Definitions

• the invention relates to a method and Anord ⁇ planning for assembly and disassembly of communication links, particularly in the context of a private branch exchange and the connected Endgerate.
• switching devices are subject to ever increasing demands with regard to the amount of data to be transmitted per communication connection and the number of each other connectable communication terminals.
• Current facilities are based, for example, on the TDM method (Time Division Multiplexmg) in which communication data of different connections are transmitted with defined time slots.
• a connection of different communication partners is established by a switching matrix, which assigns incoming time slots on an incoming connection to an outgoing connection according to control information.
• switching networks are m the

• this facility for providing performance features can also provide further applications and / or an interface to applications that go beyond communication performance features.
• advantageously external server for example, call center solutions, CTI (Compu ⁇ ter Telephony Integration), via standardized interfaces centrally coupled.
• a private branch exchange according to a further development of the arrangement described can be set up particularly advantageously, which combines at least two decentralized switching devices with a central control device, because in this way a distributed branch exchange system in the form of a minimum configuration is made available, which can be expanded in any manner.
• a development of the described minimum configuration particularly advantageously has a device for providing connection-related and other performance features, because in this way the decentralized provision and implementation of the performance features in the transport network can be dispensed with for this private branch exchange.
• an emergency control device which enables emergency operation between communication terminals which are connected to this decentralized device if the central control device fails or the control network is interrupted. This ensures a very high level of availability with a single system that corresponds to the availability of networked systems.
• FIG. 1 shows a conventional communication arrangement
• FIG. 2 shows an example of a new communication arrangement
• FIG. 3 shows an example of a message sequence in a known switching system.
• FIG. 4 shows an example of a message sequence using time slot-related connection information for the transport network.
• FIG. 1 shows an example of a known private branch exchange 150 with two peripheral devices P1 and P2, to each of which a digital or analog communication transmitter KE1 and KE2 is connected.
• peripheral devices P1 and P2 are housed in the same spatial area as the central device ZE1. For example, they are in the same room or in the same cabinet with her.
• the end devices occupy defined time slots of a PCM data stream (Pulse Code Modulation) with communication data.
• the digital or analog communication transmitters KE1 and KE2 are each connected to connection modules SLMOl and SLM02, which digital data to the PCM data stream, which are intended for the respective terminal devices or originate from the respective terminal devices, via time slots defined by signaling feed or remove.
• These PCM data streams are designated 100 and 200 in FIG. 1.
• Signaling connections are also shown, which are shown at 110 and 210, respectively. It should be noted that this is only a logical representation and not a physical representation. In reality, however, the transport data and the signaling data are transmitted
• pe ⁇ phere devices P1 and P2 as well as supply modules LTUC1 and LTUC2 are shown, which regulate the data traffic to the connection modules of the respective decentralized devices.
• DZ2 to the central facility ZE2 are paid via public lines, for example dedicated lines, as would have been the case previously with a remote peripheral facility 150 from FIG. 1 in the case of communication from DZ1 to DZ2.
• a transport network-dependent call process is preferably carried out on the decentralized switching devices CS1 and CS2, but is essentially restricted to basic call functionality.
• Features are realized and provided by the central control ZE2. Connections between the different decentralized devices are controlled by the central device ZE2 via signaling.
• the advantages of this arrangement are that it is both narrowband and broadband capable.
• the transport network can be set up both on public and private networks, or on a mixture of the two.
