The improvements of Digital Subscriber Line (DSL) technology enable telephone companies to optimize the utilization of their twisted-pair access networks in a flexible way, closely relating bandwidth demand and system costs. However, for the definition of VDSL systems as the next generation of DSL spectral compatibility with other DSL systems and with amateur radio systems has to be considered....

This paper describes the results of a project in which the standard Amateur Packet Radio network link layer protocol, AX.25 (a modified version of X.25), was added to the Ultrix kernel. By implementing AX.25 under Ultrix, and by taking advantage of the IP implementations that already exist for PCs, it is possible for packet radio users with PCs to access IP-based services running on our server ...

But there are currently no standardized protocols in use, and there is no widespread use of news forwarding protocols at all among amateur TCP/IP stations. This paper discusses how the Network News Transfer Protocol can be used to distribute news between stations on packet radio networks. NNTP is a standardiz...
