Is ADSL broadband polarity-sensitive?

[packman 0]

Is the connectivity of ADSL broadband wires polarity-sensitive? In other words, if the polarity of the two wires arriving at your modem from the local exchange happens to be the wrong way around, will the connection work less well?

 

It's certainly the case that dial-up is polarity-sensitive, as I confirmed that with mine.

 

I suspect that it's more sensitive the further away you're situated from the exchange.

 

Has anyone any convincing arguments on this? ADSL is supposed to be 'assymetrical', after all, isn't it?

The "asymmetrical" part of ADSL refers to the differing upstream and downstream speeds - SDSL services have the same speed both upstream and downstream.

I'm not aware that ADSL is polarity sensitive, maybe you might be able to find something on ADSLGuide that will answer your question.

Thanks Andy. That's quite informative.

 

Actually, I already knew of the existence of that ADSL Guide website and found nothing there that touches on the issue of polarity sensitivity.
