Introduction to Netlink Frame Relay Access Devices
Cabletron's Netlink
™
family is designed to provide a comprehensive method of inte-
grating LAN-based systems and wide-area applications into a "blended" network.
Ranging from the FRX4000 network access node to the FRX8000 backbone switch,
each Netlink device can be a fully capable LAN router and a robust switch supporting
multiple access and routing protocols. FRX7000 and FRX8000 are documented in
separate manuals. The remaining products—FRX4000, FRX6000, and the Netlink
Frame Relay Module (FRM) for the MMAC-Plus

FRX4000, FRX6000, and FRM are generally used to provide concentration and
access to remote devices. FRX4000 is a stand-alone device used where eight serial
interfaces or fewer are required. FRX6000 is a larger stand-alone device supporting
up to sixty-four serial interfaces, and can function as a central-site device for remote
FRX4000s or FRMs. The FRM is an 8-port module mounted into a Cabletron
MMAC-Plus chassis. (FRMs do not interact with other modules in the MMAC-Plus,
with the exception of a cable connection to a LAN interface module in the MMAC-
Plus, which provides LAN connectivity to the WAN interfaces on the FRM.)

FRX and FRM devices provide local and remote switching, and (on devices with
video interfaces) feature an intuitive, menu-based management structure that allows
complete local and remote control of other FRX/FRM devices.
