Other Network Considerations

Issue 1 January 2008 27

QoS

For more information about the extent to which your network can support any or all of the QoS

initiatives, see your LAN equipment documentation. See QoS

on page 36 for QoS implications

for 16CC telephones.

All telephones provide some detail about network audio quality. For more information see,

Network Audio Quality Display

on page 27.

IEEE 802.1D and 802.1Q

For more information about IEEE 802.1D and IEEE 802.1Q and the Avaya Agent Deskphone

16CC telephones, see IEEE 802.1D and 802.1Q

on page 36 and VLAN Considerations on

page 82. Three bits of the 802.1Q tag are reserved for identifying packet priority to allow any

one of eight priorities to be assigned to a specific packet.

● 7: Network management traffic

● 6: Voice traffic with less than 10ms latency

● 5: Voice traffic with less than 100ms latency

● 4: “Controlled-load” traffic for critical data applications

● 3: Traffic meriting “extra-effort” by the network for prompt delivery, for example, executive

e-mail

● 2: Reserved for future use

● 0: The default priority for traffic meriting the “best-effort” for prompt delivery of the network.

● 1: Background traffic such as bulk data transfers and backups

Note:

Note: Priority 0 is a higher priority than Priority 1.

Network Audio Quality Display

Users can monitor network audio performance while on a call. For more information, see the

telephone user guide.

While on a call, the telephones display network audio quality parameters in real-time, as shown

in Table 4
