About Communication In

These transactions represent a message sent from an external system and are received in two situations:

• In response to a communication that had been sent to the external system. This is the most common usage of the communication in.

• An unsolicited message received from an external system such as a real time event. Note: this is not a common pattern.

• Upon receipt the communication in will link itself to the communication out that initiated it. The response message will then be validated to ensure that it is technically and functionally correct.

• For many smart meter commands and field activities executed by service order management the communication in is responsible for creating the appropriate completion events. For example, if the response was for the On Demand Read smart meter command a completion event will be created that will generate the appropriate initial measurement data.

• Similar to the communication out a communication in that encounters an error can perform an automated retry with a configurable rate of retry and number of retry attempts.
