Standard telephone RJ-11 connectors and cabling can be found in several
common wiring patterns. These six-pin connectors can accommodate up to
three wire-pairs (three telephone lines), but usually only one or two pairs
of conductor pins and wires are implemented.
The RJ-11 ports on the side of the Gateway contain two wire-pairs, an
inner pair (pins 3 and 4) and outer pair (pins 2 and 5). On the LINE port,
the inner wire-pair carries both voice and digital data. On the PHONE port,
the inner wire-pair carries voice only.
The outer wire-pair is only connected if there is a second telephone line,
and carries voice only.
