Telephone disable feature

Abstract

Apparatus and process for allowing a user to selectively disable all or a portion of the manual controls, e.g., the keypad and/or other buttons (including switches, keys, on-hook button, and/or other buttons) of customer premises equipment. The customer premises equipment includes a button disabling module which allows subsequent control signals relating to the particular keys or buttons which have been disabled to be essentially ignored. Thus, for instance, if an on-hook button is inadvertently depressed while the on-hook button has been disabled by the button disabling module, the telephone line interface of the telephone will not signal the termination of the telephone call to the central office. The manual controls of the customer premises equipment can be disabled by the user in any of a number of different ways. For instance, a dedicated button at either the base unit or the handset of a telephone may be provided, or a sequence or simultaneous combination of alphanumeric keys and/or other buttons may be sensed. The disabled button(s) can be re-enabled either manually by the user, or automatically, e.g., after hanging up the telephone. A timer can be included to automatically re-enable any disabled manual controls (i.e., buttons) if the user failed to manually re-enable disabled buttons before terminating the previous telephone call.
