摘要： PURPOSE:To change a priority degree given to communication, from a called side terminal equipment, too, by giving the first priority degree and the second priority degree to a calling side terminal equipment and a called side terminal equipment, respectively, comparing the first priority degree and the second priority degree, and selecting one of them as a priority degree of the communication between the calling side and the called side terminal equipments. CONSTITUTION:A priority degree selecting part 52 compares the first priority degree extracted from a call control memory 32 and the second priority degree which is received, for instance, with a priority degree designated by a call side terminal equipment and a called side terminal equipment, respectively, and the higher priority degree is adopted. Or the comparison is executed by a prescribed logic for adopting unconditionally the priority degree designated by the called side terminal equipment, etc., and the priority degree to be adopted is selected to a call set between the calling side terminal equipment 21 and the called side terminal equipment 23. The priority degree selecting part 52 selects the second priority degree in case the called side terminal equipment 22 is contained a desire of the priority degree in an incoming call allowable signal c3, and selects the first priority degree in case the called side terminal equipment 22 is not contained the desire of the priority degree in the incoming call allowable signal c3.

摘要： PURPOSE:To prevent an ineffective packet from being generated in great quantities by discarding a packet whose repeating stage number has exceeded a prescribed value, also sending out a repeating unallowable packet toward a transmitting station of this packet, and controlling the inflow of a traffic by the transmitting station. CONSTITUTION:When a fault is generated in a repeating station on a path passing through a repeating station B, and a data packet DT2 reaches a repeating station Y, on a path passing through a repeating station C, the number of repeating stages of the data packet DT2 increases due to the repetition of an alternative routing, a signal for showing a fact that this value has reached already a prescribed value for discarding the data packet DT2 is applied to a discard control part 1, a repeating unallowable packet CGR is generated by this discard control part 1, and this repeating unallowable packet CGR is sent out to a transmitting station A from an information transmitting part 2 of the repeating station Y. An information receiving part 3 of the transmitting station A receives this repeating unallowable packet CGR, it is transferred to a traffic control part 4 of the transmitting station A, and this traffic control part 4 is shifted to a controlled state.
