What is adnFrAtmSerIWUserT391?

This OID reads the T391 timer value for the user side, which is the polling interval between link integrity status checks on the frame relay interface. Network engineers adjust this timer to control how quickly the device detects a dead link. For example, a T391 value of 10 seconds combined with N391=6 means a full status cycle takes 60 seconds, so link failure detection occurs within 1 minute.
