Behind this dataset
Same schema. As many rows as you need.
These 350 rows came out of a blueprint — 17 columns with generation rules behind each one. Open it in Data Factory to retune a column, add your own, wire in foreign keys, and run it at the size you actually need.
Rules it was built with
- Call ID and subscriber MSISDN for quality issue tracking
- MOS score: 1 (bad) to 5 (excellent), target >4.0 for HD voice
- POLQA score: ITU-T P.863 standard for wideband/super-wideband speech
- Jitter (packet delay variation) in milliseconds (target <30ms)
- Packet loss percentage (target <1% for acceptable quality)
- Codec used: AMR-NB (narrowband), AMR-WB (wideband), EVS
- One-way delay (mouth-to-ear latency) target <150ms per ITU-T G.114
- Echo (acoustic/network) ERLE (Echo Return Loss Enhancement) in dB
