RAPs over EOS (Ethernet over SONET)

I just turned up a Ciena 3930 over EOS and the ring went into OK state as soon as the interfaces facing a Fuji 4100 went up/up. The SONET path wasn’t finished and the RPL went into blocking after the 60 second WTR kicked in. This leads me to believe that if we were to take a fiber cut on the EOS path the switch wouldn’t realize the ring is broken due to the interfaces not actually going down. I remember there being a OAM type config that would send checks along the path and if a few frames were lost it would consider the link down and switch. Any ideas?
