Currently, the only way of doing this is the "traditional way" of using SONET add-drop muxes to get you up to higher rates. You mux the STS-3c into an STS-12 and then mux the 12's into a STS-48. This is what we are doing in ATDNet which is a ATM OC-48 bidirectional line-switched ring for ARPA
and DoD.
(see http://www.atd.net/atdnet.html).
As per our previous discussion, the trend seems to be putting the switching and transport functions in one box so that you may be able to buy an ATM switch that also does SONET protection switching.
I fail understand, however, why ATM over SONET is desirable when there is such a loss to overhead, especially when viable alternatives may exist to get more bang-for-the-buck. Perhaps someone could enlighten me on this particular datapoint? - paul
