  • FAULT TOLERANT ATM-BASED DISTRIBUTED VIRTUAL TANDEM SWITCHING SYSTEM AND METHOD
    Publication number: 20070286200
    Abstract: A System and method for reducing and surviving failures in a voice trunking over ATM (VTOA) environment includes a CS-IWF complex having a plurality of interconnected CS-IWF units, each unit having a plurality of processors. An end office building may also be provided for interaction with the VTOA system. The end office building includes multiple T-IWFs, and a switch that distributes calls among the T-IWFs in a load sharing manner. Each T-IWF has a plurality of processors and is part of the VTOA system. A switch management system is also provided in the VTOA system. In order to reduce and survive failures, the switch management system includes a plurality of switch management system units. At least one of the switch management system units is a backup unit for a primary switch management system unit. Each switch management system unit provides application redundancy within itself.

  • Fault tolerant virtual tandem switch
    Patent number: 7227837
    Abstract: A system and method for reducing and surviving failures in a voice trunking over ATM (VTOA) environment includes an ATM network having a plurality of interconnected ATM switches. The VTOA system also includes a CS-IWF complex having a plurality of interconnected CS-IWF units, each unit having a plurality of processors. An end office building may also be provided for interaction with the VTOA system. The end office building includes multiple T-IWFs, and a switch that distributes calls among the T-IWFs in a load sharing manner. Each T-IWF has a plurality of processors and is part of the VTOA system. A switch management system is also provided in the VTOA system. In order to reduce and survive failures, the switch management system includes a plurality of switch management system units. At least one of the switch management system units is a backup unit for at least one primary switch management system unit. Each switch management system unit provides application redundancy within itself.
