The adapter driver was not in a working state when 
LoopTest was launched. Possible causes are:

•  The adapter is not installed.

•  The driver is not installed, or is improperly installed.

•  The firmware is invalid (ISDN layer not present) or 

not loaded. To check the firmware status:

a. From the Start menu, select Programs, then 

INTERPHASE WAN Adapters, and then WAN 
Setup. 

b. See if the microcode is loaded (LEDs must be 

green), and check its characteristics (ISDN layers 
must appear).

This error occurs in the following situations:

•  You are executing more than the maximum 15 

instances of LoopTest.

•  The driver is not installed, or is improperly installed.

The connection cannot be established, and the ISDN 
network has not supplied a reason. This error generally 
occurs when the dialing number is wrong.

The connection was cut off during data exchange with 
no notification from or to the network. This error 
generally occurs when the ISDN cable is removed 
during testing.
