Abstract
A data transfer method includes a connection establishment step of detecting connection with a remote device and setting parameters for data transfer, and a transfer execution step of starting data transfer after completion of the connection establishment step and continuing data transfer until a transfer error is recognized to have occurred. In the transfer execution step, the frequency of errors in received data is monitored and, when the frequency reaches a predetermined value, a transfer error is recognized to have occurred.
Claims13
A data transfer method comprising a connection establishment step of detecting connection with a remote device and setting parameters for data transfer, and a transfer execution step of starting data transfer after completion of the connection establishment step and continuing data transfer until a transfer error is recognized to have occurred,
- wherein, in the transfer execution step, frequency of errors in received data is monitored and, when the frequency reaches a predetermined value, a transfer error is recognized to have occurred.
A data transfer method that achieves bidirectional data transfer using a single optical fiber, the data transfer method comprising a connection establishment step of detecting connection with a remote device and setting parameters for data transfer, and a transfer execution step of starting data transfer after completion of the connection establishment step and continuing data transfer until a transfer error is recognized to have occurred,
- wherein codes are allocated in such a way that codes a local device can transmit include codes the remote device cannot transmit, and, in the connection establishment step, a transfer error is recognized to have occurred when a code the remote device cannot transmit is received.
A data transfer method comprising a connection establishment step of detecting connection with a remote device and setting parameters for data transfer, and a transfer execution step of starting data transfer after completion of the connection establishment step and continuing data transfer until a transfer error is recognized to have occurred, the transfer execution step comprising a synchronization establishment step of establishing character synchronization, and an ordinary transfer step of conducting ordinary data transfer after completion of the synchronization establishment step,
- wherein, when a transfer error is recognized to have occurred in the ordinary transfer step, execution proceeds to either the connection establishment step or the synchronization establishment step according to a time that has elapsed after the ordinary transfer step was started.
