ABSTRACT:
Each station is connected to the token ring network (5) through station and token ring interface units, the latter of which units has a switch (37) for connecting the station to the token ring (5) to transmit signals it receives in digital form either from the token ring or from the station via the associated station interface unit. The data signal received from a station clocked by an oscillator of that station is transcoded in the associated token ring interface unit before it is recoded in its original form under the control of an oscillator (12) common to the stations of the device which is slaved to the oscillator of one of the stations taken as a master station.
