OAMP, traditionally OAM&P, stands for operations, administration, maintenance, and provisioning. The addition of 'T' in recent years stands for troubleshooting, and reflects its use in network operations environments
Troubleshooting is carried out as a result of a fault or failure, may result in maintenance procedures, or emergency workarounds until such time as a maintenance procedure can be carried out. Troubleshooting procedures will involve knowledge databases, guides and process to cover the role of network operations engineers from initial diagnostics to advanced troubleshooting. This stage often involves problem simulation, and is the traditional interface to design.
