OPEN ATM SWITCHING SYSTEM AAL2 ATM PVC CONNECTION CONTROL METHOD THEREOF

摘要

The present invention relates to an open ATM switching system (asynchronous transfer mode switching system) and AAL2 ATM PVC (ATM Adaption Layer type2 Asynchronous Transfer Mode Permanent Virtual Circuit) for that connection method, the open ATM exchange system operator instruction using the middleware in the low-speed voice traffic in the mobile network as IMT2000 to use by controlling the AAL2 ATM PVC connections to perform (Human machine Interface) HMI command, the VOA (voice Over ATM) existing open ATM exchange system that did not support the AAL2 for it to be efficient bandwidth use.
