SRX110 Services Gateway Integrated VDSL2 Interface Overview

Very-high-bit-rate digital subscriber line (VDSL) technology is part of the xDSL family of modem technologies. It provides fast data transmission over a single flat untwisted or twisted pair of copper wires.

VDSL lines connect service provider networks and customer sites to provide high-bandwidth applications (Triple Play services) such as high-speed Internet access, telephone services such as voice over IP (VoIP), high-definition TV (HDTV), and interactive gaming services over a single connection. VDSL2 is an enhancement to VDSL and permits the transmission of asymmetric (half-duplex).

VDSL2 uses:

The services gateway supports integrated VDSL2. The integrated VDSL2 carries the Ethernet backplane. On the SRX Series Services Gateway, integrated VDSL2 provides ADSL backward compatibility.

Integrated VDSL2 is compatible with the ITU-T G.993.2 (VDSL2) standard.
