Abstract
A method and apparatus for improving the transmission quality in a packet-oriented data transmission network, wherein time-critical data is transmitted over a packet-oriented data transmission network having a number of communications equipment units which are networked to one another.
Claims11
A method for transmitting time-critical data over a packet-oriented data transmission network, the method comprising the steps of:
- providing, as part of the network, a plurality of communications devices connected to one another;
- connecting a plurality of terminals to the communications devices;
- selecting an echo compensator as a function of a type of link between the terminals;
- transmitting sampled values of the time-critical data to be transferred over the data transmission network in data packets;
- reducing a packet transmission rate of the data packets to be transferred when the data transmission network is overloaded;
- reconstructing, in a receiver device, received time-critical data, in the event of a loss of data packets;
- and
- compressing and decompressing signaling data and time-critical data using bit-error-tolerant Codec methods for voice data transmission.

A communications equipment unit for connecting a plurality of terminals to a communications network, the communications equipment unit comprising:
- an interface to a packet-oriented data transmission network, wherein sampled values of time-critical data to be transferred are transmitted over the data transmission network in data packets;
- a selection device for selecting an echo compensator as a function of a link between the terminals;
- a reduction device for reducing a packet transmission rate of the data packets to be transferred, when the data transmission network is overloaded;
- a reconstruction device for reconstructing, in the event of a loss of data packets, time-critical data to be received;
- a signaling compression device and a signaling decompression device for respectively compressing and decompressing signaling data;
- and
- a data compression device and a data decompression device for respectively compressing and decompressing the time-critical data via bit-error-tolerant Codec methods for voice data transmission.
