Hey all,
Been confused about these settings, decided to check them up afer i have been getting slow service sometimes, at around 4-6mbit. Thing is i used to have ntl back in the 512k days with a terayon modem with a little adapter on the back between the line and the modem reducing/increasing the power i think (attenuator). Never had any problems with service in those days but it was only 512k.
Recently i have had 10mbit VM/NTL installed and i asked the engineer about the adapter and he checked it and said i didn't need it, even though no cables or anything have been changed. I was wondering if these settings could explain anything? maybe my reduced speeds sometimes? or is it all due to maintenance and upgrades due to internal network congestion in my case, doesn't help being a student place, oxford.
Cable Modem Downstream

Downstream Symbol Rate : 5056.941 Ksym/sec
Downstream Interleave Depth : taps32Increment4
Downstream Receive Power Level : -11.9 dBmV
Downstream SNR : 29.4 dB - 30.1 db
Cable Modem Upstream
Upstream Lock : Locked

Any help much appreciated, thank you! :)
