Patent GB-2138653-A (GB)
Title: Telephone Ring Detector System
Inventor: LYLE STEPHEN VINCENT
IPC: H04M1/654
Filed: 1984-02-22
Abstract: A telephone ring detector system e.g. for a telephone answering unit, responds only to ring signals on the telephone line, and is unresponsive to dialing pulses which would otherwise cause a spurious activation of the telephone answering unit. The system of the invention differentiates the ring signals from dialing pulses by providing an output in response to an incoming signal only when the telephone is in the "on-hook" condition. This assures that the signal detected on the telephone line is not a series of dialing pulses, since the dialing pulses occur only when the telephone line is in the "off-hook" condition. The system of the invention is effectively direct-current isolated from the telephone line; has the capability of sensing positive or negative voltage deviations when the receiver is taken off the hook, so as to be effective with all types of telephone systems; and has the added capability of sensing true ring signals outside the normal frequency range which would be rejected by many prior art systems. <IMAGE>
