Okay forgive my ignorance but....

Q1)Which way to power a telco line? (Note: subsitute "modem" for "telephone")

A) Series?
     --------Battery----------
    | |
Telephone Telephone
    |_________________________|

or

B) Shunt?
     -------------------------
    | | |
Telephone Battery Telephone
    |____________|____________|

Shunt seems more correct but, I think the power source's filtering would
filter out the audio.

Q2)Which lead is NORMALLY the positive (red or green)?
