Ieee 802.1D And 802.1Q; Displaying Network Audio Quality - Avaya 9608 Administration

IEEE 802.1D and 802.1Q

For more information about IEEE 802.1D and IEEE 802.1Q and the 9600 Series SIP IP
Telephones, see
identifying packet priority to allow any one of the following eight priorities to be assigned to a
specific packet:
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
●
2: Reserved for future use
●
3: Traffic meriting "extra-effort" by the network for prompt delivery, for example, executive
●
e-mail
4: "Controlled-load" traffic for critical data applications
●
5: Video traffic with less than 100ms latency and jitter
●
6: Voice traffic with less than 10ms latency and jitter
●
7: Network management traffic
●
Note:
Priority 0 is a higher priority than Priority 1.

Displaying network audio quality

All 9600 Series SIP IP Telephones give the user an opportunity to monitor network audio
performance while on a call. The Network Information screen in the Avaya menu on the
deskphone displays this information. Access the Network Information screen from the Avaya
(A) Menu and select the Network Information option directly. On touchscreen deskphones,
access the Home Screen, then select Settings, then Network Information. While on a call, the
Deskphones display network audio quality parameters in real-time, as shown in the following
table.

Possible Values
G.711, G.722, G.726A, or G.729.
No data or a percentage. Late and out-of-sequence packets are
counted as lost if they are discarded. Packets are not counted
as lost until a subsequent packet is received and the loss
confirmed by the RTP sequence number.
