Abstract
Line termination units having dual ports for accepting communication traffic of two different types facilitate the concurrent transmission of voice traffic, serial data traffic and packetized data traffic across a telecommunication transport system, such as a DSL (digital subscriber line) system. The bandwidth of the telecommunication transport system is allocated between the differing traffic types to permit the full utilization of the available bandwidth.
