Home / xDSL


Today, tripleplay (3P) services (voice, video, data) can be provided simultaneously to the customer over the telephone-line via ADSL2 and ADSL2+ technology. The transport of different services, i.e. different traffic classes, over the same shared media in the access network constitutes a wide range of distinct Quality of Service (QoS) and Class of Service (CoS) requirements which have to be met by an IP-based network on the physical layer (L1), link layer (L2), and network layer (L3).

The introduction of new services is also involving new security threats and risks. Thus within this project also the security area should be addressed.
