  • Modern switching centers in the digital electronic dialing system are already able to provide the subscriber with high-bit-rate data transmission services in the xDSLJx Digital Subscriber Line in addition to the analog or digital telephone services in the POTS (Piain Old Telephone Service) or ISDN (Integrated Services Digital Network) system ) Procedure.
  • POTS Personal Telephone Service
  • ISDN Integrated Services Digital Network
  • a data transfer rate from the exchange to the subscriber (data downstream) of up to 8 Mbit / s and from the subscriber to the exchange (data upstream) of up to 640 kbit / s is possible ,
  • the interface between the subscriber and the switching center or the data transmission network on the switching center side is the line module (also line card or SLMI, Subscriber Line Module Internet).
  • the interface is formed by an xDSL modem that supports high-bit-rate data transmission.
  • Line modules for the transmission of voice data in the voice network.
  • line modules also have a Interface (such as in the frame relay, Ethernet or ATM transmission system) for packet-oriented data transmission over a data transmission network with high data transmission rates (eg the Internet).
  • Interface such as in the frame relay, Ethernet or ATM transmission system
  • Data transmission in the xDSL data transmission method is defined, for example, in the standards G.992.2 and G.Lite of the ITU (International Telecommunication Union). These standards provide that when the connection to the high-bit data transmission is cleared, a so-called "dying gas" message is sent from the subscriber's xDSL modem to the line module in the switching center (also central office, CO), which ensures an orderly breakdown of the physical Shows connection. If the connection is broken uncontrolled, e.g. in the event of a power failure or the xDSL modem being switched off, however, the "Dying Gasp" message remains off.
  • the manufacturers of the xDSL modes also NIC, Network Interface Card
  • their own power supply e.g. a very large capacitor, accumulator or a battery, so that the "Dying Gasp" message can still be sent after the power supply to the PC fails.
  • the object of the present invention is therefore to provide a data transmission device (xDSL modem, NIC) according to the preamble of appended claim 1 and a method for clearing a connection for high-bit data transmission according to the preamble of appended claim 5, in which the effort for Sending the "Dying Gasp" message for the orderly termination of the connection for high bit rate data transmission (xDSL data transmission) is significantly reduced.
  • xDSL modem NIC
  • the operating system of the personal computer is monitored and, upon detection of one or more states which are highly likely to result in an interruption of the connection to the high-bit data transmission or a switching off of the power supply, a "dying gasp" by the data transmission device according to the invention.
  • Message ie a standardized message to clear the physical connection, sent to the exchange.
  • the advantage of the present invention is that no additional components such as e.g. a large capacitor, accumulator or a battery, and no separate monitoring of the power supply of the data transmission device has to be provided in order to send a correct “dying gasp” message, which reduces the manufacturing costs and the space requirement of the data transmission device (xDSL modem) has the consequence.
  • the present invention takes advantage of the fact that in many cases it can be recognized whether the personal computer (PC) is switched off and thus the power supply to the data transmission device according to the invention is interrupted.
  • the detection device can monitor the operating system or drivers of the operating system and, in the event of an error (instability, "crash"), send a "dying gasp" message to the switching center.
  • the present invention thus offers a simple and inexpensive method of reliably sending the "Dying Gasp" message to the switching center.

  • Fig. 2 shows the schematic structure of the data transmission device according to the invention.
  • the switching center (Central Office, CO) 2 contains, among other things, the line modules 3a ... 3n for connecting the subscribers or their terminals 1 (customer premises equipment, CPE) to the switching center 2.
  • These line modules 3a ... 3n provide subscriber 1 with both conventional telephone services (analog or digital) and high-bit-rate data services using the xDSL transmission method (eg ADSL, UDSL).
  • Various devices such as a telephone 4 and a computer with an xDSL modem 5, are available to subscriber 1 to use the services offered.
  • the services offered are divided at subscriber 1 by a splitter 6 onto the respective end devices.
  • the splitter 6 is provided, for example, in the recommendation G.dmt. In the G.lite recommendation, for example, there is no such splitter; There, separate filters (high pass, low pass) are provided for the distribution of the services for the respective end devices (telephone, PC) (so-called distributed splitter).
  • the services offered are divided by line modules 3a ... 3n over the respective transmission networks.
  • So speech data e.g. transmitted in the PCM process over the voice network and the high bit rate data transmission takes place via its own interface, which e.g. is connected to the Internet (data network).

Abstract

La présente invention concerne un dispositif de transmission de données (7) destiné à la transmission de données à débit binaire élevé entre un ordinateur personnel (5) et un centre de commutation (2). Ce dispositif comprend un dispositif de détection (8) permettant de surveiller le système d'exploitation de l'ordinateur personnel. Lorsqu'un certain état du système d'exploitation est détecté, un message standard de coupure de la liaison physique est envoyé au centre de commutation (2). L'invention concerne également un procédé de coupure d'une liaison physique destinée à la transmission de données à débit binaire élevé.
