Cisco 1720 keeps loosing conectivity
Posted on 2007-03-19
I have a cisco 1720 router with a csu/dsu card. We use the router to connect to our wan and configure our VOIP phones. Lately, the router has been loosing contectivity intermittely. It will be down for about 10 seconds, just long enough to knock the phones out and know them off of an application that we use. Does anyone have any idea why this is happening or how to prevent it.
The frequency has increased since they replaced a transformer on the main power line.
