Abstract: A network interface of a UMTS radio network controller encapsulates incoming AAL2/AAL5 packetized data such that it can be used on an Ethernet based IP network. A hardware unit is used to calculate additional information for the protocol overhead, including calculating length and error checking values. A partial header information is stored and used for each encapsulated packet of a session. In a preferred embodiment, the incoming packets are buffered in a linked data buffer including a linked list with pointers to the partial header information for the session as well as pointers to the incoming packets.

Abstract: In the context of making a cell-loss-sensitive connection between an originating subscriber device and a destination subscriber device via an ATM coupling field, a connection is set up only if the sum of the connection bandwidths of cell-loss-sensitive connections, executed via a logical point-to-point connection connecting the destination subscriber device with the ATM coupling field and in the process of being made, is less than or equal to a predeterminable limit value. All other connections are set up without checking.

Abstract: An ATM interface device (SS) that is connected via a first data bus (SAR_DAT) to a first ATM device (SAR) implementing an access coordination of the first data bus (SAR_DAT) and that is connected via a second data bus (ATM_RDAT, ATM_TDAT) to a second ATM device (MUX) implementing an access coordination of the second data bus (ATM_RDAT, ATM_TDAT) is provided for a data transmission. The ATM interface device (SS) comprises a control module (CC) and two FIFO memories (R_FIFO, T_FIFO) for intermediate storage of data to be communicated.

Abstract: An ATM interface device (SS) that is connected via a first data bus (SAR_DAT) to a first ATM device (SAR) controlling a data transfer and via a second data bus (ATM_TDAT, ATM_RDAT) to a second ATM device (MUX) [sic] controlled by a data transfer is provided for a data transmission. The ATM interface device (SS) comprises a control module (CC) and two FIFO memories (T_FIFO, R_FIFO) for intermediate storage of data to be communicated.
