![]() "Nigel M" wrote in message ... Finally got broadband yesterday, and I've been having a look at my router's logs. Three things I noticed, as follows: Operation Data Upstream Downstream Noise Margin 31 dB 31 dB Attenuation 28 dB 25 dB Defect Indication Indicator Name Near End Indicator Far End Indicator Fast Path CRC Error 7 0 Router is 3Com 3CRWDR100A-72, ISP is Pipex. Are the noise and attenuation figures about right? What is the Fast Path CRC Error? Anything to worry about? Can anyone suggest a resource about this sort of data? -- Nigel M "Time may be a great healer, but he's a lousy beautician" Hi Nigel, I don't know about the CRC figures but the noise margin must be more than about 10 or 12dB, in fact, the higher the better, so you're fine with those figures. The attenuation has to be no more than about 60dB for the 1Mb service and no more than 41dB for the 2Mb, so you'll be OK for the faster services as they come along. Mogweed. |
