TDM was developed for the PSTN.

TDM allows the transmission of isochronous traffic (time and bandwidth
critical traffic). TDM over a point to point link guarantees bandwidth.
Synchronous line transmission (one end owns the clock, the "master")
provides guaranteed interframe latency.

In a lan (CSMA) you can use qos to (hopefully) guarantee bandwidth and
jitter buffers to (hopefully) guarantee interframe latency.

And I never used the words T, DS, OC, bit-robbing or super frame :-)
