Multicarrier system with stored application profiles for supporting multiple applications

(57) The transceiver and method of communicating through the communications channel which has a subchannel of summary plurality are explained. Especially above-mentioned Tran Cibber can switch dynamically the communication data for application data sets of operation in which the second differs from the communication data for the first operation application data sets. As some communication data for the above-mentioned first operation application data sets, a transceiver assigns a subchannel to one or more applications in the first application set of the above. When a transceiver shifts to the communication data for the second application data sets dynamically, as for a transceiver, the above-mentioned subchannel is again assigned to one or more applications in the second application set of the above. In a certain enforcement form, a transceiver changes the data rate of the subchannel in a bit assignment table based on the communication condition (communication requirements) of the application with which the data is transmitted on a specific subchannel. In another enforcement form, the transceiver can switch the send data for Internet access applications to the send data for Internet access applications, and the send data for a voice telephone dynamically. Furthermore, in another enforcement form, an ABCD voice telephone emission bit can be transmitted with either of the data from Internet access application or voice telephony application.
