RJ-11 Ports
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.
