Key Features
VDSL features (CPE side) include:
• High-speed Internet access over existing phone lines
• VDSL connection provides the following rate/range options:
• Concurrent data and telephone services (voice/ISDN) over a single connection
• Always-on digital connection eliminates dial-up delays, and transparent
reconnection when initiating any network request
• Supports evolving ETSI, ANSI and ITU VDSL standards for the copper local loop
• Spectral compatibility with POTS, ISDN (2B1Q/4B3T) or “Smartphone” digital PBX
• Port-to-port isolation for Ethernet
• Robust operation on severely distorted lines
• Supports power back-off algorithm that permits a mixed distance deployment
Ethernet features (CO side) include:
• Optional 1-port 1000BASE-T, 1-port 1000BASE-SX,1-port 1000BASE-X GBIC,
4-Port 100BASE-FX, or 4-Port 10/100BASE-TX modules
• Compliant to IEEE 802.3 10BASE-T Ethernet, IEEE 802.3u 100BASE-TX and
100BASE-FX Fast Ethernet, IEEE 802.3ab Gigabit Ethernet, and IEEE 802.3z
Gigabit Ethernet standards
• The 1000BASE-T port auto-negotiates Ethernet connection at 10/100/1000 Mbps,
full/half duplex at 10/100 Mbps, full duplex at 1000Mbps
• The 1000BASE-SX port cannot be set to auto-negotiation; it is fixed at 1000 Mbps,
full duplex
• The 100BASE-FX ports cannot be set to auto-negotiation; they are fixed at
1000 Mbps, full duplex
• The 10/100BASE-TX ports auto-negotiate Ethernet connection at 10/100 Mbps,
full/half duplex
• Provides back pressure for half duplex and IEEE 802.3x flow control for full duplex
System features include:
• LEDs indicate Ethernet link status/activity, VDSL link status, and System status
• Stacks up to 8 units for console management
• Simple plug-and-play installation
• Switch fabric bandwidth of 9.8 Gbps
• Switching table with a total of 8K entries
• Transparent bridging
