And just to be accurate, you should multiply by 1000, not 1024. Bit rates always come in thousands.

Yes I did, corrected.

Bit rates ? A long standing argument I guess.
Most computer people (in my experience) still use MB for 1024 x 1024, and not the stupid Men in Black (MiB).

No argument. Random access memory sizes are multiples of 1024 because of the addressing mechanism, but comms speeds and hard drive sizes are and always have been multiples of 1000.

I'm with you on "MiB" though. Totally unnecessary.

Re: 5 Upstream channels

They are removing 25.8 for now as it's closer to the noise floor

Re: 5 Upstream channels

1 of my 16QAM channels is on 25.8, so does that mean i'll end up with one 32/64 but the rest will stay 16....

Mine is also so maybe it is very common.

All times are GMT +1. The time now is 15:54.
