Cisco DPQ3212 DOCSIS 3.0 2-PORT Voice Modem (we don't use the voice part).
Upstream channels are:
Channel 1: 44.5 dBmV
Channel 2: 44.7 dBmV
Channel 3: 0.0 dBmV
Channel 4: 45.2 dBmV
Channel 3 looks suspect, especially given that I get pretty frequent packet loss (between 2 and 8%, typ.) at various times during the day coupled with low upload rates (1M); mostly in the evening, as measured by smokeping and my gaming console multiplayer test.
Also, although S/N levels look ok, downstream power levels look low - shouldn't these be closer to 0dBmV?
Channel 1: -9.0 dBmV 38.2 dB
Channel 2: -8.6 dBmV 38.4 dB
Channel 3: -9.3 dBmV 37.8 dB
Channel 4: -9.5 dBmV 38.3 dB
Channel 5: -8.6 dBmV 38.5 dB
Channel 6: -8.5 dBmV 38.6 dB
Channel 7: -8.4 dBmV 38.2 dB
Channel 8: -8.7 dBmV 38.7 dB
Any advice appreciated.
thanks,
