A wiring methodology for attaching office machines to a communications network includes at least one central wiring facility or concentrator with lobe segments emanating or fanning out in a "Star Fashion" configuration to terminal points within offices. A plurality of switch control elements are provided in the concentrator. When activated, each switch control element inserts a lobe segment and attached machines into the communications network. Lobe segments not in use are bypassed (disconnected) within the concentrator. A single station connector (SSC) can be used to increase the number of office machines that may be attached to a single lobe segment. In addition, the SSC may be used to configure a mobile Local Area Network (LAN) System without resorting to permanent wiring schemes.
