Hello Folks,
After two frustrating hours on the phone with my ISP, dodging their
excuses and their "Oh, it's got to be this other problem" I want to be
able to diagnose some DSL stuff for myself. IOW measure DSL signal
levels versus noise. AFAIK there is a pilot tone at 276kHz or sometimes
138kHz for downstream and another one at 69kHz for upstream.
Question: What are the min-max levels for those pilot tones?
Reason why I want to be able do that is the extreme wait on the phone
when something happens, questionable competence of support personnel,
and their tendency to offload a problem to their HW service. "Oh, it's
got to be your line" and then they try to make you pay. I know for sure
that my current email receiving issues are not telco HW related but it
sure would be nice to tell them "Hey, I measured these dBV levels for
the pilot tones so it can't be".
