ADSL4-51Parameter DescriptionStatus Line Status Shows the current status of the ADSL line.Data RateUpstream Maximum data rate upstream.Downstream Maximum data rate downstream.Operation Data/Defect IndicationNoise MarginUpstream Minimum noise margin upstream.Downstream Minimum noise margin downstream.Output Power Maximum fluctuation in the output power.AttenuationUpstream Maximum reduction in the strength of the upstream signal.Downstream Maximum reduction in the strength of the downstream signal. Fast Path FEC Correction There are two latency paths that may be used: fast and interleaved. For either path a forward error correction (FEC) scheme is employed to ensure higher data integrity. For maximum noise immunity, an interleaver may be used to supplement FEC.Interleaved Path FEC Correction An interleaver is basically a buffer used to introduce a delay, allowing for additional error correction techniques to handle noise. Interleaving slows the data flow and may not be optimal for real-time signals such as video transmission.Fast Path CRC Error Indicates the number of Fast Path Cyclic Redundancy Check errors.Interleaved Path CRC Error Indicates the number of Interleaved Path Cyclic Redundancy Check errors.Loss of Signal Defect Momentary signal discontinuities.Loss of Frame Defect Failures due to loss of frames.

A-1CHAPTER ATROUBLESHOOTINGThis section describes common problems you may encounter and possible solutions to them. The Barricade can be easily monitored through panel indicators to identify problems. Troubleshooting ChartSymptom ActionLED IndicatorsPower LED is Off • Check connections between the Barricade, the external power supply, and the wall outlet.• If the power indicator does not turn on when the power cord is plugged in, you may have a problem with the power outlet, power cord, or external power supply. However, if the unit powers off after running for a while, check for loose power connections, power losses, or surges at the power outlet.If you still cannot isolate the problem, then the external power supply may be defective. In this case, contact Technical Support for assistance.
TROUBLESHOOTINGA-2LED IndicatorsLink LED is Off • Verify that the Barricade and attached device are powered on. • Be sure the cable is plugged into both the Barricade and the corresponding device. • Verify that the proper cable type is used and that its length does not exceed the specified limits. • Be sure that the network interface on the attached device is configured for the proper communication speed and duplex mode.• Check the adapter on the attached device and cable connections for possible defects. Replace any defective adapter or cable if necessary. Network Connection ProblemsCannot Ping the Barricade from the attached LAN, or the Barricade cannot Ping any device on the attached LAN• Verify that the IP addresses are properly configured. For most applications, you should use the Barricade’s DHCP function to dynamically assign IP addresses to hosts on the attached LAN. However, if you manually configure IP addresses on the LAN, verify that the same network address (network component of the IP address) and subnet mask are used for both the Barricade and any attached LAN devices.• Be sure the device you want to ping (or from which you are pinging) has been configured for TCP/IP.Troubleshooting ChartSymptom Action

Access points combined with a distribution system (e.g. Ethernet) support the creation of multiple radio cells (BSSs) that enable roaming throughout a facility.Asymmetric Digital Subscriber Line (ADSL)One of four DSL technologies. ADSL is designed to deliver more bandwidth downstream (from the central office to the customer site) than upstream. Downstream rates range from 1.5 to 9 Mbps, whereas upstream bandwidth ranges from 16 to 640 kbps. ADSL transmissions work at distances up to 18,000 feet (5,488 meters) over a single copper twisted pair. Asynchronous Transfer Mode (ATM)A cell-based connection-oriented data service offering high speed (up to 2.488 Gbps) data transfer. ATM integrates circuit and packet switching to handle both constant and burst information. Frequently called cell relay.AuthenticationThe process a station uses to announce its identify to another station. IEEE 802.11 specifies two forms of authentication: open system and shared key.
GLOSSARYGlossary-2BandwidthThe difference between the highest and lowest frequencies available for network signals. Also synonymous with wire speed, the actual speed of the data transmission along the cable.Basic Service Set (BSS)A set of 802.11-compliant stations that operate as a fully-connected wireless network.Cyclic Redundancy Check (CRC)An error detection process that (at the transmitting station) divides the data being sent by a particular polynomial and appends the resulting remainder to the transmitted data. Then (at the receiving station) the process divides the received data by the same polynomial and compares the resulting remainder to the remainder appended to the data at the transmitting station. If the remainders are equal, there is very high probability that no errors are present in the data. If they do not match, then errors are present.Domain Naming System (DNS)System used in the Internet for translating names of network nodes into addresses.Dynamic Host Configuration Protocol (DHCP)Issues IP addresses automatically within a specified range to devices such as PCs when they are first powered on. The device retains the use of the IP address for a specific license period that the system administrator can define. DHCP is available as part of the many operating systems including Microsoft Windows NT Server and UNIX.
GLOSSARYGlossary-3EthernetA network communication system developed and standardized by DEC, Intel, and Xerox, using baseband transmission, CSMA/CD access, logical bus topology, and coaxial cable. The successor IEEE 802.3 standard provides for integration into the OSI model and extends the physical layer and media with repeaters and implementations that operate on fiber, thin coax and twisted-pair cable.File Transfer Protocol (FTP)A TCP/IP protocol for file transfer.FirewallA device that interfaces the network to the outside world and shields the network from unauthorized users. The firewall does this by blocking certain types of traffic. For example, some firewalls permit only electronic mail traffic to enter the network from elsewhere. This helps protect the network against attacks made to other network resources, such as sensitive files, databases, and applications.Forward Error Correction (FEC)A method of error control where the receiving node automatically corrects as many channel errors as it can without referring to the sending node.G.liteA standard that defines the more economical splitterless ADSL connection that transmits data at up to 1.5 Mbps downstream and 512 Kbps upstream. This ADSL option can be installed without an on-site visit by the service provider.IEEEInstitute of Electrical and Electronic Engineers.
GLOSSARYGlossary-4IEEE 802.11Specifies medium access and physical layer specifications for 1 Mbps and 2 Mbps wireless connectivity within a local area.IEEE 802.3xDefines Ethernet frame start/stop requests and timers used for flow control on full-duplex links.International Control Message Protocol (ICMP)Network layer Internet protocol that reports errors and provides other information relevant to IP packet processing. Documented in RFC 792.Local Area Network (LAN) A group of interconnected computer and support devices.LEDLight emitting diode used for monitoring a device or network condition.Logical Link Control Layer (LLC)The highest layer of the IEEE 802 Reference Model and provides similar functions of a traditional data link control protocol. Management Information Base (MIB)Database of network management information that is used and maintained by a network management protocol such as SNMP or ICMP. The value of a MIB object can be changed or retrieved using SNMP or ICMP commands. MIB objects are organized in a tree structure that includes public (standard) and private (proprietary) branches.Media Access Control (MAC)A portion of the networking protocol that governs access to the transmission medium, facilitating the exchange of data between network nodes.
GLOSSARYGlossary-5NodeAny network-addressable device on the network, such as a router or network interface card. Point-to-Point Protocol (PPP)A protocol that provides router-to-router and host-to-network connections over both synchronous and asynchronous circuits. PPP is the successor to SLIP. RJ-45 ConnectorA connector for twisted-pair wiring.Routing Information Protocol (RIP)A common type of routing protocol. RIP bases its routing path on the distance (number of hops) to the destination. RIP maintains optimum routing paths by sending out routing update messages if the network topology changes. For example, if a router finds that a particular link is faulty, it will update its routing table, then send a copy of the modified table to each of its neighbors. Service Set Identifier (SSID)An identifier attached to packets sent over the wireless LAN that functions as a “password” for joining a particular radio network (BSS). All radios and access points within the same BSS must use the same SSID, or their packets will be ignored. Simple Network Monitoring Protocol (SNMP)Defines the transfer of information between Management Information Bases (MIBs). Most high-end network monitoring stations require the implementation of SNMP on each of the components the organization wishes to monitor.
GLOSSARYGlossary-6Transmission Control Protocol (TCP)A commonly used protocol for establishing and maintaining communications between applications on different computers. TCP provides full-duplex, acknowledged, and flow-controlled service to upper-layer protocols and applications. User Data Protocol (UDP)A connectionless protocol that works at the OSI transport layer. UDP transports datagrams but does not acknowledge their receipt. UTPUnshielded twisted-pair cable.Virtual channel Identifier (VCI)A 16-bit field in the header of an ATM cell. The VCI, together with VPI, is used to identify the next destination of a cell as it passes through a series of ATM switches on its way to its destination.Virtual LAN (VLAN)A collection of network nodes that share the same collision domain regardless of their physical location or connection point in the network. A VLAN serves as a logical workgroup with no physical barriers, allowing users to share information and resources located on the same LAN. Virtual Path Identifier (VPI)A 8-bit field in the header of an ATM cell.Wired Equivalent Privacy (WEP)An optional IEEE 802.11 function that offers frame transmission privacy similar to a wired network. The Wired Equivalent Privacy generates secret shared encryption keys that both source and destination stations can use to alter frame bits to avoid disclosure to eavesdroppers.
