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.
