Network Switching Hub NZ.B

Netzknotenpunkt NZ.B

NZ.B was one of four type 617 telephone switching posts established along the Fortress telephone network, and this example at Rouette de Courtures was built above ground with a pitched roof and painted windows, like the example NZ.E. Today, it has a modern extension but is visible from the road, and gives a good idea of the dimensions of the type.
