  Token Ring Distribution Box (Multistation Access Unit)
  The IBM 8228 Multistation Access Unit is a simple 8-lobe wiring concentrator that can be installed in a rack in a wiring closet. Each 8228 allows up to eight attaching devices to have access to a ring. The 8228 does not require an external power source for operation.

The IBM 8228 is an unintelligent, unpowered Token-Ring multistation access unit. It can attach up to eight devices in a 4-Mbps or 16-Mbps Token-Ring network. Using IBM Cabling System ICS Connectors, cables from the workstations or devices are simply plugged into the unit. The 8228 supports STP cabling as well as UTP cabling when used with appropriate connectors or filters.

8228s can be linked together to form rings that are larger than eight lobes by attaching the RO receptacle of one 8228 to the RI receptacle of another 8228. The 8228 uses IBM type 1 or type 2 STP cabling and connectors.
