@ Home signal strength

[cctodd]

I was told to have -3 to +3 at the modem. Is that at the frequency the modem is locked at, or is it ?

No what that is, is your signal strength in decibals your cable modem it needs a certain amount of signal in order to funtion.

[cctodd]

I know that,what I'm asking is the -3 to +3 on the frequency the modem is locked at, or is the -3 to +3 being checked around some certain channels. I have good signal at my modem.

And the frequency is the channels that it uses for sending/receiving.

[glc1]

cctodd, are you having problems w/ your connection?

[cctodd]

No problems glc1 just asking. I work with a communcations company and we went with @home. We where told to have -3 to +3 at modem. My question is that at the frequency my modem is locked at.

+/-3dB is a narrow window for the signal level. It can be achieved though. The modems will work from -15 to +15dB. If you want to know the frequency you could ask the local provider. Don't call @HOME because they probably wouldn't know. Depending on the type of modem you have, you might be able to look up the self-diagnostic page on the modem. That would tell you the upstream and downstream frequency.

I am wondering, why do you need to know the frequency? Also keep in mind that there are 2 frequencies here.

Yes,it is at the frequency the modem is locked.MtCableman is right though they have a much wider operating range.
