Why is time division multiplexing (TDM) used in the physical layer?

We know that in the physical layer, we don't use any multiplexing, and Ethernet is a baseband channel which carries a digital signal, but I read in the Wikipedia article that TDM is used multiplexing ...

TDMA in telephone circuit switching - isn't there delay in transmitting a particular user's speech? [closed]

Let's do a simple case on the left with X and A user telephones. So the way an analog signal (user's speech X) is handled, is that it is sampled at 8000 bits / sec. The high-speed C-channel has 128 ...
