Alternatively to my first proposal but still overloading the original xtables I
came up with another solution which does not have the \NC\NR but only \NR and
does not read the cell content as an argument.
\unprotect
% Overload tabl_x_start_table
\unexpanded\def\tabl_x_start_table[#settings]% maybe two arguments:
[tag][settings] | [tag] | [settings]
{\bgroup
\let\NC\tabl_xte_start_nc
\let\NR\tabl_xte_start_nr
\settrue\c_tabl_xte_first_nc
\tabl_x_prepare{#settings}%
\edef\tabl_x_current_buffer{\tabl_x_default_buffer}%
\buff_pickup{\tabl_x_current_buffer}{startxtable}{stopxtable}\relax\tabl_x_process\zerocount}
% xtable extensions
\newconditional\c_tabl_xte_first_nc
\unexpanded\def\tabl_xte_start_nr
{\stopxcell\stopxrow
\settrue\c_tabl_xte_first_nc}
\unexpanded\def\tabl_xte_start_nc
{\ifconditional\c_tabl_xte_first_nc
\setfalse\c_tabl_xte_first_nc
\expandafter\startxrow\expandafter\startxcell
\else
\expandafter\stopxcell\expandafter\startxcell
\fi}
\protect
\starttext
\startxtable[align={lohi,middle}]
\NC OSI-Schicht \NC[nx=6] Umsetzung \NR
\NC Anwendungsschicht \NC[nx=2,ny=3] SOME/I \NC[nx=2,ny=3] AVB/TSN
\NC[nx=2,ny=3] DoIP \NR
\NC Darstellungsschicht \NR
\NC Sitzungsschicht \NR
\NC Transportschicht \NC[nx=3] TCP \NC[nx=3] UDP \NR
\NC Vermittlungsschicht \NC[nx=3] IPv4 \NC[nx=3] IPv6 \NR
\NC Sicherungsschicht \NC[nx=6] Ethernet \NR
\NC Bitübertragungsschicht \NC[nx=2] 100BASE-TX \NC[nx=2] 100BASE-T \NC[nx=2]
1000BASE-T \NR
\stopxtable
\stoptext
