66.129.241.10

The page says: This abbreviation has several interpretations, the most common one being "Mobile Station International Subscriber Directory Number".

Based on the listed references, the most common interpretation or definition of MSISDN is "Mobile Subscriber ISDN Number."

In the listed references, "mobile subscriber" appears 4 times, but "mobile station" appears only twice. Consequently, "mobile station" is not the most common interpretation of MS, at least in these references.

I think the expansion of the ISDN portion to "International Subscriber Directory Number" is incorrect. In the abbreviations table, ISDN is (properly) never expanded.

I am unable to find in any of the listed references where ISDN is expanded to "International Subscriber Directory Number".

I can only find ISDN expanded to "Integrated Services Data Network".
