mode” shown in Figure 026-1.
System message “7-C” and “7-D” are displayed in 
succession.
CPU changeover via 
switch (Forced Change-
over)Designate CPU changeover via the “CPU SEL” switch on 
the EMA (PH-PC 40) card.
CPU SEL SW UP Position: No. 0 ACT
CPU SEL SW DOWN Position: No. 1 ACT

TSW changeover via 
switch.On the TSW (PH-SW10) card on which the “TSW 
ACT” lamp is turning ON, flip the “TSW MBR” switch

Perform a Speech Path system changeover test by switch operations. (Refer to Figure 026-4)
TSW changeover via 
switchOn the active GT (PA-GT09) card on which the “OPE/MB” 
lamp is illuminating, flip the “MBR” switch DOWN-UP-
DOWN.
Make sure that the active Speech Path system has been 
changed over to the ST-BY mode. (Check all the related 
circuit cards, which were formerly active, have been totally 
changed over to the ST-BY mode. 
Analyze the system messages “7-E,” “7-F” and “1-T” to be 
displayed automatically.
Perform a PLO system changeover test by switch operations. (Refer to Figure 026-3)
PLO changeover via 
switch.On the PLO card on which the “ACT/OPE” lamp is 
illuminating, flip the “MB” switch DOWN-UP-DOWN.
Note
Make sure that the active PLO system has been changed over 
to the ST-BY mode (“ACT/O PE” lamp goes OFF).
END
Analyze the system messages “7-U” and “7-V” to be 
displayed automatically.
Note:As the PLO, any of the following cards can be used:

Sheet 7/7
System Changeover Test Multiple IMG Configuration
This figure shows a system block diagram centering on the CPU and its controlling GT. Although each side ap-
pears to have complicated connections, the controlling route of CPU 0 goes directly to GT 0, and that of CPU 1
to GT 1. Therefore, if the system of CPU  is once changed over, the ACT/ST-BY of GT is also changed over.

Note:Because the ACT/ST-BY changeover of CPU also affects the GT status, the MBR key on the GT card is
not used for GT system changeover. The key is used to switch over the Speech Path System, involving the
TSW, DLKC, and MUX circuit cards. (See the next page.)
As shown below, though an ex-
ternal cable is physically con-
nected between ISAGT #0 and
GT #1, the actual control signal
is sent/received only between IS-
AGT 0 and GT 0 via the back-
board bus.
