The TDM-C400 is ADSL/ADSL2+ customer premise equipment that provides high-speed asymmetrical data transmission on a single twisted copper pair. The DSL line interface supports various ADSL standards, up to ADSL2+. At the DTE side these CPEs provide, dual interfaces, a 10/100 Ethernet interface and one USB port for easy connection to users PC or LAN environment. TDM-C400 delivers broadband access for enterprises, telecommuters, home, and remote office workers with high-speed data transfer requirements.
