VSC9115
2.5 Gb/s Multi-Service SONET/SDH Mapper Device with Virtual Concatenation
BENEFITS:
Allocated bandwidth for each data channel can be dynamically changed,
without interrupting the traffic, utilizing the Link Capacity Adjustment
Scheme (LCAS) to signal bandwidth changes to the receiving end. This
makes the VSC9115 well suited for carrying multiple varying data flows
from different customers with excellent bandwidth allocation granularity
and efficiency.
Available data channels or payloads can be shared among any number
of the possible maximum 48 transport channels by utilizing contiguous
concatenation and/or Virtual Concatenation at AU-4/TU-3/VC-3,
STS-1/VC-3, or STS-3c/VC-4 levels.
