Selecting a Configuration Model PRELIMINARY SELECTING A CONFIGURATION MODEL There are many configuration options for the Megabit Modem 500L from which you can select.
PRELIMINARY Chapter 6: Configuring Sessions CONFIGURING PPP OVER ATM SESSIONS R Y Point-to-Point Protocol (PPP) runs over ATM virtual circuits (VCs). From the EasySession pages, configure parameters for communicating between the modem and the service provider over the WAN (page 36). Then, configure parameters for communicating between the LAN and the modem (page 39).
Configuring PPP over ATM Sessions PRELIMINARY Configuring the WAN Configure the WAN parameters for PPP over ATM sessions between the Megabit Modem 500L and the service provider. Do the following to configure the WAN: R Y 1 Select a name for the service that is descriptive. The service name is an identifier you use for the session and is not used for anything else. Each service name must be unique. When you enter a service name, it displays as the Port name for that session on the EasySession page.
PRELIMINARY Chapter 6: Configuring Sessions Enter the Chap Host name provided by the service provider. The name is used for R Y CHAP authentication of this session. The name must be identical for the user session and for the service provider. See page 73 for the CHAP name you recorded from the service provider.

9 R Y TECHNICAL REFERENCE EL IM IN A This chapter provides technical information about how your modem transmits data between users on your LAN and a service provider over the WAN. TRANSMISSION ON THE WIDE AREA NETWORK The technology is ATM over DMT ADSL that provides the high-speed transmission between the modem and the service provider. This transmission occurs over a single-pair telephone line. The following sections describe these technologies.
PPP PRELIMINARY ATM R Y Asynchronous Transfer Mode (ATM) is a technology that can simultaneously transmit voice, data, and video over ADSL. ATM uses fixed-size cells that transmit over a preestablished connection called a Permanent Virtual Circuit (PVC). Quality of Services can also be specified. EL IM IN A ATM cells are 53 bytes that comprise a 5-byte header and 48-byte payload.
PRELIMINARY Chapter 9: Technical Reference PAP/CHAP Authentication Security R Y Password Authentication Protocol (PAP) and Challenge-Handshake Authentication Protocol (CHAP) are two ways to authenticate PPP sessions. PAP and CHAP are both offered since some systems support only PAP. With PAP, the modem sends authentication requests to the service provider and authentication occurs only once during the life of the link.
Management Protocols PRELIMINARY MANAGEMENT PROTOCOLS R Y SNMP is used to configure system parameters, to monitor statistics, and to perform advanced management tasks. SNMP EL IM IN A This management protocol specifies how to send information between a network management system (NMS) and managed devices on a network. Managed devices run a program called an agent. The agent interprets SNMP requests and responds to them.
PRELIMINARY Chapter 9: Technical Reference MIB and Trap Support Megabit Modem 500L supports the following MIBs: R Y Each managed device has configuration, status, and statistical information that defines its functionality and operational capabilities. These elements make up the MIB for the device being managed. The MIB defines the kind of information an NMS can retrieve from a managed device, and the settings an NMS can control in a managed device.
