Abstract
An improved dialing system, basically powered through the line, that provides automatic dialing of stored, frequently used numbers and the last number dialed. Self-test capabilities are provided to enable and test all the stored number memory locations automatically. Outgoing call restrictions are provided with a programmable code to bypass the call restriction. The system automatically converts push button dialing to rotary outpulsing, or generates dual tone multi-frequency dialing signals.
