Recovery From A Failed Ethernet Connection - Siemens DCA Vantage Operator's Manual

Recovery from a Failed Ethernet Connection

If the Ethernet connection to the LIS fails (goes down) and is subsequently
restored, the system tries to retransmit only those patient or control test results
that have a transmission status of Sending. When the transmission succeeds,
the transmission status is updated accordingly.
If this is an ASTM connection, a transmission is considered to be failed if 72
hours have passed since the most recent transmission after a good
connection went down, and the LIS did not receive the message on
subsequent attempts to transmit it.
