Team Abacus announces the release of Abacus 5000 - Version 3.1 as GA.

Abacus 5000 IP Telephony Migration Testing System is a fully integrated VoIP/PSTN test solution in a single platform focused on new testing methodologies.

Abacus 5000: IP Telephony MigrationTest system

Spirent's Abacus 5000 is a cost-effective, flexible and scalable IP Telephony test solution, with integrated Analog, TDM and Ethernet interfaces for comprehensive testing of converged or migratory IP Telephony network Elements.

Abacus 5000 test methodology allows users to objectively measure Voice Quality (MOS, PSQM, PSQM+, PESQ, PESQ-LQ, R-factor, J-MOS) under real-world voice stream load generation, test Video Quality. Other test methodologies include distributed, functional, conformance, robustness, decode, performance and interoperability testing.

Abacus 5000 Media Payload formats include tones, compressed and uncompressed voice, Video (H.261 and H.263 encoding), CODEC variants G.711, G.726, G.723.1, G.729A/B encoding and decoding. Mobile NB encoders/decoders GSM-AMR & EVRC, T.30 Fax for Analog and PSTN, T.38 Fax over IP. Echo Measurements and One Way Delay Measurements.

Abacus 5000 supports Triple Play (ACT-5000), Analog (ECG3, XCG3), PCM TDM (PCG3: T1/E1 and TCG3: T3/E3 & G.747), VoIP (ICG3) and Converged Test & Measurement (CTM-5000) in a single system:
