• 802.1Q VLAN and 802.1p priority support, industry standards for
managing bandwidth usage
— full VLAN capability, including a manageable integrated switch in
the IP Phone; allows VLAN and priority tagging for the IP Phone
traffic and VLAN tagging for PC traffic
— VLAN filtering which allows the IP Phone to only see Voice VLAN
traffic. The integrated switch will pass DATA VLAN traffic to the
PC Ethernet port. This prevents the Data VLAN broadcast traffic
from reaching the IP Phone. For more information, see
Appendix Appendix B:: "802.1Q VLAN description" on
and Data Networking for Voice over IP (553-3001-160).
