Abstract

In buildings, structured cabling is frequently installed, in which outlet boxes are connected in a star-like pattern to a central distribution panel. So that a service-neutral cabling of this kind can be used for the connection of an ISDN bus, a bus panel is added to the distribution panel, and bridge adapters are inserted in the outlet boxes. The bus line is conducted from the bus panel over half of the wires of the cable to the outlet jacks and are returned via the bridge adapters and the other half of the wires of the cable back to the bus panel. In this way, the bus line can be looped in series from one outlet box to the next.
