SmartWare architecture terms and definitions
A region in the persistent memory of a SmartNode. See also flash mem-
ory .
Gatekeepers manage H.323 zones, which are logical collections of
devices such as all H.323 devices within an IP subnet. For example, gate-
keepers provide address translation (routing) for the devices in their zone.
A gateway refers to a special purpose component that connects two con-
texts of different types, For example, the CS and the IP context. It handles
connections between different technologies or protocols. SmartWare
includes an H.323 and SIP gateway.
ITU-T recommendation H.323 describes terminals, equipment and services
for multimedia communication over Local Area Networks (LAN) which do
not provide a guaranteed quality of service. H.323 terminals and equip-
ment may carry real-time voice, data and video, or any combination,
including video telephony.
H.323 registration authentication service (RAS) is a sub protocol of
H.323. The RAS signaling protocol performs registration, admissions, and
bandwidth changes and disengage procedures between the VoIP gate-
way and the gatekeeper.
A high-pass filter is normally used to cancel noises at the voice coder
input. See also post filter
Computer system on a network. Similar to node, except that host usually
implies a PC or workstation, whereas node generally applies to any net-
worked system, including access servers and routers. See also node .
Name given to a computer system, e.g. a PC or workstation.
In SmartNode terminology, a hunt groups allows you to apply the inter-
face configuration to multiple physical ports. Within the hunt groups free
channels for outgoing calls are hunted on all available ports. In general a
hunt group represents a group of trunk lines as used for direct dialing in
(DDI).
An interface is a logical construct that provides higher-layer protocol and
service information. An Interface is configured as a part of a context, and
is independent of a physical port or circuit.
An optional plug-in card offering one or more ports of a specific physical
standard for connecting the SmartNode to the outside world.
Integrated Services Digital Network
ISDN Services comprise voice, data, video and supplementary services.
Supplementary services are services available in the ISDN network, such
as calling line identification presentation (CLIP) or call waiting (CW). See
also Q.SIG
Jitter is the variation on packets arriving on a SmartNode. See also dejitter
buffer .
The CLI is comprised of modes. There are two basic mode groups, the exe-
cution mode group and the configuration mode group.
