communications questions

[Charles Hedrick]

We are trying to set up a Sun 3 as a "communications server".  We want
it to do the following:
  - handle UUCP mail for all of the machines on our Ethernet
  - interface between Ethernet and BITnet
  - handle various network servers and daemons.
We have reason to think that what we are trying to do is possible, but
I am finding it hard to issue actual purchase orders for a couple of
the pieces.  I'd be curious if anyone knows what pieces we would
need for the following:
  - interface to BITnet.  This requires us to talk to an IBM
	machine as if we were an IBM host.  We believe UREP from
	Penn State will do this, and we have ordering information
	for it.  However we don't know whether anyone has used
	this on a Sun.  It needs to talk to a synchronous line
	using bisync.  Does anyone know that this has been done,
	or have a suggestion for a way to support a high-speed
	bisync line on a Sun?  (Sun has a Hasp RJE product, but
	we don't want to emulate a card reader.  It is not clear
	whether we can use just the lower level of this product
	to implement UREP.
  - Arpanet interface.  Does anyone have a Sun on the Arpanet?
	What 1822 interface do you use?  What  1822 device
	driver/software?
