-
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, it does 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, it 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 products.
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, and inventory
management.
