Initialization When the handset is on cradle or base power supply restored after interruption, the base unit sends the follow ing information through charging contacts: • Updated Security Code • Control channel data including transmission frequency The transmission frequency is determined after checking the last used channel to make sure it is vacant. This ensures that the handset has a clean channel to use. If the last used channel is occupied, the base unit will scan to find a vacant channel. The base unit will send the above information to the handset 9 times. Once the handset receives the channel-acquire command, it will update its security code and transmission frequency. Base Unit Handset Detection of Handset Charging 9 Data Packets Only Security Code + Control Channel Data (Wire System) After the “ACQ + Channel” command is received, the “Reply” command will be sent continuously for about 200 packets through wireless system of the new control channel. Security OK Command Security OK Command When “RESP” command is received, 9 consecutive commands of Security OK will then be sent out. After a channel is selected successfully, the “ACQ + Channel” command will be sent.

No part may be reproduced or used except as authorized by written permission. Channel Scanning There are totally 20 channels with frequency allocation shown in the Technical Description. Once the handset is on cradle or the base resumes power, the security code along with the channel number are sent to the handset. The base will scan a channel and detect if there is any carrier in that channel. If that channel has no carrier, that means the channel is “clean”. The handset can request the base to change to another clear channel. This is done by first sending a “Link up command” to the base. The base will search a clean channel and send the “Channel response command” to the handset. After receiving the “Channel response command”, the handset will then send the “Channel command” to the base. Upon receiving this command, the base acknowledges by sending the “Change channel response command” to the handset. 4 When the “Change Channel Resp” command is received, Handset will stop sending “Change Channel Resp” command. Handset Base will switch to the chosen channel and send the “Channel Response” command continuously for about 5 seconds. Receiving the “Change Channel” command, Base will change the transmit and receive to a new channel and send the “Change Channel Resp” command to Handset After checking out the empty channel, the Handset sends the “Link Request” command for max. 5 s…

No part may be reproduced or used except as authorized by written permission. GENERAL CONCEPT The PRF500 telephone is a radio transceiver designed to make or receive a telephone call without connecting a wire between the handset and the base station unit. Physically, PRF500 is equipped with two separate parts. The first part is the base unit. The base unit houses 2 physically separated hardware systems, namely phone system and Personal Data Assistant (PDA) docking system. The phone system functions as the base unit of the cordless phone, communicating with the handset and interfacing with phone line. This system includes a wide band transceiver and a telephone line interface. The PDA docking system is for docking of the PDA and interfacing with PC via a cable. The second part of PRF500 is a piggy-back handset module plugged into the expansion slot of the PDA, sharing the LCD of the PDA for telephone functionality. This handset module consists of a wide band FM transceiver, earpiece and headset jack. Once plugged into the PDA, the handset module will utilize the PDA’s LCD touch screen dialpad and microphone to function as a cordless phone handset. The phone system of the base unit and the handset module are operating in full duplex mode on one of the 20 channels in 902-928 MHz band. Their linking can only be achieved by means of a matched security code to prevent unauthorized access to one’s telephone line. There are up to 16.8 million (24-bit) digital security codes set by the microprocessor software. The detailed explanation of the theory of cordless phone system operation is described in the following sections.

No part may be reproduced or used except as authorized by written permission. 1.FUNCTIONAL DESCRIPTION OF BASE UNIT (See Section on BLOCK DIAGRAM) 1.1Microprocessor The 8-bit MCU U201 operates at 8 MHz resonator frequency and on 5V DC. The device provides digitally generated DTMF. Other I/O pins are used to activate hook switch and LED indication, to page the handset, to detect cradle signal, extension phone and incoming ring, to activate data transfer to PC through Hot Sync, and for various controls such as Rx data and Tx data. An external power- up reset is incorporated to prevent the MCU from hanging. Internal watchdog is utilized to minimize erratic software operation. 1.2CID DECODING The CID Decoder IC U501 with Visual Message Waiting Indicator supports both on-hook and off-hook CID. When U501 detects CID in an incoming ring during standby mode, it activates the FSK signal decoding section. The incoming FSK signal from Tip/Ring is converted into digital data. The data (1 byte) is buffered in the decoder, waiting to be latched out by the MCU until the next byte comes in. After processing the CID data, the CID Decoder sends the CID data through the Tx data path to the Handset. When there is a second incoming call and the phone is in talk mode, phone call alert message will appear on the PDA screen. 1.3Ring Detect The ring detect circuit detects the presence of an incoming ringing signal. When the ringing voltage exceeds 40 Vrms, a current will flow through the LED section of the optocoupler U901. The output transistor of the optocoupler will give logic signal to the MCU in accordance with the frequency and cadence of the incoming ring. 1.4Battery Charging The voltage supply for this charging unit is 9V DC from the AC power adaptor. A series resistor in the circuit limits the maximum charging current.

No part may be reproduced or used except as authorized by written permission. 1.5 Cradle data When handset is on the base, on-cradle is detected by Q102. MCU will send out command data through an inverter Q101 to the charging contacts and hence to the handset. 1.6 Baseband Signal Processor 2.6.1 Transmit Audio The audio signal from the phone line interface is amplified by U301C before it is sent to RF module. 2.6.2 Receive Audio The demodulated audio from the RF module is amplified by U301A and U301D before it is sent to the phone line interface. 1.7Line Interface At the line interface, the transformer T901 and optocouplers U901/U902 provide isolation between the phone network and the Base. The transformer also acts as a 2-to-4-wire hybrid network for transmit, receive, and sidetone signals to and from the telephone line. For protection against surges, there are two major protective components. The first one is a fuse FU901 that will open when there is large in-rush current (250 mA or more). The second one is a 275Vrms varistor VS901 which will limit the maximum voltage induced across the telephone line. High voltage capacitors C904 and C905 with 2kV isolation capability are provided for CID detection circuitry. 1.8RF Module The RF modules of the base and handset share the same design except that the transmit and the receive frequencies are interchanged and different Duplexer types are used due to space constraint.
