Apparatus (34) for communication includes a single one-way link (40), which is physically capable of carrying the communication signals in one direction and incapable of carrying the communication signals in the opposite direction. Ancillary circuitry (48, 50, 52), which is coupled so as to cause the single one-way link to convey both first communication signals from a first station (22) to a second station (32) and second communication signals from the second station to the first station. |
