Number Five Crossbar Switching System
Imagine you have a bunch of phones, and you want to be able to connect any two phones together. The number five crossbar switching system is a fancy way to do that.
Here's how it works:
1. First, let's say someone picks up the phone and dials a number. The number is sent to the crossbar switching system.
2. The system then uses a bunch of little switches that look kind of like see-saws to connect the right wires together.
3. If someone from another phone dials the same number, the system knows to connect those two phones together.
4. But what if someone else wants to call the first person while they're already on the phone? The system can also connect a third phone to the conversation.
5. When everyone is done talking, the little switches move back to their original positions so they're ready for the next call.
Overall, the number five crossbar switching system is a really cool way to connect lots of phones in a big city. It was used for many years before newer, fancier technology came along.
