MultiDSLA

Connect and manage multiple DSLA, ISDN and VoIP test nodes from a single PC - a scalable solution for Enterprises, Network Equipment Developers, Integrators and Operators (PSTN, Wireless, VoIP). MultiDSLA systems measure network narrowband and wideband performance as well as conference bridge, IVR and PBX equipments. Enterprise end-users or Operator's customers can check their own VoIP connectivity with a downloadable Virtual Node.

DSLA II - Digital Speech Level Analyser

The Digital Speech Level Analyser II is a high quality end to end speech performance measuring system which can connect to analogue 2-wire, 4-wire and handset ports, as well as ISDN and VoIP. This versatile instrument is essential equipment for developers and operators of voice activated devices, codecs, echo-cancellers, transcoders, VoIP gateways, telephones and networks. It generates any speech test signal and evaluates the resultant signal after it has been processed by a network or network element, even those subject to packet loss or variations in delay. The system predicts narrowband and wideband speech quality scores (MOS) and measures the characteristics of the speech channel.

VoIP Monitor Professional

A cost-effective software tool for non-intrusive assessment of speech quality and measurement of RTP/RTCP traffic parameters in VoIP networks. VoIP RTP packets arriving at a media gateway are subject to timing variations as well as loss and mis-sequencing. VoIP Monitor analyses the RTP traffic to produce real-time useful statistical data and predictions of speech quality across a single call or many calls.

Speech Performance Analyser

The Speech Performance Analyser provides almost all the measurements that DSLA makes in a convenient package for codec developers and software engineers. The SPA dynamic linked library can be called from a user application program with reference and degraded filenames. The SPA returns key numerical data to the application program along with a wealth of detailed graphical information file if desired.
