  • System and method of testing open systems interconnection (OSI) layers in telecommunication networks
    Patent number: 5732213
    Abstract: A development test system and method for testing Open Systems Interconnection (OSI) layers 3 through 7 of a communications protocol utilized between nodes in a telecommunications network. The system comprises a protocol simulator that simulates OSI layers 3 through 7 of the communications protocol, a local area network (LAN) connected to the protocol simulator with a first Internet socket interface which replaces OSI layers 1 and 2 of the simulated communications protocol, and a target telecommunication node connected to the LAN with a second Internet socket interface and performing operations with blocks of application software to validate the use of the communications protocol with the target telecommunication node. A protocol interface gateway (PIG-tool) is connected to the LAN with a third Internet socket interface, and serves as a gateway to a target telecommunication system emulator.
