using VT terminals with remote systems?

The Question is:

 
How can I make DEC VT200 terminals, that are connected to
an Alpha station by a DEC terminal server, communicating
with a Unix-system on distance?
I want to have access to software which is running on a
Unix-server that can be connected by a router and
receiver to our Alpha station using ISDN 2. The meaning
is that we can use our DEC-terminals as "workstations"
for the Unix-server, so that we can communicate to the
software on that Unix-server.
I am familiar with the fact that you can use Unix- or
Windows-software to have access to the Alpha by using
some kind of terminal emulation.
But is it possible to do the same the other way round?
 

The Answer is :

 
  VT200 series terminals are the terminal devices that are being emulated
  by the software you are familiar with.  The VT200 series terminals all
  depend on external devices -- such as a terminal server -- for network
  capabilities.  Direct connections to the host system via a standard
  serial line are common, and remote (network) connections can be made via
  the configuration of a directly-connected host system or terminal server.
 
  Depending on the particular terminal server in use, network connections
  to the host can be made via LAT or IP protocols.   (Various older DECserver
  terminal servers support LAT.  Newer DECserver terminal servers typically
  support both LAT and IP.)
 
  Depending on the particular UNIX system, you may have access to LAT client
  software.  UNIX systems typically permit connections via IP protocols.
 
  With a requirement for routing, IP is likely an appropriate choice.  LAT
  can be "bridged" to a remote network segment, but there is no LAT router
  available.
 
  In this particular case, you can telnet (IP) or SET HOST (DECnet) from the
  Alpha system -- the system that is hosting the VT200 terminals via a serial
  line or LAT -- to the remote system.  This would require IP or DECnet on
  both platforms -- most UNIX systems have an IP stack, and OpenVMS permits
  various IP stacks including TCP/IP Services for OpenVMS (UCX) as well as
  third-party IP stacks.
