Content Slider The Scopia
®
Content Slider stores the data already presented in the
videoconference and makes it available for participants to view during the
meeting.
Continuous
Presence
Continuous presence enables viewing multiple participants of a
videoconference at the same time, including the active speaker. This
graphics-intensive work requires scaling and mixing the images together
into one of the predefined video layouts. The range of video layouts
depends on the type of media processing supported, typically located in the
MCU.
Control
Control, or media control, sets up and manages the media of a call (its
audio, video and data). Control messages include checking compatibility
between endpoints, negotiating video and audio codecs, and other
parameters like resolution, bitrate and frame rate. Control is communicated
via H.245 in H.323 endpoints, or by SDP in SIP endpoints. Control occurs
within the framework of an established call, after signaling.

Dedicated Endpoint A dedicated endpoint is a hardware endpoint for videoconferencing
assigned to a single user. It is often referred to as a personal or executive
endpoint, and serves as the main means of video communications for this
user. For example, Scopia
®
XT Executive. It is listed in the organization's
LDAP directory as associated exclusively with this user.
Delivery Node
The Avaya Scopia
®
Streaming and Recording Delivery Node provides on-
demand and broadcast video delivery. You can use it alone or in a
hierarchy of devices. It supports thousands of concurrent streams. The
Delivery Node uses intelligent routing, content caching, and inherent
redundancy to ensure transparent delivery of high-quality video.
Dial Plan
A dial plan defines a way to route a call and to determine its characteristics.
In traditional telephone networks, prefixes often denote geographic
locations. In videoconferencing deployments, prefixes are also used to
define the type and quality of a call. For example, dial 8 before a number for
a lower bandwidth call, or 6 for an audio-only call, or 5 to route the call to a
different branch.
Dial Prefix
A dial prefix is a number added at the beginning of a dial string to route it to
the correct destination, or to determine the type of call. Dial prefixes are
defined in the organization's dial plan. For example, dial 9 for an outside
line, or dial 6 for an audio only call.
Distributed
Deployment
A distributed deployment describes a deployment where the solution
components are geographically distributed in more than one network
location.
