This read-write enumerated value initiates a segment-level continuity test toward the customer premises equipment (CPE) side of the connection by sending an OAM segment loopback cell that the CPE is expected to loop back, defaulting to notest and automatically reverting to notest once the test completes. Admins use this specifically to test the segment between the switch and the CPE, complementing the network-side test performed by ausmChanTestType, useful for isolating whether a connectivity problem lies on the customer-facing side rather than the network core side. For example, an admin suspecting a CPE-side cabling or configuration issue would set ausmChanTestTypeCPESide to testconseg and watch ausmChanTestStateCPESide for a pass/fail result specific to that customer-facing segment.
