ABSTRACT:
A method of providing multiple test access for test equipment in a communication network is provided. The method comprises the step of coupling test apparatus to a first communication line via a first communication circuit in the test apparatus wherein the first communication line has a first quantity of equal bandwidth communication pathways that are dedicated for test access. The first communication line is coupled to a first cross connect apparatus. The test apparatus also has a second communication circuit that is coupled to the first communication circuit. The method further comprises the step of utilizing a second communication line having a second quantity of equal bandwidth communication pathways that are dedicated for test access. The second communication line is coupled between the first cross connect apparatus and a second cross connect apparatus. The second quantity is less than the first quantity. The method further comprises the step of controlling the test apparatus to initiate a test procedure wherein the second communication circuit initiates a test of network facilities associated with the second cross connect apparatus.
