IPLink Software Configuration Guide
A • Terms and definitions
Mode
The IPLink software CLI is comprised of modes. There are two basic mode
groups, the execution mode group and the configuration mode group.
Network Management System
System responsible for managing at least part of a network. An NMS is
generally a reasonably powerful and well-equipped computer, such as an
engineering workstation. NMSs communicate with agents to help keep
track of network statistics and resources.
Node
Endpoint of a network connection or a junction common to two or more
lines in a network. A Node can be a router, e.g. an IPLink. Nodes, which
vary in routing and other functional capabilities, can be interconnected.
Node sometimes is used generically to refer to any entity that can access
a network, and frequently is used interchangeably with device.
Nodename
Name given to an IPLink or network element.
nvram:
Persistent memory section of an IPLink containing the startup configuration,
the factory configuration and used defined configurations.
Operator
The person who has limited access to the IPLink software CLI.
PCI Local Bus
The PCI Local Bus is a high performance, 32-bit or 64-bit bus with multi-
plexed address and data lines. The bus is intended for use as an intercon-
nect mechanism between highly integrated peripheral controller
components, peripheral add-in boards, and processor/memory systems.
PCM Highway
A 30 channel interface connecting the switching engine with optional
interface cards containing circuit ports.
PMC
The optional interface cards for IPLink series which are compatible to the
PCI Mezzanine Card standards.
PMC Driver Software
PMC driver software performs the runtime tasks on the PMC interface card
mounted in IPLink devices. The PMC drivers are interface card specific
and also have build numbers. Refer to the IPLink software release notes for
PMC driver software compatibility. The PMC drivers may be upgraded
together with the IPLink software release or they can be downloaded indi-
vidually into the persistent memory (flash:) of an IPLink.
PMC Loader
The PMC loader initializes the PMC interface card mounted in IPLink series
of devices. It checks hardware versions and determines if compatible PMC
drivers are available. The PMC loader may be upgraded together with the
IPLink software release.
Port
In IPLink software a port represents a physical connector on the IPLink.
Port Address
A port address can be assigned to a CS interface to realize a virtual voice
tunnel between two nodes.
Post Filter
The voice decoder output is normally filtered using a perceptual post-filter
to improve voice quality. See also
High-Pass Filter
.
POTS
Plain Old Telephone Service
Profile
A profile provides configuration shortcutting. A profile contains specific
settings that can be used on multiple contexts, interfaces or gateways.
Release
IPLink software is organized in releases that define the main voice and
data features of an IPLink. Several builds can be available from certain
release. See also
