This Business ADSL</b> service has been developed mainly for the conservative business user who requires the assurance of an uninterrupted and fixed cost ADSL service.The Business ADSL Express service is a managed service, whereby the customers usage is monitored and recorded. The service is allocated a certain threshold for the month which is divided into a 10 day rolling window. If a customer reaches his 10 day threshold before the 10th day, his bandwidth will be halved (e.g. 512Kbps to 256Kbps 1MB to 512K). However, if his consumption is reduced, his bandwidth will be restored to the purchased level.This mechanism has been put in place in order to discourage abuse of the service and thereby giving the conservative business user a more superior service.<br><br><b>The thresholds are as follows:</b><br><b>512</b> = 30 Gig for 30 days which is divided in 3 segments of 10 Gig each. The usage is monitored over a 10 day rolling window period.
Can't really call this uncapped! Are all IS uncapped accounts based on a similar principle? And what is the threshold?
