ISP Information:
The set of colors used in a picture or on a computer screen. Older computers typically used only 16 colors. Modern ones use at least 256 colors, which can be coded by 8 bits of information. With advanced color cards and monitors 65.5 thousand colors (16-bit) or 16 million colors (24-bit) are used. Different web browsers and computer platforms do not necessarily use identical palettes. There is a set of 216 colors that ar

palette - If wires are shorted so that ringer does not ring, thenphone cannot be used for conversation. If wire is open sothat ringer does not ring, then again, phone cannot be usedfor conversation. If phone line can make an outgoing callwithout noise, then phone line is not the problem.Connect modem. Ask someone outside to call in. Disconnectmodem. Ask someone outside to call in again. Use same lineto make outgoing call. Best if phone makes outgoing callconnection through second jack on modem. Results of that testshould isolate (or confuse) problem completely.Too many think eyes will see electrons. Without basic testequipment, no one can identify a failed part.Then the NID. Its function - a demarcation between yourwires and theirs. Open your side, unplug house from theirwires, connect your modem direct to the line - and testwithout anything else in your building to confuse yourthoughts. This procedure so that others can stop posting whatshould be irrelevant possibilities. Is it the modem or not?Do other phones make outgoing calls when modem is and is notconnection? Those are the simple questions.Mark G wrote: Thank you all for your suggestions - I'll do some testing tonight. A few other questions. I've got a multimeter & soldering iron but I'm a novice with each. To summarize what I've heard, my best bet is to isolate the problem to either the 1) modem, 2) the phone line/jack in my house, or 3) some external wiring. To isolate the modem I can use the ohm test. If that fails I could look at replacing the modem or perhaps repairing it...in the case of a circuit that must be resoldered, this should be obvious to me which has been disconnected? If the modem seems to test out OK, them I should test the line/jack. I could do this by repeating the ohm test from the other end of the line with the modem plugged in, or perhaps by plugging my modem into another phone jack and seeing if the problem persists? I think my phone lines are all wired independently to a punch-down block in the basement...not sure if that matters.
