2.5.4. IGMP
The ‘IG MP ’ group includes controls to disable the query timeouts. C hecking the ‘O verride D efaults’ box will enable
the other boxes as choices.
2.5.5. Priority TTL Value
The ‘P riority TTL Value’ determines the life span (Time to live) of each packet in the buffer of the AV device that will
be sent over the powerline subsequently. This value can be varied from 10 msec to 65000 msec which can be
mapped to different levels of C hannel access priority traffic. The default values used are stored in the P IB file as
shown below:
C A 0 traffic: 2000 msec (used for TC P data traffic)
C A 1 traffic: 2000 msec (used for TC P data traffic)
C A 2 traffic: 300 msec (used for U D P video/music traffic)
C A 3 traffic: 300 msec (used for VoIP traffic)
Intellon highly recommends that the 300 msec and 2000 msec default settings not be changed because they are
optimized for the above stated traffic.
