Abstract
A system and method includes receiving an event, for example, from a frame relay network or from a system log. Whether the event designates a virtual circuit fault in at least one of the local network, the service provider network, or the communications link is determined. When the event designates a virtual circuit fault it is distinguished which of the local network, the service provider network, or the communications link is the source of the fault.
