Atm Sdh
Anyone can draw up to me the SONET / SDH ATM network for carrying PDH signals and data signal line
The entire system is ATM and the carrier is SDH / SONET ...
SONET / SDH does not ride ATM, ATM sonet is how, in the sense that it is a layer two (data link) technology. PDH was (or has been) replaced by SDH wikipedia .. go read up on two different technologies ..
