The STT Multi-Service Analyzer is an all-in-one portable test solution for today’s and tomorrow’s networks. Whether the network is mobile, PSTN or VoIP, the STT MSA with its 4 Analog, 8 T1/E1, 4 LAN and 2 OC3/STM-1 physical ports is the best tool addressing troubleshooting needs during the installation and maintenance.

o Flexible and scalable platform
o Protocol Analysis and Testing
o Protocol Monitoring for VoIP, Mobile/cellular and PSTN networks o Protocol Simulation for VoIP, ISDN, SS7, Analog
o Quality of Service Testing & Measurement (Jitter, Packet Loss, Delay) for VoIP
o Voice Quality Testing and MOS generation by using PSQM, PESQ algorithms for SS7 ISUP, ISDN, Analog and VoIP
o Graphical scripting tool for SIP & MGCP/NCS simulation & protocol testing
o Service Testing for VoIP, ISDN, SS7, Analog with Graphical scripting tool

Flexible and scalable platform
o PC based. Windows XP support
o A part of the STT platform: supporting other technologies such as Fiber, DWDM, Ethernet, SONET, SDH
o Supports various physical interfaces (E1/T1, LAN, Analog, STM-1/OC3), necessary in a Next Generation voice and cellular environments
o Local storage allowing to record data and traces to do further analysis later
o Remote access

Protocol Analysis and Testing
o 2 simultaneous tests, up to 4 protocols per test
o Multi interface tests
o Advanced call tracing, decode, statistics, filtering, search and trigger for many protocols
o Call Detail Record (CDR), making the troubleshooting easier
o "CDR to Signaling Frames" mapping
o Call Flow diagram for the messages of monitored or simulated call
o Correlation between SS7 ISUP and MCGP/ASPEN calls
