Patent ID: 7809014

Claim:
A device configured to communicate voice data under an ATM protocol, the device comprising: a communication interface configured to receive a full-rate voice data signal, wherein the full-rate voice data signal comprises one or more frames, wherein each frame includes a segment of full-rate voice data, wherein the segment of full-rate voice data included in said each frame is 24 bytes; an ATM Adaptation Layer 0 (AAL0) cell-generation system configured to generate an AAL0 cell that corresponds to each of the one or more frames, wherein each AAL0 cell comprises: a header field, wherein the header field is 5 bytes; a data field comprising the segment of full-rate voice data included in the frame, wherein the data field in said each AAL0 cell is 24 bytes; a PAD field for padding the AAL0 cell such that the size of the AAL0 cell is in accordance with the ATM protocol, wherein the PAD field is 3 bytes; a 1-byte length field containing information for indicating a size of the segment of full-rate voice data included in the frame; a 19-byte control-data field containing information for controlling the full-rate voice data signal; and a 1 -byte error-detection field containing information usable to detect one or more data errors in said full-rate voice data; and a cell-processing system configured to generate an ATM Adaptation Layer 2 (AAL2) cell corresponding to each generated AAL0 cell, wherein each AAL2 cell comprises a data field that includes the segment of full-rate voice data from the AAL0 cell from which the AAL2 cell was generated, and wherein the device is further configured to send the AAL2 cells to a base station controller (BSC) in a CDMA network; wherein the device is a base transceiver station (BTS) in the CDMA network.
