General
This document is to be used by service personnel when maintaining the
IP phones DBC 433 01 (Aastra 7433ip), DBC 434 01 (Aastra 7434ip),
DBC 444 01 (Aastra 7444ip), and DBC 446 01 (Aastra 7446ip).
Hardware faults in DBC 43x or DBC 44x should not be
repaired locally, except for replacement of parts listed in
the ordering information for Telephones and Peripheral
Equipment. The purpose of the following instructions is to
decide whether there is a hardware fault in the IP phone
or not.
If a hardware fault occurs in DBC 43x or DBC 44x, the
unit should be returned to Aastra Global Service
Logistics Centre.
If there is a fault in the software of the phone, the software can be
updated on site, see Installation Instructions for DBC 433, DBC 434, and
DBC 444.
For information about spare parts, see Ordering information for Telephones and Peripheral Equipment.

DBC 433, DBC 434, and DBC 444
It is possible to restart the phone manually by pressing and holding the
key
until the dialog message Restart the phone? is displayed,
and then pressing Yes. This is called a software restart.
Note: If a lock up problem is to be isolated, it is useful to enter the SSH
command showLog, see section 4.1.3.3 Print Recent Events on
page 11. The log will be kept after the software restart.

IP PHONES DBC 43X AND DBC 44X
If the software restart does not restart the phone, perform a power
restart.
•
For DBC 434 and DBC 444, switch off the power by pressing and
holding
for a couple of seconds.
•
For DBC 433, switch off the power by disconnecting the phone from
the power supply and then reconnecting it.
When a power restart is performed using any of the methods above, the
log file initiated by ShowLog is lost. The log initiated by ShowFlashLog
is available after power restart. See 4.1.3.4 Print Events From the Flash
Memory on page 11.
3.2
DBC 446
It is possible to restart the phone manually by pressing the keys C
(Clear key), # and mute simultaneously for 1 second. This is called a
software restart.
Note: If a lock up problem is to be isolated, it is useful to enter the SSH
command showLog, see 4.1.3.3 Print Recent Events on page 11.
The log will be kept after the software restart.
If the software restart does not restart the phone, perform a power
restart.
•
To keep the log after restart, restart the phone with the reset button.
The reset button is located at the back of the phone, just above the
connectors. Press the reset button by inserting a thin object, such
as a screwdriver, into one of the hollows for the foot consoles, see
1 Position of reset button on the DBC 446 phones on page 8. This
is called a hardware restart.
•

Commands
To view a list with the available commands and their explanation, enter
the command Help.
4.1.3
Event Logs
It is possible to obtain a log file of events, which are printed from either
the application software or the operating system, see below.
•
From the application software. The events are printed from
different modules in the application.
•
From the operating system. The events are stored in the run-time
error record log, and in the post-mortem event log.
The log file can be attached to a fault report, and it can be analyzed by
the level three support. The log should not be interpreted by maintenance personnel.
It is possible to select the level of events from the different parts of the
software in the phone.
setWAPDebugLevel 0-4
The events that occur in the WAP module in the phone. This
module handles services and display messages. This command is
only valid when the gatekeeper supports WAP.
setUIDebugLevel 0-4
The events that occur in the user interface module in the phone.
setH323DebugLevel 0-4
The events that occur in the H.323 stack module in the phone.
setRTPDebugLevel 0-3
The events that occur in the voice (media stream) module in the
phone.
setWEBDebugLevel 0-3
The events that occur in the web server.
setOMDDebugLevel 0-3
The events that occur in OMD mode.
Typically, the levels of stored events have he following meaning:
0 = No events are printed, 1 = Messages that most likely are errors are
printed, 2 = Major events are printed, 3 = Minor and major events are
printed, 4 = All events are printed.
For a detailed description, enter the command Help.
These commands work through the web server interface as well.

Print the Phone’s IP Addresses And Status
To print the IP addresses and the status for the phone, enter the
following command:
phoneStatShow
4.1.3.2
View Events As They Occur
Log on via SSH as described above. The events are displayed as they
occur in the phone.
4.1.3.3
Print Recent Events
It is possible to retrieve the most recent events in the phone. These can
be events that occurred before logging on to the phone with SSH. The
event log offers 4000 lines and is obtained by opening a log file in the
PC, logging on the phone and entering the following SSH command:
showLog
The log is kept even when the phone is restarted, but is lost after a power
loss. The command works through the web server as well, see Section
4.2.2 Use the Functions In the Web Interface on page 14.
4.1.3.4
Print Events From the Flash Memory
The watchdog function (see Section 7 Watchdog on page 18) can store
the last events in the flash memory before the phone is restarted. The
command for printing the log from the flash memory is
showFlashLog
Data in this log is available even after power restart or failure.
The log is overwritten next time the watchdog is activated.
4.1.3.5
Run-time Error Record Log
This log shows the run-time error records (up to the last 7) detected by
the operating system. The log is cleared at power restart. Examples of
recorded events are bound-check errors, violations of memory blocks
and pointer arithmetic errors. The command for printing the log is
edrShow
4.1.3.6
Post-mortem Event Log
This log contains the function calls to the operating system in the phone.
In this log it is possible to analyze all operating systems calls from the
11

LOG ON TO THE IP PHONE FROM A PC
application before a crash occurred in the phone. This log is saved even
after a restart of the phone, but not after power loss.
Log on to the phone as described in section above. Start the
post-mortem log by entering the following SSH command:
startEventLog
After this it is possible to log off and wait until the problem in the phone
occurs. To up-load the post-mortem log to the PC:
1.
