[GreenKeys] Is that an answerback in this 28 ASR?

[John W9DDD]

My memory isn't completely gone.  
D with UC "WRU" is Teletype part 161077.

John, W9DDD

As mentioned before Teletype literature, used the term answerback in descriptions and parts books exclusively, I think. The terms seems to be used interchangeably by others here this side of the pond. As for what triggers it, it seems to be based on which customer system used it.  I've seen references to various UC letters.
