The earliest work I know about was indeed from Bell Laboratories: https://en.wikipedia.org/wiki/Time-assignment_speech_interpolation <https://en.wikipedia.org/wiki/Time-assignment_speech_interpolation>. This may be what Chu was referring to.
Time assignment speech interpolation (TASI) was a statistical multiplexing technique to increase channel capacity of expensive (overseas) cables.
Evidently the first TASI links were in service in mid-1960.
The semi-official record seems to be https://ieeexplore.ieee.org/abstract/document/6773473 <https://ieeexplore.ieee.org/abstract/document/6773473>
I remember learning about this while doing Ethernet voice at PARC circa 1979.
