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 Channel ACCH
– Analog Voice Channel AVCH
– Digital mode, on 800 MHz band
– Digital Control Channel DCCH
– Digital Traffic Channel DTCH
– Digital mode, on 1900 MHz band
– Digital Control Channel DCCH
– Digital Traffic Channel DTCH
– 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-

System Module UT5U
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.

Battery voltage VBAT is connected to CCONT which regulates the supply
voltages VBB, VR1–VR7, VSIM and V5V. CCONT enables automatically
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.
