Prestige 861H-G1 Atm-based Vdsl Modem

Product Description:
VDSL, the fastest offering of DSL, provides significantly higher bandwidth than other DSL technologies. VDSL technology, which is similar to that of ADSL, uses existing copper wires to deliver high-speed data services.The major issues with VDSL technology are the line codes to be employed, which can be divided into either single-carrier or multi-carrier modulation schemes. For example, QAM is the most widely used form of single carrier systems while DMT, the standard line code for ADSL, is the primary form of multi-carrier modulation. Both QAM- and DMT-based systems can be designed for VDSL applications. However, DMT modulation dynamically adapts the bit rate to conditions on the local loop and offers excellent performance even over noisy lines.ZyXEL's Prestige 861H series, DMT-based VDSL modem supports a complete range of speeds ranging from 64Kbps to 25Mbps. Symmetric speeds for the Prestige 861H series range up to 25Mbps at 64Kbps increments while asymmetric speeds range up to 52Mbps downstream and 26Mbps upstream at 64Kbps increments. The built-in 4-port switch allows multiple devices to share the bandwidth without the cost of additional network hardware.
