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 port on this device contains one wire-pair, an inner pair on pins
3 and 4. This wire-pair carries the digital data.
