PURPOSE: A method for processing PM(Performance Monitoring) data of a transmission system is provided to enable the PM data to be delivered efficiently, when a main controller stores data reported from a transmission equipment and form the PM data. CONSTITUTION: Each sub controller collects and accumulates PM data whenever a fault is generated(S510). Whether a fault is generated in a transmission equipment is checked(S520). If not, a zero flag field is maintained to 0(zero), and if generated, the zero flag field is changed to 1(one)(S530,S540). A main controller checks whether 15 minutes, a predetermined time interval, passes(S550). If so, each sub controller reports PM data to the main controller(S560). The main controller checks whether the zero flag field is 1(one), to see whether the PM data are actually accumulated PM data(S570). If so, the main controller stores the PM data in a register(S580).
