Provisionable Patchcords (PPC)
Use the PPC (Provisionable Patchcords) tab to provision a link that is advertised by OSPF throughout the network when a DCC or ITU-T G.709 GCC is not available. 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 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 a 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.
Optical ports have the following requirements when used in a provisionable patchcord:
 •
An optical port connected to transponder/muxponder port, add/drop multiplexer port, or multiplexer/demultiplexer port requires regenerator section DCC/multiplex section DCC (RS-DCC/MS-DCC) termination.
 •
If the optical port is the protection port in a 1+1 group, the working port must have an RS-DCC/MS-DCC termination provisioned.
 •
If the remote end of a patchcord is Y-cable protected or is an add/drop multiplexer or multiplexer/demultiplexer port, an optical port requires two patchcords.
Transponder and muxponder ports have the following requirements when used in a provisionable patchcord:
 •
Two patchcords are required when a transponder/muxponder port is connected to an add/drop multiplexer or multiplexer/demultiplexer port. CTC automatically prompts the user to set up the second patchcord.
 •
If a patchcord is on a client port in a regenerator group, the other end of the patchcord must be on the same node and on a port within the same regenerator group.
 •
A patchcord is allowed on a client port only if the card is in transparent mode.
DWDM cards support provisionable patchcords only on optical channel ports. Each DWDM optical channel port can have only one provisionable patchcord.
 
Item
Description
Origination ID
Displays the originating node patchcord ID (a value from 0 to 32767).
Origination Node
Displays the originating node ID.
Origination Shelf/Slot/Port/ Side
Displays the shelf, slot, port, and side information for the originating end of the patchcord.
Termination ID
Displays the terminating node patchcord ID (a value from 0 to 32767). The origination and termination IDs must be different if the patchcord is set up between two cards on the same node.
Termination Node
Displays the terminating node ID.
Termination Shelf/Slot/Port/Side
Displays the shelf, slot, port, and Side information for the terminating end of the patchcord. The origination port and the termination port must be different.
Create
Displays the Create a Provisionable Patchcord dialog box to create a new patchcord.
Delete
Deletes the highlighted patchcord.
Help
Displays context-sensitive help.
