Record type 57 is written whenever JES3 completes a network transmission and the connection to the next node is BSC. When the connection is SNA, JES3 does not write the record; BDT writes record type 59 instead. Record type 57 contains original and current job identifiers, accounting information, transmission path, and destination.
