If you are using only the RDTU for dial tones and have no other RCOU/RCOS or RDDU or RGLU cards, the dial tone numbers would not shift.

If you moved the RDTU to a second cabinet and had any other dial tone cards follow in the same order, the DT numbers would not change. You do have to do all the programming for that slot (timing, etc.) but it should work fine.
