function tfplist = etsi_tfplansSDSL(tfplist);
%% ===========================================================================
% etsi_tfplansSDSL(tfplist) - Sets up the tfplan for ETSI SDSL
%
% Parameter:    tfplist	   Structure describing the time and freq plan
% Returns:      tfplist		Structure describing the time and freq plan
%
% Example(s):
%   ex.tfplist = etsi_tfplanSDSL(ex.tfplist);    Add to existing tfplist
%   tfplan=getList(ex.tfplist,'SDSL-sym') ;      Get this SDSL plan
%
%   ex.tfplist = etsi_tfplanSDSL([]);            Create a new tfplist
%   tfplan=getList(ex.tfplist,'SDSL-sym');       Get this SDSL plan
