I did a lot of work on this topic around 1991-92 after having
coded a TCAP and MAP (Mobile Application Part) encoder/decoder
for a protocol analyser firm.

The ISUP was of prime importance for 20ieth century telecom.

I do not know about the 21. century but I am interested in hearing
views on this ?

I noticed that Siemens in their development efforts had one man
dedicated to hunt an abstract level definition of the ISUP.

These efforts were combined with others to form ASN.1/ECN.
(Pls. update/correct me if needed).

It would be a great thing to have an open doc. that described
the ISUP in ASN.1/ECN but I am aware that it must have cost some
man hours to develop so it can parse and generate encoders /decoders
that will go down the line and integrate with TCSP, MAP etc.

I have no connections with protocol analyser firms, telecomms
black boxes manufacturers etc. I work as a high school teacher
in maths/phys/computer science and I act as telecomms advisor
in my one man firm now.

I would be delighted to take on the task of writing a public
ISUP definition in ASN.1/ECN if anyone would pay me.
But I realise it would be quite some task.
