“…introduce the auxiliary concept of first-signal…defined as the fastest message carrier between any two points in space. We now send a first-signal from P, calling the event of departure E1… The event of its arrival at P' is called E'. Simultaneously with the arrival of this signal, another first signal is sent from P'. The arrival of this signal at P is the event E2. …the time interval between E1 and E2 is coordinated to the event E', [E1 is earlier than E' and E2 is later than E'] and every event of this time interval except for the endpoints is inderterminate as to the time order relative to E.”

“Occasionally one speaks… of signals or signal chains.”
It should be noted that the word signal means the transmission of signs and hence concerns the very principle of causal order...
