WAIT T391 TIMEOUT
The LMI state entered when the local frame relay software has received a STATUS message
from the network in response to a previous STATUS ENQUIRY and has restarted the T391
timer. (The T391 parameter is the configured Link Integrity Verification Timer.)

The LMI state entered when the local frame relay software has transmitted a STATUS
ENQUIRY message requesting a LINK INTEGRITY VERIFICATION STATUS message.
