnected Node and a method for designing such a network type based on the use of phantom mode for transferring data to at least a part of the connections that the different nodes of this Network together.

Background of the invention:

The Growth of the Internet and the like LAN and metropolitan networks (Local and Wide Area Networks) based on Ethernet technology has created a potential market for the connection of telecommunication systems directly to such networks. A typical Ethernet connection with A telecommunications system at an office location is usually based on the use of half the eight wires a line L, divided into two unshielded twisted Line pairs ("twisted pair") for each one Pair to send (Tx) and a pair to receive (Rx). The transmission pair is dedicated to sending data packets over the Ethernet connection used; the receiving pair receives Data packets about the Ethernet connection. The four other wires will not normally for the data transfer used, could however in similar Be used.

In the IEEE Committee 802.3 (Ethernet), an 802.3af project has been set up to remotely power data terminal equipment (DTE) connected to an Ethernet interface, ie a DTE powered by a media-independent MDI interface In this project, the possibilities and feasibility of remote terminal power supply over central branches are discussed using two pairs of lines of line L as conductors of a phantom circuit US 6,115,468 An Ethernet device power supply system is described for supplying telecommunications terminals, such as Ethernet telephones and associated devices, with electrical power over a 4-phase Ethernet connection. This is achieved without rewiring buildings that already have an existing 4-phase Ethernet system. This system includes an input transformer, an output transformer and a pair of twisted pair conductors. The input transformer includes a pair of primary terminals for connection to a source of Ethernet data. The input transformer also includes a pair of secondary terminals each having a central tap. A first twisted pair conductor is connected across the first secondary terminal, a second twisted pair conductor is connected via the second secondary terminal, and a DC bias voltage is provided between the corresponding central branches of the first and second secondary terminals. At the local end, the output transformer includes first and second centrally branched primary terminals, and first and second secondary terminals for connection to the loader. The first and second primary central branches are connected to a current processor for the extraction of direct current.

In EP1100226 For example, a more specific method for providing a remote power supply to a telecommunications terminal via an Ethernet connection will be described. Prior to transmitting a supply current over this connection, at least one detection signal is applied to at least one of two conductors of that connection to detect if there is a telecommunications terminal adapted to receive a remote power supply. By applying such a method, all risks to such terminals are avoided since the remote supply stream is sent only if the terminal has been identified as having been adapted to receive a remote power supply. The strength and duration of the detection signal is chosen so that the process of detecting the terminal can not cause any harm in the case of a terminal that is not adapted to receive a remote power supply.

In another, in US 5,555,274 Similar development may be used to construct a phantom data link (out of band data link) for performance monitoring information. It enables central offices and remote locations of telephone subscribers communicate with each other over existing telephone lines without affecting the telephone communication sent over the lines. In US 6,147,963 For example, the use of such a phantom data link for transmitting and receiving DC-balanced data sample signals is described. This allows the distribution of current through the phantom circuit as well as data under the control of a continuously variable clock. In this way, all devices connected to such phantom data connections can be synchronized.

In WO 00/41496 describes the application of a remote power supply in a local area network. Such a network includes a hub, a plurality of nodes, communication cabling for connecting the plurality of nodes to the hub for checking the data communication, and a power distribution manifold that may be used to connect at least a portion of the operating power to at least some of the plurality of nodes via the communication cabling. The hub includes a data communications concentrator connected to each individual node via a communications power combiner. The data communications concentrator is provided for transmitting data over the cabling to all nodes while the combiner provides power to all nodes via the cabling. This combiner managed power management is controlled by a few electrical gates that are activated by a controller. The latter receives the control input from a sensor, which can be implemented in many different ways. One of these options is the detection of a control signal sent by the power management in phantom mode via the communication cabling.

Summary of the invention:

task The present invention is the transmission of information as a broadcast to a device connected to a local area network to enable without existing data transfers disturb and without the need for new specific cabling.

According to one First aspect of the invention, this object is achieved by a power distribution manifold, which has a variety of ports for connection of devices over their corresponding communication links while at least some of these ports over their corresponding media data interface connected to a power supply. This power supply distributor includes modems attached to at least some of these media data interfaces are connected to process data in phantom mode via appropriate Transfer communication connections be, these modems over a multiplexer are connected together.

Furthermore the task is fulfilled by a method of transmission data in phantom mode using a power distribution panel according to the first Aspect of this invention. The method is based on the following Steps: Receive data in phantom mode on a port of a device over their communication connection; Processing this data through the Modem connected to the media port of this port; Forward this data to this multiplexer for broadcast forwarding to other connected modems; Forward this broadcast data from the modems to the media data interface of the corresponding ones Ports to let them over Communication connections in phantom mode continue to those connected to these ports Devices can be forwarded.

According to one second aspect of the invention, the object is achieved by a network that has a multiplicity of interconnected nodes comprising at least one of these nodes, a power distribution distributor according to this First aspect of the invention is attached.

The Connection of devices such as IP telecommunication terminals with a network over one 4-phase Ethernet-like Connection is used in an advantageous manner. This wiring in conjunction with central branches allows feeding and capturing a signal from a frequency modulation using the head of the Cabling as a phantom circuit. The use of a power distributor according to the present Invention at a node of such a network does not allow just controlling the remote power supply at many different Devices, but also allows the transmission data in phantom mode.

According to one embodiment of the invention, the data received at one port of this power supply distributor in phantom mode are broadcasted by a multiplexer to at least some of the other ports, so that the corresponding ones are connected to this power supply distributor This device, which can extract data in phantom mode, receives this data. This provides a way to send data to various devices connected to this network using phantom mode. This embodiment is not necessarily limited to a device having a remote power supply. It can be used as a backup application to locate the subscriber location during an emergency call.

In another embodiment According to the invention, this multiplexer is set up with a switching function. This makes possible the selection of the ports to which the data received in phantom mode be forwarded, in an advantageous manner. This way you can a telecommunication between many different, with the network connected devices, wherein the power supply distributor connected to the network and being this telecommunication exclusively based on data in phantom mode. It is also conceivable that a such telecommunications in a bidirectional mode between at least two devices.

The Use of the present invention offers the possibility by using a power distribution board and by the transmission data in phantom mode to design a new network - a ghost network - which is not assigned to an existing network necessarily has all connections of this network. These Data should be in accordance with a first aspect of the invention to specific compounds using a power distributor are taught. These transmitted over such a network Data is independent from the transmission data in Ethernet mode. It can However, gateways that contain an interaction between the Allow Ethernet network and the ghost network.

By the use of such a ghost network exists further the possibility, the remote power supply of various classes of devices to optimize as well as update this when using a device added in this network or changed has been. It can therefore even serve as a back-up channel for the various devices can be used without adding weight to the Ethernet network. This Ghost network can even for the transfer of tracking information on an emergency call (911 service in the US, 112 service in Europe) be used.

Further Advantageous features of the invention are defined in the dependent claims and will be apparent from the following descriptions and drawings.

Full Description of the preferred embodiments:

1 shows a schematic representation of a network 10 according to the prior art. A private branch exchange (PBX) 1 is available for telephony applications. The latter can also be implemented in a server, with most of the typical services of PBXs implemented. The PBX 1 as well as another server 2 are with a first switch 3a connected to the several second switches 3b are connected. To these different second switches 3b is a variety of devices such as IP-based ("Internet Protocol") terminals 5 and PCs ("Personal Computer") 6 connected. The IP terminals 5 can be powered via remote connections via a power distribution console 4 to which the communication links from the switch 3b are connected before these different devices 5 be connected.

The communication links between the switches and the various devices 5 . 6 in 1 are, for example, point-to-point Ethernet connections (10BaseT, 100BaseT, 1000BaseT). The switches 3a . 3b could also be a bridge, a hub, a router or, more generally, a network element, the differences being mainly in the protocol used for data transmission, ie the work plane (layer 1, 2 or even 3 of the OSI reference model). It might even be considered to build a similar network based on a Token Ring / FDDI principle.

In a network like the one in 1 shown, the remote power supply is performed by the power console PPP4, which is the various IP terminals 5 Powered via a corresponding phantom circuit of the telecommunications connections of the devices. The one of the network elements 2 . 3a . 3b or even the PBX 1 data sent is from the PPP 4 not impaired. This is true even for data sent in phantom mode, as these are generated from a DC modulation that can be added to the power supply very easily. Actually, the PPP 4 for the data at the connections of the network 10 "transparent".

The use of phantom mode for the transmission of data together with some sort of PPP 4 as known in the art allows only the forwarding of data in such a mode from connection to connection to the device, without the ability to broadcast to different devices or to distinguish between the different ones to those PPPs 4 connected devices.

In contrast, the use of a power distribution manifold according to the invention allows the definition of a new transmission scheme between different devices connected to the network. In 2 is a network described with a private branch exchange (PBX) 1 and a server 2 corresponding to the communication link 21a and 22a to a network element 20a are connected. Latter 20a is a combination of a switch and a power distributor that form a PPP. To this network element, other network elements are connected in a tree structure. Two 20b These network elements further form a combined with a switch power distribution. They are over the path 21b with the first network element 20a connected. One 3b This network element is one over the path 22b connected single switch. With this switch 3b are typical terminals connected, which can not be supplied via a remote connection with power, such as PC 6 , With the network elements 20b , which include a power distribution board, are connected to devices that can be powered by remote connections, such as an IP telephone 5 , a webcam 7 or a DECT base station 8th ,

• • Lokale Stromversorgung (mit möglicher Sicherung) für den Eigenbetrieb und für die Versorgung der angeschlossenen Vorrichtungen hinter den Ethernet-Verbindungen;
• • Schaltungen für die ferne Einspeisung von Strom über das Phantom-Leitungspaar;
• • Logik für die korrekte Kennzeichnung der angeschlossenen Vorrichtungen;
• • Steuerungseinheit für die lokale Verwaltung der Bausteine und für den Konfigurationsdialog mit mindestens einem spezifischen Server in den Räumen des Kunden.

The power supply function may be incorporated in a new generation of Ethernet switches, but legacy systems may be considered: in this particular case, the power supply is implemented in a specific box normally called a power patch panel ", PPP), which performs mid-range insertion (at the central branch.) A power console includes:

• • Local power supply (with possible fuse) for own operation and for the supply of the connected devices behind the Ethernet connections;
• • circuits for the remote supply of power via the phantom line pair;
• • logic for the correct identification of the connected devices;
• • Control unit for the local administration of the blocks and for the configuration dialog with at least one specific server in the rooms of the customer.

The network as in 2 which may be a typical LAN, comprises four different types of communication links, all based on the physically same type of line, ie 8 wires, normally only half of which are used for data transmission, in two separate unshielded ones twisted pair pairs. The more classic connections of such a network are the connections 22a - 22c that transport only Ethernet data. These connections are used for the connection between different network elements like the servers 2 and the switches 3b used. The same type of connection is used for the terminals, never over a distance be supplied with electricity.

Another type of communication connection 21a . 21b is the one who has the PBX 1 with the network elements 20a . 20b connects and which comprises a power supply distributor according to the invention. At such a connection 21a . 21b the normal Ethernet data is transmitted as well as data in phantom mode. The use of a power supply distributor according to the invention, for example on the network element 20a , allows selection of downlink connections to which data is forwarded in phantom mode. At the last level of the tree structure of this network are two more connections 23 . 24 , One of these links connects a device such as a webcam 7 which is powered remotely without transmitting data in phantom mode. Such a device may not have the necessary means for extracting data in phantom mode from a communication link, ie, it is usually a modem connected to a central branch. The last type of four links connects devices that need to be connected to the network, which are to be powered by remote connections and extract the data in phantom mode. These are typically IP phones or DECT base stations 8th ,

3 shows a block diagram of a power distribution according to the invention. All individual communication lines are on the distribution panel of the power distribution board to the various ports 41 . 42 . 43 connected. In the illustrated case, the power supply distributor comprises n + 1 ports for all line interfaces or media data interfaces MDI 44 . 44 ' , At least some of these ports are via an electrical connection 52 at the MDI 44 with a power supply 51 connected. Usually, such electrical connections 52 performed with the two pairs of conductors Tx, Rx with central branches of a phantom circuit. This is a remote power supply to the ports 41 . 42 connected device possible.

A key feature of the power distribution board is that few of its ports 41 . 42 about their corresponding MDI 44 with a modem 53 are connected 55 while these modems communicate with each other via a multiplexer 54 are connected 56 , In 3 is further shown that this power supply distributor a central processing unit CPU 60 includes, to which a bus 61 connected. The multiplexer 54 as well as the modems 53 are via an appropriate connection 62 . 63 with this bus 61 connected. This offers the possibility of controlling the modems 53 and / or the multiplexer 54 from the CPU 60 out. The CPU can be controlled locally via a device that has a specific port 43 is connected to the power supply distributor, with its line interface n + 1 a direct connection 64 having the CPU. This offers the possibility of a local activity at the multiplexer 54 and at the different modems 53 , Another connection 65 can the different MDI 44 with her bus 61 connect. This connection can be used to control the MDI 44 and thus used for the remote power supply. The protocol used here can be based on the Simple Network Management Protocol SNMP, the basis for normal network management software.

At least some of the ports 41 . 42 (Line interface 1 to n) of the power supply distributor can via a connection 34 that directly with the appropriate MDI 44 connected to the ports 33 a network element to be connected, here a switch (switch interface 1 to n). This connection 34 is dedicated to data in Ethernet mode only.

4 shows a schematic representation of the console of a power supply distributor 4 ' according to the invention together with the console of a switch 3 , The entire communication lines 41 . 42 which interconnect the devices or nodes of the networks terminate on a separate port 44 of the power distribution board. A communication line 41 is defined as an uplink while the others are downlinks 42 are defined. The difference between upward 41 and downlink can best be described with reference to the tree structure of the network 2 , An uplink of a network element 20a . 20b , which is a power distribution distributor according to the invention and which comprises a switch, is a connection from the private branch exchange or the server with the telephone application 1 or another similar network element 20a at a higher level of the tree structure. In phantom mode, this connection provides at least synchronization patterns and broadcast information, which is relayed from the power distribution distributor to the downlinks. The downlinks are those that form the actual tree structure of the tree network and thus another network work item 20b connect or end at the other terminals connected to the network.

In 4 not shown is the communication line 43 for a local control of the main features of this power distribution board 4 ' , In fact, a power supply distributor, ie its multiplexer ( 54 in 3 ) via its CPU ( 60 in 3 ) are controlled not only locally, as already described, but also via a remote connection. The commands are defined with a protocol that is usually based on SNMP and embedded in Ethernet data over the uplink 41 or a downlink 42 be transmitted with the power supply distributor. This is possible if the CPU ( 60 in 3 ) directly with the MDI 44 the corresponding connection 41 or 42 is connected, at which the data is received, as in 3 by bus 61 and 65 ,

The known features of a power distribution distributor are: Checking whether the connected devices actually have a remote power supply require or not, by examination their specific signature before the actual start of care these devices with electricity; Review the operations to connect and disconnecting the connections at their various ports; feeding the device phantom mode; Communication with a management server via an Ethernet connection.

According to the invention become current signals over the phantom pair between the power supply distributor PPP and the connected to this network terminals or between different PPP modulates / demodulates, or a bidirectional out-of-band channel provide. This and the multiplexer feature allow you to build a second "overlay" network - the ghost network - that can be used in conjunction with the the topology (the tree structure configuration) of the underlying different Ethernet network.

The Ghost network according to the invention based on: i) transmission data in phantom mode, point-to-point between adjacent ones Devices of the network (eg, switch or transition devices such as Terminals); ii) passing on relevant information through the power distribution board according to the invention for providing a connection between non-contiguous devices this Network. The processing of such additional information may Use the SNMP protocol if it is for an administration task selected has been. The ghost network is plesiochron, d. H. it includes several digital synchronous circuits with different clock frequencies work. The synchronization is preferred by a network element provided as a centrally connected to the LAN point is defined. Various such central points can be added Backup purposes are defined.

5 shows an example of coexistence of data and ghost network. As in the previous example 2 is a private branch exchange or a server 1 which comprises the telephony application with a power distribution distributor 4a connected according to the invention and with a switch 3a combined. In a tree-like architecture are different network elements - which in this case all a combination of a power distribution box 4b with a switch 3b form - further with the first power supply distributor 4a connected. Different devices such as IP phones 5 or PCs 6 or server 9 are also with these power distribution boxes 4b connected. The Data Subnetwork (IP) is defined by connections that are called dotted lines 30b are shown. The ghost network is defined by connections that are shown as solid lines. It is clear that two different networks can be designed with the same cabling.

• • unidirektionale Übertragung, wobei die Informationen von einer zentralen Stelle aus im Broadcast-Verfahren an alle Zweige des Baums übertragen werden. Dies ist der Fall für die Synchronisation und die Audio-Broadcast-Übertragung;
• • bidirektionale Ping-Pong-Übertragung (siehe 6): Daten werden alternativ in Auf- und Abwärtsrichtung übertragen mit Leerlauf-Perioden entlang der Zeitskala dazwischen. Zusätzlich zu den bei der unidirektionalen Übertragung beschriebenen Diensten bietet dieser Betriebsmodus ergänzende Dienste wie beispielsweise ein Overlay-Schaltungsvermittlungsnetzwerk, Ortungsinformationen bei einem Notruf (911-Service in den USA, 112-Service in Europa), Wartung, etc.

Two different transmission schemes can be offered, depending on the services to be implemented:

• • unidirectional transmission, where the information is broadcast from a central location to all branches of the tree. This is the case for synchronization and audio broadcast transmission;
• • bidirectional ping-pong transmission (see 6 ): Data is alternately transmitted up and down with idle periods along the time scale in between. In addition to the services described in unidirectional transmission, this mode of operation provides supplementary services such as an overlay switching network, emergency call location information (911 service in the US, 112 service in Europe), maintenance, etc.

An example of ping-pong transmission for plesiochronous signals can be found in 6 ,

Such ghost networks used in bidirectional transmission schemes, for example, allow the transmission of typical delay measurements that occur in the transmission of data in Ethernet mode at specific links. The big advantage of using a ghost net plant according to the invention in this case is that this is not at the expense of transmission of data in Ethernet mode. The transfer of data in phantom mode is completely independent of the transmission of data in Ethernet mode. There will be no interference even if the rate of transferring data in phantom mode is in the range of several megabytes per second.

• • eines physischen Mediums;
• • eines Synchronisationssystems;
• • eines Kommunikationsprotokolls.

The use of the architecture described above ( 2 or 5 ) and a classic frame / multi-frame organization allows you to build the ghost network during deployment:

• • a physical medium;
• • a synchronization system;
• • a communication protocol.

The physical medium uses the existing Ethernet pairs over which the feed of the phantom stream is modulated. The synchronization system will over implemented a centralized device that allows the transmission of frame and Arranged multi-frame words.

It can numerous different devices or devices to the End of the connections are connected: Ethernet phones, d. H. IP Phones, Radio Base Stations (eg DECT), Small PBX, etc. All these devices can the means required for modulating, demodulating, Interpret and process the transmitted through the ghost network Signals. this makes possible two different types of connections (ethernet and phantom) and therefore access to two different networks.

When Example possible a function of the ghost network the broadcast transmission of background music. Another feature allows you to connect a usual Telecommunications system (circuit mode). In such a case the connection line (T0 or T2) is changed so that it connects to the ghost network can be connected for communication transmission in circuit mode to the public Network without affecting the LAN and without expensive Devices for protocol changes required are.

• • für jede Nebenstellenanlage über TCP-IP-Kanal die verwendeten Kanalnummern;
• • für jede PPP über SNMP-Kanal die erforderlichen Informationen für das Einrahmen/Entrahmen von Zeitfenstern nach der Konzentration zur Weiterleitung an den Zielort.

Various private branch exchanges can be connected to the ghost network; In this case, channels must be reserved for each private branch exchange. The call server establishes permanent or temporary connections by making the following associations:

• • For each private branch exchange via TCP-IP channel, the channel numbers used;
• • For each PPP over SNMP channel, the information needed to frame / de-frame time slots after concentration for onward routing to the destination.

• • PPPs haben eigene Batterien für sich selbst und für die Telefone;
• • die Server- und externen IP- oder ISDN-Netzwerkschnittstellen haben ihre eigene Backup-Stromversorgung;
• • zusätzlich zu den derzeit vorhandenen Mitteln umfassen die Telefonendgeräte mithilfe der vorhandenen Mittel in der Ethernet-Verbindung auch Mittel zum Empfangen und Senden von Kommunikationsinformationen über Phantom-Verbindungen.

The call server also indicates to each power distribution distributor PPP via SNMP channels the relevant port numbers for establishing the required connections. These features allow you to offer mux and / or demux functions in each power distribution box with its multiplexer. An important feature of a telephone system is its autonomy against a power failure. Currently, this feature is not available on data networks. Some new architectures that use data networks to provide voice-over-IP capabilities do not provide autonomy over a power outage. The proposed ghost network allows recovery of a particular level of autonomy when using IP telephones that are powered remotely and when organizing the network appropriately:

• • PPPs have their own batteries for themselves and for the phones;
• • the server and external IP or ISDN network interfaces have their own backup power supply;
• • In addition to the resources currently available, the telephony terminals also use the means available in the Ethernet connection to provide means to receive and send communication information via phantom connections.

The ghost network autonomy allows for the provision of some services in case of malfunction of the data network to set up internal and / or external calls.
