    摘要: An arrangement and method for switching a single destination data channel to a different destination without losing any data messages. Such a switch is required, for example, when a switch is made to a standby control unit and the messages originally destined for the original active control unit must be sent to the standby. Received messages are drained from the source prior to making the switch. Appropriate data is copied from the active unit to the standby so that the standby unit is in a state to start accepting newly queued messages from the source.
