Note 1: The circuit cards, drawn by dotted lines, indicate they are in STBY state. These cards (TSW, MUX and DLKC) are totally changed over to the ACT mode, when the MBR key of the active GT (PH-GT09) card is once flipped. However, PLO (PH-CK16/17/16-A/17-A) is independent and not affected by the development.

Note 2: If the ACT/STBY of CPU is once changed over, the system of GT (in TSWM) also changes over.

Note 3: Though an external cable is physically connected between ISAGT0 and GT1, the actual control signal is sent/received only between ISAGT0 and GT0. This is because GT0 and GT1 are having a multiple connection on the backboard side. (Refer to Chapter 6, Section 12.)
