also support all aspects of TIA-1057 applicable to Generic Endpoints (Class I),
and any LLDP-MED Endpoint Device claiming compliance as a Communication
Device (Class III) will also support all aspects of TIA-1057 applicable to both
Media Endpoints (Class II) and Generic Endpoints (Class I).
LLDP-MED Generic Endpoint (Class I)
The LLDP-MED Generic Endpoint (Class I) definition is applicable to all endpoint
products that require the base LLDP discovery services defined in TIA-1057,
however do not support IP media or act as an end-user communication
appliance. Such devices may include (but are not limited to) IP Communication
Controllers, other communication related servers, or any device requiring basic
services as defined in TIA-1057.
Discovery services defined in this class include LAN configuration, device
location, network policy, power management, and inventory management.
LLDP-MED Media Endpoint (Class II)
The LLDP-MED Media Endpoint (Class II) definition is applicable to all endpoint
products that have IP media capabilities however may or may not be associated
with a particular end user. Capabilities include all of the capabilities defined for
the previous Generic Endpoint Class (Class I), and are extended to include
aspects related to media streaming. Example product categories expected to
adhere to this class include (but are not limited to) Voice / Media Gateways,
Conference Bridges, Media Servers, and similar.
Discovery services defined in this class include media-type-specific network
layer policy discovery.
LLDP-MED Communication Endpoint (Class III)
The LLDP-MED Communication Endpoint (Class III) definition is applicable to all
endpoint products that act as end user communication appliances supporting IP
media. Capabilities include all of the capabilities defined for the previous Generic
Endpoint (Class I) and Media Endpoint (Class II) classes, and are extended to
include aspects related to end user devices. Example product categories
expected to adhere to this class include (but are not limited to) end user
communication appliances, such as IP Phones, PC-based softphones, or other
communication appliances that directly support the end user.
Discovery services defined in this class include provision of location identifier
(including ECS / E911 information), embedded L2 switch support, inventory
management

• Application Type Application Type indicating the primary function of the application(s) defined for
this network policy, advertised by an Endpoint or Network Connectivity Device.
The poosible application types are shown below.
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
- for use in network topologies that require a different policy for
the voice signaling than for the voice media.
Guest Voice
- to 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 - for use in network topologies that require a different
policy for the guest voice signaling than for the guest voice media.
Softphone Voice
- for use by softphone applications on typical data centric
devices, such as PCs or laptops.
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
