H A P T E R This chapter introduces the VDSL2 line card's general features, default settings and hardware. 1.1 VLC Overview The VLC VDSL2 Line Card is perfect for ISPs or large building applications seeking to provide high bandwidth broadband services to subscribers while minimizing costs. One VLC provides VDSL2 service for 24 subscribers over existing telephone wiring, thus avoiding the cost and hassle of installing new wiring.

Chapter 1 VLC Overview VDSL2 Compliance • ITU-T -G.993.2 -G.994.1 Discrete Multi-Tone (DMT) Modulation The VLC is a DMT-based VDSL2 solution which dynamically adapts the bit transfer rate to conditions on the local loop. This allows the line card to sustain high performance even over noisy lines.
VDSL2 to ADSL2+ Fallback The VLC can automatically use ADSL2+ for connections where VDSL2 training fails. This allows a longer connection distance. Spectral Mask PSD (Power Spectral Density) defines the distribution of a VDSL line’s power in the frequency domain. A PSD mask is a template that specifies the maximum allowable PSD for a line.

Chapter 1 VLC Overview Alarm LED An ALM (alarm) LED lights when the VLC is overheated or the voltage readings are outside the tolerance levels and turns off when the temperature or voltage has returned to a normal level. The IEEE 802.1ag Connectivity Fault Management (CFM) specification allows network administrators to identify and manage connection faults.

IGMP Snooping The VLC supports IGMP snooping enabling group multicast traffic to be only forwarded to ports that are members of that group; thus allowing you to significantly reduce multicast traffic passing through your VLC. IGMP Filter The IGMP filter defines multicast groups a port can join. You can create IGMP filter profiles which allow access to a multicast group, then assign the IGMP filter to a specific VDSL2 port.
Chapter 1 VLC Overview DHCP Relay DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132) allows individual computers to obtain TCP/IP configuration at start-up from a server. You can configure the system as a DHCP relay agent to have another DHCP server provide TCP/IP configuration for the clients.

Chapter 3 VLC Troubleshooting 3.3 VDSL2 Data Transmission The VDSL2 link is up, but data cannot be transmitted. Table 11 VDSL2 Data Transmission Troubleshooting STEPS CORRECTIVE ACTION Check the line card’s port isolation settings. If the subscriber is having problems with video or other high-bandwidth services, make sure the line card’s VDSL2 port’s data rates are set high enough.
3.6 The Line Card is Not Manageable The line card always uses the default configuration. Any changes you did to the line card are stored on the MSC. By default, the MSC is allowed to manage every line card. Use the command on the MSC to see a line card’s connection status.
