Line cards in the Fujitsu PBX
These circuit boards were line cards in the private branch exchange (PBX) system that controlled the hotel's telephone lines. Each card controlled four extensions. The phones in the hotel were almost exclusively rotary dial even into the year 2000, making this a particularly unusual example of a 200+ extension telephone system.
