Modem cables
The cabling for modem operation is typically very simple. The
modular connection uses the two inner wires of the RJ-11 jack for
“tip” and “ring.”
Connect one end of the cable to the terminal and plug the other
end into your RJ-11 type modular telephone wall jack.
If a modular wall jack is not available, obtain an adaptor from
your local telephone company.
