-=PCTechTalk=- Re: Cable Modem - Again!

53 dbmv does NOT neccessarilly mean there is a high noise level, it simply is a 
measure of the carrier output level the modem is using to 'talk' back to the 
cable company hardware. Noise is only one possible reason, a more common reason 
is LOSS in the line
& splitters between your modem and the corrisponding cable company modem, this 
is typically due to improper/defective splitters, poor connections, excessive 
cable lengths, wrong cable type, water/moisture in the cable system, etc.

Half the problem is the suppossed cable tech's don't understand the term's 
themselves and or how the signal levels are affected by the cable system, and 
to top it off lot's of tech's can't explain this stuff either and they just 
throw around some of the
jargon to impress the users, nothing like having to BS your customers and 
getting paid for it.

To round this out, there are of course some good tech's in most cable 
companies, their the one's that get called out about the 10th time you complain 
about it not working.
