OT: phone line 2 ethernet converters

[Gustavo Rios <rios_(_dot_)_gustavo_(_at_)_gmail_(_dot_)_com>]

Dear friends,

sorry for being off-topic, i am able to rent a pair of twist line (a
circuit) between my home and and friends one. I wonder if there exist
and ethernet extender device that could connect an ethernet cable to a
phone line. It would do no special work, just a raw connection between
2 types of layer, i.e, take "bits" from one end and put it into the
another and vice-versa.

BTW: i am no engineer (CS Bachelor), so sorry if it sounds too stupid.

Does that exists ?

PS: yes, i am a user of OBSD and i am using this list cause i know no
other best suited for this message, if possible, point me one possible
"right" mailing list for such subject.
