P ART I Introduction, Specifications and Troubleshooting VLC Overview (15) VLC Specifications (23) VLC Troubleshooting (31) 13
CHAPTER 1 VLC Overview 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. Transmit PSD Notches The VLC supports the transmission of PSD (Power Spectral Density) notches at RFI (Radio Frequency Interference) bands. This reduces the effects of strong radio sources nearby.
Chapter 1 VLC Overview 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. The VLC transmitter signal complies with the Power Spectrum Density (PSD) mask specified in ITU-T G.993.
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. CFM The IEEE 802.1ag Connectivity Fault Management (CFM) specification allows network administrators to identify and manage connection faults. Through discovery and verification of the path, CFM can detect, analyze and isolate connectivity faults in bridged LANs.
Chapter 1 VLC Overview 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. In addition, you can set the system to forward client DHCP requests to specific DHCP servers based on the VLAN ID.
Chapter 1 VLC Overview Figure 1 Front Panel 1.5 Ports and LEDs of VLC These are the details of the VLC ports and LEDs. 1.5.1 Ports The following table describes the port labels on the front panel. Table 2 Front Panel Ports LABEL DESCRIPTION CONSOLE For troubleshooting purposes, this mini RJ-11port connects to a computer when the line card is not manageable from the MSC. 1-24 These Telco-50 connectors are for connecting the VLC to the splitter cards. 1.5.

CHAPTER 3 VLC Troubleshooting This chapter covers potential problems and possible remedies. After each problem description, some steps are provided to help you to diagnose and solve the problem. 3.1 The SYS or PWR LED Does Not Turn On Table 9 SYS LED Troubleshooting STEPS CORRECTIVE ACTION 1 Make sure the power wires are properly connected to the power supply and the power supply is operating normally. Make sure you are using the correct power source (refer to the IES User’s Guide for details).
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 1 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. 2 Check the VLAN configuration. 3 Ping the MSC from the computer behind the VDSL2 modem or router.
Chapter 3 VLC Troubleshooting 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 lcman show command on the MSC to see a line card’s connection status.
