The provision of subscriber service features is one of the tasks of exchanges in classic TDM networks. This includes e.g., announcements and interactive responses. According to the prior art, these announcements and interactive responses are either provided by peripheral devices of the exchange which are equipped with the appropriate function or by external announcement and interactive response systems. The latter are provided either in TDM networks with proprietary interfaces or in packet networks with standardized interfaces. The invention solves the problem of providing the service for classic TDM networks by providing that the known packet-based method for controlling an external system for providing announcements and interactive responses is transferred to an exchange located in the classical TDM network. In particular, this enables the protocol used to control the external announcement and interactive response system, which was originally standardized as a signalling protocol for controlling a media gateway, to be used.

Method for controlling announcements and interactive responses in an exchange

The invention relates to a method for controlling recorded announcements and interactive voice responses for calls made outside an exchange, using a packet network (PN), by means of peripheral equipment (LTG) of a switching system, which does not provide any HW-oriented tasks for its interface system controlled by switching technology, whereby peripheral equipment (LTG) with virtual ports is defined. The method is characterised in that resources for the recorded announcement and interactive voice response function are provided by an external device, that the peripheral equipment is provided with virtual recorded announcement and interactive voice response ports, that an interface exists between the peripheral equipment and the external device and that the external resources can be used in relation to a specific port by the switching system.

Method for controlling recorded announcement and interactive voice responses in packet networks

The invention relates to a method for providing voice channel-related functions in a telecommunications network, whereby first voice channel functions are centrally provided, and second voice channel functions are decentrally provided. The invention also relates to a telecommunications network for implementing this method.

Splitting up the handling of-voice channel-related functions in a telecommunications network, whereby only the least used functions are centrally provided

The invention relates to an exchange for a telecommunication network, with a message/dialogue device, whereby said message/dialogue device, comprises one interface each for a packet-oriented data transmission network and a line-oriented data transmission network and a virtual port for controlling the message/dialogue device, by means of a connection running through the packet-oriented data transmission network, for the transmission of messages and/or dialogues to a user.

Arrangement for the provision of messages and dialogues in packet networks

Telephone calls are handled via the Internet between an interworking unit relating to the calling subscriber and an interworking unit relating to the called subscriber. At least the telecommunications network to which the calling subscriber belongs as well as the interworking units are operated by the same provider. Access by a calling subscriber to the interworking unit and the passing on of the dialed telephone number of the called subscriber to the interworking unit are made dependent on the identification of the call as an Internet telephone call and dependent on the result of an access authorization check. Charging for use of the telephone network and of the Internet for such a call does not commence until the connection is made, as in the case of a call which uses only the telephone network.

Method for handling telephone calls via at least one telephone network using the internet

Method for handling information contained in a header portion of message

The telecommunication network is composed to a greater degree of ATM exchanges (ATM) and to a lesser degree of STM exchanges (STM). Information coming from an STM exchange (for example, STM1) ad to be switched to a further STM exchange (for example, STMy) via an ATM exchange (for example, ATM1) are packeted in short cells for through-connection through the ATM exchange (ATM1) in order to reduce the packeting time. These short cells have a shorter length when compared to the standardized message cells used for information transmission between ATM exchanges.

Telecommunication network having ATM switching centers and STM switching

The telecommunication network is composed to a greater degree of ATM exchanges (ATM) and to a lesser degree of STM exchanges (STM). Information coming from an STM exchange (for example, STM1) and to be communicated to a further STM exchange (for example, STMy) via an ATM exchange (for example, ATM1) is packeted in message cells of the same length as those message cells used for the transmission between ATM exchanges in order to reduce the packeting time for the through-connection across the ATM exchange (ATM1). However, respective message parts of a plurality of STM time channels (K1 through K4) that are to be through-connected to the same ATM exchange output are multiplexed in a message cell.

Telecommunication network

The telecommunication network is composed to a greater extent of ATM exchanges and to a lesser extent of STM exchanges. For reducing the packeting time for the through-connection across the ATM exchange, information coming from an STM exchange and to be switched via an ATM exchange to a further STM exchange is packeted either into message cells that are shorter in comparison to standardized message cells used for the transmission between ATM exchanges or into message cells of the same length wherein, however, respective message parts of a plurality of STM channels that are to be through-connected to the same ATM output are multiplexed in a message cell. Given local exchanges (ATM-V) having decentralized line units (SLUR) for the connection of subscriber lines, the message cells of a plurality of STM channels are packeted multiplexed thereat without taking the exchange destination into consideration. A conversion into one of the aforementioned message cells that deviate from the standard cells then occurs in the exchange.

A switching configuration for PCM TDM telecommunication exchange insallations, having a central switching network and individual sub-switching networks is provided. Line groups having duplicated central switching networks connected over two time division multiplex lines and having a sub-switching network and a group control system each are assigned to each other in pairs. The line systems assigned individually to the one and the other of two line groups and which are connected via internal lines in normal operation to the sub-switching networks of their own line group, can be switched over to the sub-switching network of the other line group. No connections are interrupted which were already through-connected before changeover switching or were in the process of being set up, and the internal lines running form the line system of one line group can be switched over singly, i.e. individually to the connection, from its sub-switching network to that of the partner line group. Unseized internal lines are switched over, or also connections in the call phase are through-connected. For new connections, only already switched-over internal lines are available.
