We had the opportunity to take a look at the building at 187 Botersloot, Rotterdam Center. The Rt-C11, Rt-C 12/13, Rt-C 14 and Rt-C 33 Central Exchanges were installed here. When these AGF and ARF plants were replaced, these became Rt-C A, Rt-C F/G, Rt-C D and Rt-C E. Unfortunately, this era is also over and the current plants are dismantled and taken over by servers which are located in the basement.
To give you an idea of the Main Distributor (for the older ones this was the crossboard), some corridors and the Cable Cellar, Joop Nijs has taken some photos. You will find some below.
