*) These values are still within the 802.3af PD class 3, which allows up to 12,95 W, but they
are averaged, not maximum values. As soon as the USB interface is used, PD class 3 is
exceeded. Therefore, an external power supply has to be used for an OpenStage 60G/80G
with 2 Key Modules.
Connecting OpenStage Phones to the IP Network
802.1x
OpenStage phones support 802.1x EAP-TLS. Certificates for authentication can be
downloaded via the WPI.
LLDP-MED Configuration Options
OpenStage SIP phones support the layer 2 protocol LLDP-MED (Link Layer Discovery Protocol-
Media Endpoint Discovery). It is used for simplification of auto-configuration and network
management. The auto-configurable parameters of OpenStage phones are mainly the VLAN
ID, power consumption (power class) and quality of service (QoS) parameters.
LLDP-MED is able to replace various other established mechanisms like DHCP options,
manual configuration, or proprietary solutions like Cisco CDP. Example parameters are LAN
speed and duplex discovery, network policy discovery (VLAN and QoS capabilities) or
extended power via MDI discovery (PoE).
When an OpenStage phone is connected to a switch with LLDP-MED capabilities, the phone
is able to
a) advertise and receive a VLAN ID,
