claiming compliance as a Media Endpoint (Class II) 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.

LLDP-MED Capabilities :
LLDP-MED Capabilities describes the neighborhood unit's LLDP-MED capabilities. The
possible capabilities are:
1. LLDP-MED capabilities
2. Network Policy
3. Location Identification
4. Extended Power via MDI - PSE
5. Extended Power via MDI - PD
6. Inventory
7. Reserved

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 possible application
types are shown below.
1. 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.
2. Voice Signalling - for use in network topologies that require a different policy for the voice
signalling than for the voice media.
3. Guest Voice - to support a separate limited feature-set voice service for guest users and
