(1200 m). the chipset also supports transmission of legacy communication services without disruption. ethernet phy functionality is fully integrated into the octal-10bases chipset for direct connectivity to standard ethernet switching devices. infineon?s vdsl technology uses frequency duplexing and qam modulation to ensure robust operation. its spectral allocation allows noise-free coexistence with other xdsl technologies in the same bundle. the octal-10bases chipset is a very economical solution for distribution of broadband services in mdu/mtu markets and a most suitable solution for broadband lan extension applications.
