Matrix Connections (MC)
A TDM cross-connection is created between two connection termination points (TP), where the starting point is the A-End TP and the ending is the Z-End TP.
Matrix Connection at P0_nc level
The TPs can be connected with each other inside a NE through Matrix Connections (MC). The MCs are named as cross-connections in the FOX51x and FOX61x documentations.
A pair of TPs can be connected if:
• neither is already part of a connection,
• both TPs are of the same bandwidth (layer, e.g. P0_nc).
The MC has three TPs: Working (AWork), AProtecting (AProt) and Output (Z) that are TPs of the same layer rate. The MC itself can be configured in protected mode.
If the MC is not protected only the A Work and Z TP are used.
