Incorrect. The physical cable media rate is defined by DOCSIS, but the bridge layer in the CM doesn't necessarily have to forward at full (max) 36Mbit/s rate to be DOCSIS compliant. The compliance only deals with what is and isn't forwarded, how the CM deals with customer equipment, and the signalling used between the CM and CMTS (aka UBR). There's also recommendations on things like LEDs but most vendors appear to ignore these!
