Term or Definition

Meaning

 

 

flash:

A region in the persistent memory of a SmartNode. See also flash mem-

 

ory.

 

 

Gatekeeper

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.

 

 

Gateway

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.

 

 

H.323

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 RAS

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.

 

 

High-Pass Filter

A high-pass filter is normally used to cancel noises at the voice coder

 

input. See also post filter

 

 

Host

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.

 

 

Hostname

Name given to a computer system, e.g. a PC or workstation.

 

 

Hunt Group

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).

 

 

Interface

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.

 

 

Interface Card

An optional plug-in card offering one or more ports of a specific physical

 

standard for connecting the SmartNode to the outside world.

 

 

ISDN

Integrated Services Digital Network

 

 

ISDN Services

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

Jitter is the variation on packets arriving on a SmartNode. See also dejitter

 

buffer.

 

 

Mode

The CLI is comprised of modes. There are two basic mode groups, the exe-

 

cution mode group and the configuration mode group.
