1 Introduction
This
document specifies the features of 61xx series Field Test Display.
Field
Test Display, i.e. engineering test mode, is a configurable software
feature
which is available through MMI menu.
Field
Test Display is useful for testing mobile phones during development
or
for verifying the operation of the network.

2 Using the Field Test Display
When
the Field Test Display is active, the phone works in a similar way as
without
it, except that the arrow buttons (^,v) scroll through the various
tests,
whereas they would scroll through the memory locations while the
Field
Test Display is inactive. The test numbers that are not valid are
not
scrolled.
The
Field Test Display appears as a so called soft indicator, which means
that
it is visible only if there is nothing else to display. For example,
once
the first digit of a phone number has been dialled, the Field Test
Display
disappears and the digit appears. After the whole number has been
dialled
and a call setup has started, the number disappears and the Field
Test
Display reverts.
When
the Field Test Display is active and mobile originated call setup is
going,
'CALLING XXXXX' text is not shown. However, if some call divert is
active,
'note diverts' text is viewed. When keyguard is active, keyguard
texts
(or icons) are disabled and Field Test Display is visible. Pressing
a
key views normal keyguard texts. When user activates the keyguard,
keyguard
note is shown shortly.
During
proper power off (use of power key or RE-CHARGE indication)
some
valuable data (e.g. the number of current field test display) is
stored
onto the EEPROM. Next time when the phone is powered on the lastly
selected
field test display will be automatically re-activated.
2.1 Activating the Field Test Display
The
Field Test Display is located at the end of the main menu loop. It is
activated
as follows:
- press the Menu button
- scroll in the main menu loop to field test display item
(NETWORK MONITOR)
- press the Select button
- enter the index number of the test to be activated at the
TEST NUMBER prompt
- confirm with the Ok button
The
field test data will then appear in a moment. The index number of the
test
will appear in the top right corner of the display. If given test
number
is not valid "No Test" -text will appear to the display.
A
quicker way to activate the Field Test Display is to use the menu
shortcut.
The field test display is the last item in the main menu loop.
The
shortcut activation of the field test display is done in the following
way:
MENU <number of the last item> <number of the desired field test display>
If
the last number of the main menu loop is e.g. 8, in order to activate
test
display number 20, just press Menu, 8, 20 and Ok in a sequence.
See
chapter 2.5 for recommendations.
2.2 Deactivating the Field Test Display
The Field Test Display is deactivated as follows:
- press the Menu button
- scroll in the main menu loop to field test display item
- press the Select button
- enter 0 at the TEST NUMBER prompt
- confirm with the Ok button
2.3 Field test modes
There are three Field Test Display modes:
- execute mode
- data display mode
- help mode
Different
modes are marked in this specification as follows:
************** ++++++++++++++
##############
* *
+ +
# #
* Execute *
+Data display+ #
Help #
* Mode *
+ Mode +
# Mode #
* *
+ +
# #
************** ++++++++++++++
##############
The
execute mode is entered from the menu as described in 2.1 (either
scroll
and select or shortcut). If the test index entered pertains to a
test
that resets a timer (test 80) for example, then the timer is reset
as
soon as the Ok button has been pressed in the menu, and the data
display
mode takes over. In other words, the execute mode is of the
one-shot
type. To run another test in the execute mode, the Field Test
Display
menu must be re-activated.
During
the data display mode, the field test data (e.g. carrier, power
level,
cell) is visible on the main display. During the help mode, one
screen
of instructions is shown for each test to make it easier to identify
the
test in question. A long press of asterisk (*) is used to toggle
between
these two modes.
The
arrow keys (^,v) offer an easy way to switch to another test without
using
the menu. However, the data display mode remains, i.e. nothing will
be
executed or set on although such tests would be passed. This is to
prevent
the user from accidentally clearing any valuable data. (see 3.7.2
for
details and 2.5 for recommendations).
The
help mode is also a non-execute mode. Display numbers have been selected
in
such way that no 5-terminated test number is an execute display.
2.4 Signal and battery levels
When
Field Test Display is active, normal signal and battery level
bars
are visible.
2.5 Reserving SIM SCM locations (recommendations)
When
starting to use a SIM-card in a phone with field test displays, it is
recommended
to put some default data into SIM SCM locations that are used
by
field test displays. This prevents accidental storing of phone numbers
and
names into such locations.
SIM
SCM Recommended Recommended

number text (name)

--------------------------------------------------------

0 BTS TEST
17
Reserving
SIM SCM locations is not necessary if the user is sure that
he/she
will never select these displays using menu shortcut (which
executes
the display).
In
61xx series (DCT3) phones it is not possible to select the SIM
location
number where the number and the name will be stored.
So,
reserving a SIM location must be done by some PC software or,
for
example, by 8110i (DCT2) phone.
3 Information on the displays
Length
of a field is shown in the display picture by amount of the letters.
If
a value is not available, 'x' is shown for all the digits. If data to
be
displayed is shorter than the field reserved to show that data, text
is
aligned left and numbers right.
3.1 Signalling displays, which can be visible to network operators
Those
signalling displays which can be activated by the network operators
are
numbered from 1 to 19. Before field test displays are visible, mobile
has
to be modified. With the normal production mobile field test
displays
are not working.

1 (01) The MS shall report the strongest cell, with known and allowed
NCC part of BSIC, in each of the frequency bands in the BA
list, excluding the frequency band of the serving cell.
The remaining positions in the measurement report shall be used
for reporting of cells in the band of the serving cell.
If there are still remaining positions, these shall be used to
report the next strongest identified cells in the other bands
irrespective of the band used.
2 (10) The MS shall report the two strongest cells, with known
and
allowed NCC part of BSIC, in each of the frequency bands in the
BA list, excluding the frequency band of the serving cell.
The remaining positions in the measurement report shall be used
for reporting of cells in the band of the serving cell.
If there are still remaining positions, these shall be used to
report the next strongest identified cells in the other bands
irrespective of the band used.
3 (11) The MS shall report the three strongest cells, with
known and
allowed NCC part of BSIC, in each of the frequency bands in the
BA list, excluding the frequency band of the serving cell.
The remaining positions in the measurement report shall be used
for reporting of cells in the band of the serving cell.
If there are still remaining positions, these shall be used to
report the next strongest identified cells in the other bands
irrespective of the band used.

This
display is used to toggle BTS_TEST status on EEPROM. If BTS_TEST
status
is set on EEPROM each time the mobile sends a search list it uses
only
the carrier number stored on SIM SCM-location 33. Also the neighbour
information
from system information messages is ignored. If the BTS_TEST
status
is not set, then the value of SIM SCM-location 33 is ignored and the
mobile
behaves normally (i.e. does the neighbour measurements according the
GSM
specifications).
To
activate BTS tests perform following steps:
- Save desired channel number in SIM SCM-location 33.
- Select display 17 in execute mode
- Switch power off and on
If
activation succeeded, there is text "BTS TEST ON" in display 17.
To
deactivate BTS tests either select display 17 in execute mode or
save
number 0 in SIM SCM-location 33 and switch power off and on.
NOTE!
The display does not show the value of BTS_TEST status in EEPROM.
Although
the value is set, bts test can be off. If there is not legal
carrier
number in SIM location 33 (GSM: 1-124, DCS1800: 512-885) the
display
shows that bts test is off. Also if the mobile was already
registered
to some carrier before switching BTS_TEST status, the display
can
show different value from the one in EEPROM.

This
test is meant to be used when some cells are tested prior taking them
into
commercial use. By setting the barring on in the base station normal
GSM
phones will not try to register these barred cells. By selecting cell
barring
reversed, the MS will only use the cells to be tested. However, if
at
the same time it is wanted that MS will be capable to use normal network
cell
barring ignored can be set. Display 19 will show the cell barring
mode.
NOTE!
If a cell has been selected before barring state is changed the
selected
cell may have different barring state than what the display shows.
After
reselection the cell barring state is working for sure.
