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
