Errrm, that doesn't look right.

What capabilities does this system claim to have?  Does it really have
Home-PNA?  Does it have an add-on transceiver board for 100baseTx, and
do you have that option?

This is the correct interpretation of that media table entry.

The transceiver either doesn't exist, or hasn't been activated.
