That's amazing, to me. I would have imagined that ack/rts/cts etc would choke if everything had to be done with only one wire, not just slow down.

Did you go to a website which measures your throughput?

What do you mean by "private line data"?

No I didn't check the speed. Private line data is a dedicated point to point, or multipoint 4 wire data circuit.

Heck you can run a phone line over barbed wire can't ya Justbill !

You bet and did. :thumb:

DJ, I'll presume to answer that one ---- yes, until 1956 the local area had an independent that had magneto ringing --- and, unless you paid extra, you either talked via one side ground or the top strand of barbed wire ---- just don't leave the pasture gate open.

As for the topic :shrug:

If you can't talk on it, what do I know?

Actually had a wire that went up and over gates. At least that's what I heard.

Yeah, there was one down by the creek low water crossing north of Jarbalo. The farmer was complaining of a noisy line --- his field hand had attached the electric fence so it went over the gate. Guess keeping the cows in was more important than a phone call.

:shrug:

I had thought of the telegraph, but didn't think voice could be done, and really didn't think data could be done.
That's funny about the barbed wire phone, but I'll bet the barbed wire didn't have to contend with things like 23:54:23.817524 10.0.0.2.1072 > 10.0.0.1.5001: S 577076198:577076198(0) win 65535 flying back and forth, and resending if one sequence got messed up...
Thanks to everyone for enlightening me, I knew this was the place to find my answer.

Ken,
Actually had line to ground when I started working for the phone company. Out in the sticks were some lines we called "farm lines" owned by the farmers. This was open wire of course and in some cases one side and ground. Lots of times the farmers would run there service over barbed wire after an ice storm until they could pay the phone company to put it back together. Just thought I'd throw that little tid bit in there.

AK, maybe my two cents will help to clear the air. Rember that DSL is a signal, as in a TV channel. You know that you can lose certain channels with cable TV for any reason. It's very simmilar with DSL, since it is just a "channel" on the cable pair that brings in phone service.

The DSL signal is sent using the dedicated voice pairs in the cable. The pair is a metallic path from point A to point B. Since DSL is a signal and not really a circuit, as with the telephone line itself, it uses the copper pair as a private antenna so to speak. The DSL signal simply wiggles it's way to the premises over the cable pair.

If one side of the pair has a fault, it's still possible that the DSL can ride on half a pair. It's as if a water pipe's diameter got cut in half. Slower flow, but it still gets there.

Now, when voice works and DSL doesn't, that's strictly an issue with the head or terminal ends. If the voice circuit is good, then DSL amost has to work unles the distance is too far out.
