(Later Bosch Telecom) These are Mobile Telephone Switching Office Cellular switches (CX evolved from the "Automanual" system designed by Edward Clements: "Clement eXchange" or "Community eXchange") The McBerty design used an early "wire spring relay" and welded piano wire interconnections rather than complex wire multiples.

The system never achieved the reputation of the CX product due to problems with poor contact pressure in the interconnection relays.

Despite its much lower cost of production and installation, the level of maintenance required to keep these systems on good order doomed this variation of the CX design.
