Definitions

  • the object on which the invention is based is to enter a further method and a further arrangement for coupling messages from a central control device to a decentralized communication device which
  • a further development of the described method is particularly advantageous for coupling several decentralized devices to a central control system, because decentralized messages are coordinated and distributed and only have to be transmitted bundled on one line to the central office.
  • Groups for which messages are collected and distributed can advantageously be set up for the administration of a number of decentralized facilities, because in this way, message collection and distribution facilities that can already be used for central facilities of a known type can be used in decentralized facilities.
  • the messages are sorted before they are processed, because this enables a clear group-specific prioritization and processing of the messages.
  • At least two types of connecting lines are particularly advantageously used, on which different transmission protocols are implemented.
  • HDLC-based protocols are advantageously used for the exchange of messages at close range, because in this way already > co l ⁇ > P 1 ⁇ - cn o cn o Cn o Cn
  • control messages for connection control of a switching matrix are generated and transmitted to the second decentralized communication devices, or used to control the switching matrix in mixed arrangements, in a further development of the arrangement described. In this way, connections can be established in the entire area of the switching device, regardless of whether the communication participants are connected to new types of devices or to conventional devices.

  • Figure 5 illustrates an advantageous embodiment of an arrangement for message coupling based on an ATM network
  • Figure 6 shows a detailed view for coupling decentralized devices to a central control device an ATM network.
  • Such private branch exchanges are also not modularly expandable because the switching matrix MTS can only be provided as a whole, for example. This means that, in extreme cases, a new switching matrix with, for example, 4096 connections must be purchased and installed for a single additional connection. In such systems, the transmission rate is limited, for example, by the possibility that only a maximum of 64 kbit or another administratively defined or technically determined amount of data can be transmitted per time slot, which is specified by the ISDN standard. Different data rates for individual communication connections are not possible.
  • FIG. 2 shows an example of an arrangement for setting up, clearing down and operating communication connections via decentralized devices which are controlled by a central device.
  • a private branch exchange 250 is shown here, for example.
  • Identical components of the device are identified in FIG. 2 with the same reference numerals as in FIG. 1.
  • Such a construction of a switching system has the advantage that existing networks, in the form of public or private networks, can be used for the transport network.
  • only the control network has to be routed to the central facility ZE2.

  • the first communication connections 2012 to 2237 to the respective first decentralized devices are generally connections via which time-critical control messages are transmitted.
  • the HDLC method between the first decentralized device and the second decentralized device is used as the first communication protocol.
  • These first communication connections can advantageously be made in the form of a backplane bus of a second decentralized device.
  • This variant of the embodiment makes it possible to use, as the first decentralized devices, assemblies which are used in conventional systems 150 for the connection of communication terminals.

  • Peripheral devices previously used are still connected to ZE2 via a device (not shown) DCL.
  • An additional software module decides whether messages are sent as before via DCL or via the IP route and thus via the Ethernet connection. In the opposite direction, this software also maps both inputs (DCL and IP) onto one.
  • the additional software module thus provides a uniform interface in the direction of system software and hides the split into two different transmission paths and types.

  • a protocol conversion of the Internet protocol takes place via the ATM network according to the Internet protocol on the Ethernet. This is done in ZIP or m ZETH. Information between these components is exchanged via an internal Z100 connection line.
  • the Ethernet connection module is connected to the second central unit ZZE2 via the second communication link 2020 to an ethernet access module ETH.

  • Such an arrangement decouples the ATM access from the central control device ZE2.
  • a second central unit ZZE2 can be constructed essentially in the same way as a device ZE2, which was described in FIG. 2. It is therefore not necessary to make complex changes in an existing system in order to enable it to communicate on an ATM network in accordance with the Internet protocol.
  • This property is provided by the first central unit EZE2. While in known devices the polling of the first decentralized device DZ15 and DZ12 from the second central len unit ZZE2 was carried out, this is now done from a proxy module HDLCl in the second decentralized facility DZl.
