SmartWare architecture terms and definitions

Term or Definition	Meaning
Administrator	The person who has privileged access to the CLI.
Application Download	A application image is downloaded from a remote TFTP server to the per-
	sistent memory (flash:) of a SmartNode.
Application Image	The binary operation code stored in the persistent memory (flash:) of a
	SmartNode.
Batchfile	Script file containing instructions to download one or more software com-
	ponent from a TFTP server to the persistent memory (flash: or nvram:) of a
	SmartNode.
Bootloader	The bootloader is a “mini” application performing basic system checks and
	starting the application image. The bootloader also provides minimal net-
	work services allowing the SmartNode to be accessed and upgraded over
	the network even if the application image should not start. The bootloader is
	installed in the factory and is in general never upgraded.
Bootloader Image	The binary code of the Bootloader stored in the persistent memory (flash:)
	of a SmartNode.
Bootstrap	The starting-up of a SmartNode, which involves checking the Reset button,
	loading and starting the application image, and starting other software
	modules, or—if no valid application image is available—the bootloader.
Build	The released software is organized as builds. Each build has its unique
	identification. A build is part of a release and has software bug fixes. See
	also release.
Call Routing	Calls through SmartNode can be routed based on a set of routing criteria.
	See also Session Router.
Call Signaling	The call signaling specifies how to set up a call to the destination Smart-
	Node or 3rd party equipment.
Circuit	A communication path between two or more devices.
Circuit Port	Physical port connected to a switching system or used for circuit switching.
Circuit Switching	The switching system in which a dedicated physical circuit path must exist
	between the sender and the receiver for the duration of the call. Used in
	the conventional telephone network.
Codec	Abbreviation for the word construct Coder and Decoder. Voice channels
	occupy 64 kbps using PCM (pulse code modulation) coding. Over the
	years, compression techniques were developed allowing a reduction in
	the required bandwidth while preserving voice quality. Such compression
	techniques are implemented within a Codec.
