Abstract
A method and apparatus for preventing false alarm activation is provided. According to one embodiment of the invention, a determination (410) is made as to whether an instruction from a controller is a commanded reset, and control of a Subscriber Line Interface Circuit is taken (416) from a voice processor circuit when the instruction is a commanded reset.
Claims9
A method comprising:
- a processor circuit determining whether an instruction from a controller is a commanded reset;
- the processor circuit taking control of a Subscriber Line Interface Circuit from a voice processor circuit when the instruction is a commanded reset;
- the processor circuit executing the commanded reset;
- the processor circuit determining whether the commanded reset has been completed;
- the processor circuit switching control of the Subscriber Line Interface Circuit back to the voice processor after the commanded reset has been completed;
- and
- the processor circuit providing an indication that the Subscriber Line Interface Circuit is no longer being controlled after control of the Subscriber Line Interface Circuit is switched back to the voice processor.

An apparatus comprising:
- a processor circuit that determines whether an instruction from a controller is a commanded reset;
- the processor circuit coupled to the switch control circuit, wherein the processor circuit takes control of a Subscriber Line Interface Circuit from a voice processor circuit when the instruction is a commanded reset;
- wherein the processor circuit switches control of the Subscriber Line Interface Circuit back to the voice processor circuit after the commanded reset has been completed;
- and
- wherein the processor circuit further provides an indication that the Subscriber Line Interface Circuit is no longer being controlled after the control of the Subscriber Line Interface Circuit is switched back to the voice processor.
