CHAPTER 1 Introducing the ALC1248G This chapter introduces the ADSL2/2+ line card's general features, factory default settings and hardware. 1.1 ALC1248G Overview The ALC1248G ADSL2/2+ Line Card is perfect for ISPs or large building applications seeking to provide high bandwidth broadband services to subscribers while minimizing costs. One ALC provides ADSL service for 48 subscribers over existing telephone wiring, thus avoiding the cost and hassle of installing new wiring.
Chapter 1 Introducing the ALC1248G 1.3 Features Here is a partial list of the ALC’s features. ADSL Compliance • Multi-Mode ADSL Standard -DMT T1.413, issue 2 -G.DMT (ITU G.992.1) Annex A -G.DMT (ITU G.992.1) Annex B -G.LITE (ITU G.992.2) • ADSL2 -G.992.3 Annex A -G.992.3 Annex B -G.992.3 Annex L -G.992.3 Annex M • ADSL2+ -G.992.5 Annex A -G.992.5 Annex B -G.992.5 Annex M IEEE 802.1p Priority The system uses IEEE 802.1p priority to assign priority levels to individual PVCs.
Chapter 1 Introducing the ALC1248G Multicast VLAN Multicast VLAN is designed for applications (such as Media-on-Demand (MoD)) using multicast traffic across an Ethernet ring-based service provider network. Multicast VLAN allows one single multicast VLAN to be shared among different subscriber VLANs on the network. This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management. IEEE 802.
Chapter 1 Introducing the ALC1248G Discarding of IGMP Query Messages The ALC discards IGMP query messages received from subscriber ports. This prevents subscribers from hosting IGMP multicast servers. IGMP Statistics The ALC records the number of active users in an IGMP multicast channel (multicast group). The ALC also records IGMP message statistics on a per port basis to ease management and troubleshooting.
Chapter 1 Introducing the ALC1248G System Error Logging The system error log will record error logs locally to the management switch card memory. Remote Firmware Upgrade You can use FTP or SFTP to perform configuration backup/restore and firmware upgrade from a remote location. Anti-IP Address Spoofing With DHCP snooping, the ALC records which IP addresses are assigned on each port. The ALC drops packets from a device using a different IP address.
Chapter 1 Introducing the ALC1248G IP-aware Bridging The line cards can forward frames based on the destination IP address, instead of the destination MAC address, and replace the source MAC address with its own MAC address. This provides better scalability and security for large-scale access networks, especially with Ethernet.
Chapter 1 Introducing the ALC1248G 1.5.2 LEDs The following table describes the LED indicators on the front panel of the ALC. Table 3 LED Descriptions LED COLOR STATUS DESCRIPTION PWR Green On The line card is turned on. Off The line card is off. Blinking The line card is rebooting and performing self-diagnostic tests. On The line card is on and functioning properly. Off The power is off or the line card is malfunctioning. On There is a hardware failure or an alarm.

CHAPTER 3 Troubleshooting This chapter offers some suggestions to solve problems you might encounter. The potential problems are divided into the following categories. • • • • • Power and LEDs DSL Data Transmission Local Server Data Rate Management and Configuration 3.1 Power and LEDs V The SYS or PWR LED does not turn on. Table 9 SYS LED Troubleshooting V STEPS CORRECTIVE ACTION 1 Make sure the power wires are properly connected to the power supply and the power supply is operating normally.
Chapter 3 Troubleshooting The ALM (alarm) LED lights when the line card is overheated or the voltage readings are outside the tolerance levels. Table 10 ALM LED Troubleshooting STEPS CORRECTIVE ACTION 1 Use the sys monitor status command to verify the cause of the alarm. See step 2 if the unit is overheated, and step 3 if the voltages are out of the allowed ranges. 2 Ensure that the IES is installed in a well-ventilated area and that normal operation of the fans is not inhibited.
Chapter 3 Troubleshooting Table 12 Local Server Troubleshooting STEPS CORRECTIVE ACTION 1 Refer to Section 3.2 on page 30 to make sure that the subscriber is able to transmit to the line card. 2 Make sure the computer behind the DSL device has the correct gateway IP address configured. 3 Check the VLAN configuration (refer to the MSC User’s Guide). 4 Check the cable and connections between the line card and the local server. 5 Try to access another local server.
Chapter 3 Troubleshooting " The MSC resets the line card after a period of inactivity on the line card. This may damage the line card if you are uploading the default configuration file or new firmware to the line card. Use the lcman disable command on the MSC to prevent the MSC from managing the line card. After you upload the file successfully, use the lcman enable command on the MSC to allow the MSC to manage the line card again. Refer to the MSC User’s Guide for details about commands.
