How to determine exactly how far/long the phone line is between home/locations and COs are for DSL?

[Ant]

Hello.

Is there a way to determine how far/long the phone line is between homes/locations and COs for DSL online? This is assuming if I have no DSL service.

Thank you in advance. 🙂

The short answer is there is no easy way..

Verizon's engineering department almost certainly has the information, but I don't think there is anyway for you to get it from them.

. If you want to measure it, and don't mind spending a few hundred dollars a  handy device called a Time Domain reflectometer would allow you to measure the distance. Time Domain  reflectometers are mostly used for finding faults in long cables.

a user smith posted a calculation a while ago that was interesting.

With Verizon, the concept is rather simple for an approximation. Open your Transceiver Statistics from the modem and take your downstream Attenuation, and multiply it by 250. You can also take your Upstream attenuation, double it and multiply it by 250 to get an approximation as to where you are feet-wise.

BUT  there are other factors.  SO for example if your line is especially noisy then it adds footage that may not be there in real life. SO you may want to do these calculations with your modem plugged directly into the NID

Ah thanks. I remember DSLreports.com used to have one, but it is closed. I was hoping another web site had one.

Ah, but I forgot to mention that this was without DSL service. 🙂 I wanted to know how far it was.

I don't think it shows distance, but tells you where it is

Yeah, I saw that before but no distance estimater. 😞

The DSLReports Line Distance / Prequal tool has been gone for years. I believe it was around for a short amount of time back when DSL was first getting going before the Telcos started cracking down on API usage and people began getting balled out for using the tool's data to spam others.

As far as the CO locator, gives you the idea on where it is. DSLReports's Service Availability maps a bit more accurate as to where COs may be as they let you zoom into their location. It might not be 100% accurate, but the "CO" marker is usually within 500 feet of where it actually is.

If you're looking for an official count on how long the loop is, you can always ask Verizon. Their database or a Mechanized Loop Test (if it completes) should return a loop length.

Thanks. I will send Verizon and email about the distance. 🙂
