The IS-641 is a North American TDMA Cellular standard, so I do not think the ETSI has it. for the documentation : http://www.tiaonline.org/standards/search_results2.cfm?document_no=TIA /EIA/IS-641-A for the C-code, I guess they also sell it. In the ETSI site (www.etsi.org) you can download the description and the C-code for the following GSM codec standards: HR, EFR and NB-AMR (for the FR only the description). I think they let you download this standards, free of charge, even if you are not a member.
