See the Supporting CD for further information. 8.1 Problems Starting Up the Prestige Table 8-1 Troubleshooting the Start-Up of your Prestige PROBLEM None of the LEDs are on when I turn on the Prestige.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch 8.3 Problems with the LAN Interface Table 8-3 Troubleshooting the LAN Interface PROBLEM CORRECTIVE ACTION I cannot access the Prestige from the LAN. Check your Ethernet cable type and connections. Refer to section 2.2 for LAN connection instructions. Make sure your NIC (Network Interface Card) is installed and functioning properly. I cannot ping any computer on the LAN. Check the 10M/100M LAN LEDs on the front panel.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch 8.5 Problems with Internet Access Table 8-5 Troubleshooting Internet Access PROBLEM I cannot access the Internet. CORRECTIVE ACTION Connect your cable/xDSL modem with the Prestige using the appropriate cable. Check with the manufacturer of your cable/xDSL device about your cable requirement because for some devices may require a crossover cable and others a straight-through Ethernet cable.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch Appendix A PPPoE PPPoE in Action An ADSL modem bridges a PPP session over Ethernet (PPP over Ethernet, RFC 2516) from your PC to an ATM PVC (Permanent Virtual Circuit) which connects to a xDSL Access Concentrator where the PPP session terminates (see the next figure). One PVC can support any number of PPP sessions from your LAN. PPPoE provides access control and billing functionality in a manner similar to dial-up services using PPP.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch How PPPoE Works The PPPoE driver makes the Ethernet appear as a serial link to the PC and the PC runs PPP over it, while the modem bridges the Ethernet frames to the Access Concentrator (AC). Between the AC and an ISP, the AC is acting as a L2TP (Layer 2 Tunneling Protocol) LAC (L2TP Access Concentrator) and tunnels the PPP frames to the ISP. The L2TP tunnel is capable of carrying multiple PPP sessions.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch Appendix B PPTP What is PPTP? PPTP (Point-to-Point Tunneling Protocol) is a Microsoft proprietary protocol (RFC 2637 for PPTP is informational only) to tunnel PPP frames. How can we transport PPP frames from a PC to a broadband modem over Ethernet? A solution is to build PPTP into the ANT (ADSL Network Termination) where PPTP is used only over the short haul between the PC and the modem over Ethernet.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch PPTP Protocol Overview PPTP is very similar to L2TP, since L2TP is based on both PPTP and L2F (Cisco's Layer 2 Forwarding). Conceptually, there are three parties in PPTP, namely the PNS (PPTP Network Server), the PAC (PPTP Access Concentrator) and the PPTP user. The PNS is the box that hosts both the PPP and the PPTP stacks and forms one end of the PPTP tunnel.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch PPP Data Connection The PPP frames are tunneled between the PNS and PAC over GRE (General Routing Encapsulation, RFC 1701, 1702). The individual calls within a tunnel are distinguished using the Call ID field in the GRE header.

Prestige 304 Broadband Sharing Gateway with 4-Port Switch Glossary A ADSL Asymmetrical Digital Subscriber Line is an asymmetrical technology which means that the downstream data rate of the line is much higher than the upstream data rate. ADSL operates in a frequency range that is above the frequency range of voice services, so the two systems can operate over the same cable.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch data communications equipment (DCE) devices. DHCP Dynamic Host Configuration Protocol automatically assigns IP addresses to clients when they log on. DHCP centralizes IP address management on central computers that run the DHCP server program. DHCP leases addresses, for a period of time, which means that past addresses are "recycled" and made available for future reassignment to other systems. DNS Domain Name System links names to IP addresses.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch H Host Any computer on a network that is a repository for services available to other computers on the network. It is quite common to have one host machine provide several services, such as WWW and USENET. HTTP Hyper Text Transfer Protocol. The most common protocol used on the Internet. HTTP is the primary protocol used for web sites and web browsers. It is also prone to certain kinds of attacks.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch L LAN Local Area Network is a shared communication system to which many computers are attached. A LAN, as its name implies, is limited to a local area. This has to do more with the electrical characteristics of the medium than the fact that many early LANs were designed for departments, although the latter accurately describes a LAN as well. LANs have different topologies, the most common being the linear bus and the star configuration.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch relays the PPP frames to the PNS (PPTP Network Server). A PAC must have IP and dial-up capability. POP Post Office Protocol. This is a common protocol used for sending, receiving, and delivering mail messages. Port An Internet port refers to a number that is part of a URL, appearing after a colon (:), directly following the domain name. Every service on an Internet server listens on a particular port number on that server.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch PSTN Public Switched Telephone Network was put into place many years ago as a voice telephone call-switching system. The system transmits voice calls as analog signals across copper twisted cables from homes and businesses to neighborhood COs (central offices); this is often called the local loop. The PSTN is a circuit-switched system, meaning that an end-to-end private circuit is established between caller and the person called.
Prestige 304 Broadband Sharing Gateway with 4-Port Switch Two wires are twisted together to form a pair; the pair form a balanced circuit. The twisting prevents interference problems, STP provides protection against external crosstalk. Straight-through Ethernet cable A cable that wires a pin to its equivalent pin. This cable connects two dissimilar devices, for example, a data terminal equipment (DTE) device and a data communications equipment (DCE) device.
