Just a general question :D

50 meg is only possible on a d3 modem which has 4 or 8 bondable download channels. Max about 30 meg per channel. Docsis 1.1 uses only 1 download channel so the max you can hit is 38 in a lab under perfect conditions. Fastest i've ever seen on a d1.1 was 35/17 way back when we could force d3 cfg's on a d1.1 cm. Anything over 25 down is respectable on a 51xx series d1.1 modem. Don't get too greedy and your test setup might last awhile....
