[comp.dcom.telecom] Info on HDLC and Stromberg-Carlson

pat@cs.washington.edu (Pat Myrto) (03/10/91)

Where I work, we are using a Stromberg-Carlson switch (and an older
one at that), and need to set up a link using their version of HDLC to
a PC running DOS, on a Novell Netware LAN, or if nothing is available
for that, to a UNIX system running ISC 386/ix.  Purpose is to get call
detail information from the switch in real time - as the switch writes
the information to tape, it would also send it via this link to the
computer system.  The media will be a leased line, as the location of
the switch and the processing site are miles apart.

What I have found out so far is the HDLC the S-C switch uses is
non-standard in some areas, so the ability to alter the driving
software on the receiving end is needed.

Has anyone out there done ANYTHING like this, or know of anyone that
has successfully?  Failing that, what vendors would I check with for
the needed hardware/software to set up an HDLC link on the PC or UNIX
side, and perhaps some books on the subject - I need all the
information on this I can get.

Lacking any of the Stromberg-Carlson specific stuff, *ANY* help,
pointers and so on regarding HDLC would be appreciated.  I have never
worked with this protocol, so I have to truly start from square one.

I doubt if this is going to be of interest generally (I understand the
Stromberg-Carlson switch is not the most widely used), so e-mail
replies would probably be the best.  I can summarize to the net if any
interest materializes.

Thanks for any help you can offer...
