Application of Common Control to the Overseas AUTOVON Switching System

Separate subsystems provide for registering, translating, and sending telephone address information, and for real-time monitoring and upgrading of line and trunk conditions. The registersender subsystem is time-shared; associated with it are facilities for sending and receiving dial or key addresses. The translator subsystem has a ferrite-core memory, divided into functional sections. The memory subsystem is sequentially accessed by the register-sender, and is either sequentially or randomly accessed by the translator. Six alternate routes are provided per destination, with five levels of precedence and preemption on all trunks busy.
