So what would the data in the packet start with? Would these be MAC- layer messages (possibly with some metadata)?
And is "US-DECT" a US-specific scheme? http://www.dectweb.com/LearningZone/WDCTTech.htmclaims that the "W" in "WDCT" is "Worldwide", but also claims that it'sUS-specific. (BTW, does "US" in this context mean "US and Canada" or "North America" rather than just the US?)I cannot say what countries are covered by WDCT other than the US. Alsothis standard is not part of our work. I just wanted to mention that there's another variant out there, and you may want to keep them as "neighbours" in the #define LINKTYPE_* set.
So perhaps I'll just call it WDCT (that's what Siemens appears to call it, and they appear to be the ones who developed it), hence LINKTYPE_WDCT/DLT_WDCT.
Are there any published specifications for it, or is that only specified in internal Siemens documentation?
