Abstract
A selective ring response device for a telecommunication line comprises: a ring tone detector circuit for detecting a special ring tone different from a standard ring tone, the ring tone detector circuit coupled to the communication line; an interface circuit capable of placing the communication line in an off-hook status and capable of selectively applying a switch hook flash signal to the communication line, the interface circuit coupled to the communication line; and a control circuit coupled to the ring tone detector circuit and the interface circuit, wherein the interface circuit places the communication line in the off-hook status, and at the user's request applies the flash hook signal to the communication line in response to the ring tone detector circuit detecting the special ring tone.
