摘要： The invention provides a variable length frame exchanging method adapted to a fixed length cell handling exchange into which a terminal for use with a data communication method by a variable length frame is accommodated, a variable length frame exchanging interface apparatus and a call acceptance determination system, which are improved in that a variable length frame can be exchanged at a high speed in a fixed length cell handling exchange network and a terminal can be connected to and accommodated into the exchange in the same conditions as an existing service. The terminal is connected to the exchange by way of a subscriber line including a plurality of channels. A variable length frame from the terminal is disassembled into fixed length cells, and a use channel number or numbers and a DLCI of the subscriber line are converted into a VPI and a VCI. The VPI and the VCI are added to each of the fixed length cells, respectively, and the resulted fixed length cells are inputted to the exchange so that the frame is exchanged by the exchange.

摘要： There is provided an ATM switch including: an input line unit for terminating ATM cells input via an input connection; an output line unit for outputting ATM cells to an output connection; and a switch unit for switching a first ATM connection formed by linking a first input connection with a first output connection via a first internal connection, to a second ATM connection, which has the same bandwidth and quality as the first ATM connection, formed by linking a second input connection with a second output connection via the first internal connection. With this arrangement, when the first ATM connection is changed by channel switching to the second ATM connection, the first internal connection at the first ATM connection before the switching is employed for the linking of the second input connection with the second output connection at the second ATM connection. Therefore, the process for releasing the first internal connection and the process for setting a new internal connection are not required, and the ATM connection can be switched in a moment.

摘要： A bandwidth table holds a CBR bandwidth about a bandwidth that a CBR connection can occupy. A CAC unit controls whether or not to permit the establishment of a CBR connection while performing an overbooking bandwidth control for permitting a currently used bandwidth to exceed the CBR bandwidth, based on the CBR bandwidth set in the bandwidth table and the use state of the current CBR connection, when establishing the CBR connection.
