defined as follows:

WAIT FULL STATUS

The LMI state entered when the local frame relay software has transmitted a STATUS

ENQUIRY message requesting a FULL REPORT STATUS message.

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.

Current LMI alarm condition. When this item is TRUE, the LMI alarm is on, and all associated

PVCs are unavailable. When this item is FALSE, the alarm condition is clear.

reset when N392 is reached. (The N391 parameter is the configured Full Status Enquiry Polling

Count, and the N392 parameter is the configured Error Threshold Count.)
