Could not negotiate the error correcting protocol. The likely cause is either extreme noise on the modem connection or the Switch Card cannot recognize a Lucent ECS digital port.
Observe the 2nd blink of the LED sequence on the Switch

If the 2nd blink is green, the problem is likely due to lost data packets associated with phone line noise. Check the Switch Card statistics and look for error codes as described on pages
