Re: Question on the Maximum number of packets per second




Tim,

Where, in the resolution that was passed in St Louis, was additional 
compensation added to the rate adaptation to compensate for a system clock 
running at +100PPM and a transmitter with another clock operating at 
+20PPM?  That is a total compensation delta between the MAC Client/RS and 
the WIS of 120PPM.  From what I understand, the current rate adaptation 
scheme was based on the system clock and the WIS clock being the same.

Thank you,
Roy Bynum
