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 MAC (Media Access Control) Filter Use the MAC filter to deny or accept incoming frames based on MAC (Media Access Control) address(es) or OUI (Organizational Unit Identifier) that you specify. You may enable/disable the MAC filter on specific ports. You may specify up to ten MAC addresses per port.
Chapter 1 VLC Overview Static Multicast Use static multicast to allow incoming frames based on multicast MAC address(es) that you specify. This feature can be used in conjunction with IGMP snooping to allow multicast MAC address(es) that are not learned by IGMP snooping. You can use static multicast to pass routing protocols, such as RIP and OSPF.
Chapter 1 VLC Overview DHCP Snooping DHCP snooping allows the system to identify packets with DHCP server assigned IP address(es) and block access of devices using unknown IP addresses on a subscriber port. You can also manually add static IP addresses to the DHCP snooping table. LAN 2 LAN LAN 2 LAN allows you to control whether or not a DHCP server connected to a subscriber port is permitted to receive and send traffic through the IES.
Chapter 1 VLC Overview 1.4 Front Panel of VLC The figure below shows the front panel of the VLC. 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.
Chapter 1 VLC Overview A 24 port POTS splitter is used to differentiate analog signal from the VDSL2 band. The VLC1324G-51 uses the VSC1224-41 and the VLC1324G-53 uses the VSC1224-43U. The splitter is installed in the splitter chassis. See the IES User’s Guide for installation instructions.

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.
