Abstract
A wiring concentrator (160)for Fiber Distributed Data Interface (FDDI) networks employs only two PHY modules (182 and 184) for initialization of all attached stations (174, 176, 178, and 180). A bank of switches (204, 206, 208, and 210) initially switches one of the stations into full-duplex communication with one of the PHY modules (182), with which it performs the initialization process. The attached station (174, 176, 178, or 180) is then switched into a loop formed with the other PHY (184), in which loop the station remains in the active state that it reached as a result of the initialization process. The process is then repeated for each attached station. A separate PHY module thus is not required for every attached station.
