Using TDM delays are horrid (I remember calls to the US before TAT8 was installed and most calls went via satellite). Geostationary orbit 30K miles (approx), therefore up-leg plus down-leg is 60K miles. Light travels at 186K miles/s, so that's a 1/3 of a second delay in one direction (ignoring any delays through the satelitte to reduce interference etc), so that's 2/3s there and back.
