VDSL2 17a or VDSL2 35b ?
« on: June 25, 2021, 01:17:18 PM »

Dear All,

Hope my very first post finds you very well!

My provider gives me the option - for an extra charge - to upgrage to the 35b super vectoring profile.
Currently, my DSL connection utilizes the 17a profile and my downstream connection speed is aproxamately 70 Mbps.

Do you believe, based on the attached spectrum of my line, that 35b could give an actual boost to the connection speed?

I am noticing that near the 17Mhz frequencies the singal is already week... Could the 35b profile, which will extend the usable frequency range up to the 35Mhz frequency, provide any usable frequencies? Is it true that the 35b profile increases the line voltage? Will this voltage increase provide a stronger signal up to the 35Mhz frequncy?

Eagerly awaiting your thoughs,

PS: The Distance of my modem / router (Fritz 7590) from the DLSAM is approxiamtely 500m.

It will provide a noticeable benefit imo.
