Administration of the Avaya G350 Media Gateway - Avaya Support

Chapter 9:Configuring a WAN InterfaceThis chapter provides information about configuring WAN features on the Avaya G350 MediaGateway and contains the following sections:●●●●●●●●●WAN overview — a description of the WAN features supported on the G350Serial interface overview — an overview of serial interfacesInitial WAN configuration — instructions on how to configure a WAN line on the G350Backup interfaces — a description of backup interfaces and how they work on the G350Extended keepalive — a description of the keepalive feature for sending ping packetsthrough an interface at defined intervals to determine if the interface is up or downDynamic CAC — a description of dynamic CAC and how to configure dynamic CAC on aWAN interfaceFrame relay encapsulation — a description of the frame relay encapsulation featuressupported on the G350Priority DLCI — a description of class-based traffic assignment (priority DLCI) and how toconfigure priority DLCI on a WAN interfaceWAN configuration example — an example of a WAN configuration on the G350WAN overviewYou can use an MM340 E1/T1 media module or an MM342 USP media module as an endpointfor a WAN line. You can also use the Fast Ethernet port on the G350 chassis as the endpoint fora WAN line by configuring the Fast Ethernet interface for PPP over Ethernet (PPPoE). TheG350 serves as a router, as well as the endpoint, for the WAN line. For more information aboutrouting, see Configuring the router on page 159.The G350 supports the following WAN features:● PPP over channeled and fractional E1/T1 — the G350 has the ability to map several PPPsessions to a single E1/T1 interface●●●●PPP over USPPPPoEUnframed E1 for enabling full 2.048 Mbps bandwidth usagePoint-to-Point frame relay encapsulation over channelized, fractional, or unframed E1/T1ports or over a USP interfaceIssue 3 January 2005 81
