How does a Token-Passing Protocol works?
The token-passing protocol relies on a control signal known as the token. A token is a 24-bit packet that circulates throughout the network from NIC to NIC in an orderly fashion.

The existence of only one token eliminates the possibility of signal collisions. This means that only single station can speak at a time.
