When an ML-series RPR ring is provisioned over a SONET BLSR (or SDH MS-SPR) ring, the ML architecture can no longer utilize the full available bandwidth on the SONET/SDH ring due to the constraints of BLSR. Which features are being introduced to allow use of discontiguous timeslots and BLSR protect channels when provisioning ML-series RPR rings, in order to alleviate this limitation?
