RAE2 General Information
Introduction
RAE2N is the 2nd generation communicator for GSM 900 network. Communicator extends the basic digital cellular phone with inbuilt data capabilities and applications. RAE 2 is a phase 2, class4 transceiver with 2W peak TX power. The device has two user interfaces. The conventional phone interface on the front cover. By opening the device the user can access the graphical user interface which can utilize the full communicator functionality.
Technical Summary
The Communicator is divided into two main domains: phone and personal digital assistant (PDA). Phone manages speech and data connections to GSM network. It also handles audio input and output. PDA runs all the applications (e.g. calendar, contact database etc...) and utilizes the data connections made by the phone. The phone is based on DCT3 technology and CUI style user interface software. PDA uses AMD's 486 CPU and GEOS operating system. Battery technology is Liion. The product has earpiece for conventional phone use but it also has an internal handsfree speaker. Connection to the other devices can be handled with 115kbps serial cable or 115kbps IR. Product is IrDA compatible.

PAMS Technical Documentation
The phone display is graphical, transflective FSTN LCD display. Display resolution is 84x48 pixels. The PDA display is graphical, transflective FSTN LCD display. Display resolution is 640x200 pixels and dot pitch is 0.17mm. Contrast is good enough to show 16 gray scales. Both LCD displays are backlit with ELpanel. In addition to the fixed memory the product can use memory extension module, MMC, to expand the user file system area. The MMC supports hot insertion. NOTE: Due to the infrared data link the RAE2 is officially specificed as : CLASS 1 LASER PRODUCT. See IEC 608251 specification 8251; Labelling, 5.1 General 5.2 Class 1.
Product Selection
The product has only one design, however each user interface language version has its own product code. Some countries have e.g. English communicator but manuals in the local language.

User Interface specifications
The product has tho separate user interfaces (UI): CMT UI on the front cover and PDA UI which can be accessed by opening the device. CMT UI conforms to Jackstyle defined by NMP. The detailed feature list and UI specifications can be found in PCMS.
User Interface Features
The RAE2 has two separate user interfaces (UI): CMT UI on the front cover and PDA UI which can be accessed by opening the device. Highlights of the CMT interface are:
Graphical user interface, scalable text.
Separate PROFILEbutton for selecting CMT profile
Voice recorder can be activated from UI.
PDA UI is based on the previous Nokia Communicator product, N9000. The main difference is that leftmost scroll buttons are replaced by Menu, Zoom and Backlight buttons.

Menu
Zoom Backlight Menubutton activates an additional popup menu window. The contents of the window depend on the current application. They can be e.g. settings for the telephone application. Zoombutton toggles the font size of certain views. The zoomable view depends on the current application. The device has three different zoom levels. Backlightbutton activates the backlight for a preset period or until the button is pressed again. Backlight makes it possible to use the product in low light conditions.

Functional Description
The Communicator comprises two functionally independent units: PDA and CMT. The PDA implements the communicator application platform. The CMT implements the GSM transceiver and basic data functionality, both transparent and nontransparent data. All UI functionality is combined into one UI module (BS2) but both PDA and CMT control their respective UI independently. The Functional units and the implementation differ slightly. Due to mechanical reasons some components are placed into a different module than they functionally belong. E.g. audio components are placed into BS1 (PDA) module even if they functionally belong to the CMT.

PDA Module
The PDA modules has its own power management chip, the Phaser. The Phaser regulates the voltages for PDA components. It also controls PDA powerup/down procedure by providing POWERGOOD and RESET signals to Scotty. The PDA processor Scotty is an embedded 486 processor manufactured by AMD. The Scotty contains a set of PC peripherals except a parallel port. It also has some additional peripherals like LCD controller and MMC host controller which are not standard to PCs. CPU has a 8k cache. The PDA interfaces the CMT with 115kbps serial bus (FBUS). It also provides low frequency clock (32kHz) to CMT. PDA also can get information about CMT state (on/off) and wake up CMT.
CMT Module
The CMT is based on DCT3 engine and it is functionally the same. Sleep clock (32kHz) is received from PDA side. All the audio components are controlled by CMT (COBBA). It PDA wishes to play sounds those are first sent to CMT. Keyclicks and some system sounds are exceptions and are played directly by PDA.

Power Distribution
All the digital circuitry modules use 2.8V nominal operating voltage. Power is drawn from 1140mAh LiIon battery. Higher voltages are generated for LCD, SIM and backlighting. The diagram below describes the power distribution of the product.
Audio
The transceiver has two speakers; earpiece for the telephone interface and handsfree (HF) speaker. Different kind of tones can be played through speakers. HF speaker is driven only by CMT module. The earpiece can be driven either by the PDA or the CMT. The transceiver has one microphone connected to the CMT module. The speakers are used :

Software Specifications of Interfaces
CMT SW is based on HD943. This product program has added internal data functionality and ECI message interface.
External Devices
External devices can be connected through serial cable (DLR2) or IR. The protocols used are: IrOBEX (irconnectivity), UltraIR (DCT3 connectivity), IrDA (PCconnectivity) IrTranP (camera connectivity). The PC connectivity uses a specific PCCOM protocol on top of the IrDA or serial connection.
Interfaces Between Transceiver Processors
PDA and CMT processors interface through serial FBUS channel. On top of the physical FBUS link two separate protocols are used. The Phonet protocol is used to transport CMT related control information and dataframes. "RBUS" is used to transport ECI (External Control Interface) messages between PDA UI and CMT.
SoftwareHardware Interface
CMT sw/hw interface is the same as hd940 is using. PDA software is running on AMD Elan SC450 processor. Operating frequency is 33MHz.

PDA HW Module (BS1)
The lowest level of HW/SW interface is handled by the BIOS which provides some basic services for upper sw layers. E.g. read data from memory card. Testmode is used by production and After Sales. It provides the interface to test and program PDA and CMT modules. DOS layer implements only a subset of DOS functions known from conventional PC. DOS is used mainly in testmode and to launch GEOS. GEOS is the basic SW platform to all applications that user sees. It however interfaces directly to some HW resources, like LCD display or serial ports, by its own HW drivers.
Alignment
Both PDA and CMT modules require alignment. Alignment is done at module level to modules BS8 and BS1. LCD temperature measurement can be done only after the assembly of the product. The following parameters are adjusted in CMT module (BS8): TX power, RSSI, AFC ,TX I&Q, battery voltage and charging current. PDA module (BS1) needs alignment of: battery voltage, LCD contrast voltage. Alignment is software based. Predefined reference point measurements are stored into EEPROM (CMT) or flash (PDA).

Flashing
Product requires two separate flash images for executable code: one for the CMT and one for the PDA system. Language versions are held in separate files. CMT flashing uses partly the same equipment as other DCT3 family products. PDA flashing can be done with JTAG (low level flashing) or WinTesla. WinTesla flashing is recommended.
