2.6.9 AU-AIS
An AU AIS condition applies to the administration unit, which consists of the virtual container (VC)
capacity and pointer bytes (H1, H2, and H3) in the SDH frame.
Generally, any AIS is a special SDH signal that communicates to the receiving node when the transmit
node does not send a valid signal. AIS is not considered an error. It is raised by the receiving node on
each input when it detects the AIS instead of a real signal. In most cases when this condition is raised,
an upstream node is raising an alarm to indicate a signal failure; all nodes downstream from it only raise
some type of AIS. This condition clears when you resolved the problem on the upstream node.
