Docsis 3.1 question

Why is only 1 docsis 3.1 channel in use and why does it almost always have uncorrectables?

I'll presume you have a DOCSIS 3.1 modem.  Did you notice the 32 Downstream QAM channels?  QAM channels used to be single channels (SC-QAM) separated by "guard bands."

With D3.1, although you see only 1 OFDM channel, it's 1 channel divided into 32 QAM channels but with orthogonal separation.

    @Dlabit29, It is common to see some errors in the modem logs. Are you having issues with the service? -Allan, Cox Support Forums Moderator.
