System and method of testing open systems interconnection (OSI) layers in telecommunication networks

A development test system for testing Open Systems Interconnection (OSI) layers 3 through 7 of a plurality of communications protocols utilized between nodes in a telecommunications network, said system comprising:

• a protocol simulator that simulates OSI layers 3 through 7 of said plurality of communications protocols;
• a local area network (LAN) connected to said protocol simulator with a plurality of Internet socket interfaces, each of said plurality of Internet socket interfaces replacing OSI layers 1 and 2 of a different one of said plurality of simulated communications protocols;
• and
• a target telecommunication node connected to said LAN with a target node Internet socket interface, and performing operations with blocks of application software, said operations validating the use of each of said plurality of communications protocols with said target telecommunication node.

• a protocol simulator that simulates OSI layers 3 through 7 of a plurality of communications protocols;
• a local area network (LAN) connected to said protocol simulator with a first Internet socket interface, said first Interact socket interface replacing OSI layers 1 and 2 of said plurality of simulated communications protocols;
• a protocol interface gateway connected to said LAN with a second Internet socket interface;
• and
• an emulator that emulates a target telecommunication node, said emulator connected to said protocol interface gateway and performing operations with blocks of application software utilized in said target telecommunication node, said operations validating the use of each of said plurality of communications protocols with said target telecommunication node.
