PLEX and AXE system




PLEX (Programming Language for EXchanges) is a special-purpose, pseudo-parallel and event-driven real-time programming language. Dedicated for AXE telephone exchanges, it was developed by Göran Hemdahl at Ericsson. Originally designed in the 1970s, it has been continuously evolving since then. The language has two variants: Plex-C used for AXE Central Processors (CP) and Plex-M used for Extension Module Regional Processors (EMRP).
