Abstract
A method and architecture for end-to-end surveillance of network systems is disclosed. Comprehensive and rapid fault detection, fault segmentation, and self-testing of network elements are accomplished by utilizing a bit position in message signal units to indicate the surveillance of a particular call. When the surveillance bit is set, message signal units related to the selected call are copied and forwarded to a processing element. The processing element correlates message signal units received to afford fault analysis and fault segmentation of network failures on an end-to-end basis. Additionally, the method and architecture may permit quality control for the network system by utilizing information within the message signal units received by the processing element.
