This is the up-down state of my 4Mbps line, this is actually a VERY good day. Telkom is the ISP as well, when queried with a month's stats of resets the answer was check your router. Not the router, Cisco 2610 with DSL linecard. Sometimes it is so bad that I have to reboot the router to get any through put.
