LMP > Data Links
(ONS 15454 SDH only) Use the LMP > Data Links subtab to define the node’s transport parameters. CTC supports up to 256 LMP data links. For information about creating, editing, or deleting LMP Data Links see:
LMP > Data Link > Create LMP Data Link Dialog Box

Item
Description
Operational State
Displays the state of LMP operation. The state of an LMP data link is derived from the service state of the client port with which it is associated. A service state of unlocked is mapped to the data link state of Up. Any other service states are mapped as Down:
 •
Unknown—Indicates that LMP is not enabled.
 •
Up—Indicates that LMP is enabled and the link is active.
 •
Up-Alloc—The Up-Alloc data link is allocated for data traffic.
 •
Up-Free—The Up-Free data link is not allocated for traffic. The remote node is either not ready to receive traffic through this port, or the path is being used as a backup in case some other allocated data link goes down.
 •
Down—Indicates that LMP is enabled and the link is inactive.
Tips: If data link state does not transition to Up-Alloc or Up-Free:
 •
Check that the port is in-service. This has to be done from the port provisioning tabs. The data link will be in the Down state if the port is not unlocked. Changing the state of the port will impact the state of a data link using the port.
 •
Check that you are using the correct Remote Port ID for the far end data link.
 •
On the remote node, check that the data link is using the Local Port ID as the Remote Port ID.
Local Port
Displays the Slot # and Port # selected from the drop-down list in the Create LMP Control Channel dialog box.
Local Port Id
Displays the local port identifier assigned by the node.
Data Link Type
Displays either Port or Component, which can be chosen in the Create LMP Data Link dialog box.
A data link is considered as either a port link or a component link by each node that it terminates on, depending on the multiplexing capability of the endpoint on that link. Component links are multiplex capable. Ports are not multiplex capable.
Local TE Link Id
Displays the local TE link identifier.
Remote Port Id
Displays the remote port identifier.
Create
Displays the Create LMP Data Links dialog box. See LMP > Data Link > Create LMP Data Link Dialog Box for field descriptions.
Edit
Displays the Edit LMP Data Links dialog box. See LMP > Data Link > Edit LMP Data Link Dialog Box for field descriptions.
Delete
Displays the Delete LMP Data Links dialog box. See LMP > Data Link > Delete LMP Data Link Dialog Box for field descriptions.
Help
Displays context-sensitive help.
