STOKEN RING

Token Ring is a local area network in ring topology promoted by IBM which is based on the standard IEEE 802.5. It allows data rates from 4 to 16 Mbit/s. Its ring connection is achieved by cabling the terminals in star where in the center a concentrator device (MAU) is installed.

Depending on the distance, the type of installation and the location of the terminals, the local area network is protected by installing protectors at the concentrator device, or at the terminals, or on all network elements.
