COM XVIII/92 102

Started by jan_trmal April 28, 2003
Hi all,
I'm looking for specs of this standard. It's mentioned in the G.726 Annex III,
with two
citations -- US-patent nr. 4860313 and then with the following annotation:

Israke, Voiceband data optimized algorithm - Detailed description, Document No.
COM
XVIII/92 CCITT Study Group XVIII - Ad Hoc Group DCME - Base solution for
Voiceband
Data Transparency, Stockholm, April, 1987.

I've tried to look for this doc on google and on www.itu.int, but without any
success.
Does anybody know where to get this document? I'm also looking for some
conformance test vectors for this ADPCM (similar to G.726 test vectors). Each
hint
appreciated. Thanks
Yenda
