Abstract: PURPOSE: A method of sharing resources of a PVC(Permanent Virtual Connection) of an ATM exchange is provided to share resources of a PVC in other reserved mode while the resources of the PVC of a preset reserved mode are idle, thereby implementing resource using efficiency. CONSTITUTION: An MMC processor receives an MMC including a PVC request signal of a reserved mode, and checks a parameter condition of the MMC(S12), then decides whether an MMC condition is correct. A VPI/VCI processor checks whether VPI/VCI is allocated in a new PVC of a preset reserved mode(S14). If so, the VPI/VCI processor checks a period of a reserved time of the PVC(S18). If the reserved time is included in an idle time of a preset PVC, the VPI/VCI processor shares the VPI/VCI of the new PVC in the preset PVC(S19). A bandwidth processor calculates a bandwidth of the new PVC, and decides whether a bandwidth of a newly-requested reserved mode PVC is allocatable(S20). If so, the bandwidth processor checks a reserved time of a preset PVC of the bandwidth(S22), and decides whether the bandwidth is sharable. The bandwidth processor allocates the bandwidth of the newly-requested reserved mode to the bandwidth of the preset PVC(S26).
