•The DLE32-MAand DLE33-MAmodules each provide 24 fixed 10Base-T switch ports (via RJ45 for the DLE32-MA and RJ21 for the DLE33-MA) and one slot for an optional modular interface that can link the chassis to an FDDI, ATM, WAN, or Gigabit Ethernet backbone. Each modular interface provides frame translation between ATM, FDDI, WAN, Gigabit Ethernet, and Ethernet through an on-board Intel i960 processor:
-The DELHF-UAis an FDDI/Ethernet Translator, which can act as a Single Attached Station (SAS) or Dual Attached Station (DAS) on an external FDDI ring. FDDI Port Interface Modules provide a wide range of media connectivity to the ring. The DELHF-UA also has full-duplex capability, allowing for a 200 Mbps connection to another DELHF-UA.
-The DELHA-UAis an Asynchronous Transfer Mode (ATM) modular interface, which provides an ATM uplink via two media-configurable ATM Port Interface Modules. The dual port interface module design allows for a redundant connection to the uplink, so that if the primary interface fails, the secondary interface will automatically take over. The DELHA-UA acts as an ATM Forum LAN Emulation Client (LEC) so that it can transfer data between devices on an 802.x LAN supported by the MultiSwitch 700 and ATM-connected end stations across a high speed ATM Link. The DELHA-UA adheres to the ATM Forum-approved LAN Emulation (LANE) standard, which defines how end users that rely on existing data communications technology and protocols can operate over an ATM network without penalty.
-The DELHW-UAis a Wide Area Networking (WAN) modular interface, which can provide uplinks to WAN backbones and allow you to perform seamless LAN to WAN switching. The DELHW-UAsupports IP and IPX bridging or routing services, including IP RIP. Multiple WAN connectivity options are supported, including Sync, T1, E1, D&I, ISDN S/T, DDS, and HDSL interfaces, through the use of two configurable WAN port interface modules. Connectivity is available for Point to Point Protocol (PPP), as well as Frame Relay and Leased Lines. Each WAN port interface module can act independently, allowing simultaneous communication, or configured to provide redundant channels if desired.
Unlike other modular interfaces designed for the MultiSwitch 700 boards, the DELHW-UA module functions as an independent intelligent device with its own IP address. As such, it must be managed separately from the MultiSwitch 700 chassis and the board on which it is installed.
The DELHW-UA’s WAN functionality is accessed from the DELHW-UA’s Device View. See The DELHW-UA Device View, on page 2-75of Chapter 2, The MultiSwitch 700 Device View, for instructions on launching the DELHW-UA Device View. Other DELHW-UA Device View functions, such as finding a source address and changing the device time and date, are also described there.
Chapter 7, WAN Configuration, provides information on configuring and managing the WAN capabilities of the various port modules available for the DELHW-UA.
