Applications

Ungermann-Bass hubs were used in legacy Ethernet networks of the 1990s for workgroup connectivity and network segmentation. The STM24 was deployed in corporate and institutional environments where distributed hub architecture was standard before switched networking became prevalent. The three-segment design allowed traffic isolation and network expansion within structured cabling systems.
