About the Vanguard 300/305 Overview The Vanguard 300/305 The Motorola Vanguard 300/305 Frame Relay Access Device (FRAD) provides serial devices with LAN Ethernet (Vanguard 300) or Token Ring (Vanguard 305) access into public or private Frame Relay networks. The FLASH-based Vanguard 300/305 is available in FRAD, mono FRAD, or duo FRAD configurations with either two or three serial ports and an abundant list of protocol choices. You can order the base unit with an integral DSU and a software application package, making this low-cost FRAD an economical choice for connecting remote LAN sites with both LAN and Serial traffic to public Frame Relay services. You can also configure extra serial ports on the mono and duo FRAD to provide a backup link to the Frame Relay network port. Or, you can connect them to an external analog dial modem, SW56 DSU or ISDN BRI TA, to provide an alternate path in case of network failure. Example of the Vanguard 300/305 The Vanguard 300/305 is available either with or without an integral DSU daughtercard or DIM Site daughtercard in a desktop-size standalone enclosure, as shown in Figure 1-1.
