Communication error processing

The types of communication error that can occur include terminal error processing and intersystem communication failures.

Terminal error processing
There are two main CICS® programs that participate in terminal error processing. These are the node error program, DFHZNEP, and the terminal error program, DFHTEP.
Intersystem communication failures
An intersystem communication failure can be caused by the failure of a CICS region, or the remote system to which it is connected. A network failure can also cause the loss of the connection between CICS and a remote system.
