BladeWare FITS

Commetrex has led the industry effort for T.38 interoperability since January 2002, when it launched the T.38 Interoperability Test Lab, setting the benchmark standards for FoIP interoperability. Since then, nearly every test-equipment vendor in the industry has licensed the core technologies in BladeWare as the basis for their FoIP test-equipment products. Now, NetGen Communications has introduced the BladeWare Fax Interop Test Suite (FITS) to allow the OEM to perform similar testing in house. BladeWare FITS is a ready-to-test system based on the BladeWare stand-alone IP-based media server that provides the developer with a T.38 and G.711 pass-through interoperability testing facility.

FITS uses BladeWare to place and accept SIP calls and to send-receive faxes for testing purposes. BladeWare’s fax capability is based on Commetrex’ TerminatingT38, which is the same technology that became the industry’s T.38 reference standard through its use in the T.38 Interop Lab. TerminatingT38, which Commetrex invented in 2000, is the integration of Commetrex’ T.38 relay and T.30 protocol engines.

BladeWare may be used to test PSTN-IP gateways and fax-capable media servers. BladeWare’s interface with the balance of the test environment is the IP connection. This means that it can directly test an IP-fax-capable media server without additional network elements being required. It can also connect with the IP side of a gateway under test that has a connection with a fax terminal, fax board, or a TDM loop back to a PSTN-IP gateway, with the IP connected back to BladeWare for a complete loop-back. BladeWare FITS may also be used to test IP-based networks for T.38 and G.711 pass-through robustness.
