Maintenance Associations (MAs) .
Configuring Pseudowire Maintenance Associations (MAs)
Maintenance Associations (MAs) define Maintenance End Points (MEPs), and perform continuity checks by sending
Continuity Check Messages (CCMs) between the MEPs. This is the mechanism by which PTP 820G or PTP 820F
monitors the status of both paths in a protected TDM service and determines when a switchover is necessary.
For PTP 820F and PTP 820G, You can configure up to 32 MAs per unit.
