Number Five Crossbar Switching System
The Number Five Crossbar Switching System or 5XB switch, designed by Bell Labs and made by Western Electric, was in use in Bell System telephone exchanges from 1948 to the early 1990s. Its principal use was as a Class 5 telephone switch, though variants were used as combined class 4/5 in rural areas and as a TWX switch. 5XB was originally intended to bring the benefits of crossbar switching to small towns with only a few thousand telephone lines. The earlier 1XB urban crossbar was impractically expensive in small installations, and had difficulties handling large trunk groups. 5XB was converted to wire spring relays in the 1950s and otherwise upgraded in the 1960s to serve exchanges with tens of thousands of lines. The final 5A Crossbar variant in the early 1970s returned to its roots, being available only in sizes of 960 and 1920 lines, and generally delivered on one pallet rather than assembled on site as usual for larger exchanges.
