Abstract
An integrated access device (IAD) protects overcurrent of a DAA chipset. The IAD periodically detects an on-hook/off-hook state of the DAA chipset, and periodically monitors an OPD state of the DAA chipset upon the condition that the on-hook/off-hook state of the DAA chipset is detected in off-hook state at least twice. The IAD further sets the on-hook/off-hook state of the DAA chipset as on-hook to avoid damage to the DAA chipset caused by overcurrent upon the condition that the OPD state of the DAA chipset indicates the DAA chipset is overcurrent.
