Token Ring
Token Ring is a Physical layer, physical and data link layer computer networking technology used to build local area networks. It was introduced by IBM in 1984, and standardized in 1989 as IEEE Standards Association, IEEE 802.5. It uses a sp ...
networks, A Lobe Attachment Module is a box with multiple interfaces to which new network nodes (known as lobes) can be attached. A LAM may have interfaces up to 20 lobes. Functionally a LAM is like a
multi-station access unit (MAU), but with a larger capacity: 20 nodes as opposed to 8 nodes for MAU. The LAM interface may use either IBM connectors or
8P8C
A modular connector is a type of electrical connector for cords and cables of electronic devices and appliances, such as in computer networking, telecommunication equipment, and audio headsets.
Modular connectors were originally developed for ...

modular plugs.
LAMs can be
daisy chained and connected to a HUB, known as Controlled Access Unit (CAU) in Token Ring terminology. Each CAU can handle up to 4 LAMs for a total of 80 lobes.
