Modem Access Adapter prevents mutual interference when telephone and dialup modem share a common phone line. When modem  attempts to dial out adapter searches for an idle line. It disconnects extension phones before connecting modem. This prevents picking up a phone from dumping data connection, or modem from barging into a phone conversation. Adapter hunts over two lines. If both lines are busy modem retries later.

Dialup Modem Impairments Dialup modems are very demanding of the Public Switched Telephone Network (PSTN) and rarely hit advertised speed. This paper describes common  impairments that reduce speed.

Future of Home Networking  A decade  ago computer networks were the province of large companies with well funded IT departments. Internet access was little known outside a small cadre of network professionals. Advances in wired and wireless network technology have made small LANs and Internet access the norm rather then exception. This paper extrapolates from the last ten years to predict how this critical market will evolve over the next decade.

IP vs RF Television High-speed Internet access creates an alternative TV delivery method. Where adequate bandwidth exists IP TV is capable of a much richer suite of services then either CATV or over-the-air. IP TV leverages Internet infrastructure eliminating the need to build a dedicated video distribution network.

Commercial  Peer-to-Peer Distribution  There is much hand ringing by the music and movie industry that Internet peer-to-peer (P2P) file sharing will be the death of artistic expression rather then an opportunity to lower delivery cost. This paper proposes a P2P mechanism for commercial content distribution that compensates artists, provides incentives for customers to play by the rules, while dramatically reducing distribution cost.

Do Third Party ISPs Facilitate Broadband Competition?  One of the more controversial aspect of broadband is the power exercised by first-mile network owners over third party ISPs and regulatory requirements to share these facilities. This paper argues for a different approach. First-Mile networks should provide common carriage -- transparent IP delivery. This allows application developers and ISP's to operate at the network edge independent of physical connection.

Effect of ISP Business Practices on Home Networks  Broadband ISPs are adopting restrictive measures that violate the cherished notion transparent data delivery.  This business strategy has profound effects on home networks. This paper was written to provide background information as part of the Consumer Electronics Association (CEA) Versatile Home Network (VHN) and International Standards Organization (ISO) Residential Gateway (RG) standards activity.

The Rise of Information Gatekeepers The Internet was designed as a transparent end-to-end data delivery network. This cherished concept is threatened by gatekeepers attempting to control how customers use First-Mile access networks.
