11. MTAS INTEGRATION
MTAS implementation is esentially seamless as far as subscribers are concerned: its services are available for the asking. However the PSTN requires reprogramming to distinguish telephone addresses from device addresses and three transpositionings for address string length recognition. Accordingly, telephone addressing functions separately from MTAS device addressing. This consideration alone permits MTAS implementation without disturbing the present telephone addressing arrangement.

These services can be integrated after MTAS is fully implemented however by appending dummy tones to the telephone address before routing outside the local COX. Of course this operation is invisible to the users.

Now all addresses have the same length and no further transpositions are required. Essentially SS7 routing functions as in present practice.
