Re: Internet having issues after upgrading cable service
its my understanding the CMTS unit CV is using "instructs" subscriber modems what US RF power level to operate at, hence why a duplex amplifier installed at the subscribers home where the US RF level is normal, will always provide inaccurate out of specification US RF levels on the diagnostic page of the subscribers modem/cable box.
so, if the US RF level is within spec (without a duplex amp) but the DS RF is out of spec, theres obviously an issue at the CMTS.
additionally, if the CMTS is receiving more than a fixed % of subs reporting "poor signal received", the CMTS will "up" is outgoing RF level by fixed increments until it is "satisfied".
