Abstract
A self-initializing communication system is described which automatically itializes circuit boards of the system using predetermined operating parameters when the system is initially powered-up or reset. The system is arranged to initialize circuit boards inserted in any order in any board slots of the system equipment housing. A malfunctioning circuit board can be replaced while the system is operating and the replacement circuit board is automatically initialized by the system using the stored operating parameters from the malfunctioning circuit board.
