							1 GENERAL IMPORTANT! 
1 .Ol This section describes the maintenance pro- 
cedures used to diagnose faults in the STRATA DK 
digital key telephone system. Faults are classified 
and then cleared by replacing the malfunctioning 
unit and performing operational tests in the se- 
quences prescribed by the fault clearing flowcharts 
in Paragraph 5. 
Many system features are assigned, en- 
abled or disabled using software entries 
as described in 
Programming Procedures. 
It is important to verify that the system 
programming is correct and functional 
before troubleshooting the hardware. 
2 FAULT CLASSIFICATION 
2.01 A Fault Classification Flowchart is provided to 
ensure that fault clearing is pursued in a logical 
sequence (Chart No. 1). 3.02 In newsystems, or when the PCTU or PCTUSI 
PCB has been changed, the initialization proce- 
dure must be performed before testing. The system 
data stored on the original PCTU or PCTUSI will be 
protected from loss by the backup battery on that 
PCB. Therefore, the initialization sequence should 
nof be performed if the original PCB is reinstalled. 
NOTE: 
2.02 An assumption is made in the flowcharts that 
the fault was discovered and reported by an elec- 
tronic telephone user. All faults, therefore, are 
classified according to the way they would appear 
at the electronic telephone. 
2.03 Faults and associated flowcharts in Table A 
are organized into the following categories: In this section all information relating to the 
PCTU PCB applies to the PCTlJSl, PCTUl, 
PCTU2, and PCTU3 unless otherwise stated. 
1 
3.03 Faults in the system are cleared by replacing 
PCBs, electronic telephones or the power supply, 
as instructed in the flowcharts.

that it is in the system and not caused by associated 
external equipment, such as wiring, MOH source, 
etc.

3.05 The flowcharts are sequentially arranged to 
permit rapid fault localization within the system. 
All 
fault clearing must begin with the Fault Classifica- 
tion Flowchart, which is arranged in the correct fault 
locating sequence. 
3.06 The following precautions must be observed 
when handling PCBs: 
DO NOT: 
l Drop a PCB. 
l Stack one PCB on top of another. 
l Handle a PCB without discharging any static 
electricity from your person by touching the 
grounded cabinet. 
0 Touch PCB contacts with your fingers. 
IMPORTANT! 
If the fault is not cleared by substituting a 
PCB, the original PCB must be reinstalled 
in the cabinet before trying another PCB. 
4 DEFECTIVE APPARATUS RETURNS 
4.01 When adefective system apparatus is shipped 
for repair, the apparatus must be packed in a 
suitable container (the original box is highly recom- 
mended), as follows: c) Plastic bags for electronic telephones, KSU, 
etc. 
. 
4.02 NEVER WRITE ON THE APPARATUS IT- 
SELF! Describe the nature of the defect on an 
information tag. Attach the tag to the front of the unit 
with string (not wire) so the tag can remain attached 
during the testing and repair process. Return tags 
are available from Toshiba America Information 
Systems, Inc., TSD Division. 
4.03 If different and/or additional faults are created 
in the system by substituting a PCB, tag and return 
the substitute PCB as a defective unit. 
5 FAULT IDENTIFICATION and 
ELIMINATION PROCEDURES 
5.01 The PCTU PCB may contain a “soft” fault due 
to static electricity. If it is found defective during the 
fault finding procedures, attempt to clear a soft fault 
prior to returning the PCTU PCB for repair. The 
correct procedure for this is to reinstall the PCTU, 
perform the initialization procedure, and then re- 
program the system as necessary to test for the 
fault. If the fault returns after these procedures are 
performed, tag the defective PCTU and return it for 
repair. 
6 POWER SUPPLY 
a) Paper container for the PCTU PCB. 
b) Anti-static containers for all other PCBs. 6.01 If a DC power fault is detected, all PCBs 
should be disconnected from the backplane con- 
nectars to eliminate them as the cause of the power

problem. The Power Supply Test Procedure in 
Paragraph 3, Section 200-096-205, Installation, can 
be employed to further isolate possible causes 
before removal of the KSU back cover or the power 
supply unit. Figure 2 shows backplane connector 
Pl and P4 and voltages at each pin. Voltages 
should fall within the following ranges: 
Nominal Range 
-24V -26.3 - -27.8 
+5v +4.5 - +5.5 
-5v -4.5 - -5.5 
6.02 If voltage checks indicate a power supply 
fault, replace the power supply with a correctly 
operating unit. Refer to Section 200-096-200, In- 
stallation, for power supply installation procedures.

HKSU and the electronic telephone is checked with 
a voltmeter as follows: 
NOTE: 
Perform the following at the locations indi- 
ca ted: 
I. Modular block: Check all station cables. 
2. MDF: Check cable from KSU to MDF. 
1) Disconnect the electronic telephone. 
2) Using a DC voltmeter, measure between the 
wires of the two pairs to verify the readings 
shown in Table E (Refer to Table G on page 
27 for a PDKU). 
I 
3) An improper reading indicates an open, 
crossed or shorted wire. 
4) For the MDF-to-electronic telephone cable, a 
more precise check is made using an ohm- 
meter.
