Sorry, I was backwards on the RDSU1, ports 008-011 are the POTS extensions and 012-015 are the DKT extensions, so extension 213 ring assignments should be possable with program 8x port 013 - remember when using program 39 and 81 etc you need to enter the port number (000 - 015) not the extension number (200-215).
Probably not necessary on your small system, but on a larger system where extensions have been remapped from the default port-to-extension mapping it helps to plug a display phone into the jack and dial intercom #402 to display the actual port number.
