摘要

The invention relates to an arrangement for implementing voice transmission using a subscriber line of a public switched telephone network in a system having a concentrator network part connected to the subscriber line for connecting a plurality of subscriber lines to a data transmission network. The concentrator network part comprises voice traffic processing means, which are arranged to perform a conversion between analog voice signals of the subscriber lines and IP voice packets. It further comprises transceiver and multiplexing means for transmitting and receiving data transferred over analog subscriber lines, and packet traffic switching means, which are arranged to receive and transmit packets between the voice traffic processing means and a core network and between the transceiver and multiplexing means and a core network.
