reply to cypherstream

Re: I used to follow this guy 12 years ago.

said by cypherstream:

back then it was 1 64QAM downstream and QPSK upstream.

the lower modulation levels back then allowed a more stable connection to poor/noisy transmission lines.
this is one reason why docsis 1.0/1.1 is still currently used on cable boxes for duplex control.
