    Abstract: A method is provided for verifying repairs in a communication system. In an embodiment, a service network receives a notification from an access network for a completed repair at the access network. The service network comprises a service node and the service network exchanges information with the service node through the access network. The service network retrieves a set of attributes from the notification and determines an identity of the service node using the set of attributes.
