SmartWare Software Configuration GuideA • Terms and definitions

Term or Definition	Meaning
Comfort Noise	Comfort noise is generated at the remote end of the silent direction to
	avoid the impression that the connection is dead. See also Silence Com-
	pression.
Command Line Interface	An interface that allows the user to interact with the SmartWare operating
	system by entering commands and optional arguments. Other operating
	systems like UNIX or DOS also provide CLIs.
Configuration Download	A configuration file is downloaded from a remote TFTP server via TFTP to
	the persistent memory (nvram:) or volatile memory (system:)of a Smart-
	Node.
Configuration File	The configuration file contains the CLI commands, which are used to con-
	figure the SmartNode.
Configuration Server	A central server used as a store for configuration files, which are down-
	loaded to or uploaded from a SmartNode using TFTP.
Configuration Upload	A configuration file is uploaded from the persistent memory (nvram:) or
	volatile memory (system:) of a SmartNode via TFTP to a TFTP server.
Context	Represents one specific networking technology or protocol, e.g. IP or cir-
	cuit switching.
Data Port	Physical port connected to a network element or used for data transfer.
Dejitter Buffer	The element used to compensate variable network delays. Storing packets
	in a dejitter buffer before they are transferred to the local ISDN equip-
	ment, e.g. telephone, a variable delay is converted into a fixed delay, giv-
	ing voice a better quality. See also Jitter.
Digit Collection	Some devices (PBX, ISDN network, remote gateways and gatekeepers)
	may require bloc sending of the dialed number. Digit collection collects
	the overlap dialed digits and forwards them in a single call setup message
Driver Software Download	A driver software image is downloaded from a remote TFTP server to the
	persistent memory (flash:) of a SmartNode.
Driver Software Image	The software used for peripheral chips on the main board and optional
	PMC interface cards is stored in the persistent memory (flash:) of a Smart-
	Node.
DTMF Relay	DTMF relay solves the problem of DTMF distortion by transporting DTMF
	tones over low-bit-rate codecs out-of-band or separate from the encoded
	voice stream
Echo Canceller	Some voice devices unfortunately have got an echo on their wire. Echo
	cancellation provides near-end echo compensation for this device.
Factory Configuration	The factory configuration (factory-config) represents the system default set-
	tings and is stored in the persistent memory (nvram:) of a SmartNode.
Fast Connect	A “normal” call setup with H.323 requires several TCP segments to be
	transmitted, because various parameters are negotiated. Since a normal
	call setup is often too slow, fast connect is a new method of call setup that
	bypasses some usual steps in order to make it faster.
Flash Memory	Persistent memory section of a SmartNode containing the Application
	Image, Bootloader Image and the driver software Image.
