phone display.
Error Message

Phone
Possible Cause Action
Connect Error
V42 Connect
Failed
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 2
nd
blink of the
LED sequence on the Switch
Card. If it is RED, the
problem is with the Lucent
ECS digital port. Check the
cabling on the 50 pin
connector according to the
Tables in Chapter 3.
If the 2
nd
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 6-16 to
6-18.
