I waited a while for responses, but only got a few. Aparrently there
are not many managers out there using the Sun HSI boards. The
information I did receive said that the boards work fine, but that you
need a copy of Sun PPP to run them.
Many thinks to the respondents. They were:

Looking at the SunExpress catalog, it looks like when you buy an HSI
board, it comes with a CD-ROM. Contents of that CD-ROM are currently
unknown to me. The CD may contain a driver that is necessary to run
the boards. According to Glenn Satchell, one of the responding
sun-managers, SunLink PPP 1.0 has the necessary synchronous drivers.
I am going to get SunLink PPP 1.0 as recommended and try it out.
Unfortunately, I have not been able to test the suggestions presented
yet. When I have a working configuration, I will send a second

HSI has rs449 ports so you'll need a signal convertor to plug
your V.35 connection into the HSI. Black Box and others sell them.
My VME HSI board has two ports marked RS-449 and two ports marked
V.35. I think that Christian must be thinking of a different board
than mine--possibly the SBus variant, as I know nothing about that.

You need INR or PPP from Sun since you have a their HSI product.
I have some Sun's as routers using HSI and INR; it works.

Buy Sunlink PPP-1.0 from Sun, it includes the synchronous drivers
for the HSI board. The drivers included with the OS only provide
an asynchrounous driver. Once PPP is installed routing, etc, will
work fine using the standard in.routed supplied with SunOS.
This is what I am going to try.
also your hardware is interesting, a 4/350, if it's not a typo
then it must be a 4/300 cpu in one of the old 6 slot vme cages.
That is exactly the hardware configuration I have.

I was hoping that a summary would come across the Sun Managers
list of what replies you received. Since I haven't seen one yet,
did you get any further info on the 56k line? We have an IPX
running as a WAN hub and many of the pieces of hardware you
describe (except we will be using a switched 56 line instead of
dedicated). I've already asked Morningstar about their PPP
product which unfortunately, doesn't support our setup. Any help
you care to provide would be appreciated.
Sorry about the lateness of this summary. The managers were helpful,
and I was (as usual) very busy.

-------- Original Question --------
Subject: Connecting a 56k leased line to a Sun
Date: Fri, 18 Mar 1994 02:42:13 PST
From: Mark Epstein <firstname.lastname@example.org>
I have a pile of parts and a problem:
** The parts **
1. A Sun 4/350 running SunOS 4.1.3.
2. A Sun VME HSI (high-speed serial interface) board.
This board has two RS-449 and two DB25 V.35 connectors on it.
3. A 56k leased line, connected on my end to...
4. A CSU/DSU with a V.35 telecom-style output.
** The problem **
I want to use my Sun as a router between the 56k leased line
(running PPP or SLIP or something) and my local net, using the HSI
board's V.35 port?
I tend away from using the RS232 interface on the CSU/DSU to my system
board's serial port, because the interrupt rate would drag system
performance down into the muck.
Thanks is advance for your help!
