host usually implies a PC or workstation, whereas node
generally applies to any networked system, including access
servers and routers. See also node.
Hostname

apply the interface 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
In SmartWare 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
ISoIP
ISDN over IP is patent pending solution of Inalp Networks
AG to carry ISDN services over IP networks.
Jitter
Jitter is the variation on packets arriving on a SmartNode.
See also dejitter buffer.
Mode
The SmartWare CLI is comprised of modes. There are two
basic mode groups, the execution mode group and the
configuration mode group. See Chapter
