Hmmm ... this heavily depends on country and telco i think.
In Germany you get a box called "NTPM" wich is a "Network Terminator
PrimaerMultiplex" ... This box has a 4 Wire output which you only need to
connect to the PM3 Rj45.

G.703 does specify a physical connection ? As i remember it specifies
a framing type on any media in 64KBit/s channels.
