Applications

IMA (inverse multiplexing o ATM)

Does your UMS network include IMA technology to transport AM trac over abundle o 1 or E1 cables? Looking at individual E1/1 links, or multiple individuallinks simultaneously is meaningless without the higher-level IMA technology view.JDSUs IMA add-in soware works in conjunction with Signaling Analyzer to ana-lyze networks incorporating IMA technology. Te product allows Signaling Analyzersoware to acquire IMA measurements and present this inormation in the SignalingAnalyzer environment. Te soware can analyze data rom one IMA group at a time.


With the Signaling Analyzer demux and channelization solution, the SignalingAnalyzer soware can extract and analyze up to our ports o SM-1/OC-3 tributaryanalysis or a simultaneous total o 336 V1.5/VC11 1s or 252 V2/VC12 E1s orAM. Demux and channelization or AM and HDLC is included.

Te solution needs just a raction o the number o hardware probes and associated

cables that traditional approaches require. JDSUs solution achieves an attractive portcost by signicantly reducing the number o required hardware probes. With JDSUsarchitecture, more E1/1 links can be easily added. A single DNA can support up to336 1s or 252 E1s.

Signaling Analyzer XML API

Te Signaling Analyzer API provides an XML-based application programminginterace to all major unctions and applications within the Signaling Analyzer. BuildSignaling Analyzer into an automated test or regression test system. Te extensive,ull-eatured API enables test automation with accessibility o virtually any majorunction o the soware to get access to test results with minimal manual engineeringeort.

See Figure 15.

UMTS 3GPP support and UTRAN optimization

Are you implementing R5 or R6 capabilities in your networks? JDSU invests to keep

Signaling Analyzer current with the latest technology waves. JDSU engineers regu-larly incorporate 3GPP updates to support the most current updates o R99, R4, R5,and R6. All supported Signaling Analyzer unctions such as call trace, graphical andtabular statistics, and detailed ltering capability is supported or 3GPP Release 5- andRelease 6-based HSPA URAN systems.

Are you moving to an IP based URAN? Will you need to monitor a mix o AM andIP based URAN interaces? All UMS analysis eatures can be applied regardless othe transport type utilized.

In addition to timely 3GPP release support, JDSU has worked with a number o lead-ing NEMs to pioneer the industrys rst HSDPA and HSUPA optimization tools. Areresources eciently allocated and correctly utilized by RNC and NodeB? Is the RANdelivering services eciently? Many leading-edge NEMs have resolved signicantow control optimization issues that would have been extremely dicult to nd andisolate without the HSDPA and HSUPA optimization tools.
