How does a switchboard work to transfer phone calls?

In: Technology

Back in the old days that was the only way to route calls from one place to another, by physically moving and connecting wires from one plug to another. As we advanced telephone technology we developed systems to switch us automatically without manually moving plugs, and now to a point where you can travel hundreds of mile from home and still make/receive calls with no problems, since it’s wireless.

It works a lot like those matching worksheets you used to do in elementary school. Picture incoming lines 1-8 on the left and outgoing lines 9-15 on the right. Line 3 calls in and says please transfer me to line 14, the switchboard connects 3 to 14, and that’s that.
