A system and method for managing faults in a data transmission system that includes a data path for transmitting signals containing data, and a plurality of application cards located along the data path for processing the signals. The method includes the steps of detecting the occurrence of a fault of a particular type at one of a plurality of points along the data transmission path; in response, the application card generating a fault report for the purpose of identifying the cause of the detected fault; and, preventing the generation by the application card of subsequent fault reports relating to that particular type of fault until receiving a signal indicating that fault report generation may be reenabled. In the fault management system, the data transmission system also includes at least one unit controller for controlling the application cards, and at least one system manager for controlling the at least one unit controller. The system further includes application card software residing on the plurality of application cards, unit controller software residing on the at least one unit controller, and system manager software residing on the at least one system manager. The application card software is capable of generating a first fault report in response to detecting that a first fault of a particular type has occurred in the data transmission system, and suppressing the generation of subsequent fault reports relating to that particular type of fault until receiving a signal indicating that fault report generation may be reenabled.

A method for managing memory in an object oriented program that is capable of using a plurality of fixed pool classes and a plurality of objects belonging to those fixed pool classes. A plurality of memory pools each having a predetermined fixed size are constructed, with each of the plurality of fixed pool classes being associated with one of the plurality of memory pools. New objects belonging to a selected one of the fixed pool classes are instantiated, with the instantiation step including the step of allocating memory for the new object from the associated memory pool. A system for managing memory in an object oriented program operating on a computer system is also provided that includes a memory pool class and a plurality of subclasses of that memory pool class, where the object oriented program is capable of using and instantiating objects belonging to the subclasses. The system also includes a plurality of memory pools each having a predetermined fixed size, where each of the plurality of subclasses is associated with one of the plurality of memory pools, and wherein memory for objects of a selected subclass that are instantiated by the object oriented program is allocated from the associated memory pool.

A method and system for summarizing object interactions in an object-oriented software program is disclosed. A plurality of tabular inputs containing information about the object interactions in a software system are input into a computer system. The system then determines object information and interaction information from the input information and generates an object summary from the object information and interaction information. The object summary may comprise an object summary matrix indicating instances of interaction between the objects of the software program and a plurality of message summaries that indicate messages sent from and sent to a particular object of the software program.

A method of collecting PM data in a controller acquired from a plurality of sources of PM data during a monitoring interval, including the steps of demarcating, at each source of PM data, the monitoring interval, assigning, at each source of PM data, an identity to the monitoring interval, packaging at each source of PM data, the PM data from the monitoring interval, transmitting an armed and ready message from each source of PM data to the controller, waiting, at each source of PM data, for a request from the controller for a bulk transfer of the PM data, sending the bulk transfer from each source of PM data, responsive to receipt of the request, to the controller, and resetting, at each source of PM data, a system timer for a next monitoring interval.

An automatic switching system and method is provided for switching between paths in a telecommunications switching system. A first circuit in each path receives substantially identical telecommunications signals containing telecommunications data and transmits substantially identical digital signals containing the telecommunications data. The first circuit is capable of detecting whether errors have occurred during transmission of the telecommunications signals, and of inserting into the digital signals an error indicator if a transmission error has been detected. At least one second circuit in each path accepts the digital signals from the first circuit in a selected path, and is capable of detecting whether the error indicator is present, and automatically switching to accept the digital signals from the first circuit in the non-selected path in response to detection of the error indicator.

An integrated multi-rate cross-connect system (10) includes a broadband subsystem (14) for processing optical and electrical telecommunication network signals. A wideband subsystem (16) processes wideband level electrical telecommunication signals from the network, from the broadband subsystem (14), and from a narrowband subsystem (18). The narrowband subsystem (18) processes narrowband level electrical telecommunication signals from the network and the wideband subsystem (16). An administration subsystem (12) provides centralized control and synchronization to the broadband subsystem (14), the wideband subsystem (16), and the narrowband subsystem (18). The wideband subsystem (16) is coupled to the broadband subsystem (14) and the narrowband subsystem (18) by internal transmission links (30) to allow for remote distribution of each subsystem. Each subsystem operates within its own timing island synchronized to a reference timing signal to facilitate component distribution.
