Unusual upstream frequencies
I've mentioned this in passing in a different thread.

This week the New Malden CMTS upgrades started to happen - I was moved to a new CMTS as part of this work and went from 12 to 16 down stream channels.

Upstream stayed the same, but not sure if modulation changed to 64 QAM as the Hitron business hub doesn't display that.

What I do find is the frequencies of the upstreams are varying a bit - this didn't happen before. Previously all frequencies ended in 00000 but now I get varying ones show below. Is this normal?

Performance upstream is slightly worse since the changes.

Upstream Overview
Port Frequency (Hz) BandWidth Modulation Power (dBmV) Channel
1 30999944 6400000 ATDMA 39.750 2
2 37599954 6400000 ATDMA 43.250 1
