ADSL2+line driving solutions

摘要

Digital Subscriber Line (DSL) is a technology that converts current twisted-pair telephone lines into access paths for multimedia and high-speed data communications. A modem is connected to a twisted-pair telephone line, creating three information channels. A high-speed downstream channel, a medium-speed upstream channel and POTS (Plain Old Telephone Service) split off from the modem by filters. These channels depend on the implementation of the architecture as described in Table 1 opposite.
