[Prior art]
ITU-T Recommendation V. A conventional communication device capable of communication of the V.92 standard is called V.92. A new modem on hold function has been added to the 90. The modem on hold function responds to the modem hold request when the partner side receives the modem hold request, holds the line, and resumes data transmission after this mode ends.
[0003]
[Problems to be solved by the invention]
However, ITU-T Recommendation V. At 92, when there is a modem hold request from the other party, an acknowledgment signal is always sent to hold the line, and after this mode ends, data transmission is started again. During this time, the line is, for example, in voice mode.
[0004]
Here, for example, even when the user is not at home, the voice mode is set, so that the line is invalidated, the communication time is lengthened, and the communication cost is increased.
