Set the switch to MDI-X when connecting to a hub or router. • Check that you are using a Web browser (Netscape or Internet Explorer) Version 4.0 or newer.
TECHNICAL REFERENCE 10 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 ATM over DMT ADSL is the technology 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.
Transmission on the Wide Area Network ATM 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 Service provides UBR. ATM cells are 53 bytes that comprise a 5-byte header and 48-byte payload.
Chapter 10: Technical Reference SYSTEM MODE ENCAPSULATION Point-to-Point Protocol (PPP) over ATM or RFC 1483 Bridging/Routing are the two protocols you can use to encapsulate data for transport across the ADSL WAN. The following sections describe these protocols. PPP PPP runs over ATM virtual circuits. PPP exists between the hardware layer and the network-layer interface protocols. It is a widely used protocol for establishing connections on the WAN.
System Mode Encapsulation NAPT does not have the limitation of using only the IP address in the translation. It also uses TCP/UDP ports. It is a method that allows multiple IP addresses and their TCP/UDP ports to be translated into one IP address and its ports. A good candidate for NAPT is a small office with multiple hosts but one public IP address. In this case, NAPT allows the entire office to use the public IP address to communicate out of the private network.
Chapter 10: Technical Reference Example LAN Physical Network This physical configuration is valid only when used with Spanning Tree to eliminate loops.
System Mode Encapsulation Routing You can configure the Megabit Modem 400F and 700F router to route Ethernet-encapsulated IP datagrams based on IP addresses. Use Routing Information Protocol (RIP) to automatically identify the route from the session on the Megabit Modem 400F and 700F to the destination. You can specify the direction and version of RIP that allows other routers to update their routing tables automatically (for example, information on how many hops between destinations).
Chapter 10: Technical Reference MANAGEMENT PROTOCOLS SNMP is used to configure system and bridge parameters, to monitor statistics, and to perform advanced management tasks. SNMP 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.
Management Protocols MIB and Trap Support 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.
Chapter 10: Technical Reference DNS RESOLUTION If you want Domain Name System (DNS) resolution, you need to specify the IP address for a device to be the DNS resolver. You can also specify another IP address to designate a second device for a secondary DNS resolver. The DNS device maps human-readable addresses to IP addresses. A human-readable address is one such as maggie.copro.company.com that contains a host name and domain.

Encapsulation ENCAPSULATION Selection of an encapsulation protocol from the modem to the service provider occurs on a per virtual circuit (session) basis. For example, for the 700F you can configure 32 sessions for PPP over ATM mode and configure another 32 sessions for RFC 1483 mode. However, you can activate only PPP over ATM sessions or RFC 1483 sessions at a time. You cannot concurrently activate PPP sessions and RFC 1483 sessions for all Megabit Modems.
