Is it possible to make an Internet connection through two cores of a twisted pair cable using the adsl mechanism?

Question

Telephony

we have a wire - 4 cores utp 5 CCA, length 30 m.
we have a telephone number 044 440-xx-xx.
Two veins are used for telephone connection. Telephone communication works - calls are made in both directions.
I connect an adsl modem to this wire - it (the modem) does not see the connection (does not see the line).
The provider swears that everything is fine with their line.
Tell me what to check?
Thanks for answers! the problem was solved, the provider UkrTelecom first connected to us a line in which the conductors were from different pairs because of this ADSL did not work, but the phone did not care. When the pair was changed - everything worked.

Answer 1

UTP 5 operates at frequencies up to 100MHz, ADSL2+ only uses the range up to 2MHz. So the problem is not the cable.
Is an ADSL splitter installed?
In general, is this modem suitable for this network? ( https://en.wikipedia.org/wiki/Asymmetric_digital_s... )
Is the modem set to the appropriate VC/LLC, VPI/VCI mode?

Answer 2

I don't think the cable is the problem. UTP is thicker than telephone vermicelli.
The problem is either in the modem settings, or in the line itself before UTP. I understand you have UkrTelecom? Anything can be here :)

Answer 3

SHDSL Modems to help you

Answer 4

It is necessary to test the line, perhaps some ordinary dead noodles with a small section go to UTP, and UTP manages to annoy the remaining signal with its section
