3.1 Outline
Tests are to be performed on the restart processing (reinitialization) and system changeover functions which en-
able the system to restart its operations and services.
3.2 System Initialized Test Procedure
The System Changeover Test and Initialization Tests are to be performed per the NAP Numbers indicated to the
right of each item in the following flowchart.

Test Outline
Tests are to be performed to see if the ACT/ST-BY of the following equipment is normally changed over:
1. Control Systems in each Local Node (LN)
2. Control Systems in ISW
3. Speech Path Systems in each LN (TSWM0/TSWM1)
4. Speech Path Systems in ISW + all LNs as a whole

1. Control System changeover in each LN
Follow the procedures below to perform the Control System changeover tests in each Local Node (LN). This
test must be performed in each LN independently:
Note:This changeover can also be performed via the CMODI/CMOD command. Refer to the “System Operations
and Maintenance Manual.”

3. Speech Path System changeover in each ISW
Follow the procedures below to perform the Speech Path System changeover tests in ISW:
Note:This changeover can also be performed via the CMODI/CMOD command. Refer to the “System Operations
and Maintenance Manual.”
Note:If you change over from LNs, the entire system will be changed over. Therefore, it is best to change over
from ISW.

4. Total Speech Path System changeover
Perform the total Speech Path System changeover test by referring to the flowchart below. As suggested in the 
previous page, the ACT/ST-BY of Speech Path Systems can be differently set in every Local Node (LN). How-
ever, excepting a particular case, the Speech Path changeover is normally performed on a system basis as shown
in this page:
Note:This changeover can also be performed via the...

Change over the ACT/ST-BY of the PLO systems in each LN via key operation.
On the active PLO (PH-CK16-A) card in TSWM0, flip the MB key DOWN →  UP →  DOWN 
(OFF → ON → OFF).
Make sure that the ACT/ST-BY of the whole PLO systems (PLO in TSWM0 and CLK in 
TSWM1) in the same Local Node (LN) are totally...
