DCM476 shows 3 channels down...not 4

I'm not sure why that is. I switched from the 45/4 to the 25/2 package last month, and now have QPSK on channel 4 on the return path.

Thats how it is for most of us.

Normal thing.

Thanks Damir.

I just happened to take a quick look at my stats this morning out of curiousity and noticed the missing channel. Doesn't affect performance and my vmedia IPTV is smooth so I assumed it's SOP.

It has been like this for me since i have cable with start.

Cable Signal Details
Forward Path:
Channel Frequency Power SNR BER Modulation
1 663.0 MHz 3.2 dBmV 40.8 dB 0.000 % 256 QAM
2 615.0 MHz 3.5 dBmV 41.2 dB 0.000 % 256 QAM
3 621.0 MHz 4.0 dBmV 41.2 dB 0.000 % 256 QAM
4 633.0 MHz 3.4 dBmV 41.3 dB 0.000 % 256 QAM
5 639.0 MHz 4.2 dBmV 41.7 dB 0.000 % 256 QAM
6 645.0 MHz 4.2 dBmV 41.3 dB 0.000 % 256 QAM
7 651.0 MHz 4.2 dBmV 41.2 dB 0.000 % 256 QAM
8 657.0 MHz 3.6 dBmV 41.2 dB 0.000 % 256 QAM
Return Path:
Channel ID Frequency Power Modulation
2 30.6 MHz 42.0 dBmV 64 QAM
1 38.6 MHz 42.0 dBmV 64 QAM
3 23.7 MHz 40.5 dBmV 64 QAM
0 0.0 MHz 0.0 dBmV QPSK

Many people reported this here, and nobody is having issues, so, i think its a 'normal' thing

When big red implemented channel bonding, they went for all 4 but from what I gather, they had problems keeping good signal quality across 4 channels, so reduced it to the best 3 channels, even in areas they can't go with 64 QAM. For example, I'm still on 16 QAM upstream.
