22.3 Provisionable Patchcords
A provisionable patchcord is a user-provisioned link that is advertised by OSPF throughout the network.
Provisionable patchcords, also called virtual links, are needed in the following situations:
• An optical port is connected to a transponder or muxponder client port provisioned in transparent
mode.
• An optical ITU port is connected to a DWDM optical channel card.
• Two transponder or muxponder trunk ports are connected to a DWDM optical channel card and the
generic control channel (GCC) is carried transparently through the ring.
• Transponder or muxponder client and trunk ports are in a regenerator group, the cards are in
transparent mode, and DCC/GCC termination is not available.
Provisionable patchcords are required on both ends of a physical link. The provisioning at each end
includes a local patchcord ID, slot/port information, remote IP address, and remote patchcord ID.
Patchcords appear as dashed lines in CTC network view.
Table 22-5 lists the supported card combinations for client and trunk ports in a provisionable patchcord.
