Voice over Internet Protocol (VoIP) continues to enjoy considerable commercial acceptance. A recent analysis of North American Residential VoIP Markets from Frost & Sullivan, indicated that market revenue is expected to reach over $4 billion in 2010. Since VoIP solutions are replacing switched circuit connections, they must replicate all switched circuit capabilities and that requires compatibility with fax transmissions and the millions of fax machines installed around the world.
T.38 is an ITU standard for sending FAX across IP networks in real time as an Internet replacement for the PSTN. Many corporations are creating data collection and management systems using fax technology.
With QualityLogic’s DataProbe™ T30-T38 Analyzer, you can record, display and compare T.30 messages and T.38 packet contents as they appear across T.38 gateways during facsimile calls. DataProbe T30-T38 Analyzer monitors fax calls at both analog and IP levels, compares the details of the T.30 to T.38 and back transform, and provides expert analysis of the results with error detection and tracking.
You can create an end-to-end test system with QualityLogic’s FaxLab® interoperability test tool and multiple ChannelTrap hardware devices to identify T.30 fax message degradation caused by the network transport, and use DataProbe to monitor the T.38 exchanges between the gateways.
