IMC Networks IE-IMCV-T1-MUX/4 operation manual Led

FFL	Fiber Fault Loopback: When the fiber line fails, the Ethernet port
	that is being forwarded over the fiber line is forced out of LINK.
	Similar to the Fiber Alert function.
GUI	Graphical User Interface: Software that provides a visual interface
	to enable an end-user to manage and monitor network devices.
IS	In-Service stat is the normal state of an active port with normal
	error reporting.
LED	Light Emitting Diode: A small stack of lights to indicate link,
	duplex or other options.
LFPT	Link Fault Pass-Through: LFPT can be enabled via iView² or
	through the console port.
LOF	Loss Of Frame: An error condition where the receiver/decoder
	misses detection of the framing signal.
LOS	Loss Of Signal: An error condition where the receiving line
	interface unit does not detect a signal.
MDI/MDIX	Media-Dependent Interface/ Media-Dependent Interface
	Crossover. The ability of an Ethernet port to automatically detect
	and configure its cabling connections to accommodate crossover
	or non-crossover wiring, depending on its link partner and cabling.
MIB	Management Information Base: A database of objects that can be
	monitored by a network management system. Both SNMP and
	RMON use standardized MIB formats that allow any SNMP and
	RMON tools to monitor any device defined by a MIB.
MSA	Multi-Source Agreement (SFP): The standard an SFP must meet to
	be compatible in network devices.
NOC	Network Operations and Control Center
OOS	Out-Of-Service, OOS is used by the CRAFT personnel to turn OFF
	the alarm reporting so they can service the line without causing
	alarm TRAPS to be sent to the NOC Center. The LEDs display a
	line status but do not report any line related alarms back to the
	NOC. A card removal or insertion is still reported, but a PORT
	up/down or changes to its configuration are not.
POP	Point(s) Of Presence: The demarcation point where carrier owned
	equipment is located at the customer site.
