I have been experiencing this problem in Argentina since about 6 months.
Before then, you could remain connected as long as you wished.
But then they began slowly increasing the delay between the time the phone
call was answered and the actual connection started, from about 20 - 30
seconds to a minute and a half. And now, usually the connection breaks
exactly after you download a medium size file, or otherwise use a large
chunk of bandwidth. This seems to be a way to increase phone companies'
revenue, because probably phone companies own most ISPs. In other words:
1) A minute more of line usage each time you connect.
2) The same after you reconnect following a connection break.
3) Wait for a download to end in order not to raise many complaints.
