ATM SWITCHING UNIT

摘要

A transmission line control processor performs various processes in response to requests of a call processor for capture, allotment, and release of a subscriber line or an inter-station line. Additionally, in response to requests of the call processor for a reservation, connection, and disconnection of a path, the transmission line control processor instructs an ATM switch to connect or disconnect the path. These processes can be performed using with the existing functions of ordinary call processors, and such complicated processes as the management of bands at ATM switches are executed exclusively by a transmission line control processor.
