Automated Functional xDSL CPE Testing

DSL (Digital Subscriber Line) technology is still frequently used in many parts of the world, despite the rise of newer internet technologies like cable internet and fiber-based networks. DSL allows for the transmission of digital data over copper phone lines and is still an ideal solution in areas where other types of networks are not available or do not offer consistent, high-quality connections. DSL is also attractive mainly because it uses installed infrastructure.

DSL Automated Functional Testing

Leveraging technology over copper lines is a cost-effective solution for operators today. With the cost of running Fiber-to-the-Home still high enough to encourage copper-based solutions, xDSL offers a viable alternative. Copper represents a valuable installed infrastructure, and Fiber can be considered too expensive to simply replace all of the installed copper lines. With this in mind, DSL-based technology may be around for many years in some form. Traditional ADSL2 and VDSL2 have offered distance-relative speeds, with VDSL2 offering 100 Mbit/s at 500m (1640.42ft) and 50 Mbit/s at 1000m (3280.84ft). ADSL2 and other previous technologies offer even lower performance, with performance degrading the further from the source of the signal the xDSL modem is installed. Other DSL technologies like G.fast offer a higher-speed (up to 1 Gbit/s) alternative to pure fiber and cable, and can be used in a hybrid network where fiber is brought to the curb (or an MDU) and the internal copper wiring then delivers the G.fast service to the customer or customers. XG-FAST has promised speeds up to 8X over 100 meters.

xDSL technology utilizes a DSLAM (digital subscriber line access multiplexer) which acts as a controller connecting multiple DSL-based devices to a high-speed digital internet connection. Depending on the technology used, as listed above, a particular type of DSLAM will be used for different device support. An ADSL2 modem needs a compatible DSLAM, and the same holds true for G.fast, VDSL2 or other similar technologies. Some of these technologies can coexist in the same DSLAM. Much as a fiber network uses an OLT (Optical Line Terminal) and a DOCSIS cable network uses a CMTS (Cable Modem Termination System), a DSL network needs a DSLAM to operate properly
