 Configuring Your System

Configuration changes can performed centrally at the boot server:
Ethernet Switch
The SoundPoint IP and SoundStation IP phones contain two Ethernet ports, 
labeled LAN and PC, and an embedded Ethernet switch that runs at full 
line-rate. The Ethernet switch allows a personal computer and other Ethernet 
devices to connect to the office LAN by daisy chaining through the phone, 
eliminating the need for a stand-alone hub. The SoundPoint IP switch gives 
higher transmit priority to packets originating in the phone. The phone can be 
powered through a local AC power adapter or can be line-powered (power 
supplied through the signaling or idle pairs of the LAN Ethernet cable). Line 
powering typically requires that the phone plugs directly into a dedicated 
LAN jack. Devices that do not require LAN power can then plug into the 
SoundPoint IP PC Ethernet port. 
SoundPoint IP Switch - Port Priorities
To help ensure good voice quality, the Ethernet switch embedded in the 
SoundPoint IP phones should be configured to give voice traffic emanating 
from the phone higher transmit priority than those from a device connected to 
the PC port. If not using a VLAN (VLAN set to blank in the setup menu), this 
will automatically be the case. If using a VLAN, ensure that the 802.1p 
priorities for both default and real-time transport protocol (RTP) packet types 
are set to 2 or greater. Otherwise, these packets will compete equally with 
those from the PC port. For more information, refer to
