 Application Type
User's Manual of GS-5220-24T4XV(R) Managed LCD Switch
Intended use of the application types:

Voice - for use by dedicated IP Telephony handsets and other similar
appliances supporting interactive voice services. These devices are
typically deployed on a separate VLAN for ease of deployment and
enhanced security by isolation from data applications.

Voice Signaling (conditional) - for use in network topologies that
require a different policy for the voice signaling than for the voice
media. This application type should not be advertised if all the same
network policies apply as those advertised in the Voice application
policy.

Guest Voice - support a separate 'limited feature-set' voice service for
guest users and visitors with their own IP Telephony handsets and
other similar appliances supporting interactive voice services.

Guest Voice Signaling (conditional) - for use in network topologies
that require a different policy for the guest voice signaling than for the
guest voice media. This application type should not be advertised if all
the same network policies apply as those advertised in the Guest
Voice application policy.

Softphone Voice - for use by softphone applications on typical data
centric devices, such as PCs or laptops. This class of endpoints
frequently does not support multiple VLANs, if at all, and are typically
configured to use an 'untagged' VLAN or a single 'tagged' data specific
VLAN. When a network policy is defined for use with an 'untagged'
VLAN (see Tagged flag below), then the L2 priority field is ignored and
only the DSCP value has relevance.

Video Conferencing - for use by dedicated Video Conferencing
equipment and other similar appliances supporting real-time
interactive video/audio services.

Streaming Video - for use by broadcast or multicast based video
content distribution and other similar applications supporting streaming
video services that require specific network policy treatment. Video
applications relying on TCP with buffering would not be an intended
use of this application type.

Video Signaling (conditional) - for use in network topologies that
require a separate policy for the video signaling than for the video
media. This application type should not be advertised if all the same
network policies apply as those advertised in the Video Conferencing
application policy.
