Patent ID: 7587743

Claim:
A method of interacting between a host device and a point of deployment (POD) module in an open cable diagnosing system, the method comprising: transmitting, by the POD module, a diagnostic request object to the host device through a central processing unit (CPU) interface in accordance with a diagnostic resource; receiving, by the host device, the diagnostic request object through the CPU interface in accordance with the diagnostic resource; performing, by the host device, a specific set of diagnostic functions according to the diagnostic request object; transmitting, by the host device, a diagnostic confirmation object including a diagnostic result of at least one of the performed diagnostic functions to the POD module through the CPU interface in accordance with the diagnostic resource; and receiving, by the POD module, the diagnostic confirmation object, through the CPU interface in accordance with the diagnostic resource, wherein the CPU interface defines a resource layer between an application layer and a session layer, the resource layer including the diagnostic resource, wherein the diagnostic request object includes a plurality of identifiers, each identifier being assigned to one of plural functional units in the host device to be checked for a corresponding diagnostic status, wherein the diagnostic confirmation object includes state information about each of the functional units, wherein the CPU interface defines a data channel between a CPU of the POD module and a CPU of the host device, and wherein the diagnostic request object and the diagnostic confirmation object are exchanged between the host device and the POD module through the data channel.
