Hope someone can help.
Our ADSL line connected to our Cisco 877 is suddenly Down/Down. The provider has made me sure that the link was just fine. They tested it with a Layer 3 adsl tester.
I notice that the carrier detect (CD) Led in the front panel is keep blinking even after the pots cable is unplugged. Is this normal?
When the Dslam isn't compatible with the 877's firmware, should it be down/down or up/down?
Any comment will be appreciated.
