The VIAVI Signaling Analyzer Real Time (SART) helps services providers realize Return On Investment of your network equipment even faster. With the use of system verification, tactical troubleshooting, monitoring, and optimization, you can ensure success in the operation of complex mobile networks.

　　Highlights:

　　Faster 3G deployment

　　Graphical call visualization engine for rapid troubleshooting and problem isolation.

　　Graphical statistics and Key Performance Indicators (KPIs) designed to run statistics and visualize them graphically for a variety of information elements, focused on higher layer protocols

　　HSDPA support

　　3GPP R5 high-speed downlink packet access (HSDPA) software provides full support for analysis including call trace, statistics, decodes and reassembly of supported release 5 protocols and radio channels including HS-DSCH.

　　Lower cost of ownership

　　Multi-user functionality enables high-performance multi-client analysis by several clients in a single solution. All clients have simultaneous yet fully independent access to measurements flowing through the same hardware platform without impacting or limiting performance of the overall system.

　　Multi-technology -- the ability to trace calls in IMS, SS7, SS7/IP, 2G, 2.5G and 3G mobile networks, which simplifies resolution of the most complex interoperability problems in telephony.

　　Leverage investment

　　Running on the VIAVI DNA, DNA PRO, DNA MX and DNA HD platforms to leverage the same hardware used for data analysis, which enables 7 layer analysis with the same test tool.
