- TCOMP - an other threshold to add an active PN when a candidate PN becomes stronger than an active PN
- TTROP - timer to drop a PN when power of this PN goes below TDROP
- WW1 - value of the seach window for the active PN

it is connected with data transmission.
In line with Rx and Tx you see, which Time Slots are used for it
(for receiving and transmiting).
When phone doesn't use HSCSD (High Speed Circuit Switched Data),
only one time slot is used both for transmiting and receiving
(it's visible also in test 1 then).
When use HSCSD, only this test gives full information about it...
You can check here, what can be maximal theoretical speed for downloading
and uploading data (number_of_used_slots * 9600 or number_of_used_slots * 14000)...
mCh seems to be "main" time slot among them used for transmission
(one that seems to be always used for both ways - probably can be viewed as the slot
that would be used if no HSCSD were used, and all other slots are "extra" slots to
increase number of sent/received data). It seems to be displayed in
test 1 too...
mPw seems to be the power level for the "main" time slot
(it seems to be displayed in test 1 too - units
are the same)....
The power levels for all 8 individual slots can be found in
test 9.
First line shows channel displayed in test 1 too.
It's available in new firmware only (5.02).

and is connected with HSCSD (High Speed Circuit Switched Data)
and shows power levels for each time slot
used in data transmission
(more info about data transmission in Nokia 6210 is visible also in
Test 8). Units here seems to be the same to units
in test 1 (power level used for "main"
time slot in transmission is displayed also there).
Test 10

PRP:d ee ff
ggggg hhh |
|
TMSI(hex)
T3212ctr/tim
PaRP DSF AGC
AFC Ch |
|
-
aaaaaaaa - TMSI:
a number assigned to each phone logged to the network (it can be done, for
example, after power on, a call, sending/receiving SMS, requesting some services,
PLU). Value from the SIM card
(each new number is written there) in hexadecimal format. If assigning this
number fails (for example because transmitter was turned off in
test 45 or SIM card is not active),
'xxxxxxxx' is shown here and the phone displays 'No network coverage' message (when you try
to make a call).
-
bbb - value of the so called T3212 counter: the phone periodically informs
the network about its location
(makes a PLU). 'bbb' counter means time from
last update and can be a value from 1 to 'ccc' (where 1 means 6 minutes, 2 -
2 * 6 min = 12 min, etc.). This counter is also cleared after each connection,
sending/receiving SMS or requesting a network services - for example call
diverting (but the counters from test 64
don't change). The value doesn't change (it's always equal 0) with not active
SIM card.
-
ccc - max T3212 counter value: period of time, after which the phone sends
information about its location - makes a PLU
(range from 1 to 240, where 1 means 6 min between updates and 240 means
24 hours (240*6min)). This value is received from the network (if it is 0,
the network doesn't require information about phone location). For Polish
networks Era GSM and
Plus GSM it's equal 30 (3h), for
Idea 2h. Displayed normally
even, when SIM card is not active.
-
d - Paging Repeat Period, sometimes called DRX (Dincontinuous Receive):
period of time, after which the phone turns its receiver on to check whether
someone is calling us (range from 2 to 9 - the higher, the longer time between
these checks so the phone uses less power:
PRP=2 means about 0.95 s, a PRP=9 equal 4.25 s.).
Interesting thing is that max standby times are usually calculated by the manufacturers
for this parameter equal 9.
-
ee - DSF (Downlink Signalling Failure). If it is negative,
0 is shown. Max value of this parameter is 45. When the phone uses
TCH channel, xx is displayed.
-
ff - AGC (Automatic Gain Control) - automatic gain control
of the phone receiver. The stronger the signal from BTS,
the lower this value. It is displayed correctly only when the phone uses
TCH/SDCCH channel
(for example: during a call) and can be a value from 0 to 96 (dB ?).
-
ggggg - in some English descriptions it's "VCTCXO AFC DAC control" - a value
between -1024 and 1023. In help it's described as AFC
(Automatic Frequency Control) - automatic adjusting phone's
receiver to the frequency of the signal transmitted by BTS.
The more this value differs from 0, the more frequency corrections have to be
made by the receiver (it depends on the channel used in communication with
BTS - see test 1)
to "match" the BTS.
-
hhh - CH (channel): number of channel used in communication with cell (decimal)
In Nokia 2110i/2140:

If the phone after power on wasn't logged to any network,
some default values are displayed here (except for TMSI).
Some of these values can be also found in Nokia service programs
(for example in WinTesla - in menu "Testing" / "RF Information").
|
In test 64 you can check,
how many times your phone has sent an information about its location.
If you have sent an SMS, you can check (exact to 6 min), when you did it
(if it wasn't earlier than value 'ccc' for your network) - check 'bbb' parameter value.

Identification of the currently used (last monitored) network
CC:aaa NCbbb
LAC:ccccc
CH : deee
CID:fffff |
|
MCC MNC
LocAreaCode
ServChannel
CellId |
|
-
aaa - MCC (Mobile Country Code): code of the network home
country (260 for Poland) - decimal.
-
bbb - MNC (Mobile Network Code): network code
(different for networks with the same MCC - for example, in Poland:
01 for Plus GSM, 02 for Era GSM and
03 for Idea).
Generally values here are decimal. Sometimes are exceptions (when and why ?)
and you can find hexadecimal value here: if you will convert it into
decimal and result treat as hexadecimal value (convert it into decimal value
again), you will have decimal value of this parameter (for example,
3F hex=63 dec; 63 hex=99 dec).
When you use phone working in PCS 1900
system (for example, Nokia 6190), this number can be 3-digit long. It's decimal (always ?).
If it consist of two digits, you will see "?" instead of last (for example,
you will see "37?" for "37")
-
ccccc - LAC (Location Area Code): code of the current
cell area (decimal or hexadecimal). The size of this area (with the same LAC)
depends on the network. After changing LAC, the phone makes
Location Update.
-
d - H, if frequency hopping is enabled (otherwise empty). This information
can be also found in test 1 and
test 12.
-
eee - CH (channel): number of channel used in communication with cell (decimal)
-
fffff - CID (Cell Identifier): number of the current cell
(each cell in given area has its own unique ID number) - shown decimal or hexadecimal.
LAC and CID format (if they're displayed decimal or hexadecimal) depends
on your phone's model and its software version (for instance: Nokia 3210
and Nokia 5110 with newer software display decimal values, while Nokia 5110
with 4.59 (and older) firmware and some previous models (like Nokia 3110)
use hexadecimal format).
GSM phones recognize the network using MCC and MNC codes
(list of these codes can be found at
http://kbs.cs.tu-berlin.de/~jutta/gsm/gsm-list.html).
Network names shown on phone's display (like 'ERA GSM',
'Plus GSM' or 'Idea')
are stored in phone's memory (they're set by the producer - cellular network doesn't
send any name, just these two numbers). In order to correctly recognize a
new network, you must upgrade the firmware of the phone (or it won't display
network name). Some older phones, like Nokia 2110i (or newer models
without firmware upgrade) display names like PL-03 (they recognize that
MCC=260 is Poland (which has international code PL), but they don't know
the network name - only its MNC). One (?) text name can also be changed
using appropriate programs:
In Polish version of this manual the description of BTSes contains
URLs of pages with BTSes lists - with their locations, LAC and CID
(for Polish networks).
If the phone after power on wasn't logged to any network, some default values are displayed here.

Test 17
USERS OF NOKIA 6210 HAVE TO READ FIRST NOTES WRITTEN ON THE END OF DESCRIPTION
FOR THIS TEST. IN OTHER CASE THEY CAN DAMAGE THEIR PHONES.
This menu lets the phone test one concrete channel used in communication
with cell (the phone doesn't seek channel with the strongest signal, but uses
the channel chosen by you: you can use channels 1-124 for GSM 900
and 512-885 for GSM 1800). Each GSM network has its own assigned channels
from these ranges (which means that each two networks in one country can't
use the same channels - for example, in Poland Plus GSM
cannot use Era GSM channels and vice versa).
| GSM 900 (1-124) | GSM 1800 (512-885) |
TIM (222-01) | 8-64 (16 most important cities) or 8-50 (outside them) | 736-760 |
Omnitel (222-10) | 66-118 (16 most important cities) or 77-118 (outside them) | 861-885 |
Wind (222-88) | 52-75 (outside 16 most important cities) | 761-810 |
Blu (222-??) | - | 811-860 |
Plus GSM (260-01) | 1-14 and 37-67 (37 and 67 for testing) | 749 - 760, 850 - 884 ? |
Era GSM (260-02) | 15-36 and 68-90 (15 and 36 for testing) | 736 - 748, 811 - 847 ? |
Idea (260-03) | 91-114, 115-124 from January 2004 | 733, 763 - 810 |
You can enter numbers of channels belonging to any network (if you enter
a channel of forbidden network, you will see all network parameters,
but obviously you won't be able to establish connection (except for
emergency calls)). After enabling this test your phone won't be able to make
handovers.
To enable this test, proceed as follows (sometimes this procedure doesn't
work - but turning the phone off and then on often helps; I don't know why):
-
save (change) desired channel number on position number 33 of the SIM card's
phone book in decimal format (not in phone's memory!) -
if you save '0' there, this test will be inactive!
However, this step is not necessary, if this number was stored there earlier -
you can check this with 33# code). Remember, that phone checks used format. Here are
some examples of correct entries: "1", "700".
- go to test 17
- once again enter test 17 directly
- switch your phone off and then back on
To disable this test:
- enter test 17 directly
- switch the phone off and back on (sometimes it isn't needed -
phone should disable test, when loose signal on this channel;
but it's better to do that to avoid potential problems)
Some interesting results can be achieved, when (guess why ?):
- you enable this test
- then you switch test 19 to REVERSE
- turn off the test, but not the phone (by entering test 17 one time in a direct mode)
In this case the phone "jumps" from one channel to another and monitors
channels of different networks - you can see LAC and CID codes of the cells.
Furthermore, the phone cannot log to its home network (though it displays
parameters of its channels). Several times I got "Insert SIM card" or
"SIM card rejected" messages - it may be some bug in firmware. After turning
the phone off and then on everything works fine.
|
The above tip can be used for fast battery discharging (however your phone
won't be accesible in the network).
If you want to check some informations about different than your network, you
can use different tip too:
- select the test, where will be displayed interesting for you information
about this network
- go to the manual network selection (for example, Menu 4-2-4-2 in Nokia
5110)
- select interesting for you network
- wait few seconds (some time is required to start logging into this network)
and press "Quit" (NOT (c) key) or wait, until phone will display any message
(for example, that logging wasn't successfull)
- press fast (c) key to leave phone's menu
Information about interesting for you network will be displayed during few seconds...
|
I heard about some cases, when this test turned itself spontaneously on
after loosing the signal by the phone. I didn't experience this, but if this
has ever happened to you, just save 0 on 33rd position of the SIM card's phone
book.
|
Since Nokia 51xx/61xx phones don't allow choosing the position for the phonebook entry,
I want to suggest:
- check whether you already have some number stored on this position
(using 33# code)
-
if the phone displays 'Invalid location', you have to add new entries to the
phonebook until you hit this position and the phone doesn't display this
message (repeating 1st step after each new entry)
-
after displaying the number, you have to find out who's number is this.
You can do it in two ways:
-
just recall (or check the whole phonebook)
-
turn off the transmitter in
test 45 and call this number
(the name assigned to this number will be show on screen - you will also find
it on the 'Last dialed' list)
-
edit the phone book (this position) - you can change the name or the (channel) number
-
if the phone asks you, whether to replace the old number or to save it on new location, choose the former option
To store number on chosen location you can also use other Nokia phone
(for example 2110), other cellular phones or appropriate software.
For example: in Nokia Cellular Data Suite you can export list of phone numbers
to file, open it in editor, change and upload to phone. It's simple, isn't it ?

-
aaa - can be set to "ON" or "OFF"
|
This test can be very usefull when:
-
you want to use some particular cell (for example to test whether it is
possible to use a cell located 20 km away)
-
you'd like to avoid roaming (which is much more expensive) - for example
when you are close to the border (and the phone constantly logs to the network
of the neighbor country, because it has a stronger signal) - you just switch
your phone to the channel used by your network...
-
other available network has very strong signal (for example -85 dBm) and the
signal of your home network is very weak (-100 dBm) - your phone can have
serious problems with logging to your network until you use this test
-
you want to monitor the state of some very weak channel - I received some mails, that
the lowest measured with this method signal strength was -118 dBm

Many users of Nokia 3210 say, that in this model there are problems with enabling
and disabling this test - part of firmware connected with it has probably some bug(s)...
I read even in one newsgroup such post (here is in translation):
Few people after enabling test 17 made reclamations in service, that phone
doesn't work. The most interesting is (I'm sure, that in one case) reclamation
was taken into consideration !!!! - phone was exchanged !!!
In new models (Nokia 3310, 6210, 6250, 8210) it's a little different:
...but you can use it very similiar (to enable):
- enter it directly. You should see:

where instead of "bbbb" parameter you should see value read from position 33

was not ready, etc. - of course, you will not enable this test then).
- restart phone - "aaa" parameter should change to "ON"
To disable this test you should:
- enter directly into it
- restart phone - "aaa" parameter should change to "OFF"
BE CAREFULL IN MODEL 6210 WITH THIS TEST
In firmware 4.27 (older probably too, I don't know, if it's corrected in newer)
phone can display CONTACT SERVICE after using it or
there could be different problems with it. Here are three known examples:
- after enabling test everything was correct. After writting number 0
and resetting phone (it was one method for disabling this test in older models)
CONTACT SERVICE was displayed. User put SIM card into another phone, changed
33 position in phonebook to CORRECT channel number
(1-124, 512-885), put SIM back to 6210 and normally used it (second
6210 with the same symptoms wasn't repaired after making it).
- in this concrete example Nokia 6210 displayed info about finding channel 79.
User written its' number in phonebook on 33'th position. After third reset
of phone CONTACT SERVICE was displayed. SIM card was put into Nokia 5110 and
channel number was changed to 76 (this channel was visible in this phone).
When SIM card was put back into Nokia 6210 phone, it was possible to enable
it. In this test phone displayed 'BTS TEST ON CH:79' (channel 79 was also visible
in test 3).
- after enabling this test phone was restarted. After entering PIN it hanged,
"Code accepted" was displayed and it squeaked. And the same problem
was visible after each reset. User disabled netmonitor via cable.
After it phone phone very often wasn't able to find network and user had
to disable it. Solution was disconnecting battery for about 1 hour.
Problems with finding
network were visible during about next 2 weeks.

This menu allows you to turn on constant backlight of the screen and keyboard
(LIGHTS ON). This can be used for very fast battery discharging. We can also
use it as a flashlight - for example to check a schedule, your location on a
map, to be visible on the road :-), etc. But there is one condition:
any of the NetMonitor tests must be visible on the screen.
If you turn this test on and then back off, the light will go out
(it won't react on key presses) for several minutes (good for games -
saves battery)...
The light can be also constantly enabled, if you connect a car kit
(or simulate it - check test 75)
and "Light" setting (Menu 2-5 in Nokia 5110) will be set to "All".
This will work without NetMonitor (and any of its test) enabled!

In Nokia 2110i/2140:
Test 19
|
Each operator before giving a new or repaired base station
(BTS) for normal use, tests its cells.
GSM phones read this information and avoid using these cells. However, using
this menu, you can set your phone to use such cells, too
(DISCARD option) - sometimes it allows you to "improve" the coverage and range of your
network .
If you want your phone to use only such barred cells, just set this menu to
REVERSE (but you won't be able to make or receive calls if there are no tested
cells in your neighborhood - good phone lock ?).
ACCEPTED means that your phone uses only normal cells, which are allowed for use
(it works like any other phone).
|
Information about cell status is broadcasted on BCCH
channel as a CELL_BARRED parameter value. The settings of this menu can be
changed by entering it directly (but if you have previously enabled test in
test 17, current cell may have other status
than the chosen here (for example: you chosen barred cells only, but the phone
uses a normal one)).
New settings are applied during next signal quality measurements (you can
advance this by making a call, forcing the phone to search for a network or
by holding the antenna with fingers for certain amount of time).
Sometimes your phone may not be able to find cells with particular status
- it will show parameters of the cells with such status belonging to other
network (once I've set this menu to REVERSE and the phone started displaying
data of barred cells in forbidden for my SIM card network, because there were
no tested my home network cells in my neighborhood). Information about cell
status can be found in test 1 to
test 5.
The phone works as any other GSM phone (default) - only normal cells

The phone uses only tested cells |
The phone uses all existing cells (both normal and barred ones) |

i - information, whether travel charger is connected (1) or not (0)
Fast charging (FastC in NetMonitor) means charging with bigger current
and with clever charger it doesn't damage your battery.
When battery charging is ended, maintenance charging starts
(it's normal, that phone uses some energy and battery's discharging process
starts; still connected charger can complete energy losses).
In Polish version of this manual you can also find links to some pages
in Polish language explaining some topics connected with charging and batteries.
For curious people: some of the data, which are displayed here, can also be
found in Nokia service programs (like WinTesla - menu "Testing" / "ADC Readings...").
|
This test allows us to check the charger. You can also verify some of the battery parameters like:
-
capacity
-
efficiency (of the battery cells)
-
voltage (if you are - say - on a trip, here you can check whether battery voltage is suitable for your flashlight)

-
fff - the sum of the parameters from test 22
(range 0.00 - 9.99, for example 1.53 is displayed as 153) - my own observations
show, that DerivCount (Eaaa) parameter is not counted here. If this counter
reaches 1.00 or 0.99, 'Battery full' message is displayed and bar indicator
on the right side of the display stops.

Here you can find several charging parameters and indicators.
All these fields (except for DerivCount) range is from 0.00 to 1.00
(dot is not shown - for example 0.23 is displayed as 023). After disconnecting
the charger these fields can contain various values. Letters E, C, D, R, I,
A, T and V are displayed when the number is shorter than four digits.
I received info, that in some (all ?) Nokia 6150 phones with firmware 4.13
(LiION battery) there are ALWAYS displayed these values (is it bug in this
version of firmware ?):

-
aaaa - voltage from the battery when transmitter is active (a.aaa mV)
-
bbbb - voltage from the battery when transmitter is inactive (b.bbb mV)
-
cccc - charging current (c.ccc mA). If the charger is not connected, 0 is shown.
In Nokia 3210 ALWAYS equal 0 (I think, that firmware in this model has some bug).
-
dddd - expected voltage from the battery in standby mode (d.ddd mV). You can
check whether your SIM card 's clock can be stopped in
test 51.
-
eee - estimate battery age (0 - new, 100 - old) for LiION batteries (the
value of this counter is probably based on measurements of work/discharging
time of the battery and its capacity (shown in test 20);
this is only a reference!) or 33 for NiMH batteries.
-
fff - battery charge level in percent (in older phones, like Nokia 5110,
25 - 1 bar, 50 - 2 bars, 75 - 3, 100 - 4 bars on
the right side of the screen; in never, like Nokia 6210 - 100 - 6 bars,
80 - 4 bars, 60 - 3 bars, 40 - 2 bars, 20 - 1 bar).
This indicator (and parameter) is very
inaccurate during charging process (it reaches 100 almost immediately) -
better use ii and jjj parameters then.
-
gggg - temporary power consumption indicated by PSM (according to some
English descriptions in decimal parts of mA; I think that this field shows
values in mA - see on calculation of approximate battery work time below)
-
hhh - LiION battery temperature (also shown in test 20
- sometimes both these indicators are different) or 0 (for NiMH battery)
-
iiii - how many mAh were "loaded" to the battery until now. If it is approximately
equal to jjj, the latter parameter raises (or charging is complete). This parameter
is cleared after each use of TCH channel
(for example: after a call) while charging (with NiMH battery) - you can use
this tip to extend charging time almost ad infinitum. I noticed it with Nokia 6110
and LiION battery (when I turned off and on phone during charging process) too.
This value is updated every 14 seconds (Nokia 5110 with standard charger).
-
jjjj - battery capacity value (in mAh) by which next charging stage is complete
(see description of the previous parameter). I noticed, that it's cleared
during LiION battery charging (when I turned off and on phone during charging
process) in Nokia 6110.
For curious: some of the data, which are displayed here, can also be found
in Nokia service programs (like WinTesla - menu "Testing" / "ADC Readings...").
|
Here you can check your battery type (LiION or NiMH).
|
Approximate power consumption (this can be changed and modified by many other factors) while using individual channels
(Nokia 5xxx and 6xxx):
Turning on backlight takes 90 mA more, and while charging another 17 mA should be added.
In Nokia 3210 these data are different for different person (does it depend on firmware version,
frequency ?)
standby | reading BTS identification data | turning on backlight |
52 mA | 90 mA | +155 mA |
8 or 9 mA | ? | +159 or +160 mA |
53, sometimes (rarely, during short time) 8 mA | 93 mA | +158 or +159 mA |
8 mA | ? | +154 mA |
|
If you know the power consumption, you can calculate approximate battery work time:
-
900 mAh / 225 mA = 4 hours of talk time (on average)
Please note, that when using SDCC channel
the phone initially uses full power and the gradually reduces it.
-
900 mAh / 5,45 mA = 165 hours of standby time (on average)
Remember, that the phone makes PLU even in standby mode.
