1.00 INTRODUCTION 
1.01 General 
The Online Monitor (ONMN) feature of the MPK 
system allows the display and alteration of the 
system memory. This feature is intended for the 
advanced installer or engineer, when debugging 
and maintaining the MPK system. It is not intended 
for customer usage. 
CA UT/ON: Indiscriminate use of the Online Monitor 
can cause data base errors and system 
execution errors resulting in the need 
for reprogramming of the data base or a 
system reset. The Online Monitor can- 
not cause permanent system or hard- 
ware damage. 
1.02 Description 
With the ONMN routine, you can monitor the MPK 
system, as well as change its state by altering 
memory storage locations. These memory storage 
locations include the control block contents, which 
are described in Section 3.00. The ONMN routine 
displays the contents of these control blocks and 
allows altering of bytes with the use of ONMN 
commands. 
2.00 COMMANDS 
To use the Online Monitor, type ONMN and press 
the carriage return. The following is a list of com- 
mands which may now be used after the character- 
istic # (pound) prompt. Be sure to press the carriage 
return (where indicated by the symbol ) 
after typing each command. 2.01 Memory Display M  
Typing M, a hexadecimal memory address in 
upper case and a carriage return, displays the 16- 
byte area of memory starting at that memory address. 
The cursor remains at the end of the line, awaiting 
any of the following: 
 -Pressing thecarriage return dis- 
plays the next 16-byte block of 
memory. 
  -Pressing a backslash and a car- 
riage return displays the pre- 
vious 16 bytes of memory. 
CTRL X -Pressing X while holding down 
the CTRL.key redisplays the cur- 
rent 16 bytes of memory. 
Any Other 
-Entering any other ONMN 
ONMN Command 
command (such as change, 
Quit or Control Block Display)’ 
will perform the functions indi- 
cated in the following sections. 
2.02 Change C  
Typing C, a space, a hexadecimal memory address 
(xxxx) in upper case and a carriage return displays 
the contents of memory at that address. The system 
then waits for any of the following to be typed: 
0 to FF  -Entering a hexadecimal value 
from 0 to FF followed by a 
carriage return writes that value 
in memory at the specified 
address. The system then 
verifies that the new value is 
written in the correct location 
and, if true, displays the next 
memory location. Otherwise, 
the system displays the mes- 
sage, “WHAT?” and the value 
of the memory location.

-Pressing a period and the car- 
riage return ends the change 
feature. The number of control blocks available varies with 
the type of control block. Values requested outside 
of the actual range of the number available for that 
type of control block default to the first block of that 
type. 
2.03 Quit Q  
Examples: 
Pressing Q and the carriage return exits the On- 
line Monitor. The monitor does not time out; only the 
Quit command exits the monitor properly to permit, 
for example, removal of the display device. S or Sl or S 1 -Displays the control block for the 
first station 
Typing the entire word QUIT followed by a carriage 
return exits the Online Monitor and the terminal 
display mode so that the SMDR printout may continue. SlOor S 10 -Displays the control block for 
the first station 
2.04 Control Block Display x nn  
Control blocks are areas in memory which contain 
formatted information useful for controlling certain 
system functions. Typing the designator letter (x) 
for the type of control block, any allowed number 
value (nn) for that type of control block (see Figure 
5-l), and then pressing the carriage return, displays 
the control block in the following form: S41 or S 41 -Displays the last station 
S99 or S 99 -Displays the first station 
After displaying the requested control ‘block, the 
system waits for a memory display command, a 
change command, a quit command or any of the 
following: 
 -Entering a carriage return dis- 
plays the next block of the current 
type 
BB AAAA DDDDDDDDDDDDDDDDDDDDDDDD 
DDDDDDDDDDDDDDDDDD 
WHERE:   
-Entering a backslash and a car- 
riage return displays the preced- 
ing control block of thesame type 
BB is the hexadecimal number of the 
requested block 
AAAA is the hexadecimal RAM address of 
the start of the requested block 
DDD..D is the contents of the control block in 
hexadecimal. Two characters are dis- 
played for each hexadecimal data 
byte in the block. CTRL X -Pressing X while holding down 
the CTRL key redisplays the cur- 
rent block 
3.00 CONTROL BLOCK FORMATS 
The following figures list the control block formats 
and definitions.

1.00 INTRODUCTION 
1.01 General 
This section describes the troubleshooting pro- 
cedures that should be followed in the event of 
system malfunction. System troubleshooting and 
repair will be confined to module replacement (e.g., 
printed circuit board, power supply, keyset, etc.). 
Repair beyond module replacement is not within the 
scope of this manual. 
2.00 DEFECTIVE UNIT RETURN POLICY 
2.01 Return Authorization Tags 
To return a unit, obtain a Return Authorization Tag 
and attach it to the defective unit. Proper docu- 
mentation of the Return Authorization Tag will 
ensure the rapid repair and return of the equipment. 
Adhere to the following guidelines when filling out a 
Return Authorization Tag: 
NOTE: INTER-TEL does not accept fhe return of 
defective units without return aufhorizafion 
fags. 
A. Obtain a repair authorization number from the 
INTER-TEL Return Authorization Department. 
B. Identify the unit by the equipment name, part 
number, and serial number. 
C. Describe the defect and, if applicable, the circuit 
number related to the defect. 
D. Document the estimated service time prior to 
failure. 
E. Attach the upper portion of the tag to the defective equipment. Retain the bottom portion 
for your files. 
3.00 TROUBLESHOOTING PROCEDURE 
3.01 Preliminary Troubleshooting Checklist 
Before starting the system troubleshooting pro- 
cedures, complete the following checklist. This 
check list may save your time and possibly eliminate 
the need for detailed troubleshooting. 
CHECKLIST: 
A. 
B. 
C. 
D. 
E. 
F. Verify that the problem is not related to user 
error or equipment that has been disconnected 
or disabled. 
If the defect is related to an optional feature, 
make sure that the option has been enabled. 
Check that all printed circuit boards and equip- 
ment cables are securely seated or connected. 
Check all LED’s for proper indication. See 
Section 3.03, Light-Emitting Diode Indications, 
for proper indications. 
If any optional external equipment (e.g., 
autodialers, headsets, loud ringing adapter, etc.) 
is connected to the system, verify.that this 
equipment is not responsible for the problem. 
Each multi-line keyset contains a micro- 
processor that is essential to the functions of 
the keyset. The supply voltage to the micro- 
processor is CRITICAL and must be set at the 
correct voltage level to ensure proper operation 
of the phone set. For correct voltage adjust- 
ment, refer to the installation section of this 
manual (340-l 00-300; 1.05). 
If the problem is still present after completing the 
Preliminary Troubleshooting Checklist, proceed to 
Section 3.02, 
“Detailed System Troubleshooting 
Procedures.” 
3.02 System Troubleshooting Procedures 
This portion of the troubleshooting procedures is 
designed to assist the technician in the event of an 
equipment failure. The troubleshooting procedures 
have been divided into four separate categories: 
Page 6-1  
						

							TROUBLESHOOTING 
SECTION 340-100-600 
issue 3, April 1983 INTER-TEL PRACTICES 
feature failure, internal communications, external 
communications, and system malfunctions. 
The troubleshooting charts in this section list the 
symptom, the possible cause, and the corrective 
action for the symptom. After locating the symptom 
listing which corresponds to the problem being 
experienced within the system, perform the cor- 
rective action steps in the order indicated in the 
procedures. If the problem is not corrected by 
following the procedure, contact INTER-TEL’s Field 
Service for assistance. 
A. Feature Failure. Before starting this trouble- 
shooting procedure, refer to Section 340-100- 
200, Features, and perform the function which is 
reported to be defective. This is to ensure that 
the trouble is not the result of misoperation of 
the keyset by the user. Once proper operation is 
confirmed, remove the keypad portion of the 
keyset. Examine the contacts under the feature 
button for dirt or dust and clean if necessary. If 
proper feature operation is still not possible, 
proceed to the FEATURE FAILURE TROUBLE- 
SHOOTING CHART, Figure 6-l. 
B. Internal Communications. This portion of the 
troubleshooting section deals with internal calls 
only. Refer to Figure 6-2, INTERNAL COMMUN- 
ICATIONS TROUBLESHOOTING CHART. 
C. External Communications. This portion of the 
troubleshooting section deals with external 
calls only. Refer to Figure 6-3, EXTERNAL 
COMMUNICATIONS TROUBLESHOOTING 
CHART. 
D. System Malfunctions. This portion of the trouble- 
shooting section is designed to isolate a mal- 
function which appears throughout the system. 
Refer to Figure 6-4, SYSTEM MALFUNCTIONS 
TROUBLESHOOTING CHART. 3.03 Light-Emitting Diode! Indications (LED) 
Each board in the INTER-TEL MPK system contains 
light-emitting diodes (LED’s). These LED’s will 
indicate specific functions related to that board. 
Figure 6-5 indicates the normal status of the LED’s 
when the MPK is operating. If the LED’s are not as 
stated, perform the troubleshooting procedures as 
described in Sections 3.028, 3.02C, or 3.02D when 
the problem involves a specific circuit or circuits. If 
the power reset LED will not illuminate and 
extinguish after a reset condition or power up, 
remove that PCB, wait 10 seconds, and re-insert the 
PCB. If power interrupt indications are still incor- 
rect, replace that PCB with a known good PCB. If the 
NMI LED is illuminated on the CPU, reset the system 
by momentarily placing SW2 of the CPU PCB in the 
ON position. 
NOTE: Use of the reset (REST) function will 
disconnect any calls in progress. If the NM/ 
LED is illuminated frequently, contact 
INTER-TEL’s Field Service for assistance. 
If the first three LED’s on the CPU are not 
flashing at their respective rates (refer to 
Set tion 340- 7 00-300 for proper flash rates), 
check the +5VDC on the KSU power supply 
and adjust if necessary. After checking the 
voltage and making any necessary adjust- 
ments, turn the system power off, wait for 70 
seconds, and re-apply system power. If 
problem still exists, contact INTER-TEL’s 
Field Service for assistance. 
NOTE: The following symptoms are isolated to one 
keyset only. For identical problems involving 
more than one keyset, refer to para. 3.02; D 
SYSTEM MALFUNCTIONS.
