PPCs are required when the TXP, MXP, GE_XP, 10GE_XP, ADM-10G, or ITU-T line card is installed
in a different node than the OCH filter ports. They can also be used to create OTS-to-OTS links between
shelves that do not have OSC connectivity. PPCs are routable and can be used for network topology
discovery by Open Shortest Path First (OSPF). GCCs and DCCs are not required for PPC creation. When
you create a PPC, the PPC Creation wizard asks you to choose one of the following PPC types:
• OCH-Trunk to OCH-Trunk—Creates a PPC between two OCH trunk ports on TXP, MXP, GE_XP,
10GE_XP, ADM_10G, or ITU-T line cards.
• OTS to OTS—Creates a PPC between two OTS ports. This option establishes data communications
network (DCN) connectivity between nodes that do not have OSCM or OSC-CSM cards installed
and therefore do not have OSC connectivity. CTC selects the OTS ports after you choose the
origination and termination sides.
• OCH-Trunk to OCH-Filter—Creates a PPC between a OCH trunk port on a TXP, MXP, GE_XP,
10GE_XP, ADM-10G, or ITU-T line card and an OCH filter port on a multiplexer, demultiplexer,
or wavelength selective switch card.
