I don't know "NUA" either, but a quick check of CCITT Recommendation
X.121 shows that the country code assigned to Argentina is 722, so the
"7222" part is the DNIC (Data Network Identification Code) of an X.25
network in Argentina, and the "211103127" part is the address of a
host on that network.

Or this could apply to some communications network who has adopted the
X.121 addressing conventions (much as Telenet adopted the telco
numbering plan for its internal addressing).
