If you plug an RJ11 plug into an RJ45 jack, for example, it can potentially damage the equipment. It is very common for connecting computers, networks, telecommunications and factory automations.

It's necessary to use the appropriate standard for equipment compatibility. TB is now the more widely used standard. The difference is in the pin colors, such as pin 1 is white with an orange stripe on the TB, versus white with a green stripe on the A.
