can you try the following configuration:

controller SONET0/3/0/0/1
     overhead s1s0

More information about the sonet controller configuration can be found at the following URL:

The problem was solved by changing framming type,as by defaut it is sonet we required to change it to SDH.some of the mux have compatibility problem with routers ports, other wise this things can be auto detected.
