To answer both questions - first one, yes, it have full 64kb of RAM but
part of the space are taken up by ROM which is 24kb, You could check out
the memory map of the system memory.
Second question, I do not know how to do it, it have to be done in a
machine code program.
Thanks for asking!
P.S. I own a orignal TS2068 with Aerco disk drive system and a Tandy
color CGA monitor

It really has 48K of RAM.

I have a Timex Sinclair 2068. I know nothing specific about it. Some
of you are experts.
Here is my question:
Does it really have 48K RAM, or does it actually have 64K of RAM?
If it actually has 64K of RAM, how would I bank-switch it to an all-RAM
configuration?

Sure, if you install a memory expansion cartridge or similar. I understand you
could buy these as cartriges at one time, and it is also possible to make an
internal expansion.

Is there any bank-switch configuration which would put RAM in the lower
16K ($0000-$3FFF) ?

It has 64K of address space, not 64K of RAM.
