What is an SDSL Modem?
1-3
protocols as well as bridging, with support for learning bridge and
802.1d spanning tree functionality to eliminate loops. Other important
features include: Routing Information Protocol (RIP), Simple Network
Management Protocol (SNMP), address translation, telnet, and packet
filtering. The web browser-based OfficeConnect Remote 840 Manager
and the IP Wizard provide a user-friendly configuration interface.
To simplify the installation process, the OfficeConnect Remote 840 can be
initialized with pre-configured parameters using DIP switches located on
the back of the unit. There are three operational modes: DHCP Smart
Mode, Default Bridge Mode, and Unconfigured Mode.
What is an SDSL
Modem?
An SDSL modem is a device that transmits and receives data through
regular telephone lines at speeds that far exceed traditional analog
modem technology.
It allows your workstation to connect to a remote site using a network
protocol such as IP or IPX. The OfficeConnect Remote 840 contains one
SDSL modem port which is the WAN interface.
What is ATM?
Asynchronous Transfer Mode (ATM) is a modern networking technology
that provides support for a wide variety of services and applications. The
OfficeConnect Remote 840 provides support for ATM over SDSL.
ATM is based on the transfer of fixed-length cells containing a header
and an information field. The header is used to route the cells through
the ATM network backbone.
ATM defines connections by two main parameters, which are explained
later in this Guide:
■
Virtual Path Identifier (VPI)
■
Virtual Channel Identifier (VCI).
What is Frame
Relay?
Frame Relay is a framed-based technology that runs over HDLC (High
Level Data Link Control). Virtual Circuits are defined which connect the
OfficeConnect Remote 840 to up to 16 remote sites within a Frame Relay
Network. Each Virtual Circuit is identified by a Data Link Connection
Identifier (DLCI), which is included in the frame header.
