Which device is not typically involved in WAN troubleshooting at the customer site?

WAN troubleshooting at the customer site focuses on the equipment that forms the actual WAN path and the wiring that carries the service from the carrier into the customer network. The CSU/DSU terminates the carrier’s circuit and translates it to customer equipment, the demarcation point marks the boundary of responsibility between provider and customer, and the IDF houses the cabling and patching that connect edge devices to the network. A Wireless LAN Controller, meanwhile, manages wireless access points and client traffic over the LAN, not the WAN transport itself, so it isn’t typically involved when diagnosing WAN link faults.
