MultiDSLA combines with the VoLTE Anritsu MD8475A Signalling Tester to provide bi-directional speech quality measurements.
The MultiDSLA system uses DSLAII to connect to the User Equipment (Smartphone) in the analogue domain. A Scalable VN is used to generate and record speech in the IP domain. Scalable VN sets up a call to the UE using SIP. Measurements of speech quality using ITU-T Rec. P.863 POLQA or P.862 PESQ, delay, speech level and many other parameters are made.
The VoLTE Anritsu MD8475A Signalling Tester supports a SIP server and IMS Services making it easy for Scalable VN to establish the call to the UE.
The combination of MultiDSLA and MD8475A make a great tool for handset manufacturers and network operators ensuring the next generation of products and services meet customer expectations.
