Wavetek Wandel Goltermann (WWG) has introduced the IMA Monitor and Analysis Application. It is claimed to be the first troubleshooting tool capable of monitoring and analysing Inverse Multiplexing over ATM (IMA) solutions.

IMA, a new standard from the ATM Forum, addresses a problem facing many ATM users: maintaining adequate bandwidth for ATM applications without migrating to expensive T3 and E3 lines. IMA provides higher fault tolerance and bandwidth by multiplexing T1 or E1 lines into a larger logical pipe capable of carrying ATM cell-switched data, voice, and video traffic. Users of this new technology include equipment developers, WAN service providers, and enterprise IT managers.

The IMA Monitor and Analysis Application is a software application that works in conjunction with WWG's portable DominoATM protocol analyser to monitor and analyse IMA data. This easy-to-use application features an intuitive GUI interface to manage the statistics and capture data via DominoATMs. The application simultaneously supports up to eight full-duplex DS1 or E1 circuits that make up an IMA link. This data is then broken down and analysed by Examine, WWG's powerful decode engine, which comes standard as part of the solution and provides decodes for more than 350 protocols.

The IMA Monitor and Analysis Application ensures a focused, and thereby productive, analysis session with features including: extensive pre-capture filtering; complete IMA protocol analysis; measures and compensates for Interlink delay variance.

Wavetek Wandel Goltermann recently became a member of the I3 Alliance, a consortium of companies formed to facilitate the adoption of the ATM Forum IMA standard through interoperability testing. The WWG IMA Monitor and Analysis Application successfully inter operated with WAN access and central office equipment in an independent laboratory test and verification conducted by the IMA Interoperability Initiative (I3) at the Interoperability Laboratory at the University of New Hampshire in the USA.
