• Robust operation on severely distorted lines
• Supports power back-off algorithm that permits a mixed distance
deployment
Additional VDSL2 features include:
• Fast startup for quick initialization
• Trellis coding modulation for higher performance
• Seamless rate adaptation for enhanced quality in video applications
• Variable tone spacing enables best performance for long and short
reach lines
• Improved framing, overhead channel, and interleaving
Ethernet Connectivity
• 16 VDSL lines for Ethernet connections to subscribers, operating at
100 Mbps symmetric or at asymmetric rates (such as 100/50 Mbps).
• 2 1000BASE-T/SFP ports provide 4 Gbps of aggregate bandwidth for
network uplink.
• Auto-negotiation enables each RJ-45 uplink port to automatically
select the optimum speed and communication mode (10/100 Mbps at
half/full duplex, or 1000 Mbps at full duplex) if this feature is supported
by the attached device; otherwise the port can be configured manually.
• RJ-45 ports support auto MDI/MDI-X pinout selection.
• Unshielded (UTP) cable supported on all RJ-45 ports: Category 3 or
better for 10 Mbps connections, Category 5 or better for 100 Mbps
connections, and Category 5, 5e, 6 or better for 1000 Mbps
connections.
• IEEE 802.3-2005 Ethernet, Fast Ethernet, Gigabit Ethernet
compliance ensures compatibility with standards-based hubs, network
cards and switches from any vendor.
