mpanl Sig Mpanl State Change

This attribute counts the number of times the SVC data link layer interface has changed state. Frequent state changes may indicate a problem with the line quality. While the data link layer is in informationTransfer state, this counter will increment on each expiry of idleProbeTimer as its state goes from informationTransfer to waitingAck and back. When this count reaches maximum, it wraps to zero.
