Configuration Tool Tab - QoS
You use this screen to enable or disable 802.1 Quality of Service (QoS) support
on the i2050 Software Phone. Since only Windows 2000 supports 802.1, this
screen is not applicable to Windows 98 users.
If you select the setting “Automatic Detection”, the i2050 will decide if 802.1 QoS
should be used. When you select this option, the i2050 will attempt to connect
with 802.1q added to the packets. If the attempt is successful, then the i2050
Software Phone will use 802.1q for the call. If the attempt fails (there is a timeout
after approximately 1 second), the i2050 Software Phone will attempt to connect
again without adding 802.1q to the packets.
Remember that 802.1p/q support requires all the following:
• PC is running Windows 2000.
• Windows QoS Packet Scheduler must be installed and running.
• Nortel Networks i2050 QoS Service must be installed and running.
• Selection of “On” or “Automatic Detection” on the i2050 Configuration
Utility’s QoS Tab.
• Support of 802.1p by the PC’s NIC card.
• Support of 802.1p by the network.
