Main benefits
♦ Dedicated performance monitoring-based
protection for any VC-12/3/4 or E1/DS-3/STS-
3c and concatenated traffic
♦ Better service reliability
♦ Better reliability and network resilience as the
XDM-100 handles multiple failures over mesh
topologies
♦ Better bandwidth utilization in case of uniform
or adjacent traffic patterns
♦ Multiring closure within the same XDM-100
(path protection, MS-SPRing/BLSR and UPSR)
in mesh topologies, together with low-order E1
connectivity, improve network efficiency and
reduce floorspace and costs compared to
common protection schemes
♦ Bandwidth efficiency
Main benefits
♦ Better service availability and reliability
♦ Optimum equipment flexibility for all services
♦ Better service availability and reliability
♦ Optimum equipment flexibility enables
MSP/APS protection in addition to other
protection schemes
♦ Better service availability and reliability
♦ Optimum equipment flexibility for all services
