Station to Station Connection Test
START
Confirm that a connection can be established between Station “A” and Station “B.”
Station “A” goes off-hook.
Station “A” hears dial tone.
Station “A” dials the station number of Station “B.”
Station “A” confirms that dial tone stops when the first digit has been dialed.
Station “A” confirms that ringback tone is heard after dialing ends.
Station “B” hears ringing on the telephone set.
Station “B” lifts handset and answers the call.
After answering, both Stations “A” and “B” confirm that they can talk with 
each other.
Stations “A” and “B” hang up. The connection is released.

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.”

via MBR key on the CPR 
DSP (PZ-DK224) On the CPR DSP on which CPU OPE lamp is illuminating, flip the 
MBR key DOWN → UP → DOWN (OFF → ON → OFF).
Lamp indication on the DSP changes to “DSP in ST-BY mode” as 
shown in Figure 025-1.

Control System changeover 
via CPU SEL key on the 
EMA card. (Forced 
Changeover). Designate CPU changeover via CPU SEL key on the EMA (PH-
PC40) card.
 CPU SEL key=UP:  CPU of No. 0 system goes active (ACT)
 CPU SEL key=DOWN:  CPU of No. 1 system goes active (ACT)
Confirm the changed lamp indications on both DSP in ACT/ST-BY 
mode as shown in Figure 025-1.

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.

→ ON → OFF).
Make sure that the ACT/ST-BY of all Speech Path Systems in LN0/1/2/3 are totally changed 
over (Refer to Figures 025-3 and 025-7).

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 CMODI/CMOD command. Refer to the “System Operations
and Maintenance Manual.”

(OFF → ON → OFF).
Make sure that the ACT/ST-BY of all Speech Path Systems (in ISW and each Local Node) 
are totally changed over (Refer to Figures 025-3, 025-5, 025-6 and 025-7).
