Installation Instructions

PROLOGUE
These installation instructions have been prepared to assist fitters in installing the
equipment, and are as such only to serve as a guide. Nothing beats common sense
and good experience.
Installation is always based on the need of the customer to use the phone in the
environment in which it will be installed. Negotiate with the customer where the different parts will be installed. It is important that the customer tells of his own preferences and choices, and that the fitter/salesman tells where it is possible/advisable to
locate different items.
It is the salesman’s responsibility to see that the installation order is properly filled
out.

RECOMMEND
- antenna location on the roof
- handset location does not interfere with road safety
- speaker located in the driver’s side leg-room
- microphone as close as possible to the driver’s mouth
- car radio muting

ASK IF THE USER WANTS
- automatic start-up
- additional alarm
- car radio muting

with the connecting cable.

2.0.6 Microphone Installation
The following points should be noted when installing the microphone:
- the microphone must not be directed at the speaker
- it is not recommended to mount the microphone on a sun-blind, because the
microphone direction will change with movement of the sun-blind
- the microphone must not be in the driver’s line of vision, where it could be
distracting

Installation Instructions

28.1.1999

- maximum range from driver’s mouth - about 20 cm
- the microphone is connected to the handset with a jack-plug
- it is not recommended to mount the speaker on a door-pillar or similar location
due to the high background noise at the side of vehicle

2.0.7 Voice-Controlled HF Installation
To ensure trouble-free HF operation, be sure to mount the speaker and microphone
carefully, as descriped on the previous page.

2.0.7.1 HF Tuning
With installation complete, connect loccal-box to both the handset spiral cable
and the handset system cable, and set telephone to local mode; press 1# and
start the vehicle; check the reading on the display for different revs, and press
OK twice when it is at its greatest.
Best results are obtained when HF tuning can be accomplished with the
vehicle moving at normal speeds.
Default value on display is 34, and the final value is 34 + compensation value.
In practice 40...55, depending on the vehicle.

2.0.8 Mounting the Cables
There are two cables coming from the radio module: power and system cable.
The red supply cable connected to the battery.
With a 24 V supply, a voltage regulator must be used.
The black ground cable should be connected to a sufficiently firm place near the
radio module.

4.0 LOCAL SERVICE COMMANDS
4.0.1 General
There is a special program module called LOCAL which makes it possible to set,
read and program various features of the phone.
In order to activate the LOCAL program it is necessary to connect a local box
between the radio unit and the handset. When the power is switched on, and the
local box is connected, the LOCAL program becomes activated.
There are two kinds of local boxes. One merely has "service rights", i.e. you cannot
program subscriber number. The other has "full rights", i.e. there are no restrictions
in LOCAL.

4.0.6 Local-Box
4.0.6.1 General
LOCAL = operating mode where it‘ s possible to give commands to set, read and
program the MS features.
To get the MS to LOCAL a local-boxes, one merely has "service rights" i.e. you cannot program subscriber number. The other has "full rights", i.e. there are no restictions in LOCAL.
Each box has it‘ s own serial number. Serial number and programming rights are
installed by manufacturer. Serial number is used for identifying the subscriber number programmer and it is stored automatically to MS during programming.
There is text LOCAL on the display when the local box is connected and power is
switched on.

4.0.6.2 Features Of Local-box

- Set NORMAL/SERVICE switch NORMAL position
To be measured from audio of the radio unit:
- Set NORMAL/SERVICE switch SERVICE position and RADIO/HANDSET

OT0001 Transmitter

28.1.1999

6.0 TRANSMITTER MODULE OT0001
SPECIFICATIONS:
OT0001 Transmitter

Operating voltage 10.8...15.6 VDC
Current consumption max 4.5 A
Input power level 10 dBm (+2/-2 dB)
Output power level max 44 dBm (25 W) without a duplex filter
Frequency range 453.000...457.475 MHz

6.0.1 Connector Description:
4-pole connector:
pin 1, voltage from directional coupler max 10 V
pin 2, control voltage for RF-power max 8 V
pin 3, bias for the preamplifiers 8 V
pin 4, GND

6.0.1.1 Transmitter operation:
The transmitter is a 5-stage amplifier chain. The two preamplifiers (Q600/601) operate in class AB as linear amplifiers. The final amplifier (I600) is a class C power module. The output power is controlled with a loop: A signal coming from the directional
coupler is rectified and filtered. Then it is fed through processor controlled voltage
attenuator to the integrator, which has a preset reference voltage (a corresponding
value for 15 W output power). The control voltage from the integrator is amplified in
DC-amplifier (Q610/611) and fed to the preamplifiers/the first stage of the power
module. RF-power input has a 6 dB attenuator to improve impedance matching
between synthesizer and transmitter in different power level conditions.

6.0.2 Tuning Instructions:
Tuning can be done in local mode or using CMT-tester.
Set a power supply to 15.6 V.
Input signal 10 dBm (10 mW) on channel 090 from the synthesizer or signal generator.
Connect a 50 ohm dummy load and a power meter to the antenna connector.
Transmitter on (33#).
Tune output power with trimmer R162 on OA0014 (audio/processor) -module to
41.8 dBm (15 W).

484.400...488.875 MHz +10 dBm/50 ohm.

The receiver RF-signal is brought through the duplex filter NBF40001 to the amplifier
stage Q701. The amplifier signal is led the dual balanced mixer X701 through the
band filter L703.
The upper injection frequency is brought from the synthesizer unit to the LO input of
the mixer through a small resistance attenuator. The IF (intermediate frequency)
21.4 MHz gained in this way is amplified and led through crystal filters X702 and
X703 to the FM IF-system IC-circuit (SA605D). The circuit includes another local
oscillator, and another mixer.
The second IF is 455 kHz: there is first a 6-pole ceramic filter, and another 4-pole filter in the limiter amplifier chain.
The temperature compensation for the AF-signal indicated has been included in the
buffer amplifier stage I702/B.

OR0002 Receiver

28.1.1999

The temperature compensation for the RSSI signal has been made with the diode
pai D701, which is followed by the buffer amplifier I702/A.
The receiver unit gets +9 V regulated operating voltage from the current input unit
OW0001 through the audio/processor unit.
The operating voltage is dropped with the transistor Q703 to the lower required by
the IF circuit.

7.1 Receiver OR0002 settings
7.1.1 Supply Voltages
A regulated +9 V power supply is fed to the module via connector V701 pin 1.
The intermediate frequency module uses a ca. +6 V supply which can be checked at
the solder joint of condenser C727 located on top of the board.

7.1.2 Setting Order:
1. Detector coil V707
2. Crystal filter matching coils L705, L706
3. Helical bandpass filter
1. Adjustment of detector coil L707 is not dependant on the channel used.
Feed a -13 dBm RF-signal to the aerial connector.
Enable RX audio (local 22#).
Connect the local box meter connector to an oscilloscope or AC voltmeter (1 V
range).
Adjust coil L707 to maximum value.
NOTE:
(Changing the receiver may cause difference at audio levels. When changing the
module, the audio unit RX adjustment should also be checked. If the RX adjustment
has been changed, then the FII-deviation must also be checked.)
2. Adjustment of the crystal filter matching coils L705 and L706 is not dependant on
the channel used.
Feed a -13 dBm modulated RF-signal to the aerial connector.
Enable RX audio (local 22#).
Connect the local box meter connector to a SINAD meter.
Trim coils L705 and L706 for maximum value on the SINAD meter and repeat
the adjustment (35...50 dB SINAD psoph.).

The effect of these coils can be seen even more clearly if the SINAD meter is connected direct to the RX audio output connector V701 pin 3. This simplifies their
adjustment.
3. Helical bandpass filter
This adjustment influnces spurious response rejection and tuning must be done
carefully using suitable plastic screwdriver, which does not disturb tuning.
Switch on the first channel (local 35#)
Feed to the antenna connector RF-signal at level -93 dBm (463.000 MHz)
Connect DC-voltmeter (analog display) 3 V max connector V701 pin 2 RSSI
Adjust voltmeter to maximum with helix core nearest to the duplexfilter
Change receiver on the highest channel (local 37#) (467.475 MHz)
Adjust voltmeter to maximum value with the other core of the helix

8.0 SYNTHESIZER MODULE OS0021
SPECIFICATIONS
OS0021 Synthesizer

8.0.1 Functions
This unit generates the high frequency signals for respective channel frequencies:
this gives a modulated channel-frequency signal for the transmitter unit and upper
band injection frequency for the receiver unit.
The synthesizer is connected via connector V401 to the processor/audio unit.

8.0.2 Circuit Description
The module can be divided into three main units: TX-synthesizer, RX-synthesizer,
and common power supply unit for both synthesizers.
The power supply unit provides stabilized voltages +9 V (TP1) for the high-frequency
parts and +5 V (TP2) for the synthesizer and pre-scaler circuits and TCXO. The
active components Q401...Q405 are included in the power supply unit.

8.0.3 RX-Synthesizer
Receiver injection frequency is generated by a phase-locked loop (PLL). The coil of
the voltage-controlled oscillator is a strip line on the PCB. VCO center frequency is
adjusted with trimmer C436. Q411 is the oscillator transistor. Next, there are two
amplifier stages Q412 and Q413. The circuit is provided with a 3 dB atttenuator for
the outcoming signal, with a part of this signal being fed to the pre-scaler I4022. This
is called the dual modulus divider having scaling factors 128/129. The divided frequency is fed to the synthesizer circuit I401.

OS0021 Synthesizer

The synthesizer circuit I401 gets its control signals from the processor unit via connector V401 in serial form. Signal CLK is the clock-frequency for synchronising the
transmission of channel-frequency data to the synthesizer. The scaler information is
stored by a latch-pulse on SRE bus sent to the synthesizeer circuit.
The divided frequency is compared to the reference frequency with a phase comparator. The exact reference frequency comes from the thermal-compensated crystal
CXO). This 12.8 MHz frequency is divided by a factor of 512 in the synthesizer circuit, giving the reference frequency of 25 kHz (= channel space).
The synthesizer is phase-locked when these two frequncies fed to the phase comparator are equal. The phase comparator emits positive pulses in response to low
VCO frequency, and ground pulses for high VCO frequency. The phase comparator
output chargers and dischargers the capacitor C417 through the resistor R422, while
R423 and paralled-connected capacitors C418/419 stabilizing the loop function.
The voltage fed to the above described capacitor is amplified with transistors Q408/
409. Two RC-loops R427/C422 and R428/C433 prevent the pulse transfer from the
phase comparator to the VCO. The filtered DC voltage alers, when needed, the
reversed voltage of the capacitance-diode D403 located in the oscillator circuit, i.e.
controls the VCO frequency (TP6).

8.0.4 TX-Synthesizer
TX-frequency is generated with a similar phase-locked loop to the above described
Rs-injection frequency.
There are after the VCO three buffer amplifiers Q416, Q417, and Q418. The divider
and synthesizer circuits function like the RX-synthesizer. There are common DATA
and CLK signals. The scaler information is stored by a latch-pulse on STE bus sent
to the synthesizer circuit I403.
TX-synthesizer uses the phase comparator outputs φ/R and φ/V . This is followed by
avtive low-pass filter for control filtering. The VCO control voltage range is widened
by raising the filter IC power supply with a voltage converter Q414 (TP7). This filtered control voltage is fed to the capacitance-diode-cathode in the oscillator circuit.
An excessive VCO frequency prompts φ /V output-pulses from the phase comparator, but the φ /R output will stay in "1"-state. Too low VCO frequency prompts in turn
negative O/R output-pulses from the phase comparator, while the O/V output stays
in "1"-state.
Modulation is taken from the connector V401 pin 2 (TP5) via level control R459 to
the capacitancediode anode of the VCO circuit. With this arrangement the loop filter
does not affect the modulation by attenuating the high frequencies.
With low modulation frequencies (300...500 Hz), linear AF-response is maintained
by feeding the loop with a "compensation modulation" through the integrator I405.
Compensation is adjusted with trimmer R457 so that the AF-response is linear at
300 Hz frequency.

Operating voltages require no adjustment.
+ 9 V accuracy is affected by the Zerner diode V401 (5V6).
Accuracy of this diode is 5% in 0-series. It will be changed to 2% diode. The resistors R408, R409 used for voltage settings have 1% tolerance.
The + 5 V voltage reference is also taken from this 5V6 diode.

8.1.2 RX-VCO Adjustment
Change to lowest channel (local 35#)
Measure voltage TP6, adjust voltage RX-VCO to 3 V with trimmer C436.

Change to highest channel (local 37#)
Check that adjustment voltage is now approx 6 V.
(Synthesizer functions are optimized with above VCO settings-accuracy, channel
delay, overlap, channel selectivity).
(VCO-accuracy = voltage difference between end channels)

8.1.3 TX-VCO Adjustment
Switch on TX VCO (local 34#) or transmitter (local 32#)
Change lowest channel (local 35#)
Measure TP4 voltag, and adjust TX-VCO voltage to 5 V with trimmer C498.
Change to highest channel (local 37#)
Check that operating voltage is now approx 7.5...8 V.

The operating voltage range has been raised to 13V. It may be necessary to deviate
from the above settings in some production runs in order to ensure linear modulation
for end channels.In practice the operating voltage can be between 3V...10V.

8.1.4 Setting Channel Frequency:
8.1.4.1 Measuring Devices:
Frequency counter (resolution 10 Hz)
Switch TX on (local 32#)
Switch to lowest channel (local 35#)
Set correct channel frequency MHz with TCXO trimmer (+/-100 Hz)

8.1.5 Adjusting The Modulation:
Adjust the modulation along wIth the audio unit; see setting instructions for the audio
unit, TX-AUDIO.
Set to middle channel (local 36#)
Switch TX on (local 32#) e.g. medium power.
Feed "normal" modulation to microphone input (f mod. 1 kHz 1 Vrms)
Switch microphone off (local 29*)
Switch TX-audio on (local 21#)
Check that TP5 voltage is now 550 mV rms.
Adjust deviation to +/-3 kHz peak with MOD-trimmer R459.
Check deviation of end channels, difference max +/-150 Hz or +/-0.5 dB

8.1.6 Correcting The Low-frequency Response:
Drop mic input level until deviation is +/-1 kHz.
Measure TP5 voltage (reference level).
Change modulation frequency to 300 Hz.
Raise mic input level until TP5 voltage increases to the same level as the reference
level.
Adjust deviation to +/-1 kHz with COMP-trimmer R457.

SUPPLY VOLTAGE FOR TRANSMITTER

9.0.4 Operation Principles:
Noise from vehicle electrical-system is filtered with low-pass filter C810, C811, L810,
C813, C812, L811, and zenerdiode D812. Main relay A800 in driven from connector
X820/4(5 V). The speaker must be connected to X800/5, or otherwise transistor
Q813 conducts and cannot swich the power ON. D811, D814, and transistor Q810
prevent switching power ON when supply voltage is too high.
The output voltage of the regulator is set by R806, R807, and zenerdiode D800, and
current limit by R803.
Speaker amplifier is in stand-by position (low current-consumption) when there is no
blas voltage in connector X820/5.

10.0.1 Principles Of Audio Operation
Audio is split into three sections, according to part-numbers:
TX-AUDIO
Regulator
RX-AUDIO

parts 200 ... 289
parts 290 ... 299
parts 300 ... 399

10.0.2 TX-Audio
I382 works as input buffer and attenuator and band-pass-filter (300 Hz...3.4 kHz).
I220 and I384D control the microphone line VOL in VOX mode (range c.20 dB), and
function as two-step limiters (c. 1 dB, 3 dB) in normal use. Yhe circuits combine the
TXAUXOUT and DTMFTX signals too.
I210A act as MICDET AC/DC conventer.
I384C act as dynamic compressor which is passed-by I390B.
C234 and R234 set a 6 dB pre-emph, and I235A act as amplifier.
I235B form a first maximum deviation limiter.
I382D form a second limiter and a low-pass-filter with the cut-off frequency of 3.4
kHz.
I382E act as the band-pass-filter of FII signal.
I210B combines FII and FFSKT signals, which are fed through the TXAUDIO line to
the synthesizer.
VR is modulated to VFF-voltage for I205C modem connection.

10.0.3 RX-Audio
I382 serves as an amplifier for reciever signals, or an attenuator in AUDLOOPON
mode. From I382F the FII signal branches to TXAUDIO. In the other branch, I382F
filters audio signal (300 Hz...3,4 kHz) and forms a 6 dB de-emph.
I384E works as an attenuator to expandor which is passed-by I390C.
I321A act as ERPDET AC/DC converter.
I361 and I321 together give VOL-control on SPK-line (control range +15...-10 dB),
and also combine DTMF signals. The control is also used in VOX mode. VPS is
modulated to VDref-half-voltage for I321B.

Half-voltage goes also to DTMF switch I305A.
I331 and I342A together give VOL-control on ERP-line (control rante +15 dB...-10
dB).
I342 is an amplifier for the system-cable.

10.0.4 Regulator
I380 regulate 9 V to 5 V (VR). Q295 switch on VPS-voltage to the audio parts.
The processor provides 4 MHz clock frequency for the CMOS switched capasitor filter of which parts B, D, E and F are filters and A generates half-voltage Vbias.
I384A generates half-voltages Vref and VTref. B part is an expandor, C part is an
compressor and D and E parts are amplifiers.

- Limiter settings can be checked with local 39*, DEVLIM.

10.0.17 Deviation Limiter
There is an SW controlled deviation limiter in the phone. The purpose of the deviation limiter is to compress microphone levels which causes maximum deviation and
distortion to transmitted voice.
Deviation limiter is tuned during manufacturing.
There are two thresholds in the limiter. When microphone signal is above tuned
threshold the limiter attenuates it. Attenuation is 0.8 dB when microphone signal is
above the first threshold and 2.7 dB when above the second.

10.0.18 Voice Operated HF
10.0.18.1 General:
Voice operated HF software uses microphone and speaker level detectors to measure, and TX and RX attenuators to set the microphone and speaker signals.
Voice operated HF is designed in such a way that a detected microphone signal
above tuned HF threshold always attenuates the speaker signal.
Microphone threshold is tuned in LOCAL by installer to work properly in the vehicle
where the phone is used.

10.0.18.2 Seesaw Model Of The Voice Operated HF
1. When microphone signal rises above tuned threshold the TX attenuation is
decreased and RX attenuation is increased.
Note: The deviation limiter may work which causes some TX attenuation.

2. When microphone signal drops below tuned threshold TX attenuation is increased
and RX attenuation is decreased.
Note: The actual RX attenuation minimum depends on user preset speaker volume
level.

3. When there are simultaneous speaker and microphone signals HF is set in duplex
state where TX and RX attenuators are in middle positions.
Note: The actual RX attenuation depends on user preset speaker volume level.

10.1 Processor Functions
All audio and processor functions of the radio are located on the same PCB; other
modules are interconnected through it. Only the RF-signals have a different route.
The processor controls the audio and radio units and the handset.

10.1.3.2 Functions
The I050 is the processor circuit. It includes the CPU, the 512*8bit EEPROM, timers
A/D converters and serial and parallel I/O lines. The X052 is an 8 MHz clock oscillator; diving this by a factor of 4 gives timing signal E.
While the processor is working, RESET is 5 V, VCC is 5 V, E is 2MHz; AS, R/W, and
AO...A15 pulses must change between 0 and 5 V.
The address codes for memory circuits and external I/O-circuits are made with
I103...I107. The chipselects CSR, CSP and CSIO are 0-active.
The FFSK modem I065 has its own clock X065 4.032 MHz. The modem is connected to CPU by serial lines, reception is connected to the syncron gate, and transmission is controlled by IRQ-interrupt. The modem gives 1200 Hz clock pulses
RXCLK and TXCLK to the processor.
The data detector is located in the modem, and its speed is determined by C070 and
C073.
The 4 MHz clock required by the audio circuit is obtained by dividing the CPU clocksignal with I062.
C040 and R040 sense the length of voltage break, the voltage drops during the
break, after which the voltage is measured with an A/D converter. The time constant
is approx. 10 seconds.
The program memory is in 64k*8 EPROM and it uses the addresses
4000H...FFFFH.
The RAM memory is in 8k*8 CMOS RAM using addresses 0000H...1FFFH. The
power supply to RAM has three different paths: in normal use through D133, when
the radio is OFF, the D135 regulates the voltage, and when the battery power is disconnected, the RAM gets its supply from A135 (3 V lithium battery).
Voltage control circuit Q128, Q130, and D126 stops the processor, and resets the
control functions when the supply voltage drops below 7 V. When the voltage
exceeds 8 V, the processor is restarted. The power supply switch logic I118 is also
connected to RAM supply in order to maintain proper RAM functions when the radio
is off.
The power switch (PWRSW) is ground-connected, and activates the current relay
while pressed. The program starts and checks the PWRSWS line to ensure that the
button is pressed and sets the current relay to hold mode on the PWRCTRL line. If
the power switch is pressed a long time, the program trips to the PWROFF line. The
C1231 and R123 maintains stored control during a short voltage break, i.e the relay
becomes active again when the voltage comes back within 10 seconds. It also works
as a control circuit in case of prolonged voltage-drop or processor malfunction and
after 10 seconds the radio will switch off.

While the IGN line is connected, the radio is switched on when IGN rises to 12 V.
The radio is switched off by the mains switch or by the handset-programmable timer
(0...99 h) when IGN goes to 0.
The buffers of the i2c path (to the handset) are Q138, Q139 and I094C,D.
The external (outside CPU) I/O gates I090...I094are 8-bit addressable latches. DATA
is sent ot the output determined by three address lines. When the RESET line goes
down, it closes all outputs down too.
The input circuit I096 works correspondingly, except that there are inputs instead of
outputs.
The DTMF receiver I097 gives an StD pulse at the beginning of the tone and the
data is then in lines Q0...Q3. The StD closes down when the tone signal finishes.
The DTMF generator I099 is I2c bus controlled. It forms DTMF tones and all radio
tone signals. The crystal X099works as a common clock for both DTMF circuits and
it is controlled by the program.
The transmitter control logic sets the TX power to the right level and turns the power
off. The TXVCO signal sets the transmitter to standby mode (bias on), the TX0 and
TX1 set the power levels and the TXON turns the power on and off.

interrupt for I2C path
microphone audio-ground
microphone HF input
microphone output, PWR
(normal deviation 1 Vrms)
(PWR, 5 V / 0 V)

11.0.2 Audio
I202 A and B are parallel audio-switches, and operate the earphone audio functions.
Operational amplifiers I206 A and B are inter-connected and provide a push-pull
input for the earphone capsule. Components 270-272 constitute a HOOK connection.
Audio switches I230 A and B activate either the normal- (A223) or HF-microphone.
I228B works as preamplifier for both microphones, and I228A is an active low-pass
filter, having a cut-off frequency of approx 3400 Hz. I230 C and D are parallel
switches for microphone audio.

11.0.3 Automatic Control For Keyboard And Lcd Backlight
Light dependable resistor (R130) controls I135A, which feeds transistor Q132. Q132
adjusts supply voltage (about 6...8V) to the backlight leds. IC circuit I135B switches
off the lights totally when ambient lighting increases enough.

11.0.4 Leds
LEDs D141-D146 illuminate LCD, and D151-D164 illuminate the keyboard. The
radio may turn both of them separately on and off. In bright light, the illumination is
also turned off by the dimmer-control.

Symbol- LEDs D171, D173, D175, D177, D179, and D180 can all be individually
switched on and off. They have no brightness control. The LED series resistors
adjus LEDs of different colors to the same brightness. All LED controls come from
I130, which is an I/O circuit controlled by I2C path. Pins A0, A1 and A2 are used for
coding all circuits to different path addresses so that the radio can control them individually.

11.0.5 Keyboard
The keyboard is controlled primarily by I110, and partly by I120. The keyboard base
is rubber matting, and the contacts are PCB foils. The I/O-lines of I120 have been
determined as outputs, and the I110 I/O-lines are all inputs. In stand-by, the inputs
are at 5 V, and the outputs are at 0 V. When a key is pressed, I110 activates interrupt
(I2CINT-line goes to zero), and the radio scans the keyboard matrix until it locates
the pressed key. Each of the outputs P0...P2 (I220) alternates between 5 V and 0 V,
and the states are read via I110.

11.0.5.1 Display
I100 is an I2C path-controlled display control-circuit. It controls the LCD- display
directly with 44 outputs. The display is 4/1-multiplexed. There are 4x40 (=160) individually controlled LCD segments.
R103 determines the multiplexing frequency, and R100-R102 provide LCD temperature compensation.

11.0.5.2 Power Supply
I261 is a 5 V regulator, which drops the 9 V voltage coming from the radio to a 5 V
voltage for logic circuits. There is separate regulator for LCD: D264, which provides
a voltage of 5.6 V (the temperature compensation requires more than 5 V).

12.0 DATA-INTERFACE FUNCTION OUTLINE
OO0402

The data-interface can be divided into three functional parts: the processor, audio,
and ring and line voltage circuits. Circuit diagrams are also separated into these
three sections.

12.0.1 The Processor
The processor function is provided by I010 MC68HC11 chip, which uses a 3.57 MHz
crystal X010. Program memory is provided by 64k*8 EPROM I030. Program memory and external I/O circuit address coding is performed by I050 and I060.
Communication between the processor and the radio unit uses an IIC-bus connected to I070, I080, I090 and I100. Each chip is connected to the processor databus with latch circuit.
The battery supported IIC-RAM I120 is connected to the processor IIC bus. The circuit is set to "power-saving" mode by inverting the regulator I001 ERROR output
with Q121.
The DTMF receiver I040 interprets codes sent from the tele-VDU and feeds them to
the processor through the I/O port. The oscillator I040 input is connected to the processor’s oscillator output.
The logical +5V power supply is regulated by I001, the ERROR output of which is
used to reset the processor.

12.0.3 Interrupts
The DTMF-receiver I040 StD output is activated by the circuit detecting a DTMF signal. This generates an "input capture" timer-interrupt to processor I010 (PAO/IC3).
Keyed in numeric codes (inc. * and #) are saved in the number buffer, with room for
23 digits. As the number buffer becomes full, further input is ignored.
The first DTMF code received suppresses the dialling tone by grounding the audio
frequency generator processor pins PA5/OC4, PA5/OC3 and PA6/OC2. A DTMF
interrupt activates a 7 second timer which will also display "number ready" mode.

28.1.1999

The system clock’s interrupt interval is 9.15424 ms. The clock updates the SW
counters, which are used for timing functions, dialling-tone formation (call, dial,
busy), and directing the adapter transfer modes.
The timer PA5/OC3 is used to generate a 25 Hz call tone. The relevent frequency
half-cycle is loaded into register TOC3; pin OC3 connected as the output pin (TCTL1
register); the OC3 interrupt flag is nullified in register RFLG1 and an interrupt is
allowed by activating the relevant interrupt-bit in register TMSK1.
When the ouput-compare register corresponds to the reference clock value, the
interrupt is completed and a new half-cycle reading is loaded into register TOC3.
The output square-wave is of 25 Hz frequency. Call-tone duration is governed by the
above mentioned system-clock interrupts from the synchronised SW counters.
Dialling- and busy-tones are formed using PA4/PC4 output. The frequency in both
cases is 425 Hz. Busy-tone cycle is 300/300 ms. Tone generation is similar to the
process described above. (Dialling-tone is not broken by the SW counters). The
PA6/OC2 output is reserved for generation of a tariff-pulse (16 kHz). This is not in
use with the data-interface.

12.0.4 Processor I/O Functions
During an input-capture interrupt, DTMF data is read from gate E pins PE0 ... PE3.
EXAL (incoming call) is registered at E gate pin PE4.
TERMHOOK (accessory hook) is registered at gate A pin PA2.
IN USE (PD3) control activates the data-interface and prevents simultaneous operation of tele-VDU and accessories.
RING GATE (PD5) - 120V regulator required for data-interface call functions.
IIC RAM circuit I120 data and clock (PA7, PF4). Included is a pulse counter for use
with the coin-operated version. The data-interface uses this circuit to store call data
(ACALL and BCALL data).
In case of a power failure with the adapter in call-mode, the RAM memory will be
checked after reset, and operation will continue as before. If the call was terminated
before reset, then the adapter will function normally, switching to dial-mode when the
handset is lifted.
IIC LATCH ENABLE (PD0). Control for latch circuit I110. The circuit is used to transfer a key-code to the radio unit. IIC-interrupt to the radio is simulated as follows: keyin the required code to the latch circuit I110, de-activate the PD0 control and wait
until the latch circuit I071 can be read by the radio prompted keyboard scan. For
each scan, the relevant code is written via PD0-control to I110. Finally, the corresponding key release interrupt is simulated.
Call-mode is recognised by reading the CALL-led state from circuit I081. Continuous
illumination of the led for one second during calibration indicates call-mode.

12.0.5 Audio
The telephone connection branch is formed by the operational amplifier I215. The
branch is matched to 820R/38 nF line impedance with resistors R218, R219 and
condensator C218. The telephone line, with +- 3.0 kHz deviation (1 kHz) and 3/7
loudness (400 mVrms), has a 600 Ohm resistive load with a -28 dBm signal level.
Similarly, a -3dBm input level will provide 1.0 Vrms in the TXAUDIO line, with +- 3.0
kHz deviation in the transmitter.
Audio tones (425 Hz) are filtered with the operational amplifier I205A, and then fed
through the branch to the telephone line.
Tariff pulses (12/16 kHz) are filtered with the operational amplifiers I235A, and are
fed to the standard current modulated telephone line.
The telephone line includes a return-feed constant current integrator I235, Q250,
and Q251, to provide the telephone line loop current. The constant current load
maintains the loop current supply without any loss of audio signal.
Loop current switching is detected from the transistor Q265 constant current load
emitter surplus potential.

12.0.6 Ring- And Line-voltage Power Supply
The telephone connection line-potential (60 V) is derived from a current form flyback
power supply.
During operation, the control-circuit I341 measures the current flowing through the
transformer primary windings at resistor R338. When the current exceeds the value
specified by the control circuit, FET Q335 is de-activated. This results in the energy
stored in the transformer being discharged from the secondary windings through
diode D328 to output condensators C329 and C328. When the output drops to the
value determined by resistors F342 and R343, the control circuit lowers the level at
which FET Q335 switches.
With RING-GATE control, offset-current is directed to the control circuit adjuster
through resistor R347, resulting in an output voltage of 120V during the ring.
The secondary current is limited with operational amplifier I205B, which measures
the transformer secondary current flowing through resistor R371, and when secondary current limit is exceeded 1205B adjusts the control-circuit 1341 via diode D367.
RING-control is normally in 0-state, and Q325 functions as a constant-current generator, providing a continuous voltage for FET Q323. This causes Q323 to conduct,
and the line-voltage is fed to the telephone line. During a call, RING-line alternates
between 1 and 0 at 25Hz, causing Q323 and Q326 to conduct in turn. As the powersupply voltage is raised to 120V in call-mode, the telephone line is provided with
both 60V DC and 60V AC voltages.

The audio signals are changed with relay A315 to the branch circuit with IN-USE
control. The diode D303 allows radio unit to be switched off if for some reason the
call cannot be terminated from the VDU. FET Q317 breaks the SDA-line, so that the
keyboard is inoperative while the tele-VDU is in use. The display functions as normal
as the diode D303 will permit writing to the screen.

13.0 INSTALLATION OF ANSWERING MACHINE
The answering machine is installed inside the transceiver unit.
Place the transceiver unit on the table, the cooling plate away from yourself, so that
the antenna connector is on its right side and the power connector on its left side, figure 1.

Unscrew the head bolts, and remove the cover. Now you can see thr Audio/Processor voard and on its right side the connector-strip A, to which the answering machine
is connected, figure 2.

13.1 Answering Machine
13.1.1 Processor
The central processing unit for the answering machine is Intel 80C31. The processor
- reads the PROM program memory
- stores the speech, digitized with the delta-modulator, in DRAM memory, and
tran stored speech from RAM to the delta-modulator,
- refreshes DRAM circuits
- communicates via the I2c bus with other devices connected to the system,
- controls the audio signal path control switches,
- controls the ringing tone signal,
- generates the "watchdog" reset pulse.

13.1.2 Memory Control
The processor may uses the program memory D190 and the dynamic RAM D200D220.
The memory addressing timing functions are assisted by control logic. The processor refreshes the dynamic RAM circuits at 8 ms intervals.

13.1.3 Watchdog
D110C resonates at a frequency of approx 3 kHz, independent of the processor.
This logic-level pulse is led to the counter D260. The watchdog reset pulse of the
processor zeroes this counter at 8 ms intervals. There is no reset pulse when the
program malfuctions. In that case the counter is free to proceed so that the counter
D260A MSB will reset the processor.

13.1.4 Audio Paths
The answering machine recognizes the audio signals coming from TXAIN- and
RXAIN-lines. It transmits an audio signal to TXAOUT- and RXAOUT- lines.
N230A ampflies the incoming audio signals. N240B is a compressor which drops the
incoming audio signal dynamics to an appropriate level for the delta modulator.
N170 is a delta modulator which converts the incoming audio signal to serial data.
When repeating the stored speech, N170 converts the serial data coming from the
memoriesn to an analog signal, which is led to the buffer amplifier N230d. The signal
goes forward to the expander N240C, which then expands the comperssed speech
dynamics to the original level. The compressor is followed by an active low-pass filter on which the processor-generated ringing-tone signal is combined. The last unit
is the buffer amplifier N230C. The signal coming from N230C is led to either

Product: Answering Machine /
28.1.1999

RXAOUT- or TXAOUT-line with CMOS- switches N250C and N250D.

13.1.5 ICC-Operation
Communication between the radio unit and the answering machine is accomplished
with an IIC-bus (lines SDA, IICINT, and IICENA). When necessary, the radio unit can
disconnect the SCL-line with N140D. There is an open-collector output (V291) on
the IICINT-line; the up-draught resistor is at the radio unit.

13.1.6 Operating Voltages
The answering machine gets its operating voltage from the radio unit (X290).
The operating voltage range of the answering machine is 10.6 - 16 V dc. In stand-by,
the current consumption is approx 20 mA; when recording and repeating speech, it
is approx
90 mA.
