Loss of Sync Word—The HDSL4 loop has lost synchronization.

MAL

xxxx-MALx

Margin—The margin on the HDSL4 loop has dropped below the minimum threshold

 

 

value set for the system.

 

 

xxxx denotes TUC, TUR, or first (DU1U/DU1D) or second (DU2U/DU2D) doubler HDSL4

 

 

upstream or downstream interface. If TUC and TUR occur at the same time, then TUC

 

 

displays. The single x indicates Loop 1 or Loop 2.

LA
