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 CPE 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.
