Existence of the individual test in your phone depends on:
-
-
-
-
phone model: generally, never and more complicated models (with more functions and options) have more tests (for example,
-Nokia 9110 has more tests than 5110, 7110 more than 9110). There is one (only ?) exception: less complicated Nokia 5110
-has bigger NetMonitor than 6110 (and thats why I think that this model is better, even though it doesnt have some functions).
-
-
software version - usually the newer version, the more options it has (software can be upgraded in service and its
-version can be checked in most models with *#0000# code, in Nokia 6130 with *#9999# and in
-3110 with *#3110#) for instance in Nokia 5110 in test 89 bbbbbb
-parameter is shown only from firmware 5.07. Firmware upgrade has also additional advantage: newer versions dont
-contain some bugs (also in NetMonitor).
-
-
who uploaded firmware to the phone: it is usually written in C (and then translated (compiled) to the code of phones
-microprocessor). According to my own private theory existence (and running) of an individual tests depends on some
-constants set (or not) in the source code (programmers :-) surely understand, what Im trying to write). The best example
-for this can be test 38: according to the some English documentation
-it doesn't exist in phones to be sold, because DEV_FT_MEMORY_DUMP_IN_USE constant in file ftd_conf.h
-(one of the firmware source code files) wasn't set before compiling. I think, that the same applies to the help screens
-their presence doesnt depend on firmware version but on where the phone was purchased (where it comes from
-where was its firmware uploaded). How to solve this problem? Unfortunatelly, you can only download firmware again (compiled
-from source with set constants).
-
-
Aha, Im also not quite sure, whether DSP tests
-(test 70, 10-73,
-10-74,
-10-76 (except for ab parameter), 10-77,
-10-78
-and 10-79) dont have to be enabled this way (or whether their existence
-(or not) depends on the network).
-
-
-
-
Help screens for tests are written with bold font,
-concrete (example) values in tests with italic (I put them there, where I didn't have more details about test).

-
-
-bbb - CH (channel): number of the channel used in communication with cell (decimal). If
-frequency hopping is enabled, this number changes when the display gets refreshed.
-This parameter determines frequencies used in communication with BTS:
-
-
-
-
-
carrier (middle) frequency
-of the transmission channel (MHz)
-
-and informs, whether phone use cell working in GSM 900 or 1800 MHz
-(I write more about channel numbers in test 17).
-
-
-
-
-
-
-
ccc - RX:
-minus is not show if <=-100. This parameter affects following functions:
-
-
-
-
-if all channels signal is weaker than -110 dBm, the phone doesnt monitor channels.
-
-
-if the phone loses signal of your home network, it tries to monitor next available networks and if you don't have access to them,
-youll see a network presence symbol and no signal strength bars (but you can make emergency calls)
-
-
-
- if some other network has a very strong signal (say -85 dBm) and your home network is very weak on that area (for example,
--100 dBm), your phone can have big problems with logging into it (you will have to use
-test 17 to manually force the phone to use proper channel).

ddd - TX: level of the transmitted signal (only during connection). If the phones transmitter is active,
-there is an * (asterisk) before the value. The lower value, the higher power level (also the one received by your head!) and
-energy consumption.
-
-
There are following classes describing max phone transmission power:
-
-
-
-
GSM 900
GSM 1800
-
-
-
-
20 W (not in use)
- 8 W (car/mobile phone)
- 5 W (car/mobile phone)
- 2 W (hand phone)
- 0,8 (hand phone)
-
-
-
-
1 W (hand phone)
- 0,25 W (hand phone)
-
-
-
-
-
Min. phone transmission power in GSM 900 is 0,02 W and in GSM 1800 is 0,0025 W (4 dBm).
-
-
Max BTS power level can be found in their description.
-
-
-
-
-
e - This TS indicator shows number of the used time slot
-(0..7 for FR (EFR) or 0..15 for HR).
-For phones with HSCSD (like Nokia 6210) use also test 8 for it.
-
-
-
-
ff - TA (Timing Advance): BTS informs the phone,
-when it should start transmission (so that it reaches BTS in time). This information is shown
-by this indicator. It lets us calculate approximate distance between phone and BTS, which is
-a value between TA*550 m and (TA+1)*550 m (remember, that sometimes signal is refracted and
-distance evaluated with this parameter can be wrong).
-This parameter is updated during communication with network (sending/receiving
-SMSes, calling, requesting services), for example when using SDCC and TFR
-channels. It ranges from 0 to 63 (up to 35 km) with FR and
-EFR channels. HR channels offer theoretically (for example
-with a car antenna (higher transmitting power) and a flat terrain) twice this range (up to 70 km) and TA contains value up to 128
-(English descriptions which I use dont say a word about it - so, it's possible,
-that for values bigger than 64 phone (?) decreases 64 from it and displays such value in this menu).
-
-
Tip: you can use ALS (Alternative Line Service) function or
-try to call for "*" number, when you want to refresh it...
-
-
-
-
-
g - RXQUAL_SUB (rate of transmission errors with DTX active
-(DTX state can be checked in test 12)):
-it determines, how many errors during connection have to be corrected by the phone for the call to be possible. Range 0 - 7
-(0 means no errors; more than 5 connection may be interrupted). The higher it is, the worse quality you have...

-
ppp - C2 parameter. If network supports only GSM Phase 1,
-C1 value is displayed here.
-
-
-
-
oooo - type of channel currently used by the phone (visit
-www.pins.co.uk/upages/stratfordc/
-to find C programs containing algorithms used to encode different channels).
-With HR channels phone even show, if first or second
-part of TS is used (subchannel 0 or 1 is written):
-
-
-
-
-
-
AGCH
-
(Access Grant Channel) - a channel used by
-BTS to inform the phone about what channel it should use (it is a
-BTS answer to RACH) it assigns the phone to
-SDCCH
-
-
-
-
BCCH
-
(Broadcast Control Channel)
-- a channel in direction BTS-phone, containing precise information about network
-(needed for identification and access) for example
-
-
-
how often the phone should inform network about its location (T3212 counter value more detailed description in
-test 10)
CELL_RESELECT_HYSTERESIS parameter (see C2 parameter description)
-
CELL_BARRED parameter (which informs, whether this cell is in test phase or is available for public use but the phone
-can ignore this and use test cells too - see test 19)
(Common Control Channel ?) - used, when the phone is in standby mode (it doesnt transmit not receive data)
-
-
-
-
CBCH
-
(Cell Broadcast Channel) -
-a channel in BTS-phone direction used for cell broadcast (for example in Nokia 5110 it can
-be enabled in Menu 2-5 and Menu 4-2-2, in Nokia 6110 in Menu 1-5 and Menu 4-4-2)
-
(No Serve Power Save)
-- the phone is not in range of any network, energy saving has been activated (information, whether your SIM card can stop its
-clock in energy saving mode, can be found in test 51)
-
-
-
-
-
-
Interesting thing: In firmware in Nokia 3210 and 3310 there are strings
-which shows info about data transmission state
-("officialy" these phones don't have this function)...

5-7 (2 - 0,794 Watt)
-
-
-
For curious people: some of these data can also be found in Nokia service programs (for example in WinTesla in
-"Testing" / "RF Information" menu).
-
-
-
-
-
-
Using CCCH or CBCH channel by the phone
-(if the cell doesnt support cell broadcast you can check this in test 7) depends
-on its firmware version and whether cell broadcasting has been enabled (or not) by the user. For example: Nokia 5110 v 5.04
-uses CBCH channel, if you enable this feature in Menu 2-5 or Menu 4-2-2
-(and CCCH channel, if you disable it). I think, that cell broadcast should be disabled when it is not
-supported by the network probably you can save some battery power. It has been corrected in version 5.07 (when CB is
-not supported by the network, the phone uses CCCH regardless of "Info service" and
-"Cell info display" settings).
-
-
Additionally, ccc (RX) parameter can be used to set the direction of your antenna
-(especially directional one) much more precisely than when using the indicator on the left side of phones display !
-I also have a piece of advice for you: never touch the antenna (in any case, you can check how it affects level of received
-signal just by holding it with your fingers) !
-
-
TA parameter can be also used (apart from calculating the distance to BTS)
-to measure speed (for example of the care youre driving). Im serious! But this can be done only when:
-
-
A little bit of mathematics:
-
- From Pitagoras theorem:
-
-
a2 = c2 + e2
- b2 = c2 + f2
-
-
So:
- e =
- f =
-
-
Now d = e - f =-
-
-
If you know:
-
-
-
-
-the way traveled by the car (on the drawing: length of "d" segment; it can be calculated form the lengths of "a" and "b"
-segments (multiples of 513 m (for simplification) read from TA) and c (described later))
-
-
-
-time, in which TA has changed (measured by a stopwatch)
-
-
-
-
you can measure your speed.
- Inaccuracy of this measure depends on:
-
-
MINMAX: Minimum and Maximum RSSI over last time period ?
-

This test allows you to recognize, how many neighbor cells can "observe" phone

-in Nokia 5110/3310/6210 only in first row (6 cells).
-
-
In Nokia 3310/6210 parameters "ef" are never displayed (you can see "xx" only)...
-These models during standby mode can see only 6 cells, during call 8...

-
-

-
-
-
-
-ROM SW
-EPROM SW
-Prod type
-
-
-
-
-
-
-
-
ROM SW = ROM software version, e.g. V 65.08
-
EPROM SW = EPROM (flash) version, e.g. V 1.45
-
Prod type = product type, e.g. NHC-4NE
-
-
-
And here is for Nokia 6160:

-
-
-
-
-
-S bandorde
-NC NP IRC
-RSCO RSLO
-
-
-
-
-
-
-
-
-
S = system indicator:
-
-
H = hometype system
-
P = partner roam
-
F = preffered roam
-
N = normal roam
-
X = no service
-
a, b, A, B, C, D, E, F = current band while scanning for a control channel
-(see next parameter for details)
-
-
-
-
bandorde = network search order:
-
-
a = a-side 800mhz cellular
-
b = b-side 800mhz cellular
-
A = A-block (30 mhz) 1900mhz PCS
-
B = B-block (30 mhz) 1900mhz PCS
-
C = C-block (30 mhz) 1900mhz PCS
-
D = D-block (10 mhz) narrowband 1900mhz PCS
-
E = E-block (10 mhz) narrowband 1900mhz PCS
-
F = F-block (10 mhz) narrowband 1900mhz PCS
-
-
-
-
NC = Number of Cellular = number of probability blocks to scan in cellular bands
-
NP = Number of PCS - number of sub blocks to scan in PCS bands
-
IRC = IR Control:
-
-
1 = only systems with home SID or SOC are accepted
-
0 = any system not listed as forbidden is accepted
-
-
-
RSCO = Rescan Count - rescan time in hyperframes
-
RSLO = Rescan Loop - defines when all the bands in bandorder are to be scanned
-last registered network - you used it last time. When you're in home country, it can be your home network
-(you pay them for your calls - if it is, after choosing it manually (in Nokia 5110 - Menu 4-2-4) phone displays
-"Home network selected"). 00000, when phone wasn't registered in any network
-after enabling.
-
-
-preferred network - network, to which your SIM card was logged (when it was in its range) for example in roaming.
-
-
-
-forbidden network your SIM card was in range of that network, but wasnt allowed to log in...
-
-
-
-
-
-
aaa - MCC (Mobile Country Code)
-- code of the network home country (260 for Poland). Decimal value.
-
-
-
-
bb - MNC (Mobile Network Code)
-- network code (different for networks with the same MCC).
-
-
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). More about it in the question 23.
-
-
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 "F" instead of last (for example,
-you will see "30237F" for 302-37 network)
-
-
-
-
-
What are these lists stored on SIM card for? Because:
-
-
-
-
-the phone doesnt have to waste its power while trying to log to the network, which is forbidden for SIM card
-(it is checked only once and then stored, so the phone doesnt have to repeat this procedure anymore)
-
-
-
-when you have automatic network selection enabled, your phone in first turn searches for networks it was
-previously using ("preferred").
-
-
-
-
-The list of "preferred" and "forbidden" networks is written by the phone
-(Nokia saves last chosen networks). Preffered networks can be also edited for example in Motorola and Alcatel phones (not in Nokia).
-Sometimes it is done by
-the operator (he writes preferred and forbidden networks to the SIM card before selling it (it's known, that you cannot
-log to competitive network it can be stored in card programming phase). Both these lists can be changed using a
-Czech program called SIMedit (www.compelson.cz/simedit.htm)...
-
-
This lists the total count of SOCs and SIDs in each category.
-The database has a total memory limit of 82 entries,
-which may be distributed amongst these categories:
-
-
-PSC = number of Partner SOCs
-PSD = number of Partner SIDs
-FSC = number of Preffered SOCs
-FSD = number of Preffered SIDs
-XSC = number of Forbidden SOCs
-XSD = number of Forbidden SIDs
-
-
Partner SOC/SID = treated like the home system by the phone
- Preffered SOC/SID = preferred over neutral (undefined) systems when available
- Forbidden SOC/SID = rejected by the phone as service providers
-
-
f - 1, if the cell supports cell broadcasting (CBCH channel)
-
g - 1, if cell re-establishment is possible
-
-
-
Last two lines are present only in dual phones (GSM 900/1800 for example Nokia 6150 and 3210):
-
-
-
-
-h - 1 in standby mode, if ECSC (Early Classmark) sending is supported. During a call "x" is displayed.
-
-
-
-i - 1 in standby mode, if 2-Ter messages are supported. During call "x" is displayed
-
-
-
-j - information (if supported) which cells from both frequencies bands (900 and 1800 MHz) are shown
-(MULTIBAND_REPORTING parameter value). Description from
-Phase2+ ETSI GSM 05.08 version 5.4.0, section 8.4.3 "Additional cell reporting requirements for multi band MS" specification:
-
-
-
-
-0 - 6 strongest cells (with known and allowed NCC from
-BSIC), regardless their frequency band (900 or 1800 MHz)
-
-
-1 - strongest cell (with known and allowed
-NCC from BSIC) in each frequency band on
-BA list, except for frequency band of the current cell. Remaining positions should be used to show cells in frequency band
-of the current cell. If there are free positions left, further strongest and recognized cells from other bands are shown (their
-frequencies bands are not important).
-
-
-
-2 - like in 1, but two strongest cells are shown first (with known and allowed NCC from
-BSIC) in each band...
-
-
-
-3 - three strongest cells are shown first...
-
-
-
-
-
-
If your phone wasnt logged to any network, some default values are shown.

Existence of the individual test in your phone depends on:
+
+
+
+
phone model: generally, never and more complicated models (with more functions and options) have more tests (for example,
+Nokia 9110 has more tests than 5110, 7110 more than 9110). There is one (only ?) exception: less complicated Nokia 5110
+has bigger NetMonitor than 6110 (and thats why I think that this model is better, even though it doesnt have some functions).
+
+
software version - usually the newer version, the more options it has (software can be upgraded in service and its
+version can be checked in most models with *#0000# code, in Nokia 6130 with *#9999# and in
+3110 with *#3110#) for instance in Nokia 5110 in test 89 bbbbbb
+parameter is shown only from firmware 5.07. Firmware upgrade has also additional advantage: newer versions dont
+contain some bugs (also in NetMonitor).
+
+
who uploaded firmware to the phone: it is usually written in C (and then translated (compiled) to the code of phones
+microprocessor). According to my own private theory existence (and running) of an individual tests depends on some
+constants set (or not) in the source code (programmers :-) surely understand, what Im trying to write). The best example
+for this can be test 38: according to the some English documentation
+it doesn't exist in phones to be sold, because DEV_FT_MEMORY_DUMP_IN_USE constant in file ftd_conf.h
+(one of the firmware source code files) wasn't set before compiling. I think, that the same applies to the help screens
+their presence doesnt depend on firmware version but on where the phone was purchased (where it comes from
+where was its firmware uploaded). How to solve this problem? Unfortunatelly, you can only download firmware again (compiled
+from source with set constants).
+
+
Aha, Im also not quite sure, whether DSP tests
+(test 70, 10-73,
+10-74,
+10-76 (except for ab parameter), 10-77,
+10-78
+and 10-79) dont have to be enabled this way (or whether their existence
+(or not) depends on the network).

+-100 dBm), your phone can have big problems with logging into it (you will have to use
+test 17 to manually force the phone to use proper channel).

ddd - TX: level of the transmitted signal (only during connection). If the phones transmitter is active,
+there is an * (asterisk) before the value. The lower value, the higher power level (also the one received by your head!) and
+energy consumption.
+
+
There are following classes describing max phone transmission power:
+
+
+
+
GSM 900
GSM 1800
+
+
+
+
20 W (not in use)
+ 8 W (car/mobile phone)
+ 5 W (car/mobile phone)
+ 2 W (hand phone)
+ 0,8 (hand phone)
+
+
+
+
1 W (hand phone)
+ 0,25 W (hand phone)
+
+
+
+
+
Min. phone transmission power in GSM 900 is 0,02 W and in GSM 1800 is 0,0025 W (4 dBm).
+
+
Max BTS power level can be found in their description.
+
+
+
+
+
e - This TS indicator shows number of the used time slot
+(0..7 for FR (EFR) or 0..15 for HR).
+For phones with HSCSD (like Nokia 6210) use also test 8 for it.
+
+
+
+
ff - TA (Timing Advance): BTS informs the phone,
+when it should start transmission (so that it reaches BTS in time). This information is shown
+by this indicator. It lets us calculate approximate distance between phone and BTS, which is
+a value between TA*550 m and (TA+1)*550 m (remember, that sometimes signal is refracted and
+distance evaluated with this parameter can be wrong).
+This parameter is updated during communication with network (sending/receiving
+SMSes, calling, requesting services), for example when using SDCC and TFR
+channels. It ranges from 0 to 63 (up to 35 km) with FR and
+EFR channels. HR channels offer theoretically (for example
+with a car antenna (higher transmitting power) and a flat terrain) twice this range (up to 70 km) and TA contains value up to 128
+(English descriptions which I use dont say a word about it - so, it's possible,
+that for values bigger than 64 phone (?) decreases 64 from it and displays such value in this menu).
+
+
Tip: you can use ALS (Alternative Line Service) function or
+try to call for "*" number, when you want to refresh it...
+
+
+
+
+
g - RXQUAL_SUB (rate of transmission errors with DTX active
+(DTX state can be checked in test 12)):
+it determines, how many errors during connection have to be corrected by the phone for the call to be possible. Range 0 - 7
+(0 means no errors; more than 5 connection may be interrupted). The higher it is, the worse quality you have...

mmmm - RLT (Radio Link Timeout): if it is negative, 0 is shown. Max value of this parameter is 64.
+If the phone uses a channel different than TCH or SDCC, xx is
+displayed
+
ppp - C2 parameter. If network supports only GSM Phase 1,
+C1 value is displayed here.
+
+
+
+
oooo - type of channel currently used by the phone (visit
+www.pins.co.uk/upages/stratfordc/
+to find C programs containing algorithms used to encode different channels).
+With HR channels phone even show, if first or second
+part of TS is used (subchannel 0 or 1 is written):
+
+
+
+
+
+
AGCH
+
(Access Grant Channel) - a channel used by
+BTS to inform the phone about what channel it should use (it is a
+BTS answer to RACH) it assigns the phone to
+SDCCH
+
+
+
+
BCCH
+
(Broadcast Control Channel)
+- a channel in direction BTS-phone, containing precise information about network
+(needed for identification and access) for example
+
+
+
how often the phone should inform network about its location (T3212 counter value more detailed description in
+test 10)
CELL_RESELECT_HYSTERESIS parameter (see C2 parameter description)
+
CELL_BARRED parameter (which informs, whether this cell is in test phase or is available for public use but the phone
+can ignore this and use test cells too - see test 19)
(Common Control Channel ?) - used, when the phone is in standby mode (it doesnt transmit not receive data)
+
+
+
+
CBCH
+
(Cell Broadcast Channel) -
+a channel in BTS-phone direction used for cell broadcast (for example in Nokia 5110 it can
+be enabled in Menu 2-5 and Menu 4-2-2, in Nokia 6110 in Menu 1-5 and Menu 4-4-2)
+
(No Serve Power Save)
+- the phone is not in range of any network, energy saving has been activated (information, whether your SIM card can stop its
+clock in energy saving mode, can be found in test 51)
+
+
+
+
+
+
Interesting thing: In firmware in Nokia 3210 and 3310 there are strings
+which shows info about data transmission state
+("officialy" these phones don't have this function)...

Level of received signal (RX) is connected with phone transmission power

7-9 (0,794 - 0,032 Watt)
+
from -85 to -93 dBm
5-7 (2 - 0,794 Watt)
+
+
+
For curious people: some of these data can also be found in Nokia service programs (for example in WinTesla in
+"Testing" / "RF Information" menu).
+
+
+
+
+
+
Using CCCH or CBCH channel by the phone
+(if the cell doesnt support cell broadcast you can check this in test 7) depends
+on its firmware version and whether cell broadcasting has been enabled (or not) by the user. For example: Nokia 5110 v 5.04
+uses CBCH channel, if you enable this feature in Menu 2-5 or Menu 4-2-2
+(and CCCH channel, if you disable it). I think, that cell broadcast should be disabled when it is not
+supported by the network probably you can save some battery power. It has been corrected in version 5.07 (when CB is
+not supported by the network, the phone uses CCCH regardless of "Info service" and
+"Cell info display" settings).
+
+
Additionally, ccc (RX) parameter can be used to set the direction of your antenna
+(especially directional one) much more precisely than when using the indicator on the left side of phones display !
+I also have a piece of advice for you: never touch the antenna (in any case, you can check how it affects level of received
+signal just by holding it with your fingers) !
+
+
TA parameter can be also used (apart from calculating the distance to BTS)
+to measure speed (for example of the care youre driving). Im serious! But this can be done only when:
+
+
A little bit of mathematics:
+
+ From Pitagoras theorem:
+
+
a2 = c2 + e2
+ b2 = c2 + f2
+
+
So:
+ e =
+ f =
+
+
Now d = e - f =-
+
+
If you know:
+
+
+
+
+the way traveled by the car (on the drawing: length of "d" segment; it can be calculated form the lengths of "a" and "b"
+segments (multiples of 513 m (for simplification) read from TA) and c (described later))
+
+
+
+time, in which TA has changed (measured by a stopwatch)
+
+
+
+
you can measure your speed.
+ Inaccuracy of this measure depends on:
+
+
MINMAX: Minimum and Maximum RSSI over last time period ?

This test allows you to recognize, how many neighbor cells can "observe" phone
+in the same time. Examples: in Nokia 6150 you can see info in all rows (8 cells),
+in Nokia 5110/3310/6210 only in first row (6 cells).
+
+
In Nokia 3310/6210 parameters "ef" are never displayed (you can see "xx" only)...
+These models during standby mode can see only 6 cells, during call 8...

+
+
+
+
+
+
+
+ROM SW
+EPROM SW
+Prod type
+
+
+
+
+
+
+
+
ROM SW = ROM software version, e.g. V 65.08
+
EPROM SW = EPROM (flash) version, e.g. V 1.45
+
Prod type = product type, e.g. NHC-4NE
+
+
+
And here is for Nokia 6160:

+
+
+
+
+
+S bandorde
+NC NP IRC
+RSCO RSLO
+
+
+
+
+
+
+
+
+
S = system indicator:
+
+
H = hometype system
+
P = partner roam
+
F = preffered roam
+
N = normal roam
+
X = no service
+
a, b, A, B, C, D, E, F = current band while scanning for a control channel
+(see next parameter for details)
+
+
+
+
bandorde = network search order:
+
+
a = a-side 800mhz cellular
+
b = b-side 800mhz cellular
+
A = A-block (30 mhz) 1900mhz PCS
+
B = B-block (30 mhz) 1900mhz PCS
+
C = C-block (30 mhz) 1900mhz PCS
+
D = D-block (10 mhz) narrowband 1900mhz PCS
+
E = E-block (10 mhz) narrowband 1900mhz PCS
+
F = F-block (10 mhz) narrowband 1900mhz PCS
+
+
+
+
NC = Number of Cellular = number of probability blocks to scan in cellular bands
+
NP = Number of PCS - number of sub blocks to scan in PCS bands
+
IRC = IR Control:
+
+
1 = only systems with home SID or SOC are accepted
+
0 = any system not listed as forbidden is accepted
+
+
+
RSCO = Rescan Count - rescan time in hyperframes
+
RSLO = Rescan Loop - defines when all the bands in bandorder are to be scanned
+last registered network - you used it last time. When you're in home country, it can be your home network
+(you pay them for your calls - if it is, after choosing it manually (in Nokia 5110 - Menu 4-2-4) phone displays
+"Home network selected"). 00000, when phone wasn't registered in any network
+after enabling.
+
+
+preferred network - network, to which your SIM card was logged (when it was in its range) for example in roaming.
+
+
+
+forbidden network your SIM card was in range of that network, but wasnt allowed to log in...
+
+
+
+
+
+
aaa - MCC (Mobile Country Code)
+- code of the network home country (260 for Poland). Decimal value.
+
+
+
+
bb - MNC (Mobile Network Code)
+- network code (different for networks with the same MCC).
+
+
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). More about it in the question 23.
+
+
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 "F" instead of last (for example,
+you will see "30237F" for 302-37 network)
+
+
+
+
+
What are these lists stored on SIM card for? Because:
+
+
+
+
+the phone doesnt have to waste its power while trying to log to the network, which is forbidden for SIM card
+(it is checked only once and then stored, so the phone doesnt have to repeat this procedure anymore)
+
+
+
+when you have automatic network selection enabled, your phone in first turn searches for networks it was
+previously using ("preferred").
+
+
+
+
+The list of "preferred" and "forbidden" networks is written by the phone
+(Nokia saves last chosen networks). Preffered networks can be also edited for example in Motorola and Alcatel phones (not in Nokia).
+Sometimes it is done by
+the operator (he writes preferred and forbidden networks to the SIM card before selling it (it's known, that you cannot
+log to competitive network it can be stored in card programming phase). Both these lists can be changed using a
+Czech program called SIMedit (www.compelson.cz/simedit.htm)...
+
+
This lists the total count of SOCs and SIDs in each category.
+The database has a total memory limit of 82 entries,
+which may be distributed amongst these categories:
+
+
+PSC = number of Partner SOCs
+PSD = number of Partner SIDs
+FSC = number of Preffered SOCs
+FSD = number of Preffered SIDs
+XSC = number of Forbidden SOCs
+XSD = number of Forbidden SIDs
+
+
Partner SOC/SID = treated like the home system by the phone
+ Preffered SOC/SID = preferred over neutral (undefined) systems when available
+ Forbidden SOC/SID = rejected by the phone as service providers
+
+
f - 1, if the cell supports cell broadcasting (CBCH channel)
+
g - 1, if cell re-establishment is possible

+
+
+
+
+0 - 6 strongest cells (with known and allowed NCC from
+BSIC), regardless their frequency band (900 or 1800 MHz)
+
+
+1 - strongest cell (with known and allowed
+NCC from BSIC) in each frequency band on
+BA list, except for frequency band of the current cell. Remaining positions should be used to show cells in frequency band
+of the current cell. If there are free positions left, further strongest and recognized cells from other bands are shown (their
+frequencies bands are not important).
+
+
+
+2 - like in 1, but two strongest cells are shown first (with known and allowed NCC from
+BSIC) in each band...
+
+
+
+3 - three strongest cells are shown first...
+
+
