CONSTITUTION: An ISDN(Integrated Services Digital Network) PRI performs an initialization relating to PRI resources between a BSC(Base Station Controller) and an IWF(210). The ISDN PRI checks a trunk line error and changes an STS(E1), depending on whether the error is generated(212). The ISDN PRI decides whether the STS(E1) value is normal(216). If not, the ISDN PRI updates trunk lines, every time slot of the trunk lines, and channel states into anormal states(213). If the STS(E1) value is normal, the ISDN PRI checks a failure relating to the time slots, and changes an STS(TSi) and an STS(TSj) according to the failure(218). The ISDN PRI decides whether an optional time slot included in a CHn, a state of the TSi, and the STS(TSi) are changed. If so, the ISDN PRI updates an STS(CHn) value on the basis of a mathematical formula 3(222).
