Depends on what you mean.  There has to be a telnet server on the mainframe side. 
Either on the mainframe itself or on some sort of front end box.  As far as who
does the 3270 keyboard and screen handling, that is the local tn3270 program.  If
you look at the packets on the wire, you will see that they contain EBCDIC
characters.

The mainframe really thinks it is talking to a 3270 tube so there is no additional
software needed for emulation on the mainframe.
