Definitions
- the present invention relates to a possibility to localize a telecommunica- tions terminal over a local area network. More specifically, the invention provides a method for associating a port number of a powering equipment to which will be connected a telecommunications terminal with some identification characteristics of said telecommunications terminal. Furthermore, it provides a telecommunications terminal to be connected to a local area network while being localized when remotely powered. It provides also a supervisor engine like a server connected to a local area network and collecting identification characteristics of a telecommunications terminal for its localization over said local area network.
- a device supports a MIB if the device is capable of supplying the type of information defined in the objects specified in the MIB. Most devices can provide the type information defined in the objects specified in certain standard MIBs, known as MIB I and MIB II. The format and layout of MIB II is specified in Request for Comments RFC 1213. Additional standard MIBs have been defined for information types not covered in MIB I and MIB II, and new MIBs are being developed on an ongoing basis. However, support for these standard MIBs varies from device to device. A device may only support a subset of their own proprietary MIBs, and many devices operate in more than one mode.
- test instrument for testing a LAN.
- This test instrument once connected to that LAN, will conduct a segment discovery test in which the network devices are analyzed to detect local hosts, switches, routers, bridges and other devices, and further determine addressing information such as IP addresses, MAC addresses.
- a data base of these addresses of the various devices can be compiled.
- the type of reports chosen depend on the contents of the set of available MIBs as well as the particular ports selected for analysis.
- a switch typically has ports as listed according to the bridge MIB and also has interfaces which correspond to ports but may also include the backplane and SNMP agents. If the bridge MIB is available from the switch, the test instrument can obtain a list of MAC addresses of devices attached to any port. These MAC addresses are then matched by port against the data base to obtain the report of IP and MAC addresses and device names by port.
- This object is attained by a method for a localization of a telecommunications terminal over a local area network according to claim 1 . Furthermore, it is attained by a telecommunications terminal to be connected to a LAN according to the claim 9. And it is also attained by a supervisor engine connected to a LAN according to claim 10.
- Such a typical Ethernet connection of a telecommunications terminal to a LAN is usually based on the use of half of the 8 wires of a line L separated on two unshielded twisted pair of wires giving one pair for transmission Tx, one for reception Rx.
- the transmission pair is dedicated to send packets of data over the Ethernet connection; the reception pair receives packets of data over the Ethernet connection.
- the four other wires are usually let unused.
- a remote powering of that telecommunications terminal will be performed via center taps using these two pairs of wires of the line L as conductors of a phantom circuit.
- the power will be supplied by the powering equipment like a power patch panel to which will be connected said telecommunications terminal to the LAN. But at first, the line L of that telecommunications terminal has to be plug in using e.g. some RJ45 plug into a port of the powering equipment. Then, some recognition of the power class of the terminal will have to be performed by that powering equipment. And only then, a remote powering of that terminal will be able to take place.
- This remote powering can be advantageously utilized for the transmission of some identification characteristics of the telecommunications terminal to some supervisor engine of that LAN.
- On that supervisor engine will run an application performing some association of some identification characteristics like the MAC address of each of the telecommunications terminal with the respective port of the powering equipment via which these telecommunications terminals will be connected to the LAN.
- This association can then be let available to some telecommunications emergency application for a localization of a telecommunications terminal when activating an emergency call.
- Fig. 1 is a schematic view of a local area network-
- Fig. 2 is a flow diagram showing the different steps of the method according to the present invention.
- On fig. 1 is shown a LAN 1 to which is connected a telecommunications terminal like an IP phone 2 via a powering equipment e.g. a power patch panel 3 which may be part of a switch since being possibly inserted in it.
- a supervisor engine like a Private Branch eXchange PBX 4 is also connected to said LAN and devoted to supervise among other a correct remote powering of the different telecommunications terminals using the powering equipment.
- Some emergency application 6 not necessarily running on the same supervisor engine is able to collect the necessary information out of the PBX 4.
- An initialization of an IP phone following its plug in in the wall plug or after a restart of some installation (or part of it) will include the following main steps:
- an initialization procedure is started on said power patch panel of the IP phone, said initialization comprising possibly a recognition of the power class of said IP phone.
- the result of this initialization procedure is transmitted towards the telephony application at the supervisor engine (PBX) preferably in SNMP. It comprises the port number of the power patch panel to which is connected the IP phone. If needed, the power class of said IP phone may also be transmitted to the telephony application.
- PBX supervisor engine
- the telephony application performs some controls on the power patch panel preferably in SNMP.
- the supervisor engine will receive different events containing the different port numbers corresponding to each telecommunications terminal.
- the supervisor engine (here the telephony application on the PBX 4) will start an initialization of a remote powering of each of these telecommunications terminals one after the others via at least one powering equipment. It is conceivable that the supervisor engine controls several powering equipment while to each of them are connected several telecommunications terminals. The supervisor engine will not start with a new initialization before at least receiving some identification characteristics of the telecommunications terminal to which a remote powering will be started at last.
- a telecommunications terminal like e.g. an IP phone or an IP wireless base station after a start of its remote pow- ering, will have to transmit its identification characteristic like its MAC and optionally IP addresses to the supervisor engine i.e. the telephony application running on the PBX 4.
- This dialogue may occur using TCP/IP via path P2.
- some supplementary information may also be let available to the emergency application. Indeed, for a correct geographical localization of a telecommunications terminal, it may be of importance to have a ca- bling map which gives the physical location of the wall plug behind each port number of each power patch panel.
- E.164 addresses a scheme to assign a number to a phone line, especially for ISDN
- IP addresses a scheme to assign a number to a phone line, especially for ISDN
- MAC addresses a help for the association al- lowing an unambiguous geographical localization of the telecommunications terminals.
