Telkom has released its latest ADSL Key Performance Indicators (KPIs), captured between 1 April 2009 and 6 July 2009. Telkom KPIs – a requirement of the ICASA ADSL regulations – were previously dogged by inaccuracies and mistakes, and the company moved from a fairly comprehensive set of results to a trimmed down version providing significantly less detail.<\/p>\n
Three performance indicators form part of Telkom’s KPI reports: Packet Loss, Latency and Jitter. Each of these performance indicators are provided for Telkom’s national and international networks.<\/p>\n
