Patent number: 7539758Abstract: A communication system includes a local unit that has a lower data link layer and a session layer running a data pass-through application and a user interface. The data pass-through application lets the data link layer in the local unit pass data through to a remote unit. The remote unit has a lower data link layer and a session layer executing a user interface. When the data link layer detects that the session layer is unstable and/or locked up, the data link layer transmits a disconnect request to the local unit's data link layer. All further user data sent to the local unit's data link layer is routed to the local unit's user interface.Type: GrantFiled: May 16, 2002Date of Patent: May 26, 2009Assignee: ADC DSL Systems, Inc.Inventor: David J.

Patent number: 7299285Abstract: A system uses a resource locking token to allow various processes to have exclusive access to a system resource. The process that receives the token then requests that a local database be updated/synchronized with a master database. The process continues checking the synchronization status every time it gets the token. When the process receives the token and the synchronization is complete, the local database is accessed and the data is used in accessing the system resource. The token is then returned to the system.Type: GrantFiled: May 15, 2002Date of Patent: November 20, 2007Assignee: ADC DSL Systems, Inc.Inventor: David J. Kasper, II
