4.16 VDSL Configuration
VDSL2 (Very High-Bit-Rate Digital Subscriber Line 2) , G.993.2 is the newest and most advanced standard of xDSL
broadband wire line communications. Designed to support the wide deployment of Triple Play services such as voice, data,
high definition television (HDTV) and interactive gaming, VDSL2 enable operators and carrier to gradually, flexibly, and cost
efficiently upgrade exiting xDSL-infrastructure.
VDSL2 was developed and standardized in record time to address the shortcomings of existing access technologies. It
servers as the ideal xDSL technology for eliminating last-mile bottlenecks and enable global mass deployment of advance
Triple Play services. Unlike its predecessor, which allowed choosing either DMT (Discrete Multitone) or QAM (Quadrature
Amplitude Modulation) technology, VDSL2 only uses the DMT line code.
DMT is a method of separating a DSL signal so that the usable frequency range is separated into multiple small frequency
bands, or tone. It uses up to 4096 tones which are spaced 4 kHz or 8 kHz apart. Each tone can be used for either
downstream or upstream.
The PLANET VDSL2 Managed Switch can provide very high performance access to remote CPE, both downstream and
upstream up to 100Mbps. The VDSL2 Managed Switch complies with ITU-T G993.2 standard, and supports CO operating
mode. The CO by WEB UI and users can connect to multiple CPE for Point-to-Multi-Point Application, data transmission
between multiple networks over existing copper telephone lines.
