GL-12GLOSSARY

____________________________________________________________________________________________________________________________

_

end user	The ultimate source or destination of information flowing through a
	network. It may be an application program, an operator or a physical
	device medium (such as cards or tapes).
Enhanced Uniform Call	An Automatic Call Distribution (ACD) feature that provides, in System 85
Distribution (EUCD)	R2V2, automatic connection of incoming calls to agents who have been
	administered in hunt groups called splits. Calls are distributed using a
	circular hunting algorithm, and features are included to increase agent
	efficiency. See also Automatic Call Distribution and Uniform Call
	Distribution.
error-free second	Any second in which no bit errors occur. Performance for digital signal
	level-1 (DS1) service is measured in error-free seconds.
ESS (electronic switching	A class of modern switching systems developed by AT&T in which the
system)	control functions are performed principally by electronic data processors
	operating under the direction of a stored program. See also
	communications systems and switch.
ETN	See electronic tandem network.
extended superframe (Fe)	A format of 24 frames. See also frame.
framing format
extended trunk access	An arrangement provided at a satellite location in a main-satellite network
(ETA)	whereby calls to extension numbers that are not assigned to that satellite
	are automatically sent to the main switch for interpretation and routing.
facilities restriction level	An assigned number that determines both the kinds of calls that can be
(FRL)	made and the kinds of facilities (trunks) that can be used when calls are
	routed via Automatic Alternate Routing. See also alternate facilities
	restriction level.
facility	The equipment constituting a telecommunications transmission path. See
	also line and trunk.
facility-associated	Signaling in which a D-channel carries the signaling only for those
signaling	channels on the same physical interface. See also nonfacility-associated
	signaling.
FAX (facsimile)	A process, or the result of a process, whereby fixed graphic material is
	scanned and the information converted into electrical signal waves to
	produce an exact likeness.
Fe Framing Format	A format of 24 frames. See frame.
feature	A function or service provided by a hardware or software product.
