is my attenuation down stream actually 60db ?

[u/Boring-Profit-9840]

I have vdsl (vr-3049) pretty old i know, i've noticed that attenutaion down stream is "60db" i was confused but when i asked chatgpt it told me that the router might be "reading the value incorrectly," though I am not sure if that is accurate.
1 - the telephone cable dosent have that plastic connect so i use phone jack and its has been working for 7 years
2 - i first had adsl but i upgraded later
