[comp.dcom.telecom] Sync vs Async and Misc. Questions About Leased Lines

jessea@rutgers.edu> (04/12/91)

Our company is in the process of hooking up seven remote sites using
leased lines.  To help understanding of the problem, I'll provide
background information.  We've got a Sun Server at the main office and
high powered PCs running unix and tcp/ip out in the branch offices.
We would like to have the PCs used to access the database at the main
office via high speed digital lines (19.2kb or 56kb lines) using
tcp/ip (we are using Oracle as the database).

What hardware do you recommend to do this and how?  Should sync or
async be used?  What should be used on the PC end to connect to the
line?  Does it need some sort of board that runs sync that you connect
the DSU to?  Because we have enough offices to make up for the cost,
AT&T is recommending that we have a full T1 going to our POP.  I
assume this requires special hardware?  I would appreciate any help
with this as it is completely new and confusing to all of us here.
I'm sure that we can get the job done -- I just want it done right.
Thanks much.
