Leased line usually has some Quality of Service level and a minimum repair time at least on any we have used. It may vary in different countries/regions

Could you elaborate on your experience please? – Everyone May 28 '11 at 15:17
A leased line may guarantee 1.5Mbps synchronous. Speed could be anything but it is assured. ADSL is best effort with many factors impacting actual delivered speed. Leased line will usually have a guarantee of repair time. Sometimes 4 hours but it is spelled out. ADSL is usually not so simple easy to get a repair. – Dave M May 28 '11 at 15:23
