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.

|
Displays the originating node patchcord ID (a value from 0 to 32767).
|
|
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.
|
|
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.
|
|
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.
|
|
Displays the Create a Provisionable Patchcord dialog box to create a new patchcord.
|
|
Deletes the highlighted patchcord.

|
Displays context-sensitive help.
