General discussion

no DSL in a DSL area

May 17, 2007 5:04AM PDT

A friend of mine is trying to get DSL on his phone line. He was told by ATT that he could, but when he was ready to go, they canceled his service, saying that there was "too much loading on the line."

What does that mean?

Also, he has a second phone line. ATT said that they could connect DSL to that line, then remove the phone service. He agreed.

But, again, just before he was about to get the DSL configured, they also canceled that order, with the same "too much loading on the line."

Again, what does this mean? Thanks.

I've heard that.

The home owner had no less than 50 phones in the house. It was amazing that it would ring!

Do they have a lot of stuff plugged in?

Second line is open
May 17, 2007 8:53AM PDT

On the second line, only a single phone. And, they told him that they could connect the DSL, then they would remove the phone service from that line, so the only thing on the line would be the internet signal.

I don't know about the other ones, but knowing him, probably not more than a couple of phones, maybe 3.

It's the second line that is free and clear. Plus, there is DSL service available in the area, so it doesn't appear to be distance-related.

Then read this FAQ.

Load coils. . .
May 18, 2007 10:22PM PDT

Have been in existence since the first long distance phone lines. Invented by Charles Wheatstone in the early years of the 20th century.

A load coil is a device that equalizes frequency drop off on analog phone lines. It enables the specific voice frequencies of 200-3400 Hz. to travel longer distances over the cable pair with less distortion. In cable loading, load coils are placed every 6,000 feet in the cable run. They also have the inherent property of a band-pass filter. They pass the voice frequencies but block higher frequencies. Since ADSL is an analog signal with a bandwidth of 80 KHz. to 1.1 MHz, load coils block the signal. For DSL to work on a phone line, the load coils must be removed.
