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_tfplansSDSL_v121(ex.tfplist);    Add to existing tfplist
%   tfplan = getList(ex.tfplist,'ETSI-SDSL-sym-1024'); Get this SDSL plan
