Lobe Attachment Module

In token ring 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 (RJ-45) modular plugs.
