Now, you can get a tool that 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. QualityLogic’s DataProbe T30-T38 Analyzer is an analysis and reporting tool that records, displays and compares T.30 messages and T.38 packet contents as they appear across T.38 gateways during facsimile calls.

This multi-node communication channel test tool helps R&D, QA and field service personnel isolate facsimile operational problems quickly with passive monitoring and protocol analysis capabilities.

With the FaxSend optional utility, the DataProbe T30-T38 Analyzer can generate T.30 traffic with known characteristics and varying loads to test fax systems. The product’s distributed hardware architecture simplifies the task of performing end-to-end testing of facsimile communication systems, and quickly identifies problems caused by the communications network infrastructure.

The DataProbe T30-T38 Analyzer is a software application that runs on any Windows® 2000 or Windows XP workstation. Traffic monitoring is performed by self-contained DataTraps and a Network Interface Card (NIC) installed in the DataProbe host computer. The DataTraps monitor T.30 analog facsimile traffic for detailed analysis. The NIC detects and records SIP, T.38 and associated RTP IP traffic. DataTraps can connect between a fax or telephony gateway unit and an analog interface to the public telephone network or analog switch to monitor and report the communications between the originating and answering fax units.

End-to-End Transmissions

Facsimile calls can be corrupted or degraded as they pass through complex digital and/or analog networks. This can occur as the result of timing delays, dropped packets, or other network anomalies.

The DataProbe T30-T38 Analyzer with the optional FaxSend utility can be used to control multiple DataTraps and ChannelTraps to create an end-to-end test system that plays both the originating and answering terminals in fax sessions that are sent across such complex networks. The system monitors each call, providing T.30 analysis at all modulations, including V.34 and T.38 analysis including the SIP protocol. This system identifies protocol violations, fax message degradation and timing errors that result from network signal transport.

Isolating Fax Traffic Volume Problems

Communication servers, routers and system software can fail when subjected to high volumes of fax traffic. To isolate this type of failure, DataProbe T30-T38 Analyzer with the optional FaxSend utility controls pairs of ChannelTraps and DataTraps to generate, monitor and capture fax traffic, while a host computer NIC captures FoIP traffic.

DataTrap/ChannelTrap units can be distributed in a variety of locations to realistically monitor and simulate traffic patterns.

Specifications

T.30 Facsimile Capabilities

• Support for 2003 ITU-T T.30 Recommendation, including passwords, sub-addressing and use of V.34 modulation
• Facsimile call monitoring, up to 33.6 kbps (with a single DataTrap)
• Post-call analysis of T.4, T.6, T.30, T.81 and T.85 conformance
• Send or receive predefined test fax pages via optional FaxSend utility
• HDLC frame analysis and data decoding
• T.30 help system

T.38 IP Capabilities

• Recording and reporting the content and structure of the call-control protocol used during a fax call (SIP, ASN.1)
• Recording T.38 packets (V0 – V2) as they arrive at or are generated by the same gateway during its handling of a fax call (T.38, UDP, RTP, UDPTL – packet redundancy)
• Relating these messages and packets by their contents and times of arrival/generation
• Correlating, analyzing and reporting the content and structure of both T.30 messages and T.38 packets
• Providing error expert analysis of the T.38 content and correlation to T.30 content
  

DataTrap/ChannelTrap Characteristics

• Monitor/capture facsimile calls (DataTrap only)
• Originate and answer facsimile calls (ChannelTrap only)
• External control connection via TCP/IP
• Software configurable
• Browse for DataTraps/ChannelTraps over IP network
