KX-TCD951GB/KX-TCD955GC 2. THE LINE INTERFACE SECTION (SEE BLOCK DIAGRAM Fig. 18)
2.1 INTRODUCTION This section consists of the telephone line interface, bell detector, charge-pulse detector, hook switch, pulse dialing circuits, audio circuits, DC mask & line impedance circuits, power supplies, and battery charger circuits. 2.2 TELEPHONE LINE INTERFACE (SEE Fig. 21) The telephone line is connected (via 2 or 3 jumpers selected for country of destination) to a JMP19 and JMP20. Surge suppressor SA3 protects against excessive line voltages. Test points are TP14 (A), TP13 (B), TP21 (S) and TP15 (E). A 16 kHz notch filter L3, L5, C5 and C26 blocks the 16 kHz charge pulse signal from the rest of the line input circuitry. Bridge rectifier D8 provides for lines of either polarity. The output of D8 is Line + (TP39) and Line which is ground. 2.3 EARTH RECALL (SEE Fig. 21) For countries that require Earth Recall facilities, relay RLY1 is provided to short the E line to the A or B lines. The relay is energized when transistor T2 is switched on by a high level on the EARTH control line from the BB-IC IC101. D1 will quench the large back-emf voltage that would otherwise occur across the relay coil when T2 turns off. 2.4 BELL DETECTOR (SEE Fig. 21) The AC ringing signal is detected by optocoupler IC2, using its internal diode in conjunction with D4. DC from the line is blocked by C2. The other components D2, D3, and R3 reduce current and increase the circuit impedance in line with national requirements. When ringing is detected IC2 will turn on, and the RING line will be dragged to a low voltage. Circuit Diagram

CIRCUIT OPERATION (HANDSET)
1. THE BASE-BAND SECTION (SEE BLOCK DIAGRAM Fig. 25)
1.1 INTRODUCTION The base-band section consists of a base-band integrated circuit (BBIC), a Flash PROM, an EEPROM, an LCD Display, a Microphone, an Earpiece, and power supply/battery management circuits. 1.2 THE BASE-BAND INTEGRATED CIRCUIT (BBIC) The National SC14404 BBIC (IC1) is a CMOS device designed to handle all the audio, signal and data processing needed in a DECT handset. It contains two microprocessors - one general purpose - while the other burst mode controller takes care of DECT specific physical layer and radio section control. The BBIC also contains the ADPCM transcoders, a low power 14 bit codec (ADC/DAC), various other ADCs, DACs and timers, a UART for data communication with RF unit, a gaussian filter for the DECT GFSK modulation method, clock and data recovery circuits, a clock oscillator circuit, a battery management circuit, and a pair of gain controllable amplifiers for the microphone and earpiece. On some handset models, the Flash ROM will also be contained within the BBIC. Circuit Diagram

Fig.26 31

1.6 AUDIO PATH - TX AUDIO (SEE Fig. 28) Balanced audio from the microphone (TP40 and TP41) enters the BBIC at pins 61 and 63. A balanced bias voltage for the (electret type) microphone is supplied by the BBIC from pins 60 and 64 via R31 and R32. This supply is de-coupled by R22, R27, C21, C28, and C22. RF de-coupling of the microphone signal is provided by R27, C25, R28, C26, R24, R25, and C20. The microphone audio signals are coupled to the BBIC via C22 and C23, which provide some high pass filtering. In the BBIC audio passes through the gain-controlled microphone amplifier, into the ADC part of the codec, where it is sampled and turned into digital data. The burst mode controller then processes this raw data (called the B-field) performing encryption and scrambling, adding the various other fields that go together to produce the GAP standard DECT frame, assigning to a time slot and channel etc. The data then passes through the gaussian filter to emerge on pin 20 as TRADAT. 1.7 AUDIO PATH - RX AUDIO (SEE Fig. 28) Audio from the receiver RECDAT (TP54) enters the BBIC on pin 18 and passes through the clock recovery circuit. The burst mode controller separates out the B-field data, and performs de-encryption and de-scrambling as required. It then goes to the DAC part of the codec where data is turned back into analogue audio. The audio signal is amplified by the gain-controlled earpiece amplifier, and balanced audio is output on pins 65 and 66, and fed to the earpiece (TP31 and TP32). The leads feeding the earpiece are RF de-coupled by C15 to R22, C17, C16, R23, and C18. C19 provides low pass filtering.
