Strowger PABX Startup
Witness the re-commissioning a 46 year old electromechanical private branch exchange. The Ericsson 10+50 Strowger PABX supports 50 extensions and 10 trunk circuits, and a number of surprisingly complex features for a Strowger PABX. I've had this unit in storage for over a decade, this is the first time it's been powered up in probably 3 or 4 years.
