Copying data from all_edges_begin to all_edges_end (or the finite 
version) should allow you to get back the connectivity between points.

If you need to track your original points, use a vertex class such as
Triangulation_vertex_base_with_info_3 and add an integer to each vertex:

(example here 
http://www.cgal.org/Manual/latest/doc_html/cgal_manual/Triangulation_3/Chapter_main.html#Subsection_37.5.2)

and insert your points one by one to set the index associated to each 
vertex.
