What is an SDSL Modem? 1-3protocols as well as bridging, with support for learning bridge and802.1d spanning tree functionality to eliminate loops. Other importantfeatures include: Routing Information Protocol (RIP), Simple NetworkManagement Protocol (SNMP), address translation, telnet, and packetfiltering. The web browser-based OfficeConnect Remote 840 Managerand the IP Wizard provide a user-friendly configuration interface.To simplify the installation process, the OfficeConnect Remote 840 can beinitialized with pre-configured parameters using DIP switches located onthe back of the unit. There are three operational modes: DHCP SmartMode, Default Bridge Mode, and Unconfigured Mode.What is an SDSLModem?An SDSL modem is a device that transmits and receives data throughregular telephone lines at speeds that far exceed traditional analogmodem technology.It allows your workstation to connect to a remote site using a networkprotocol such as IP or IPX. The OfficeConnect Remote 840 contains oneSDSL modem port which is the WAN interface.What is ATM? Asynchronous Transfer Mode (ATM) is a modern networking technologythat provides support for a wide variety of services and applications. TheOfficeConnect Remote 840 provides support for ATM over SDSL.ATM is based on the transfer of fixed-length cells containing a headerand an information field. The header is used to route the cells throughthe ATM network backbone.ATM defines connections by two main parameters, which are explainedlater in this Guide: Virtual Path Identifier (VPI) Virtual Channel Identifier (VCI).What is FrameRelay?Frame Relay is a framed-based technology that runs over HDLC (HighLevel Data Link Control). Virtual Circuits are defined which connect theOfficeConnect Remote 840 to up to 16 remote sites within a Frame RelayNetwork. Each Virtual Circuit is identified by a Data Link ConnectionIdentifier (DLCI), which is included in the frame header.840ug.book Page 3 Friday, July 7, 2000 2:23 PM
