Description: This attribute defines whether pre-equalization is enabled on the associated OFDMA upstream channel.
What is docsIf31CmUsOfdmaChanPreEqEnabled?
A true/false flag indicating whether pre-equalization (the modem pre-distorting its upstream signal to compensate for known plant impairments) is enabled on this OFDMA upstream channel. Admins check this when troubleshooting upstream signal quality, since a channel with pre-equalization disabled will be more sensitive to micro-reflections and other linear plant distortions.
