6500PLUS Token Ring Interface Module Option
Introduction
		The Token Ring Interface Module (TRIM) card is an option card that lets you route
		LAN traffic through your network.
Features
		The TRIM card provides the following features:
		• VanguardMS Periphery Routing
		• One Token Ring LAN port operating over Shielded Twisted Pair (STP) or
		Unshielded Twisted Pair (UTP) cable at 16 or 4 Mbps
		• IBM-compatible Source Route Bridging support
		• Support for up to 32 remote LAN bridge connections
		• Capability for Frame Relay, X.25, MX.25, and/or XDLC network connections
		for Token Ring LAN traffic
Description
		You can mount the TRIM card on 6507PLUS or 6525PLUS processor cards (not
		6505PLUS cards) within a Modulus enclosure. The TRIM card is suitable only in a
		Modulus enclosure. A single node can support just one TRIM card. Modulus 8 and
		Modulus 9 enclosures can support one node containing a TRIM card. Modulus 18
		and Modulus 21 enclosures can support a maximum of three nodes containing
		TRIM cards.
		The TRIM card provides one LAN port through its backplane; connection can be
		made through either the unshielded twisted pair (UTP) or the shielded twisted pair
		(STP) LAN connectors. All LAN configuration is performed through Control
		Terminal Port (CTP) menus. See the Vanguard ONS Basics Protocols Manual
		(T0106) for configuration information.
		A PROM chip on the TRIM card provides the BIA (Burned In Address), the LAN
		MAC address unique to that port. The BIA is the default value for the Port TMAC
		Address (found in the Port configuration record).
