NOKIA FAST NAM PROGRAMMING SOFTWARE
USER GUIDE
1. Introduction
This document is the user guide to Fast Nam Programming software.
The Putsub program has been produced to perform batch programming
of Nokia NHX–7 handportable telephones with the required subscriber
(NAM) data and SCM data via the Mbus serial interface.
The program is capable of programming TACS telephones to user defined configurations, drawing information from pre–defined data files,
which can also be generated and maintained using the program.
1.1 Material codes
Fast Nam Programming software v.1.30. Diskette code 0774081
Programming Cable DAU–9P code 0730109
2. Software Features
The program has a simple ‘Windows’ type user interface with operations
selectable by softkeys. When in use, the program auto detects the next
phone to be programmed and will not allow the same phone to be programmed twice in succession.
The minimum hardware requirements are a PC compatible 386 machine
with VGA graphics and a serial COM port, running MS–DOS 5.0 (or later
version).
Phone numbers can be allocated either from a file held on disc, allocated
sequentially from a starting number or by prompting the operator to enter
a number. If required, the phone number (NAM) programming can be
disabled.
A report file is generated, logging the telephone ESN’s and phone numbers allocated.
Labels containing ESN/phone number information and barcodes can be
automatically printed using a suitable printer.
If required the Short Code Memory (SCM) can be pre–programmed with
numbers from a specified data file.
Language selection is also possible when programming multi–language
telephones.
3. Getting started
3.1 Starting h6sub
Copy the files from the floppy disc onto your hard disc. At the DOS
prompt type ‘H6SUB’. The program will run and prompt you to select a
Original 11/98
Page 1 – 15
Page 16
NHX–7
PAMS
General Information and NAM Programming
configuration file. You will then be asked to select the number on one of
three allocation methods.
1.Prompt: By selecting this alternative you can give numbers.
The other numbers is taking from number prefix. The number
prefix is described in configuration file.
2.Auto–generate: In this alternative start number is 1111. The
user can change numbers too. If a new phone is connected
the next phone number is 1112.
3.No number: In this alternative phone programming failed.
The program is now ready to program telephones using the configuration
selected, or alternatively, if no telephone is connected, the configuration
and/or data files may be modified using the softkeys provided.
Technical Documentation
3.2 Command Line Options
To view the available command line options type ‘h6sub –?’.
Command line format is ‘h6sub {options} {filename} options:
–P{1:2:3:4} Selects COM port number (Default is COM1)
–E Disables file editing function keys.
–Snnnnn Sets default security/lock code (Default is 12345).
–? –H Shows this help.
–Txxxx or Nxxxx: Force h6sub to load product file Txxxx or Nxxxx.
filename: Name of configuration file to load on startup.
3.3 User Display
The main display (Configuration) shows the current configuration of the
program in the upper left hand side of the window. If a telephone number
file is being used its status is shown in the upper right hand corner of the
window. There is name information, how many numbers is in the file, how
many is used and how many is left.
The status of the program is shown at the bottom of the window in yellow,
with error messages being displayed in red. Above the status box is
shown the currently selected number allocation method.
The ESNs of the last telephone programmed and the currently connected
telephone are shown at the left hand side of the window.
3.4 User Softkeys
The softkeys F1 to F9 can be used to configure the program to the users
requirements and to modify various data files used by the program. Every
dialog you can move with (Up–down–left–right) arrow buttons.

F8 Edit Country
Allows the country data file to be modified.
F9 Exit
Exits the program and returns to DOS.
4 Program configuration files
4.1 Parameter Selection
Using function keys F2, F3 and F4 a selected configuration file ‘*.cfg’ can
be loaded, modified and stored for future use.
In the ‘Edit Configuration’ window the cursor position can be moved up
and down the list of parameters using the ‘cursor up’, ‘cursor down’, ‘tab’
and ‘<shift>tab’ keys.
Once the desired parameter is highlighted, the value/setting may be modified by using the ‘cursor left’ and ‘cursor right’ keys
If pre–defined options are available, or by simply entering a new value or
name as required.
4.2 Security Code Allocation
The program can be configured to take the security/lock code from a plain
text file ‘*.sec’ held on disc by setting the ‘Security code’ field to ‘<FROM
Original 11/98
Page 1 – 17
Page 18
NHX–7
PAMS
General Information and NAM Programming
FILE>’ and providing a filename in the ‘Security code file name’ field. This
file will contain a random list of numbers.
The security/lock code is selected from the file using the following algorithm:
1. Adds the last 6 digits of the phone number to the number of
lines in the file.
2. Divides the result by the number of lines in the file.
3.The remainder is the line number in the file from which the
code is selected.
The utility ‘sec_gen.exe’ may be used to generate a file of 450 random
security codes.
If the ‘Security code’ field is set to ‘<FROM MIN>’ the code programmed
into the telephone will be the last 4/5 digits of the phone number in reverse order.
The third option allows a fixed code to be programmed into all phones.
This number is defaulted to ‘12345’, but can be set as desired using the
–S command line option.
Technical Documentation
4.3 Phone Number Allocation
Phone numbers can be allocated from a plain text file ‘*.tel’ held on disc
by setting the ‘Read numbers from file’ field to YES (in configuration file)
and providing a filename in the ‘Input numbers file name’ field.
The configuration is set by pressing the ‘Enter’ key.
If phone numbers are not being read from a file you will now be prompted
to choose between automatic sequential numbering, manual entry of a
number at programming time, or no number programming.
See section 3.1. Starting h6sub for details.
4.4 NAM Verification
The edit configuration window provides an option for verification of the
number programmed into the telephone, the ‘Verify NAM’ field.
If set to ‘YES’ the phone number will be read back from the telephone on
completion of NAM programming and compared to the number allocated.
If required the field can be set to ‘NO’ in order to reduce the overall programming time.
5 INPUT FILES
5.1 Configuration File
The configuration file ‘*.cfg’ is used to store the user’s preferred settings
Page 1 – 18
Original 11/98
Page 19
PAMS
NHX–7
Technical Documentation
for h6sub. Many different configurations may be saved. The user is
prompted to select a configuration file to load on startup. The configuration may be modified by selecting softkey F3. New configurations may be
stored by selecting softkey F4.
NOTE ! If you modify ’*.cfg’ file, phone is not connected to m–bus. After
modify stop the h6sub program, connect phone and start program again.
5.2 NAM Data and Country Data
In order to generate the required NAM data the program draws data from
the ‘country.dat’ file and ‘tacs.nam’ files.
These files can be modified using softkeys F7 for the NAM data file, and
F8 for the country data file. Modification of parameters is achieved using
the same method as used in the ‘Edit configuration’ window.
The next and previous entries in the file can be viewed by moving the cursor to the ‘Edit next entry’/‘Edit previous entry’ field and pressing ‘Return’.
General Information and NAM Programming
5.3 Software Version Files
In order to communicate with the telephone the program needs to load a
‘software version file’ for the telephone currently connected. These files
have the extensions ’*.nhx’ for TACS telephones.
For NHX7* series telephones these files do not change with different issues of a particular software product. Therefore the filenames of the software version files take the format ‘{product}.nhx’. For example;
‘nhx–7.nhx’ for NHX–7 software, any version.
These files will be provided as required by NMP Ltd.
5.4 Telephone Number File
H6sub requires the ‘*.tel’ telephone number file to be an ASCII text file
with the following format:
nnnnnnnnnn<CR><LF>
where ‘nnnnnnnnnn’ is the 10 digit phone number, terminated with a car-
riage return, line feed.
Deviation from this format may result in phones being programmed with
invalid NAM data.
It is NOT allowed to use a word processor to generate this file.
5.5 Security Code File
H6sub requires the ‘*.sec’ security code file to be an ASCII text file with
the following format:
nnnnn<CR><LF>
Original 11/98
Page 1 – 19
Page 20
NHX–7
PAMS
General Information and NAM Programming
where ‘nnnnn’ is the 5 digit security code, terminated with a carriage return, line feed. Only 4 digits of them are used if phone has 4 digit security
code.
Deviation from this format may result in phones being programmed with
invalid NAM data.
It is NOT allowed to use a word processor to generate this file.
6 DATABASE FILES
6.1 Numbers Database
The ‘numbers’ database (*.nos) file is created from the specified telephone numbers file (*.tel). When programming telephones the next available number is taken from the *.nos file and the entry in the file is marked
as ‘used’.
The status of the contents of the *.nos file is shown at the top right hand
side of the display during programming. When the database is exhausted
an error message is displayed. A new *.tel file must then be specified.
Technical Documentation
7 OUTPUT files
7.1 Report File
A ‘*.rpt’ report file is generated by the program and updated as each telephone is programmed. The file contains the ESN of the telephone (in decimal format), the phone number allocated and the security/lock code, all
delimited by a single space character.
ee/ee/ee/eeeee<SP>nnnnnnnnnn<SP>sssss <CR><LF>
This is the file which would normally be used for dispatch to the customer.
7.2 ESN File (TACS only)
The file contains the ESN of the telephone (in decimal format, with no
slashes) followed by the PIN ID associated with the PIN code programmed into the telephone, delimited by a single space character.
eeeeeeeeeee<SP>ddddddddddd<CR><LF>
This is the file which would normally be used for dispatch to the service
provider.
8 Label printing
On successful programming of a telephone the program will automatically
print two labels;
1. A user guide label :– containing the phone number and security/lock code,
Page 1 – 20

PAMS
NHX–7
Technical Documentation
2. A box label :– containing the ESN and a code 39 barcode
representation of the phone number.
The program can be configured to work with various types of label stationary using the softkey F6. The printing of numbers can also be suppressed using this configuration window.
The recommended printer is the Canon BJ300 which offers sprocket
feeding of continuous label stationery.
