Patent ID: 7508929

Claim:
In a telephone system having at least one telephone and at least one telephone line, and a circuit connected thereto which provides a busy signal in said telephone line when a telephone is in an “in use” mode, a simulation means connected to said line to simulate said “in use” mode independently of any incoming telephone signal, comprising: a. switch means in said circuit, switchable between an open circuit position and a closed circuit position; b. relay means connected to said switch means to switch said switch means between said positions; c. controller means connected to said relay means to cause said relay means to switch said switch means as aforesaid; and d. time set means connected to said controller means to set time intervals that the controller means causes the relay means to switch said switch means as aforesaid independently of any incoming telephone signal wherein the time set means provides the following functions: a “Set Timer On” function to repeatedly control the start of the simulated “in use” mode in minutes and hours; a “Set Timer Off” function to repeatedly control the end of the simulated “in use” mode in minutes and hours; a repeat function whereby once set, the two functions set out in 3.a and 3.b above remain as set until they are changed; a clock and a “Time Set” function to set said clock to the time of day in minutes and hours; a “Reset line” function for releasing the prior “set” times, whereby the telephone is brought back to its normal operating mode; while, at the same time saving the repeatable functions in place for the next day; and an “On/Off” function for controlling the operation of the simulation means.
