Product description
The above mentioned flexibility offers the possibility to create add-drop rings where
the lower-order signals from a VC-4 can be add-dropped, VC-4s can be add-dropped to
the STM-1 tributaries and remaining VC-4s can be passed through. For VC-4
cross-connections to the STM-1 tributaries, one can apply SNC/N protection.
Lower-Order Cross-Connects
The Lower-Order Cross-Connect allows the user to cross-connect any VC-12 or VC-3
from one of the tributary ports to one of the two VC-4s that have been cross-connected
to the LO-CC (see Higher-Order Cross-Connect). For VC-12 and VC-3
cross-connection one can apply SNC/N protection.
