DSL VS CABLE The market for interactive home video services via x.DSL and Cable offer consumers a variety of opportunities over a high-speed connection. Each service, with its own advantages, share one important factor that consumers value most; high quality service at relatively low costs. Although, currently both technologies are in competition with each other, eventually one will prevail creating a standard for interactive home video.

The first service to be analyzed is x.DSL or Digital Subscriber Line. DSL is a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines. xDSL refers to different variations of DSL, such as ADSL, HDSL, and RADSL. Assuming your home is

At the other end of each transmission, a DSLAM demultiplexes the signals and forwards them to the appropriate individual DSL connections.

x.DSL presents numerous opportunities to the home consumer. Features such as high speed Internet access, software on demand (SOD), videoconferencing, streaming video and voice signals, are all very attractive to the common dial-up customer. One example where SOD is a key feature, is a CD-ROM Shim developed on the Mpowered platform (by MTT). This is a customer designed software layer that lets end users who do not have CD-ROM equipped computers run CD-ROM dependent applications. The SOD platform will also offer users access to real-time billing information. What’s even more attractive is the fact that DSL presents a nailed circuit in which one is continuously connected. Also unlike cable, DSL works over existing phone lines and because each user has their own dedicated circuit, there is no competing for bandwidth with neighbors in your area.

The most widely used form of X.DSL is ADSL (Asymmetric Digital Subscriber Line). ADSL is called "asymmetric" because most of its duplex bandwidth is devoted to the downstream direction, sending data to the user. Only a small portion of bandwidth is available for upstream or user-interaction messages. However, most Internet and especially graphics- or multi-media intensive Web data need lots of
