Dual route path protection also allows the XDM-100 to work in conjunction with
other vendors’ SDH/SONET equipment at various transmission rates, regardless of
topology and equipment (see Figure

5.1.2 SubNetwork Connection Protection (SNCP)
SNCP
provides independent trail protection for individual subnetworks connected to
the XDM-100. Combined with the system’s drop-and-continue capability, SNCP is a
powerful defense against multifailure conditions in a mesh topology. By integrating
SNCP into the XDM-100, operators achieve superior traffic availability figures.
Therefore, SNCP is extremely important for leased lines or other traffic requiring
superior Service Level Agreement (SLA) availability.
SNCP switching functions automatically in the XDM-100, without operator
intervention or path redefinition. The result is an exceptionally fast protection
switching of less than 30 ms, with typical switching time taking only a few
milliseconds. Protection switching is performed in a distributed way in the service
cards.
The XDM-100 supports SNCP at all STM-n levels (STM-1 to STM-16) or OC-n
levels (OC-3 to OC-48) and for all VC/STS objects.
