With the advent of data streaming, a new data transfer mechanism for I/O channels, it is clear that I/O devices are capable of transferring data in two modes. By using the data streaming method of transfer, the devices and channels communicate at a high rate independent of cable lengths. The other data transfer mode, DC interlock, allows the device to be compatible with slower hardware. In general, devices can choose to operate in either or both modes depending on their characteristics. However, because a multipath channel-to-channel adapter connects to both fast and slow channels, it needs the ability to run any channel in either mode on a dynamic basis. This can present several problems.
