Choose such a place for the phone holder in the vehicle that will be both easy

and safe when using the phone. Remember to leave enough space for the

antenna plug behind the phone holder. First, fix the installation base to the

place you have chosen, and then install the phone holder in the installation

base.

3.2.3 Microphone

Install the microphone so that it is aimed directly at the user, and comes as

close as possible to the user’s mouth. A good place for the microphone is near

the rearview mirror where the noise level is lower than, for example, beside a

windshield pillar. It is also possible to install the microphone on a sun visor, but

then it will be inconvenient to use the sun visor and microphone at the same

time. One alternative would be a swan-neck microphone as it can be placed

closest to the user’s mouth.

3.2.4 Cable

Obtain the necessary +-electricity from a suitable place, preferably directly

from the battery of the vehicle. Connect the fuse chamber to the +-wire. You

will find the fuse chamber in the installation material bag. Connect the ground

lead to the frame of the car with a short wire.

3.2.5 External Handset HDS-50

Install the external handset the same way as you installed the phone holder.

3.2.6 Car Box UDH-50

Place the car box out of sight inside the dashboard of the car or to another

place. First, connect the wires to the car box. Install the car box so, that the

heat sink has some space for cooling. The car box has holes which enable you

to fasten the car box with a cable tie. The installation material bag also contains

adhesive band fasteners.

3.2.7 Hf Speaker

Install the speaker in a suitable place near the floor of the car.To avoid echo

remember to pay attention to the position of the microphone as well.

3.3 HF-FUNCTION

Benefon Sigma Gold offers you two different hands free -setups for the Car Kit

and Office Set: the background noise tuning (CAR KIT/OFFICE SET TUNING)

and MIC-ERP contrast tuning (CAR KIT/OFFICE SET SWING).

3.3.1 CAR KIT TUNING/OFFICE SET TUNING (theory)

You can set up the activation level of the microphone by using the CAR KIT

TUNING option. The level is correct when the microphone path is activated by

voice alone, and not, for example, by background noise in your car or office.

The following figure shows you the CAR KIT TUNING setup process. You can

set up the OFFICE SET TUNING following the same procedure.

a. If the CAR KIT TUNING is set too high, your voice (1) will not activate the

microphone path properly, and the person at the other end will only hear

interrupted transmission of speech.

b. If the CAR KIT TUNING has been set up too low, the background noise in

your car (2) will activate the microphone path, and the volume of the HF-

speaker will be low.

3.3.2 CAR KIT SWING/OFFICE SET SWING (theory)

The four-step CAR KIT SWING/OFFICE SET SWING tuning is used to set the

contrast of the microphone amplification/speaker attenuation swing. In the

following figures the swing position while listening to the Car Kit or Office Set is

indicated by a solid line and the position while speaking into Car Kit or Office

Set the indicated by a dotted line.

a. With a tuning value of 4 it is possible to obtain the smallest difference

between the amplification and attenuation of the microphone and speaker. This

means that the connection is almost bidirectional. If the HF-function easily

creates feedback, decrease the value of the CAR KIT SWING/OFFICE SET

SWING. By turning down the volume it is possible to reduce the occurance of

feedback.

4.0 SERVICE APPLICATIONS

4.1 BeneWin SCA-50

The BeneWin SCM Program for Windows is designed to facilitate maintenance of

phone numbers and user settings on Benefon mobile phones. You can also use your

phone to carry out the commands in the BeneWin Program, but it is handier to pro-

cess data using your screen and keyboard - the advantage of the BeneWin Pro-

gram. For example, all user settings are displayed in a single window, which enables

you to check at a glance your current settings.

Your personal settings and phone numbers stored on the hard disk can be trans-

ferred to the mobile phone whenever necessary. When you travel or use a borrowed

phone, your own settings make the phone feel like your own.

The main functions of the BeneWin Program are divided into two windows: the

BeneWin SCM window, in which you can modify the phone numbers, and the User

window, in which you can modify the phone’s user settings.

4.1.1 Installation of BeneWin program

5.1.4.1 CPU

I304 is itself a processor circuit. It is comprised of CPU, 512*8bit EEPROM,

timers, A/D converters, and both series- and parallel I/O lines. The clock

oscillator is located in the audio circuit and provides the CPU with a 7.2 MHz

clock signal. The CPU divides this by 4 to get timing signal E.

When the processor is operating, RESET = 5V, VCC = 5V, E = 1.8 Mhz, AS, R/

W and A0...A15 pulses should be 0/5V (no intermediate values, only 0 or 5V).

Product: TDP-52-SN3 (Sigma Gold) / OA0701 Processor

27.1.1999

5.1.4.2 Memories

Memory and external I/O-circuit address coding is done with the ASIC circuit

I305. The circuit options CSR, CSP, and OE are 0-active.

The program memory is in 256k*8 EPROM. The program uses the addresses

2100H...FFFFH. Page selection makes available another similar memory

block.

RAM-memory is 8k*8 CMOS RAM at the addresses 0000H...1FFFH. RAM

receives its power supply from its own regulator which is always operating,

even when the radio is in the OFF state.

5.1.4.3 The Modem

The FFSK modem is located in the audio circuit. The modem is connected to

the CPU by a series line, input to synchronised port, and transmission is

controlled by an ASIC series output. The modem gives a 1200 Hz signal

RXCLK to the processor and TXCLK to ASIC. There is a data detector within

the modem, the speed of which is controlled by C438.The CPU A/D converter

measures the level of acceptance from ERPDET line. The same detector also

serves to control the HF function.

5.1.4.4 AFC

The AFC function is performed by an internal ASIC frequency counter. A 450

kHz intermediate frequency is amplified to a square-wave form by Q305. The

frequency is adjusted by ASIC pulse frequency modulated signal D/A 0, which

is integrated by C378. This approx. 2.5V DC voltage is fed to the synthesiser

AFC pin.

5.1.4.5 Sleep Timer

The phone puts the central functions to sleep for a time. Although everything

seems normal to the user, most of the functions are closed down. The radio

and audio units are closed down completely. The processor still has a power

supply, but the processor is halted and has minimal power consumption. Only

the ASIC circuit sleep timer and its 32 kHz crystal oscillator remain in active

mode. The phone is "woken up" by interrupting the sleep timer or by changing

the keyboard state. The sleep timer 32 kHz clock freqency is produced by the

oscillator made by crystal X305.

5.1.4.6 Warm Start

C352 and R352 measure the length of a voltage break. The voltage drops

during a break, after which it is measured by the A/D convertor. The time

constant is approx. 10 s . Thus a "warm start" is detected.

27.1.1999

5.1.4.7 RESET

The processor voltage regulator ERROR output resets (stops) the processor

and zeroes the controls when the battery voltage drops below 5V. When the

voltage rises again, the processor restarts.

5.1.4.8 Power Switch

The power switch (PWRKEY) is grounded, and directs the regulator I201 to

conduct when pressed. The program commences and checks the PWRSW line

to ensure that the switch is being pressed, and sets hold on the regulator for

the PWRON line. When the switch is depressed for a longer time, the program

directs power to the PWROFF line. During a short voltage break, C211 and

R211 remember the previous control, i.e. fet Q202 conducts again when the

voltage is restored within 10 seconds. The switch-fet also serves as a watch-

dog should the voltage drop or processor error-state continue; after 10

seconds, the radio will shut down completely.

Note! The RAM and ASIC circuits have their own regulator connected to the

battery to ensure an uninterrupted power supply. RAM power supply is

ensured during a battery-pack change by the battery B201.

5.1.4.9 Battery Voltage Measurement

The battery voltage is measured by an A/D converter. The converter 256 step

conversion scale is not sufficient as it stands, so the measured range is

restricted to 5...8V by the operational amplifier I303. The reference voltage for

the measurement is provided by the processor regulator 5V supply. Calibration

is done by the program against a precisely known battery voltage.

5.1.4.10 I/O ports

The ASIC I/O ports PA...PF are 8-bit hold circuits. DATA is fed to the

addressed output. When the RESET line is down (0V) all the ASIC ports are

zeroed (0V). As RESET rises again, all of the two-way I/O ports are inputs until

the program sets them to the desired state. With the radio in OFF state,

RESET is down so all of the controls are also down although ASIC is still

provided with operational voltage (VRAM).

5.1.4.11 SIS

SIS functions are provided by a mask-programmed single chip processor I503

(68HC11A8). It communicates with the host processor via ASIC with an RS232

bus (5V levels). The circuit operation is not externally visible as it is a single-

chip solution. User specific information is stored in EEPROM which CANNOT

be read from outside the chip. All external attempts to read the information

clear both EEPROM and RAM (fill with FF).

5.1.4.12 Power Adjustment

The transmitter control logic switches TX power and also adjusts it to the

correct level. The STX_REG signal sets the transmitter to ready mode. Power

is controlled by the ASIC analog output D/A 1. It is a pulse frequency

modulated output which is converted to a DC voltage by integrating it with

C379. 0V corresponds to "no power" state, and 5V to maximum transmitter

power. The power levels are calibrated by the program at the source of

measurement.

5.1.4.13 Charging Control

The charger is controlled by the program. The charger is detected by a voltage

at the SV-CHG pin. The charging current (0...1,5A) is controlled by an analog

(0...5V) CHGCONT signal which comes from the ASIC D/A 2 pulse frequency

output. Charging is governed by the battery and radio temperatures, battery

voltage, and time measurement.

5.1.4.14 Temperature Measurement

The radio has two separate temperature sensors, one within the battery pack,

and the other within the radio module. Inside the radio the NTC resistor R316

voltage is measured by the processor A/D converter. This value is converted

by a programmed table to a temperature reading.

5.1.4.15 Real-time Clock

A real-time clock is provided within ASIC to give the time and date. The alarm

function can also be programmed to the ALARM pin. This will initiate the

processor regulator and thus also the radio although it is in OFF state.

The ASIC circuit has a continuous power supply and the 32 kHz clock crystal

runs constantly. Not even the RESET line stops the clock. If the power supply

has dropped too low, the clock will need to be reset with the radio buttons (from

the menu).

5.1.4.16 Answer Module

Answer module can save a maximum 16 second message. The message can

be recorded from the microphone, external microphone or RX-audio. The

message can be sent to the earphone, external earphone or TX-audio.

5.1.5 Function Description

OA0700 Audio

The audio module is comprised of the following functions:

1. TX-audio signal handling

2. RX-audio signal handling

3. Fii signal handling

4. FFSK modem

5. DTMF generator/receiver

6. Signal level detectors

7. Compander

8. Expander

9. Buzzer

The audio functions are mainly located in a single circuit AK2339. This chip

from AKM is controlled by a serialbus. It is possible to shut down parts of the

circuit, one block at a time to minimise power consumption.

5.1.6 TX-audio

The input from the microphone is fed to the audio circuit I405 pin 61, which is

an operational amplifier (AMP1) inverting input. The operational amplifier gain

is set by resistors R413 and R416. The amplifier is connected as a low pass

filter. After the amplifier is the microphone switch and then summing junction of

MIC input signal, EXTMIC input signal and transmit DTMF signal. VR1 is a

programmable amplifier, which sets the microphone signal (sensitivity) to the

correct level. After VR1 comes band-pass filter for transmitting the voice signal.

After the TXBPF is the summing junction (AMP6) of the tx signal and transmit

answer signal (ANAOUT). TXDET is the transmit voice signal detection circuit

which works as a full wave rectifier. Next comes ATT1 which is an attenuate

circuit to set the transmit signal level in the HF-mode. COMP is the compressor

circuit. Compress the transmitting signal amplitude with square root law. It can

be hypassed. The linearity is adjustable by the control register CVR. Next is

VR2, normal deviation gain control circuit to set the signal level. The P/E &

LIMIT pre-emphasis circuit and limiting circuit, emphasize the higher frequency

component of the signal in order to improve the signal-to-noise ratio of

modulated signal. This block includes a limiting circuit for signal amplitude in

order to confine the maximum deviation of the transmit modulated signal.

TXLPF is the low pass filter to reject the higher frequency component on the

transmit signal. VR3 is a maximum deviation gain control circuit to set the

transmit signal level. After the VR3 comes switch TXAUDON, which mutes the

tx-audio signal using the TXMUTE control. From the switch, the signal is fed to

the summing junction (ADD3) of the tx-audio signal, FFSK signal and Fii-

signal. Next comes VR4 gain control circuit to set. SMF1 is smoothing filter for

tx-audio signal. The tx-audio signal is then fed to the V102 connector pin 20.

5.1.7 RX-Audio

The rx-audio signal coming from the receiver through the V102 pin 8 is fed to

the audio circuit I405 pin 23. Inside the circuit, the signal is fed to the

operational amplifier (AMP2) inverting input. The amplifier gain is set by

resistors R440 and R441. The signal is next passed through an anti-aliasign

filter. VR5 is a gain control circuit to set the rx-audio signal to the correct level.

Next comes de-emphasis (D/E) circuit. Equalize the pre-empassized rx-audio

signal. The signal passes from the D/E through the switch RXAUDON. RXBPF

is the band-pass filter for the rx-audio signal. RXDET is the rx-audio signal

detection circuit. This circuit works as a full wave rectifier. After the RXBPF

comes expander circuit (EXP). Expand the rx-audio signal amplitude. It can be

bypassed. The linearity is adjustable by the control register EVR. VR6 is a gain

control circuit to set the rx-audio signal to the correct level. After VR6 comes

the RXMUTE switch, which is operated by the RXMUTE control. ADD4 is the

summing junction of the rx-audio signal, external signal (not used), DTMF

signal and transmit signal. VR10 is the volume control circuit to set the level of

earphone and external earphones. The rx-audio signal is connected through

the receiver driver (RECAMP) to the earphone.

5.1.8 FII Signal

The NMT system uses the FII signal to check the radio path quality. This

approx. 4kHz signal is split from the rx-audio signal after the VR5 and is filtered

through the band-pass filter (FBPF). VR7 sets the FII signal to the correct level.

Switch FILOOPON can be operated by the FIION control, to be summed with

the tx-audio signal before the VR4.

5.1.9 FFSK Modem

The FFSK data signal from FFSK modulator to be transmitted is passed

through the FFSK low-pass filter and pre-emphasis (FFSKP-EM) to the VR9,

which adjusts its level. The data signal is switched using switch FFSKTXON.

The data signal is summed with the tx-audio signal by the ADD3.

The received data signal is split from the rx-audio signal after the de-emphasis

circuit. The data signal is fed through the FFSK band-pass filter to the FFSK

demodulator and FFSK data detector.

FFSK DET block. The block works to judge the FFSK signal existence by

comparing the amplitude of the noise reduced FFSK signal and the provided

detection level standard. Once the detector judges a valid FFSK signal, ’H’

signal is put out on the FFSKDET pin (pin43). The data detector speed is

determined by the external condensator C438.

FFSK DEMOD. To recover 1200bps receive data and clock from the FFSK

signal fed on DEM1 pin.

The modem is connected to the CPU by series lines, the receiver to a

synchronised gate, and transmission is directed to an ASIC series output. The

modem provides a 1200 Hz clock signal RXCLK to the processor and TXCLK

to ASIC.

5.1.10 The DTMF Generator/Receiver

The DTMF generator provides all sixteen standard DTMF tones, and each

individual frequency separately. The generator is used to produce both key and

alarm tones and enable numeric message transmission during a call.

Key and alarm tones are taken from the generator to switch DTMFRXON and

is summed with the rx-audio signal. Key tones are connected to earphone and

external earphones.

When transmitting a numeric message, the DTMF tones produced by the

generator are fed through the VR8, which set the DTMF signal level to the

switch DTMFTXON, and then the signal is summed with the tx-audio signal.

The DTMF receiver takes in numeric messages sent to the phone. The route to

the DTMF receiver splits from the rx-audio signal after the summing junction

ADD4.

5.1.11 Signal level detectors

Audio signal level detectors are required for the HF-function to measure the

transmitted and received audio signal level, and to study the data signal level.

Measurement is done by rectifying the signal, and the resultant DC voltage is

read by a phone’s prosessor A/D converter. TXDET is at the transmission side

detector and RXDET is at the receiver side detector.

5.1.12 Compander/Expander

Compander and expander units are included in audio asic I405 and can be

controlled by registers.

5.1.13 Alarm buzzer

Tones for the internal alarm tones are provided by the DTMF generator. The

internal alarm tones path way is DTMF generator, VR8, switch DTMFRXON,

summing junction ADD4, VR11, AMP5 and buzzer. The buzzer volume is

controlled by the DA3.

5.3 RF MODULE

5.3.1 General

The RX synthesizer generates an upper side injection frequency for the receiver.

The injection frequency is fed to the receiver’s first mixer.

Operating voltage

4.75VDC

Current consumption

Output level to the receiver

Frequency range

14 mA

+1 dBm

540,25...544,725 MHz

5.3.2 Functional Description

The RX injection frequency is generated with a phase locked loop. The VCO pro-

duces the injection frequency determined by the control voltage. After the VCO

stage comes the amplifier stage Q320. After the amplifier stage, part of the signal is

fed to the synthesizer circuits I300 divider. The synthesizer circuit contains a pre-

scaler, programmable divider, reference frequency divider, and a phase detector.

The synthesizer circuit produces current pulses at output DO1 as controlled by the

phase detector. The current pulses either charge or discharge the loop filter. The

VCO control voltage is derived from the loop filter output.

The synthesizer 12.5 kHz reference frequency is made by dividing the 12.8 MHz sig-

nal from the temperature compensated oscillator (TCXO). The series-form signal

which controls the channel frequency comes from the audio/processor-module via

connector V600. SDATA, SCLK and SLE signals are common to both TX- and RX-

synthesizers. A positive pulse in the SLE line loads the division ratio (corresponding

to the frequency of the channel) fed to the SDATA line, to the synthesizer circuit

I300.

Frequency range

+6 dBm

453.000...457.475 MHz

5.3.5 Function Description

The TX frequency is generated with a phase locked loop (PLL). The VCO produces

the injection frequency determined by the control voltage, and the VCO also has a

modulation input. After the VCO stage come two amplifier stages Q420 and Q430.

These ensure separation between the VCO and transmitter, and also boost the

injection level sufficiently. Part of the signal is fed from between the amplifier stages

to the synthesizer circuit I300 pre-scaler input Fin2. The synthesizer circuit contains

a pre-scaler, programmable divider, reference frequency divider, and a phase detec-

tor.

The synthesizer circuit produces current pulses at output DO2 as a result of the

phase detection. The current pulses either charge or discharge the loop filter con-

densators. The VCO control voltage is derived from the loop filter output.

The synthesizer 12.5 kHz reference frequency is made by dividing the 12,8 MHz sig-

nal from the temperature compensated oscillator (TCXO). The series-form signal

which controls the channel frequency comes from the audio/processor-modules via

the V600 connector. SDATA and SCLK signals are common to both TX- and RX-

synthesizers. A positive pulse in the SLE-line loads the division ratio (corresponding

to the TX frequency of the channel) fed to the SDATA line, to the synthesizer circuit

I300.

Modulation is fed to the TX synthesizer TX-AUDIO line. The frequency response is

corrected by the components R463 - R465, C461 and C462. Modulation sensitivity

is set by the resistor R460.

When the RF signal isreceived it is brought through the duplex filter to the amplifier

stage Q101. The amplified signal is passed through the attenuator to the double-bal-

anced mixer X 102.

The upper side injection frequency is brought from the synthesizer through a small

resistive attenuator to the mixer LO pin 1 (LO = local oscillator). The 77.25 MHz

intermediate frequency from the mixer output is fed through the IF-SAW filter X102

to the FM IF-circuit I201.

RX injection frequency 540,250...544,725MHz

Injection-level/impedance +1 dBm / 50 ohm

The second intermediate-freqency local-oscillator-frequency required by the FM IF-

circuit is generated by multiplying the 12.8 MHz reference-oscillator frequency by

six. The multiplier circuit is made with transistor Q201.

The second intermediate frequency is 450 kHz. The phase-shift required by the

quadrature detector is made with the parallel-circuit L203 and C226. The detected

AF-signal temperature correction is done in the buffer amplifier stage.

5.3.10 Function Description

The transmitter unit is comprised of three amplifier stages and two attenuator

stages. The pre-amplifier Q600 and power module I620 form the transmitter ampli-

fier chain. The attenuators surrounding the pre-amplifier are included to enhance the

electric separation between the TX synthesizer and the transmitter. C650 enhances

power module efficiency.

The operational amplifier I610 and transistors Q610 and Q611 serve as a power reg-

ulator circuit, which adjusts the power level so that the voltage from the transmitter

power detector (D610) and the control voltage TXPWR from the audio/processor

unit are equal. The power-module power-control voltage must not exceed 4V.

I601 serves as voltage regulator for the power controller and also as the ON/OFF

switch for RF output power.

When the phone is connected to an external voltage supply, the audio/processor unit

raises the transmitter power by approx 1.0 dB using the TXPWR control.

7.1.2.6 Operation

Operating voltage is fed to pin EXTVB/6. L100/C104 filters the power supply and

D100 limits any voltage peaks. When the radio telephone is placed in its handset, a

voltage is fed through the BOX/3 pin which triggers Q201 and Q200 open.

The regulator I200 feeds +9V to the audio stage and PC-connector pin 3 and I210

feeds +5V to other functions. External relay drivers Q231 and Q241 are controlled

by I2C I/O-expander I220.

The HF microphone gets its bias voltage through resistors R330 and R331. I330

serves as the microphone amplifier and as a low-pass filter with a border frequency

of 3.3 kHz.

The analog switch I320 connects the HF microphone or HS microphone signal to the

EXTMIC-line.

The analog switch I322, controlled by AUX_MODE selects either microphone (HS or

HF) or external signal source AUX_MIC to be connected to EXTMIC signal pin.

The analog switch I430 connects audio signal to handset earphone or HF-speaker.

The analog switch I431 connects audio signal to connector PC/AUX/8 or to HS erp /

HF spkr.

When audio power amplifiers I410 and I460 are not in use, they are in mute-mode.

7.2.2.6 Operation

Operating voltage is fed to pin EXTVB/6. L100/C104 filters the power supply and

D100 limits any voltage peaks. When the radio telephone is placed in its handset, a

voltage is fed through the BOX/3 pin which triggers Q201 and Q200 open.

The regulator I200 feeds +9V to the audio stage and PC-connector pin 3 and I210

feeds +5V to other functions. External relay drivers Q231 and Q241 are controlled

by I2C I/O-expander I220.

The HF microphone gets its bias voltage through resistors R330 and R331. I330

serves as the microphone amplifier and as a low-pass filter with a border frequency

of 3.3 kHz.

The analog switch I320 connects the HF microphone or HS microphone signal to the

EXTMIC-line.

The analog switch I322, controlled by AUX_MODE selects either microphone (HS or

HF) or external signal source AUX_MIC to be connected to EXTMIC signal pin.

The analog switch I430 connects audio signal to handset earphone or HF-speaker.

The analog switch I431 connects audio signal to connector PC/AUX/8 or to HS erp /

HF spkr.

When audio power amplifiers I410 and I460 are not in use, they are in mute-mode.

8.1.3 Operation

8.1.3.1 General

Power supply unit is connected to one of the connectors on the back of the unit.

Connections on these two connectors are identical to each other. Supply voltage

(VB) turns on regulator I124 which is used to generate +5 VDC supply (VCC) for pro-

cessor and other electronics. Note that the power amplifiers of the earphone signal,

I499 and I528 do not use VCC but VB instead. Once the VCC signal has risen, also

signal CADET is activated. This causes the phone to communicate with the I2C cir-

cuit and register that office kit is present.

8.1.3.2 Processor / charging

The processor I264 is National Semiconductor COPCF888. Crystal frequency used

is 8,00 MHz.

I/O pins/signals are as follows:

PWM_CHK (not used)

A/D input I3 is used to measure the voltage of the spare battery. Amplifier I277 con-

verts the input voltage level into the new range which is suitable for A/D input. Out-

put G3 is a PWM signal which is converted with R291 and C293 into analog DC

signal. This signal is used to control the output current of the power supply unit. Out-

puts D0 and D1 are used to turn on charging current for the phone and spare bat-

tery. P-channel fets Q211 and Q221 are normally in non-conducting state (gate

voltage tied to VB) and are turned on with fets Q212 and Q222 as the control signal

has been activated. In normal operation fets Q211 and Q221 are never simulta-

neously in the conducting state.

Product: DDS-50(Office set) / YO0311

27.1.1999

Spare battery discharge is controlled with signal D2. High level on output switches

transistors Q287 and Q285 into conducting state, which makes current flow through

resistors R280-283 and transistor Q285. Nominal value of discharge current is ~ 180

mA.

Signal D3 is used to turn on/off the detect current supply I234. The logic high signal

turns the regulator off and logic low on. When the phone is present, the state of this

pin is usually low. Only when the charge control line I0 has a value greater than 4

VDC does it have a high output. Regulator I234 output is ~ 7 VDC, Imax 150 mA.

Charge indicator leds are turned on using the signals D4 to D7. Logic high signals

switch transistors Q303, Q305, Q313 and Q315 into conducting state. The emitter

pins of the transistors are directly connected to the anode pins of the leds.

The signal P1 (HF_OFF) of the I2C circuit I203 is used to control the analog

switches I435 and I437. Q512 inverts this signal for switch I484. The inverted signal

is also used for controlling the MUTE pin of the power amplifier I528. Low level sig-

nal turns MUTE on and high level signal (3 V) off respectively. Switch I481 and

MUTE pin of the power amplifier I499 are controlled with signal HS_CTRL. This sig-

nal is inverted from the DC level of the handset earphone signal.

The HOOK signal is controlled with the handset. Whenever the handset has been

placed on the holder, the DC level of the HS_ERP signal should be ~ 4,2 V. Remov-

ing the handset from the holder makes the voltage drop to a value of 0,4 VDC. This

signal and the transistors Q474 and Q475 are used to control the DC level of the

EXTERP signal. ON_HOOK level is ~ 5 VDC, OFF_HOOK ~ 0,6 VDC.

9.1 LINE INTERFACE LIF-40

YO0245

9.1.1 General

The line interface is an accessory for a Benefon phone to enable a tele-device

approved for the general network to be connected to the handportable. The tele-

device should be approved for connection to a fixed line network.

9.1.1.1 Telefax devices and modems

An error correcting modem (e.g. MNP, LAPM), and telefax (Level III or newer) are

recommended for data transfer. Check that the recipient also uses an equivalent

protocol, otherwise the error correction feature will not operate.

The data transfer speed will depend on the quality of the call. Whenever possible,

use a fixed baud rate. An automatic baud rate selector does not necessarily work

with a cellular phone.

The modem/telefax may suffer interference from a powerful radio field. Check this by

testing with e.g. a magnetic antenna.

9.1.1.2 Fixed line telephones

Check that the telephone does not suffer interference from the handportable radio

field. Connect the line interface to the desired tele-device. Make a call from the

device and move the hand-phone antennna around the vicinity of the device.

9.1.1.3 Cordless telephones

These are not recommended for use with the line interface.

9.1.1.4 Other tele-devices

Before connecting the device to the line interface, make sure that the device has

been type-approved and meets the standards required for connection to a fixed line

network.

9.1.2 Using the line interface

9.1.2.1 Calling from the tele-device

When the dialling tone is heard through the tele-device handset, dial the area code

and number (max.23digits). The number dialled will appear in the handportable dis-

play.

About 7 s. after the last entry, the hand-phone will initiate the call. If the call is unsuc-

cessful, a busy tone will be heard from the handset.

Product: LIF-40 (Line Interface) /

27.1.1999

YO0245

When the dialling tone is heard, there is approx. 30 s. time to start dialling the num-

ber.

The number may also be dialled from the handportable keyboard.

9.1.2.2 Answering a call with the tele-device.

A call is answered normally by lifting the tele-device handset or allowing the device

to answer automatically.

If the call has been answered by the handportable , it can be transferred to the tele-

device as follows: Lift the tele-device handset (or press ON LINE from the telefax),

and press the handportable HF key.

9.1.2.3 Terminating a call.

The call is terminated normally by returning the handset to its cradle.

The call may also be terminated by pressing the lightning key on the handportable.

The busy signal will then be heard from the tele-device handset. Do not forget to

replace the tele-device handset, as the line interface uses power from the handport-

able battery.

9.1.2.4 Making and receiving a call with the hand-phone

A call can be made and received normally from the handportable as long as the tele-

device handset has not been lifted.

9.1.3 Technical information

The line interface only consumes power when the tele-device handset is lifted.

The phone battery can be charged and the line interface used simultaneously by

connecting the charger and line interface to the handportable through a branching

unit.

9.1.3.1 TROUBLE SHOOTING

When moving about or in an area with poor reception, radio fade and changes

between base stations will interrupt radio contact. Typical symptoms of data transfer

errors are random characters, missing characters, loss of contact, drop in data trans-

fer speed, missing lines and error lines in telefaxes.

The data transfer device and program should withstand momentary breaks.

An error correcting modem is only of value if it is available at both ends of the trans-

mission.

It is recommended to stay in one place during data transfer, and to select a location

with as strong field strength as possible.

The line interface takes its power from the hand-phone battery, so allow for the

increased consumption by first charging the battery or by connecting the charger

using the branching unit.

Use the cellular phone exchange data transfer service to eliminate problems caused

by channel changing.

Modem settings:

- long elapsed time range for carrier wave control (ATS10=30)

- short data blocks (AT&BS0)

- error correction ON (AT&E2)

- speed select (AT$MB2400)

There are tele-devices that take their power from the telephone line, in which case

the line interface supply of 25 mA will not be enough. These, generally non-

approved devices are not recommended for use with the line interface.

Typically, problems arise from modem or telefax internal settings (see tele-device

operating manual). Data transfer may function normally with a fixed telephone line,

but not with the handportable. Frequently the settings for radio transmission have to

be found by experimentation.

9.1.3.2 Functional Description

You can use the line converter for connecting your Benefon handportable to any

two-wire data terminal approved for use in the public telephone network. The line

converter receives its operation power from the handportable battery; a separate

branching unit enables a charging device to be simultaneously connected to the

handportable. The line converter consists of the following operations: ring voltage

and line current generation, audio input and output, line current detection (HOOK),

and low-power standby mode.

The line converter can be divided into seven different functional units: audio, fre-

quency divider, chopper, current sink, I2C connection, free/reserved tone genera-

tion, line switches for ring signal, and HOOK detection.

9.1.3.4 Audio

The audio unit consists of operation amplifiers I100C and I100D and their peripheral

components. The low-frequency alternating current passing through the two-wire

data terminal is formed by a current coming from the I100D output through resistor

R109 (signal received by the data terminal) and by a current coming through resistor

R109 to I100C (signal transmitted by the data terminal). R109/C111 is used for gen-

erating the line impedance appropriate to the data terminal.

The -3 dBm level (549 mVrms / 600 ohm) causes a 400 mVrms voltage in the EXT-

MIC line and a ±3 kHz deviation in the transmitter. Likewise, the ±3 kHz deviation in

the receiver causes a 400 mVrms voltage in the EXTERP line and a -16 dBm level

(123 mVrms / 600 ohm) in the data terminal.

9.1.3.5 Basic Frequencies

Components R114, R115, C109 and I105 form an oscillator vibrating at a frequency

of approx 220 kHz. This frequency is divided within I105 into frequencies 430 Hz

(free/reserved tone) and 26 Hz (ring frequency).

9.1.3.6 Switched Mode Voltage Converter

The basic chopper connection consists of operation amplifier I100A, quad NAND

I101, MOSFET Q100, and coil L100. Saw wave to the I101A input pin 2 is generated

from the basic frequency 220 kHz by using resistor R131 and capacitor C121. By

changing the dc-level of the saw wave, the operation amplifier I100A controls the

pulse width at gate Q100.

An extended width pulse from the basic frequency is brought to the I101A input pin 1

in order to make sure that the MOSFET is led to be momentarily non-conductive in

every cycle.

YO0245

While Q100 is conducting, the energy flows through resistor R108 to the coil L100.

When the switch Q100 stops conducting, the energy received by L100 is discharged

through the rectifier diode D100 to the capacitor C106. The fet is protected by C122

and C123 against excessive voltage peaks, while L101/C107 functions as a low-

pass filter for filtering the ripple voltage. The output voltage in capacitor C107 pins

depends on the RINGON signal mode, being approx 50V in the ring mode (RIN-

GON=1) and 15 ±3 VDC in the normal mode (RINGON=0).

9.1.3.7 Current Sink

The current passing through the two-wire data terminal is kept constant by a con-

stant-current load formed by I103A, Q101 and Q102. The closed-loop current is 25

±5 mA.

9.1.3.8 Connection of I2C

The control connection is made with the I2C circuit I104, which controls the switch-

ing-on of the voltage, call and free/reserved tone according to the commands com-

ing from the portable. Data received by the portable is a HOOK mode, the change of

which is identified by the portable as interruption.

In addition, one of the I104 inputs (pin 7) has been connected to the ground so that

the portable receives interruption every time the voltage is switched on.

9.1.3.9 Free/Reserved Tone

The free/reserved tone is connected by transistor Q106 to a filter consisting of the

operation amplifier I100B. In this filter, the tone is reduced to a suitable level, and the

square wave received from Q106 is made more gentle.

9.1.3.10 Line Switches

The double fet switches Q107/Q110 and Q109/Q108 form the line switches which

switch on the ring voltage to the two-wire connection. While conducting, Q104

switches the double fet Q107/Q110 to conduct, whereby the current passes in line

connection from pin LB to pin LA. While conducting, Q103 switches the double fet

Q109/Q108 to conduct, whereby the current passes in line connection from pin LA to

pin LB.

Q111 ensures that only one of the switches Q103 and Q104 is conducting and that

R144/R145 form the voltage distribution which will prevent the VDD from overflowing

through VCC 1102 in standby mode.

9.1.3.11 HOOK Detection

HOOK detection is carried out by operation amplifier I103B which controls the data

terminal current coming from resistors R123/R124. The threshold level is changed

according to the power mode in order to detect the OFF-HOOK mode using a low

battery voltage and to make sure the OFF-HOOK mode is not switched on too easily

during a call.

9.2.3 Operation

Audio routes for either an external handset or a line converter are selected

using audio switches I201 (mic) and I202 (erp). The operation is controlled by

the HOOK data coming from the XHSERP line. OFF HOOK audio signals have

been routed to connector HS, and ON HOOK audio signals to connector PC.

Voltage regulation is done by components R205, C207 and D201.
