The charger cord for my AT&T's DSL modem (2Wire 2701HG-B) died, so I
purchased a new one online at Amazon.com.

The only difference between the original cord and the new one is that
the old one output was 5.1V @ 2.2A, whereas the new one is 5V @ 2A.

The modem seems to work ok with the new cord. But, because I am not a
techie, I don't know if such a difference in V and A could damage my
DSL modem in the long run.

What do the experts have to say?
