and the Station Line Status Display features, which are displayed on the MAT or the CAT, and
restore the fault.
FAULT MESSAGE
Item (1) shows the display format for the Fault Message feature, and item (2) shows the fault di-
agnosis and troubleshooting method. For details of the Fault Message feature, see Fault Mes-
