Abstract

See full text

A digital subscriber line (DSL) arrangement provides data and voice over IP (VoIP) services over a subscriber loop. Instead of conventional multiplexing at the IP layer, two separate IP packet streams are provided, one stream carrying delay insensitive data traffic and the other transporting delay sensitive traffic, in particular, packetised voice. The system segments each IP stream (i.e. those carrying voice and data) separately to produce two ATM streams which are then multiplexed using an ATM multiplexer. This reduces the delays to voice traffic resulting from queuing behind long data packets.
