Lobe Attachment Module
In token ring networks, A Lobe Attachment Module is a box with multiple interfaces to which new network nodes can be attached. A LAM may have interfaces up to 20 lobes. Functionally a LAM is like a multi-station access unit, but with a larger capacity: 20 nodes as opposed to 8 nodes for MAU. The LAM interface may use either IBM connectors or 8P8C modular plugs.
LAMs can be daisy chained and connected to a HUB, known as Controlled Access Unit in token ring terminology. Each CAU can handle up to 4 LAMs for a total of 80 lobes.
