Operation Modes
The transceiver has five different operation modes:
– Power off
– Idle
– Active
– Charge
– Local
In the Power off mode only the circuits needed for power up are supplied.
In the Idle mode circuits are powered down and only sleep clock is run-
ning.
In the Active mode all the circuits are supplied with power altough some
parts might be in the idle state part of the time.
NSW-5
System Module UT5U
The Charge mode is effective in parallel with previous modes. The charge
mode itself consists of two different states, i.e. the charge and the maintenance charge mode.
The Local mode is used for testing and alignment.
Active Operation
The phone has the following Active Operation modes:
– Analog mode, on 800 MHz band
– Analog Control ChannelACCH
– Analog Voice ChannelAVCH
– Digital mode, on 800 MHz band
– Digital Control ChannelDCCH
– Digital Traffic ChannelDTCH
– Digital mode, on 1900 MHz band
– Digital Control ChannelDCCH
– Digital Traffic ChannelDTCH
– Out Of Range –mode OOR
If the phone cannot find signal from the base station on any control chan-
nel (analog or digital) it goes into OOR mode for power saving.
Analog Control Channel mode (ACCH)
On analog control channel the phone receives continuous signalling messages on Forward Control Channel (FOCC) from base station, being
most of the time in IDLE mode. Only the receiver part is on. Occasionally
phone re–scans control channels in order to find the stronger or other-

wise preferred control channel. Also registration (TX on) happens occasionally, where phone sends its information on Reverse Control Channel
(RECC) to base station and the phone’s location is updated in the switching office.
If a call is initiated, either by the user or base station, the phone moves to
analog voice channel or digital traffic channel mode depending on the orders by the base station.
Analog Voice Channel Mode (AVCH)
The phone receives and transmits analog audio signal. All circuitry is
powered up except digital rx–parts. In this mode DSP does all the audio
processing, and in the Hands Free (HF) mode it also performs echo–cancellation and the HF algorithm. COBBA makes AD–conversion for MIC
signal, and DA–conversion for EAR signal.
With audio signal also SAT (Supervisory Audio Tone) is being received
from the base station. The SAT signal can be 5970 Hz, 6000Hz or 6030
Hz, the frequency being defined by the base station. DSP’s DPLL phase
lock loops to SAT, detects if the SAT frequency is the expected one and
examines the signal quality. DSP reports SAT quality figures to MCU regularly. The received SAT signal is transponded (transmitted back) to base
station.
PAMS Technical Documentation
Base station can send signalling messages on Forward Voice Channel
(FVC) to the phone, by replacing the audio with a burst of Wide Band
Data (WBD). Typically these are handoff or power level messages. System Logic RX–modem is used for receiving the signalling message burst,
after which it gives interrupt to MCU for reading the data. During the burst
audio path must be muted; MCU gives message to DSP about this. MCU
can acknowledge the messages on Reverse Voice Channel (RVC), where
DSP sends the WBD to transmitter RF.
Digital Control Channel Mode (DCCH)
On digital control channel (DCCH) the DSP receives the paging information from the Paging channels. DSP sends messages to MCU for processing them.
Phone uses sleep mode between received time slots. Then DSP sets the
sleep clock timer and MCU, DSP and RF including VCXO are powered
down. Only sleep clock and necessary timers are running.
From DCCH phone may be ordered to analog control channel or to analog or digital traffic channel.
Digital Traffic Channel Mode (DTCH)
Page 14
On digital voice channel the DSP processes speech signal in 20 ms time
slots. DSP performs the speech and channel functions in time shared
fashion and sleeps whenever possible. Rx and tx are powered on and off

PAMS Technical Documentation
according to the slot timing. MCU is waken up mainly by DSP, when
there is signalling information for the Cellular Software.
In Digital Data Channel Mode audio processing is not needed and the audio circuitry can be shut down. Otherwise the mode is similar to Digital
Voice Channel Mode.
Out of Range Mode (OOR)
If the phone cannot find signal from the base station on any control channel (analog or digital) it can go into OOR mode for power saving.
All RF circuits are powered off and baseband circuits are put into low
power mode, VCXO is stopped and only sleep clock is running in MAD
and CCONT. After the programmable timer in MAD has elapsed the
phone turns receiver on and tries to receive signalling data from base station. If it succeeds, the phone goes to standby mode on analog or digital
control channel. If the connection can not be established the phone will
return to out of range mode, until the timer elapses again.

Power Distribution
In normal operation the baseband is powered from the phone‘s battery.
An external charger recharges the battery. The charger can be either a
standard charger that can deliver around 350 mA or so called performance charger, which can deliver supply current up to 850 mA.
The baseband contains components that control power distribution to
whole phone excluding those parts that use continuous battery supply.
The battery feeds power directly to following parts of the system: CCONT,
power amplifier, and UI (buzzer, display, keyboard lights, IR and vibra).
Figure below shows a block diagram of the power distribution.
The power management circuit CHAPS provides protection agains overvoltages, charger failures and pirate chargers etc. that would otherwise
cause damage to the phone.

VR1, VBB, V2V, VR6 and Vref in power–up.
VBB is used as baseband power supply for all digital parts. It is constantly
on when the phone is powered up. VSIM is used as programming voltage for the Flash memory when SW is writing a backup of EEPROM data
during power–down with the power key.

PAMS Technical Documentation
V5V is used for RF parts only. It can be switched off by the RFCEN signal.
VR1 is used for the VCXO supply, and VR6 is used in COBBA for analog
parts. RFCEN signal to CCONT controls both VR1 and VR6 regulators;
they can be switched off in sleep modes, and during standby. During
sleep VR6 output pin is connected to VBB regulator inside CCONT.
CCONT regulators are controlled either through SIO from MAD or timing
sensitive regulators are controlled directly to their control pins. These two
control methods form a logical OR–function, i.e. the regulator is enabled
when either of the controls is active. Most of the regulators can be controlled individually.
CHAPS connects the charger voltage (VCHAR) to battery. MCU of MAD
controls the charging through CCONT. MAD sets the parameters to
PWM–generator in CCONT and PWM–output controls the charging voltage in charger.
When the battery voltage is below 3.0V, CHAPS controls independently
the charging current.

Charging Control
Charging is controlled by MCU SW, which writes control data to CCONT
via serial bus. CCONT output pin PWMOUT (Pulse Width Modulation)
can be used to control both the charger and the CHAPS circuit inside
phone. Charging control diagram below.

Two–wire charging
With 2–wire charging the charger provides constant output current, and
the charging is controlled by PWMOUT signal from CCONT to CHAPS.
The PWMOUT signal frequency set is 1 Hz, and the charging switch in
CHAPS is pulsed on and off at this frequency. The final charged energy to
battery is controlled by adjusting the PWMOUT signal pulse width.

Both the PWMOUT frequency is selected and the pulse width controlled
by the MCU which writes these values to CCONT.
Three–wire charging
With 3–wire charging the charger provides adjustable output current, and
the charging is controlled by the PWMOUT signal from CCONT to charger, with the bottom connector signal. The PWMOUT signal frequency
set is 32 Hz, and the charger output voltage is controlled by adjusting the
PWMOUT signal pulse width. The charger switch in CHAPS is constantly
on in this case.

Both MAD and CCONT include a watchdog, and both use the 32 kHz

MAD gives reset to MAD. After the reset the MCU can read an internal
status bit to see the reason for reset, whether it was from the MAD or
CCONT. The SW–watchdog delay can be set between 0 and 63 seconds

MAD must reset CCONT watchdog regularly. CCONT watchdog time can
be set through SIO between 0 and 63 seconds at 1 second steps. After
power–up the default value is 32 seconds. If watchdog elapses, CCONT
will cut off all supply voltages.
After total cut–off the phone can be re–started through any normal power–up procedure.

Power up
When the battery is connected to phone, the 32.768 kHz crystal oscillator
of the CCONT is not started until the power–button is pressed. The regulators are not started. After the crystal has started, the phone is ready to
be powered up by any of the following ways.

After the PWR–key has been pushed, the CCONT gives PURX reset to

(if the battery voltage has exceeded 3.0 V). VR1 supplies VCXO, VBB
supplies MAD and digital parts of COBBA, and VR6 supplies analog parts
of COBBA. After the initial delay t2 the VCXO starts to give proper RFC
to COBBA that further divides it to the COBBACLK for MAD. COBBA will
output the COBBACLK only after the PURX reset has been removed. After delay t3 the CCONT releases PURX and MAD can take control of the
operation of the phone.

The power up procedure is similar to process described in the previous

Also CCONT sets output CCONTINT. MAD detects the interrupt, and after
that reads CCONT status register to find out the reason for the interrupt
(charger in this case). The phone will remain in the ”acting dead” state,
which means that the user interface is not activated unless the power button is pressed. Only the charging activity is indicated on the display.

Before battery voltage voltage rises over 3.0 V CHAPS gives an initial
charge (with limited current) to the battery. After battery voltage reaches
that voltage limit the power up procedure is as described in the previous
chapters.
Anyway, if the standard charger is connected and power–up requested
from the power button, the current consumption is kept in the minimum in
the beginning because the charger output current is rather low and the
battery voltage is on the minimum limit. Thus, the phone receiver parts
and the user interface lights are not powered up immediately, but after a
short delay.

IBI (Intelligent Battery Interface)
Phone can be powered up by external device (accessory or similar) by
providing a start pulse to the battery signal BTEMP; this is detected by
CCONT. After that the power–up procedure is similar to pushing power–
button.
Mixed trigger to power up
It is possible that PWR–key is pushed during charger initiated power–up
procedure or charger is connected during PWR–key initiated power up
procedure. In this kind of circumstances the power–up procedure (from
the HW point of view) continues as nothing had happened.
When the Baseband HW is working normally and SW is running, SW detects that both conditions are fulfilled and then acts accordingly.
PAMS Technical Documentation
Power Down
Controlled Power Down
Power down pushing PWR–key
MAD (MCU SW) detects that PWR–key is pressed long enough. After that
the lights and LCD are turned off. MCU stops all the activities it was doing
(e.g. ends a call), sends power off command to CCONT (i.e. gives a short
watchdog time) and goes to idle–task. After the delay CCONT cuts all the
supply voltages from the phone.
Note that the phone does not go to power off (from HW point of view)
when the charger is connected and PWR–key is pushed. It is shown to
user that the phone is in power off, but in fact the phone is just acting being powered off (”acting dead”).
Power down when battery voltage is discharged too low
During normal discharge the phone indicates the user that the battery will
drain after some time. If not recharged, SW detects that battery voltage is
too low and shuts the phone off through a normal power down procedure.
Anyway, if the SW fails to power down the phone, the CCONT will make a
reset and power down the phone if the battery voltage drops below 2.6 –
2.9 V.
Power down with fault in the transmitter
If MAD receives fault indication, from the line TXF, that the transmitter is
on although it should not be, the control SW will power down the phone.

Uncontrolled Power Down
NSW-5
System Module UT5U
Power down
when watchdog expires
If the SW fails to update the watchdog, the watchdog will eventually expire and CCONT cuts all the supply voltages from the phone.
Power down with Battery disconnected
When battery is disconnected, immediate and totally uncontrolled power–
down happens. Therefore a power off procedure in this case can not be
described. One possible risk is that if the MCU is writing something to
Flash exactly at the same moment, the memory contents may be corrupted.
Battery disconnected when charger is connected
From hardware point of view the phone could otherwise continue functioning normally, but if the charger voltage is higher than the maximum
allowed battery voltage, this can damage the RF parts. Therefore, there
must be hardware protection against this in CHAPS.
If the user presses the PWR–key, the phone can wake up to detect that
the battery is not present (no BTYPE and /or BTEMP). After that the
phone either turns itself off or goes to low current mode (can be decided
by MCU SW).
This state does not harm the phone. The phone can not be used only
from the charger without the battery.

Circuit Description of Submodules
CTRLU
CTRLU comprises MAD ASIC (MCU, DSP, System Logic) and Memories.
The soldering connections of the IC are unaccessible for probing, only
test points can be used. Therefore no pin list is published.
The environment consists of two memory circuits (FLASH,SRAM), a
22–bit address bus and a 16–bit data bus. Besides there are
ROM1SELX, ROM2SELX and RAMSELX signals for chip selection.
MCU main features
– System control
PAMS Technical Documentation
– Cellular Software (CS)
Cellular Software takes care of communication with switching office,
as well call build–up, maintenance and termination.
– Communication control
M2BUS is used to communicate to external devices. This interface is
also used for service and maintenance purposes.
Serial interface from MAD to LCD (common for CCONT).
– Authentication
Authentication is used to prevent fraud usage of cellular phones.
– RF monitoring
RF temperature monitoring by VCXOTEMP, ADC in CCONT.
Received signal strength monitoring by RSSI, ADC in CCONT.
False transmission detection by TXF signal, digital IO–pin.
– Power up/down and Watchdog control
When power key is pressed, initial reset (PURX) has happened and default regulators have powered up in CCONT, MCU and DSP take care of
the rest of power up procedures (LCD, COBBA, RF).
MCU must regularly reset Watchdog counter in CCONT, otherwise
the power will be switched off.
– accessory monitoring
Accessory detection by EAD (XMIC/HEADSETINT), AD–converter in
CCONT.

PAMS Technical Documentation
– battery and charging monitoring
MCU reads the battery type (BTYPE), temperature (BTEMP) and voltage
(VBAT) values by AD–converter in CCONT, and phone’s operation is allowed only if the values are reasonable. Charging current is controlled by
writing suitable values to PWM control in CCONT.
MCU reads also charger voltage (VCHAR) and charging current values
(IBAT).
– production/after sales tests and tuning
Flash and EEPROM loading, baseband tests, RF tuning
– Control of CCONT via serial bus
MCU writes controls (regulators on/off, Watchdog reset, charge
PWM control) and reads AD–conversion values.
For AD–conversions MCU gives the clock for CCONT (bus clock),
because the only clock in CCONT is sleep clock, which has too low frequency.
NSW-5
System Module UT5U
DSP main features
The DSP (Digital Signal Processor) is in charge of the channel and
speech coding according to the IS–136 specification. The block consists
of a DSP and internal ROM and RAM memory. The input clock is 9.72
MHz, and DSP has an own internal PLL–multiplier. Main interfaces are to
MCU, and via System Logic to COBBA and RF.
– Analog transmit
Audio signal in analog mode is fed to the COBBA codec, where it is
routed, amplified and converted by internal A/D converter into bitstream
(the sample rate is in digital mode 8.0 kHz and in analog mode 8.1 kHz).
The digitized speech is processed by the DSP audio modules into 48.6
kHz audio. This audio is FM modulated into I/Q samples at 97.2 kHz. The
samples are sent via System Logic transmit buffer to the COBBA TXI/Q
D/A converters. This I/Q modulated analog signal goes then to RF unit
I/Q inputs. DSP must also perform echo cancelling in HF mode.
– Analog receive
In analog receive the signal is demodulated by DEMO (block in COBBA)
and the sample rate is 48.6 kHz. The samples are directed trough System Logic to DSP. DSP performs audio processing and finally transfers
the digital audio (8.1 kHz sample rate) back to COBBA, where they are
D/A converted. Resulting audio signal is routed and amplified to the earpiece or external loudspeaker.
– Digital transmit
In digital transmit mode DSP processes speech data in 20 ms slots. It
performs speech encoding (EFR), CRC generation, convolutional coding
and interleaving. Finally it sends the symbols to the System Logic modulator. The modulator performs the π/4 DQPSK modulation. System Logic

controls the transmit timing and at specified intervals sends the I/Q samples at 97.2 kHz to COBBA for TXI/Q D/A converters.
– Digital receive
In digital receive mode the second IF is 450 kHz, which is sampled at
194,4 kHz in COBBA, aliased to 61,2 kHz and then downconverted and
demodulated in DSP. The timing is controlled by System Logic. DSP performs bit detection with equalizer and then convolutional decoding and
CRC checking. After this the (speech) bits are passed for speech decoding (EFR). The decoded bits are converted to analog signal in COBBA,
then routed and fed to the earpiece.
– Analog modem functions
On the analog voice channel, DSP performs the signalling functions: SAT
receiving and transponding. Transmit function: ST and wide band data.
– Control and general functions
In all modes DSP controls the RF. Controlling is done physically through
System Logic, where all necessary timing functions are implemented, and
control I/O lines are provided for e.g. synthesizer loading, power control
etc.
PAMS Technical Documentation
In all transmit modes DSP takes care of the transmitted power control
(TXC) and frequency control (AFC). Also DTMF tone generation is made
in DSP.
All clocks and timing are generated from the RFC clock. In sleep mode
only the 32 kHz clock is used.

A slow speed DA–converter provides automatic frequency control (AFC).
In addition, there is a DA–converters for transmitter power control (TXC).
COBBA also passes the RFC (19.44 MHz) to MAD as COBBACLK (9.72
MHz).
COBBA is connected to MAD via two serial busses:
– RXTXSIO, for interfacing the RF–DACs and DEMO; and also for audio
codec and general control. Signals used: COBBACLK (9.72 MHz, from
COBBA), COBBACSX, COBBASD (bi–directional data) and COBBADAX (data ready flag for rx–samples).
– Codec SIO, for interfacing the audio ADCs / DACs (PCM–samples).
A vibra alerting device is used for giving silent signal to the user of an incoming call. The device is controlled with a VibraPWM output signal from
MAD. The vibra alert can be adjusted either by changing the pulse width
or by changing the pulse frequency.
CCONT Main Features
CCONT generates regulated supply voltages for baseband and RF.
There are seven 2.8 V linear regulators for RF, one 2.8 V regulator for
baseband, one special switched output (VR1_SW), one programmable 2

asyncronous databus. IR databus is the same as used for FBUS data
transferring. Thus FBUS Tx and Rx lines must be turned to IR mode. The
IR mode can be selected from user interface.
The module is activated with the IRDAEN signal by MAD, which supplies
power to the IR module (N350) and enables supply current for IR leds.
The IR datalines are connected to MAD accessory interface AccIf via
FBUS. The RX and TX lines are separated from FBUS by 3–state buffer
(D350), when the IR–module is switched off. The AccIf performs pulse
encoding and shaping for transmitted data and detection and decoding
for received data pulses.
The data is transferred over IR link using serial FBUS data at speeds 9.6,
19.2, 38.4, 56.6 or 115.2 kbits/s, which leads to maximum troughput of
92.160 kbits/s. The used IR module complies with the IrDA SIR specification (Infra Red Data Association).

regulators VR1–VR7 are reserved for the RF blocks. VR7_bias controls
the 800MHz PA bias to boost better efficiency in analog mode and at
power levels 6 to 10 in digital mode. V5V voltage is used for the PLL

The receiver is a double conversion receiver. Most of the RX functions
are integrated in two ICs, namely receiver front end and EROTUS. Receiver front end contains a LNA and the 1st mixer. Analog and digital IF–
parts are integrated in the EROTUS.
Nokia Mobile Phones Ltd.

PAMS Technical Documentation
The received RF signal from the antenna is fed through a duplex filter to
the receiver unit. The signal is amplified by a low noise preamplifier. In
digital mode the gain of the amplifier is controlled by the AGC2 control
line. The nominal gain of 15 – 20 dB is reduced in the strong signal
condition about 14 – 19 dB (in digital mode). After the preamplifier the
signal is filtered with a SAW RF filter. The filter rejects spurious signals
coming from the antenna and spurious emissions coming from the mixer
and IF parts.
The filtered RF–signal is downconverted by an active mixer. The frequency of the first IF is 116.19 MHz. The first local signal is generated in
the UHF synthesizer. The IF signal is fed through a SAW IF–filter. The
filter rejects intermodulating signals and the second IF image signal. The
filtered 1st IF is fed to the receiver section of the integrated RF circuit
EROTUS, which has separate IF paths for analog and digital modes of
operation.
In digital mode the IF1 signal is amplified by an AGC amplifier, which has
a gain control range of 57 dB. The gain is controlled by an analog signal
with AGC1–line. The amplified IF signal is down converted to a second
IF in the mixer of EROTUS. The second local signal is the 6th overtone of
the 19.44 MHz VCTCXO. LO frequency multiplier is implemented in two
stages. First multiplication by 3 is done with a EROTUS multiplier with an
external trap and the second multiplication by 2 is done in the integrated
doubler in EROTUS.
NSW-5
System Module UT5U
The second IF frequency is 450 kHz. The second IF is filtered by two ceramic filters. The filter rejects signals on the adjacent channels. The filtered second IF is fed back to EROTUS, where it is amplified and fed
balanced out to COBBA_D via IF2D lines.
In analog mode the filtered and amplified IF1 signal is fed to a mixer. This
mixer has been optimized for low current consumption. After this the
mixer down converted signal is fed through the same IF2 filter as in digital
mode and finally it is amplified in the limiter amplifier. The limited IF2 signal is fed via balanced IF2A lines to COBBA_D, which has a digital FM–
detector. The limiter amplifier produces also a RSSI voltage for analog
mode field strength indication.
TDMA 1900 RX
On 1900 MHz band the receiver operates only in digital mode. There is a
separate front end for this band. IF–parts are common for both bands.
Operation of the receiver is similar to digital mode operation on 800 MHz
band.
Frequency Synthesizers
The stable frequency reference for the synthesizers and base band circuits is a voltage controlled temperature compensated crystal oscillator
VCTCXO. Frequency of the oscillator is 19.44 MHz. It is controlled by an
Issue 1 10/00
Nokia Mobile Phones Ltd.

System Module UT5U
AFC voltage, which is generated in the base band circuits. In digital mode
operation, the receiver is locked to base station frequency by AFC. Next
to detector diode, there is a sensor for temperature measurement. Voltage RFTEMP from this sensor is fed to baseband for A/D conversion.
This information of the RF PA–block temperature is used as input for
compensation algorithms.
The ON/OFF switching of the VCTCXO is controlled by the sleep clock in
the baseband via RFCEN. Other parts of the synthesizer section are 1
GHz VCO, 2 GHz VCO, VHF VCO, PLL for 2 GHz VCO and PLL sections
of the EROTUS IC.
DAMPS 800 operation
1GHz UHF synthesizer generates the down conversion injection for the
receiver and the up conversion injection for the transmitter. UHF frequency is 985.20 ... 1010.16 MHz, depending on the channel which is
used. 1GHz UHF VCO is a module. The PLL circuit is dual PLL, common
for both UHF and VHF synthesizers. These PLLs are included in the
EROTUS IC.
PAMS Technical Documentation
LO signal for the 2nd RX mixer is multiplied from the VCTCXO frequency
as described above.
VHF synthesizer is running only on digital or analog traffic channel.
322.38 MHz signal (divided by 2 in EROTUS) is used as a LO signal in
the I/Q modulator of the transmitter chain.
TDMA 1900 operation
2 GHz VCO with external PLL circuit generates 2046.24 ... 2106.18 MHz
injection signals for 1st RX mixer and TX upconverter.
VHF synthesizer is running only on digital traffic channel. Operating frequency 392.46 MHz is fed to EROTUS modulator, where it is divided by 2
and used as modulator LO signal.
Transmitter
DAMPS800 TX
The TX intermediate frequency is modulated by an I/Q modulator contained in the transmitter section of EROTUS IC. The TX I and TXQ signals are generated in the COBBA_D interface circuit and they are fed differentially to the modulator.
Page 36
Intermediate frequency level at the modulator output is controlled by
power control.
The output signal from EROTUS modulator is filtered to reduce harmonics and RX–band noise. The final TX signal is achieved by mixing the
UHF VCO signal and the modulated TX intermediate signal in an active

mixer. After the mixing TX signal is amplified by a driver stage. From
driver stage the signal is fed trough the TX filter to PA MMIC.
The PA amplifies the TX signal by 28–32 dB. Amplified TX signal is filtered in the duplex filter. Then signal is fed to the antenna, where the
maximum output level is typically 480 mW.
The power control loop controls the gain of the EROTUS gain control
stage. The power detector consists of a directional coupler and a diode
rectifier. The output voltage of the detector is compared to TXC voltage in
EROTUS. The power control signal (TXC), comes from the RF interface
circuit, COBBA_D. TXP signal sets driver power down to ensure off–burst
level requirements.
False transmission indication is used to protect transmitter against false
transmission caused by component failure. Protection circuit is in EROTUS. The level for TXF is set by internal resistor values in EROTUS.
Because of wide temperature range, it is neccessary to compensate the
effect of temperature on the output power. To monitor this environment

change, temperature measurement is done by using NTC resistor. A
Factor table is used for temperature compensation. The table values are
defined without factory measurements. Temperature is measured and
right compensation value is added to TXC–value. Requirement for compensation update is for every 1 minutes or after every 5°C of temperature
change. This means that the PL2 output power is reduced linearily 0.5dB
when temperature inside the phone rises from +55°C to+80°C.
Power Levels (TXC) vs. Channel
Duplexer frequency response ripple is compensated by software. Power
levels are calibrated on four channels in production. Values for channels
between these tuned channels are calculated using linear interpolation.
Power levels vs. Battery Voltage
To extend battery duration in digital mode, the output power is decreased
linearily from level 2 to –0.5 dB when battery voltage drops below 3.3V.
PAMS Technical Documentation
TX Power Up/Down Ramps
Transmitter output power up/down ramps are controlled by SW. A special
ramp tables are used for that. Requirement is for nine different ramps in
digital mode for both operating bands. Separate ramps are used in power
up and power down ramps.
Modulator Output Level
Maximum Pout level values:
–20dBm for power levels 2...5
–24dBm for power level 6
–28dBm for power level 7
–20dBm for power levels 8...10

Digital mode RSSI vs. input signal is calibrated in production, but RSSI
vs. RSSI vs. channel are compensated by software.

To run the After Sales SW, a parallel port software protection device
(PKD-1) has to be connected. TDF-4 box must connected to PC for
flashing purposes. The user can use PC-locals functions in modules for
testing NSW-5 mobile stations (MS). The test functions send test mes-
sages from PC to MS and receive results and show them in the PC dis-
play. The messages can be sent via M2BUS or FBUS.
Note: if this software is to be run on laptops, the power saving feature
MUST be switched off.
Hardware requirements for Windows 3.1x
The recommended minimum hardware standard to run Service Software
is any computer which is 386 33 MHz or greater with at least 4 MB of
memory and VGA type display (640 x 480). This assumes that only the
WinTesla with After Sales Support Modules is active, i.e. other Windows
packages are not running in the background.
PAMS Technical Documentation
Hardware requirements for Windows 95
The recommended minimum hardware standard to run Service Software
is any computer which has Pentium processor, memory 8 MB and meets
HW requirements recommended by Microsoft.
Software Environment of the Support Modules
The Service Software user interface is intended for the following environ-
ments: Microsoft Windows 3.1x (enhanced mode) and Windows 95envi-
ronment running in enhanced mode. Support for Microsoft NT may be
added, if required. Detailed information about Windows and application
usage can be found from the Microsoft Windows Version 3.1 Users Guide
chapter one (Windows Basics) and chapter two (Application Basics).
As an ordinary Windows application, the main idea in the user interface is
that selections are made with menus, push buttons and shortcut keys.
Selections can be done by using keyboard and/or mouse. There is always
a status bar displayed at the bottom of the main window which contains
information about current actions.

Note:A number of PC’s of an older generation use the Intel, National Semiconductor, or United
Microelectronics IC 8250 as the serial port UART. This is a comparatively inefficient circuit for current
purposes and does not necessarily support the M2BUS adapter at 9600 baud. The newer UART’s
NS16450 and NS16550AF of National Semiconductor offer solutions for these problems.

Installation
Mechanical Connections
Caution:Make sure that you have switched off the PC and the printer
before making connections.
Caution:Do not connect the PKD–1 key to the serial port. You may
damage your PKD–1 !
The software controls the phone via a separate adapter connected to the
serial port of the PC, and to the telephone’s M2BUS (DAU–9S).
Attach the dongle PKD–1 to the parallel port 1 (25–pin female D–connector) of the PC. When connecting PKD–1 to the parallel port, be sure that
you insert the computer side of the PKD–1 to the PC (male side). If you
use a printer on parallel port 1, install the PKD–1 between the PC and
your printer cable.
PAMS Technical Documentation
The PKD–1 should not affect devices working with it. If some errors occur
(errors in printing are possible) please try printing without the PKD–1. If
printing is OK without the PKD–1 please contact your dealer. We will offer
you a new PKD–1 in exchange for your old one.
Installing the Software on PC Hard Disk
The program is delivered on a diskette and is copy protected with a
dongle PKD–1. It must be present in parallel port when using Service
software.
The program can also be installed on the hard disk, which is recommended to obtain a maximal data access rate.
Keep the original diskette safe to enable upgrading of the program !
If you plan to use PCL Start service software, you must install it before
installing Service software, see the PCL Start installation instructions.
To install the new Service software program, follow the steps below:
1.insert the new Service software diskette
into drive A: of your computer
