An arrangement in a token ring line concentrator for providing appropriate connections to a cable includes a connector adaptor (30, 60) having a printed circuit board (34, 64) on which selected contact members (36, 38; 66, 68) are left either unconnected or shorted together to identify the particular type of adaptor, thus identifying the particular type of cable plugged into the adaptor. The port to which the adapter is inserted includes switchable connections controlled by the selective energization of a relay coil (138). The coil (138) is energized when an open connection between the selected contact members is identified.
