LSSU Link Status Signalling Unit
The Link Status Signalling Unit is sent between two SS7 signalling points and serves to indicate the status of the specific link. When a link is determined to have failed the signalling point that detected the error condition is responsible for alerting adjacent signalling points that the link is not available. The LSSU is used to perform this task.
