The SCS Network: Wiring

Floor, per-building ethernets delivered to office by multi-port hub stacks in floor wiring closets, hubs fed from ethernet port on backbone with UTP/coax/fiber

IBM Type-2 cabling system connects patch panels in floor wiring closet to data outlets found in each office on floor

Connections made between one hub port and closet patch panel and office outlet/media using impedance-matching devices/baluns

10BASE-2 (thinwire), 10BASE-T, Tokenring, LocalTalk distributed this way

Still some 10BASE-5 (COAX) ethernet in use in WeH

Floor ethernets are SHARED ethernet, hubs are only repeaters, but using wiring, provide "star" topology
