Re: Channel bonding?

Thank you. Can bad signal strength effect how many channels a modem bonds with?

The limit on bonding will mainly be on upstream signals. For 1 channel, the limit is 57-58dB. For 2-channel, it's 54-55dB. For 3 or more channels, it's 51-52dB.

Those limits are high. More realistic ranges would be limits before you see possible issues.

Opinion:
1 channel: 54-55 dBmV
2 channels: 52-53 dBmV
3 channels: 50-51 dBmV
4 channels: 48-49 dBmV

The numbers I gave are the maximum from the DOCSIS specs. Ideally, you'd want to stay 4-5 below them.
