A method and a device for data communication between a first instance and a network are provided, wherein the first instance is connected via a first interface with the network. In the novel method, the first instance is connected with the network via at least one second interface.

The invention relates to a method for storing and passing on multimedia messages for a multimedia call in a packet-switching telecommunication network (TN), with the called subscriber (B subscriber) having network access with a known and predetermined bandwidth to the telecommunication network (TN). In the situation where it is found () during the setting up of a multimedia call that the available bandwidth is too narrow () because the called subscriber (B subscriber) is currently using a further multimedia service, the multimedia call is diverted () to a recording device (ABZ) which is available in the telecommunication network (TN). A calling subscriber (A subscriber) can then leave a multimedia message on the recording device (ABZ), which is then passed () to a local recording device (ABL) for the called subscriber (B subscriber) via the network access and using the bandwidth that is still available. The arrival of the new multimedia message is then indicated () to the called subscriber (B subscriber) after complete transmission. The method according to the invention results in the subscriber (B subscriber) in a packet-switching telecommunication network (TN) being informed () that a multimedia call has arrived, with the recording device (ABZ) that is available in the telecommunication network (TN) advantageously carrying out a form of buffer function. This buffer function makes it possible to use time expansion to make use of the bandwidth that is still available for transmission of the multimedia message ().

DSL methods, e.g. ADSL/SDSL, are increasingly used for quick access to the Internet. A data terminal of the subscriber is connected via a conventional copper twin wire to an access multiplexer by means of a modem. The access multiplexer is placed in an access node of the network provider, which provides the connection for the subscriber. Typically, the digital subscriber lines of a number of subscribers are connected via corresponding interface modules of the access multiplexer. The linking of the access multiplexer to downstream network elements is effected by means of an Ethernet network that is cost-effective with regard to both design and operation.
