Ethernet uses 3 pairs, I think (1 through 6)
Standard "ethernet" can use 2 pairs, or 4, depending on the mode it is running.
In Tierra Nueva many houses have 2 pairs for two phone lines, and 2 pairs for thier data. This allows 10 megabits a second.
Note that 3 levels of hub are allowed
You can have as many levels of hubs as you want, well, within reason. A lan is no different than the internet, there are broadcast stations and media. As long as there is not too much media inbetween 2 broadcast routers (hubs, computers, routers, switches, etc) the signal will perpetuate forever, its like a long chain. Just reading your email you probly went through anywhere between 5 and 15.
You MAY be thinking of various LAN standards and measurments, there are IEEE standards, and 802.xx standards, for example. They are just
I discovered that if you are running 10baseT over cat5 cable, it >>works if the blue & white pair has a phone line on it.
A wire is a wire is a wire. Color is merely for your own organization, in your case, the other end of the line must have been configured in a way that made blue the correct choice.
I'm not competent to answer that. But note that cat5 is by definition unshielded.
There are different kinds of cat5-UTP (unshielded twisted pair), strait cat 5 relies on twisted pairs to cancle out interference. Cat5-STP, or something, is shieled, heavy, thick, and expensive. Note that tierra nueva uses Cat5-E, for extended, increases the range a bit.
