Abstract: The distributed architecture switch of the invention provides a scalable, flexible switching device to route telephone calls and other data (e.g., frame relay, ISDN) over an asynchronous transfer mode (ATM) network. The switch includes multiple service modules that can be geographically disparate and function as a single switching device. The multiple service modules are coupled to a system controller that controls the service modules and passes messages between the service modules.
Abstract: The mechanism for inserting, extracting, sensing and locking a printed circuit board assembly (PCBA) in an electronic system provides both easier use and a longer service life for the PCBA as compared to a mechanism having two locking handles. Insertion, extraction, sensing and locking are simplified because a single handle can be used rather than two handles. The service life of the associated PCBA is extended because the forces applied to the PCBA are synchronous and applied more evenly than a PCBA having two handles, which reduces bending and other forces that can cause component failure.
