- memling 5y agoASN.1 standards are free: https://www.itu.int/rec/t-rec-x.680/en https://www.itu.int/rec/t-rec-x.680/en Many, though not all, specifications that use ASN.1 are also freely available. I've been out of telecom for awhile, so I don't know the status of the newer standards, but when I was working in the business GSM MAP and MMS were the only proprietary ones that were an issue.
- userbinator 5y agoGSM standards are also freely available --- look at 3gpp.org or etsi.org --- the biggest problem is finding which ones actually contain what you're looking for.
- cryptonector 5y agoThe ITU-T ASN.1 specs have been free for a very long time now. They used to be non-free, and that was a big problem with ASN.1, but that was decades ago.
