Cabletron Systems EMM-E6 Ethernet manual Pvc, Rmim, Rmon, Sdram

	Protocol to SDRAM
Protocol	A set of rules governing the flow of information within a
	communications infrastructure. Protocols control
	operations such as frame format, timing, and error
	correction. See also Architecture.
PVC	Polyvinyl Chloride. A material commonly used in the
	fabrication of cable insulation. This term is used to
	describe a non-plenum rated insulating material. See also
	Plenum.
Redundant	Extra or contingent. A redundant system is one that is held
	in reserve until an occurrence such as a failure of the
	primary system causes it to be required.
Repeater	A network device consisting of a receiver and transmitter
	which is used to regenerate a network signal to increase
	the distance it may traverse.
RJ45	A modular connector style used with twisted pair cabling.
	The RJ45 connector resembles the modern home
	telephone connector (RJ11).
RMIM	Repeating Media Interface Module. A term used to
	indicate a family of Cabletron Ethernet Media Interface
	Modules (See MIM) which are capable of performing
	their own repeater functions.
RMON	Remote MONitoring. RMON is a network management
	standard which provides more detailed network
	information and status reporting than SNMP.
Router	A router is a device which connects two or more different
	network segments, but allows information to flow between
	then when necessary. The router, unlike a bridge,
	examines the data contained in every packet it receives for
	more detailed information. Based on this information, the
	router decides wether to block the packet from the rest of
	the network or transmit it, and will attempt to send the
	packet by the most efficient path through the network.
SDRAM	Shared Dynamic Random Access Memory.
