This building is flood-wired with structured cabling, each room having a
non-token ring of unshielded untwisted pair, with a number of dual-port Layer
1 hubs and dropleads to each station.  These are fed from a central Layer 1
switch to which is attached the WAN connection.

Ah, it's teatime.  Must go and netboot the kettle.
