The TE Connectivity 5557314-2 is a 6-position, 4-conductor (6p4c) modular jack — the footprint for RJ11 and RJ14 telephone-style plugs, not the wider 8p8c RJ45.
The 6p4c contact arrangement means this jack accepts 6-position modular plugs wired for 4 conductors — standard for single-line RJ14 or dual-line RJ11 handsets. The right-angle SMT orientation places the jack body flush against the board edge, which saves z-height inside a 1U enclosure but requires the cable exit to be parallel to the PCB.
