Data communication apparatus and data communication method
First Claim
1. A data communication apparatus that exchanges a voice packet via an IP network, the apparatus comprising:
- a data processor that executes a standard communication mode and a high-speed communication mode, the voice packet including non-voice data and being exchanged at a predetermined transfer rate via the IP network in the standard communication mode and at a rate faster than the predetermined transfer rate via the IP network in the high-speed communication mode, the standard communication mode and the high-speed communication mode being interchangeably executed;
an acceptor that obtains capability information of a remote apparatus in accordance with a predetermined communication protocol; and
a controller that selects the high-speed communication mode for execution based on a determination, using the capability information, that the remote apparatus is configured to execute the high-speed communication mode.

Abstract
A data communication apparatus is provided with a VoIP processor and a modem that interchangeably executes a standard communication mode and a high-speed communication mode, the standard communication mode exchanging the voice packet at a predetermined transfer rate, the high-speed communication mode exchanging the voice packet at a rate faster than the rate of the standard communication mode. When capability information of an opposing apparatus is obtained, in accordance with a predetermined communication protocol, and it is detected that the opposing apparatus has the high-speed communication mode, the high-speed communication mode is selected for execution.

8. A data communication method that exchanges a voice packet via an IP network, the method comprising:
-
obtaining capability information of a remote apparatus in accordance with a predetermined communication protocol, the capability information indicating whether the remote apparatus is configured to execute a high-speed communication mode in which the voice packet, including non-voice data, is exchanged at a predetermined transfer rate via the IP network; determining, using the capability information, whether the remote apparatus is configured to execute the high-speed communication mode in which the voice packet is exchanged at the predetermined transfer rate; transferring the voice packet in the high-speed communication mode based on determining that the remote apparatus is configured to execute the high-speed communication mode; and transferring the voice packet in a standard communication mode based on determining that the remote apparatus is not configured to execute the high-speed communication mode, the voice packet being exchanged in the standard communication mode at a standard transfer rate lower than the predetermined transfer rate. - View Dependent Claims (9, 10)

11. A facsimile apparatus that communicates with a terminal via an IP network, the facsimile apparatus comprising:
-
a transmitter that transmits a voice packet to the terminal via the IP network; a receiver that receives capability information of the terminal from the terminal via the IP network, the capability information indicating whether the terminal is configured to execute a high-speed communication mode in which the voice packet is exchanged at a first transfer rate; a VoIP processor that performs a first data conversion between the voice packet and voice data; a modem that performs a second data conversion between the voice data and facsimile data; and a controller that determines, using the capability information, whether the terminal is configured to execute the high speed communication mode, wherein the transmitter transmits the voice packet at the first transfer rate when the controller determines that the terminal is configured to execute the high-speed communication mode, and transmits the voice packet at a second transfer rate, lower than the first transfer rate, when the controller determines that the terminal is not configured to execute the high-speed communication mode. - View Dependent Claims (12)
