Definitions
- the invention relates to a method in which digital user data are first transmitted in a first data transmission network to a first network transition unit.
- the user data transmitted in the first data transmission network are coded in accordance with a first type of coding.
- the network transition unit forwards the user data into a circuit-switched network, in which the user data are transmitted in time channels.
- the digital user data are, for example, voice data, video data or program data.
- the first data transmission network is, for example, a data network in which data packets are forwarded.
- a data packet usually contains an address part and a user data part. For example, a destination address and a sender address are specified in the address section.
- the data packets are forwarded based on the destination address.
- a typical protocol for forwarding data is the internet protocol.
- ATM networks Asynchronous Transfer Mode
- the data packets are referred to as cells in which so-called path and channel information is stored for forwarding.
- the first type of coding is, for example, a coding according to standard G.723.1 "Dual Rate Speach Coder Multimedia Communications Transmitting at 5.3 and 6.3 Kilobits per Second" of the ITU-T (International Telecommunication Union - Telecommunications Standardization Sector).
- G.723.1 Dual Rate Speach Coder Multimedia Communications Transmitting at 5.3 and 6.3 Kilobits per Second
- another type of coding can also be used in the first data transmission network, e.g. a coding according to G.726.
- connection establishment phase at the lower protocol levels, in which resource cen of the network, namely transmission channels, are occupied for the connection.
- Different transmission channels are interconnected in such a way that a connection is established between two participants.
- the digital data are then forwarded in transmission channels.
- a synchronous data transmission is carried out in which a predetermined number of digital data are transmitted in a fixed time frame, for example every 125 ⁇ s.
- the connection clearing phase the occupied resources are released again, whereby the transmission channels are separated from each other again.
- Network gateway units are known, for example, from the ITU-T standard H.323 (02/98) "Packed Based Multimedia Communications Systems".
- the gateway is also referred to as a gateway in this standard.
- the gateway unit completes the signaling on each side, i.e. for two fixed protocols. On the packet network side, signaling is carried out, for example, in accordance with protocol H.323.
- the circuit-switched network which are defined for the ISUP protocol (ISDN User Part) in standard Q.765 section 3.5.4.
- the coding type is coded in a parameter called "Transmission Medium Requirement”.
- the coding type language which encodes a coding according to standard G.711, and the coding type "64 kilobits per second unlimited”.
- Associated units and an associated program should also be specified.
- the invention is based on the consideration that switching centers used in the circuit-switched network expect signaling in accordance with a standardized signaling protocol in which only certain types of coding are permitted. Deviations from the protocol lead to errors and are therefore not possible. On the other hand, the transmission of the user data can only be carried out with a high quality if the first type of coding is also used for the transmission of the user data in the circuit-switched data transmission network.
- the first network transition unit signals a second coding type for the useful data, which deviates from the first coding type, in accordance with a signaling protocol specified for the switched-through data transmission network.
- the first gateway unit also signals the first type of coding to the circuit-switched data transmission network.
- the user data in the circuit-switched transmission network are encoded according to the first coding type to form a second network gateway.

- the first data transmission network and / or the third data transmission network are packet transmission networks in which the user data are transmitted in data packets which are forwarded as a function of target information contained in the data packet.
- the first data transmission network or the third data transmission network is a network operating in accordance with the Internet protocol or an ATM network (Asynchronous Transfer Mode).
- the first network transition unit forwards useful data with different target information and / or for different applications into a common transmission channel of the circuit-switched network.
- This measure allows the transmission channels of the circuit-switched network to be filled up to their specified transmission capacity.
- the switched-through network has no knowledge of the type of user data. For example, transmission channels between two company locations or between network operators can be used well.
- the invention also relates to a gateway unit which is used as a first gateway unit and / or as a second gateway unit.
- the network gateway unit is constructed such that it carries out the method according to the invention or one of its further developments during its operation.
- the technical effects mentioned above also apply to the network gateway unit.
- the invention relates to a control unit for a network transition unit which, in the method according to the invention or one of its developments, is the first network transition unit. unit or as a second gateway unit.
- the technical effects mentioned above also apply here.
- the invention also relates to a program with an instruction sequence, when executed by a processor the method according to the invention or one of its further developments is carried out or when executed the functions of a unit according to the invention or a further development of such a unit are performed.
- the technical effects mentioned above are also transferred to the program.

- the data transmission connection 10 serves for the transmission of voice data.
- the voice data are encoded according to the ITU-T standard G.723.1. co co MM 1 P 1 cn o Cn O Cn O Cn
- a PCM-30 link (pulse code modulation) 34 which transmits thirty user channels, is used to transmit the user data from the network transition unit 22 to the switching center 30.
