3 OVER VIEWThis chapter describes the hardware overview of the Voice Processing System (VPS).
3.1. SYSTEM OUTLINEThe Panasonic Voice Processing System (VPS) is a voice prompted, menu-driven system which provides fully automated calltransfer (to an extension or mailbox), and voice message receiving and delivery service. Even first-time users can easily reachtheir desired extension or mailbox by following step-by-step voice instructions.The VPS works with a PBX as an extension. It can be expanded to handle up to two simultaneous calls and store up to fourhours of voice data.The VPS attends to incoming calls, then transfers those calls to the respective extensions. When owners of extensions cannotanswer the call, the mailboxes in the system take messages for them. Owners of the mailboxes can record personal greetingmessages with their own voice for callers who enter the mailbox to leave messages.The VPS has up to 62 personal mailboxes for subscribers and two special function mailboxes for the System Manager and
Message Manager.The VPS can be used by any caller, and by subscribers (Mailbox Owner) in your company.Even if the user is away from the office, VPS can be used with any touch tone telephone.Even callers using a rotary telephone can leave messages or be connected with the operator.
3.1.1. Automated Attendant (A.A.) Service
The automated Attendant works as a receptionist would by answering incoming calls without using human intervention.The Automated Attendant plays a list of options (calling extension, calling operator, Deparment Dialing, Dialing by Name) to acaller with a voice prompt. When an option has been selected, the Automated Attendant responds to the command by eitherrouting the caller to an extension or the operator. The Automated Attendant will even respond if the extension is busy or if thereis no answer.One option is to let the caller leave a message in a mail box.
3.1.2. Voice Mail (V.M.) Service
Voice Mail is a voice message receiving and delivery service which allows subscribers (the owner of a personal mailbox) toreceive messages in their mail box whether they are out of the office, on the line, or just unavailable to answer the call.Any caller can leave a message in a subscriber´s mailbox. The subscriber can listen, transfer, and deliver recorded messages
at any time from anywhere in the world.
3.1.3. Interview Service
You can set up a questionnaire mailbox with as many as 10 questions, and obtain specific information from customers callinginto the system. Between each recorded question, the VPS collects a reply from the caller and stores it in a mailbox.This service is ideal for gathering any data from product orders to requests for repairs.
3.1.4. Custom Service
The Custom Service capabilty optimizes the application of the VPS to meet your business needs. Your callers can access theservices or people they need by pressing a single digit on their telephone keypad. As many as two custom service scripts canbe assigned to each VPS port (Day Service and Night Service).

3.2. SYSTEM PROGRAMMINGThis system can be programmed either by a data terminal (VT100, compatibles, or other ASCII Terminals) through the SystemAdministrator Interface or by telephone (touch tone telephone) through the System Manager mailbox.
3.2.1. Terminal Based Programming
After system installation, it is recommended that you perform "Quick Setup" first.
<Quick Setup>
Provides a fast way of setting up the VPS for basic Voice Mail or Automated Attendant service. This includes mailbox creation,incoming call service assignment for all ports, time setting and several other programming items which must be done initially tostart the VPS operation.
<PBX Integration>
The VPS is a 2 port system . Typically, each VPS port is connected to an extension port of the PBX. Between PBX´s, the VPSexchanges a request to a counterparty or status for itself mutually, then offers a quick and useful service. The VPS works wellwith all Panasonic KX-T series PBX´s and can be programmed to work with most other manufacturer´s PBX´s that fully supportsingle line telephone interfaces.However, because the VPS operation depends on the capabilities and features provided by the PBX, it´s performance will vary
when connected to different PBX´s. In system program, Integration Parameter with a PBX should be installed to achieve aquicker and useful service.
3.2.2. Telephone Based Programming
During daily operation, the person specified as the System Manager can create and/or delete mailboxes, and change Class ofService parameters.

3.4.3. Basic Components
Fig. 4. Basic Components Location
The basic Components of the VPS are Main Board, Flash Memory Card, Power Board and LED Board. (Refer to Figure 4.)
1. MAIN Board
The next 3 blocks of the main board are explained. All of these VPS functions are generalized.
Interface Block;
This constitutes the interface with PBX and has three kinds of interfaces, SLT/APT/DPT, at two ports. And this has the RS232Cinterface for connecting the PC terminal.
DSP Block;
This has the two-channel DSP. This DSP performs DTMF generation, DTMF detection, TONE detection and voicecompression/expanding.
Control Block;
This consists of CPU and the IDE interface for controlling the flash memory. CPU performs circuit control, peripheral devicecontrol and IDE interface control.
2. Flash Memory Cards
The flash memory cards are connected to the main board by CN105 and CN106. The flash memory card connected by CN105is called the master memory card. It stores the system program, system guidance and 2 hours of message recording area. Theflash memory card connected by CN106 is called the slave memory card: it can be installed as an option. By adding this option,the recording time of KX-TVP50 can be extended from 2 hours to 4 hours.
3. Power Board
Power input of AC 100 V - 240 V, 50Hz/ 60 Hz produces secondary power output of +15 V, +5.5 V or -5 V.
4. LED Board
The LED Board is connected to the Main Board via CN102 and is controlled by the Main Board.

4 INSTALLATIONPlease read the following precautions before installing the VPS
4.1. InstallationThe VPS needs to be installed on the wall. Improper placement of the system may result in malfunction, noise, or discoloration.Avoid installing the VPS in the following places:
· in direct sunlight; in hot, cold, or humid places
· in new areas where there are thermal springs, etc. (where sulfuric gas may damage the equipment or contacts).
· where shocks or vibrations are frequent or strong.
· in dusty places or places where water or oil may come in contact with the unit.
· on or near computers, telexes, or other office equipment; near microwave ovens or air conditioners. (Ideally, the VPS shouldnot be in the room with these items and should be at least 1.8m 6 feet away from televisions.)
Do not obstruct the areas around the PBX and the VPS. Both require space above for cooling and space on the sides formaintenance and inspection.
4.2. Wiring · Do not wire the telephone cable parallel to an AC power source, computer, telex, etc. If cables are run near those wires, shield
the cables with metal tubing or use shielded cables and ground the shields.
· Use protectors if running cables on the floor. Avoid running wire under carpets.
· Avoid sharing a AC 100 V - 240 V, 50 Hz / 60 Hz AC power supply for computers, telexes, and other office equipment with theVPS. Induction noise from such equipment may interrupt the VPS operation
When making any connections or removing the cover, be sure the power cable is disconnected.
· When installing telephone wiring, basic safety precautions should always be followed to reduce the risk of fire, electric shockand injury to persons, including the following:
· Use protectors if running cables on the floor. Avoid running wire under carpets.
· Use caution when installing or modifying telephone lines.

4.5.1. System Start-up
When you finish installing KX-TVP50, connect the power cable and start up the system.The LED turns on → blinks, and the PCterminal displays the start-up screen as follows.
Note:
1. When you implement a new flash memory card, its system software will be downloaded. So it will take 1 to 3 minutes for theLED to turn on → blink. But this is not a failure, so wait a few minutes until the start-up screen is displayed.
2. Never disconnect the power cable in the middle of the system start-up (while the start-up screen is displayed), otherwise thesystem software download and start-up program may not work properly.
18
KX-TVP50CE / KX-TVP52CE
4.6. CABLE CONNECTIONBefore connecting the power cable to an AC Inlet, make sure all other connections (RS-232C data terminal with VPS, PBX withVPS, PBX with telephone lines) are secure. Use the AC Inlet dedicated to the VPS unit.
CAUTION:
Disconnecting the power cable in the middle of the operation/process of the voice mail may cause trouble. When pullingout the power cord after installation, make aure that voice mail is OFF LINE by using the OFLN command or justly pull out theTEL cable and the RS232 cable, and then pull out the power cord of the voice mail.

6 HOW TO REPLACE THE FLAT PACKAGE ICIf you do not have the special tools (for example: SPOT HEATER) to remove the SPOT HEATER´S Flat IC, if you have solder(large amount), a soldering iron, and a cutter knife, you can easily remove the ICs even if there are more than 100 pins.
6.1. PREPARATION · SOLDER
Sparkle Solder 115A-1, 115B-1 OR Almit Solder KR-19, KR-19RMA
· Soldering iron
Recommended power consumption is between 30 W to 40 W.Temperature of Copper Rod 662 ± 50°F (350 ± 10°C)(An expert may handle a 60~80 W iron, but a beginner might damage the foil by overheating.)
· FluxHI115 Specific gravity 0.863(Original flux should be replaced daily.)
6.2. FLAT PACKAGE IC REMOVAL PROCEDURE 1. When all of the IC lead cannot be seen at the standard degree, fill with large quantities of solder.
Note:
If you do not fill with solder and directly cut the IC lead with the cutter, stress may build up directly in the P.C. board´spattern. And as a result 1 the P.C. board pattern may have to be removed.
2. Using a cutter, cut the lead at the source. (Cut the contents with a cutter lightly, 5 or 6 times.)
3. Remove when the solder melts. (Remove the lead at the same time.)
After removing the Flat IC and when attaching a new IC, remove any of the excess solder on the land using the soldering wire, etc.If the excess solder is not removed from the land, the IC will slip and not be attached properly.

7.2. THE FUNCTION EACH BLOCK DIAGRAM 1. RS-232C Interface
Serial communication is performed by the CPU´s communication processor using the RS-232C driver. This interface is used foreach setting of the voice mail.
2. Analog Interface
When the SLT interface or APT interface is used, the analog voice signal is the transmission/reception interface circuit with thePBX. It includes call forwarding control, CPC detection and call waiting detection functions.
3. 4-line/2-line conversion circuit
In order to construct the PBX interface, this circuit converts between the communication lines (2 lines) that perform primary linetransmission/reception, and the reception lines (4 lines). It includes a hardware echo canceller circuit utilizing phase inversion.
4. C-Tone Detection Circuit
A continuous tone detection SLIC for fax use is provided to detect input of fax communication signals.
5. CODEC
When the SLT interface or APT interface is used, the analog voice signal is converted into PCM digital data. When the DPTinterface is used, the digital serial voice signal from the PBX is returned to analog format and used for C-Tone detection.
6. KME-PBX APT Interface Driver
In order to integrate APT with the KME-PBX (TA Series), APT protocol transmission/reception is used on the H-L line. Drivercontrol is controlled by the CPU I/O port. Control of two channels, Ch1 and Ch2, is performed by the APT driver of Ch1 only.

8.1. System Resert
System reset uses the power monitor IC to monitor the +5 V power supply to the main board. If the supply voltage reaches 4.75V or above, after a time lag of approximately 180 mS due to the time constant of the R.C., the reset signal is changed from L ->H (RSTn). This signal is received by IC136, then input to the CPU (IC101), flash memory (IC102), RTC (IC128), the flash memorycard (master) and the flash memory card (slave). To prevent current intake, IC136 uses the CMOS IC. Simultaneously, the resetsignal (RST) inverted at IC109 is input to DSP IC120 (ACH), DSP IC120 (BCH), and gate array IC125.

8.2.6. External Bus Interface
The external bus interface contains 2 circuits, a CPU R/W signal shaping circuit and a bus latch circuit. When the R/W signalof MC68302 is directly connected to the external peripheral devices as a base signal, it is possible that the R/W control timingconstraints may be violated for the respective peripheral devices. Accordingly, this R/W signal shaping circuit waits for 4 cyclesto access the external peripheral devices. The R/W signal length from the CPU is lengthened, so the DTACK signal from theCPU alters the R/W signal so that it rises earlier than the CS and Ds signal. As a result, the constraint conditions required foraccess to the external peripheral devices may be fulfilled. As a result of this R/W signal shaping, it is possible that output of validdata from peripheral devices does not match the timing of CPU intake. To overcome this, a circuit has been added which firstlatches on to valid data output from the peripheral devices and retains it until taken in by the CPU. The peripheral devicesconnected to this external bus interface are the IDE interface, RTC, DSP and gate array.

8.2.9. RS-232C interface
The RS-232C interface is provided by SIO (Serial Input Output Controller) built-in the IC101.
1. Data Format
When a data character to be transmitted is placed in the SIO, the serial interface automatically adds one start bit before the databits (lower order bits are output first) and the specified number of stop bits after the data bits. When parity (even, odd) isspecified in the mode register, a parity bit is inserted before the stop bits.
Fig. 1 Data Frame
2. Data Transmission
The Microprocessor checks the DSR (IC101 - 63): Data Set Ready is low, i.e. terminal side´s preparation for receiving datafinishes, then starts transmission. After transmitting the start bit, the transmit controller automatically appends a parity bit andstop bits to the data character of the specified length and shifts these out to the TxD line. When the next data character hasbeen written to the transmit data buffer, transmission continues with the start bit of the next data character following the stopbit of the current data.
Fig. 2 Switchover Timing for Transmit Data Bits
3. Data Reception
The RxD line is high when no data is in it (mark status). The beginning of a start bit is detected when the input goes low.For receiving, the first low sampled RxD is detected and, if the sampled data are low for four internal CLKs, this low level isconsidered to be a valid start bit. The center point of the following data bits is then determined and each data bit is sampled onthe TCLK falling edge.

The Real Time Clock is provided by IC128. IC128 is a Real Time Clock IC with an eternity calender to be able to read and writefrom seconds. To interface with the Microprocessor four data buses=(LD<3-0>), four address buses=(LA<4-1>), two controlbuses (LIORN, LIOWN) and two chip select (RTCSN, MRSTN) are needed for set the time/modification/read out.
1. Microprocessor Read Cycle
Read timing of time data from IC308 by Microprocessor is shown in timing 4-12.
Fig. 5 Real Time Clock Read by Microprocessor
The Microprocessor (IC101) outputs valid Address to LA(4-1) in S1 state. Chip select Controller (IC116) asserts RTCSN in low.System Controller asserts LIORN to low in S2 state. To Respond to low assertion of LIORN, the IC128 outputs the internalresistor corresponding with LA(4-1). At that time to LD(3-0) the Microprocessor takes in effective data on LD(3-0) in the fallingedge of S6 state.

3. Battery Back Up Interface
IC128 possesses two motion conditions of operation mode and standby mode. Operation mode is guaranteed the interface withMicroprocessor and is the condition to be able to setting time/modification/read and write.If Provided more than 4/5 VDD voltage is relayed to the CS1 terminal (20 pin), it becomes the operation mode. If less than 1/5VDD voltage is relayed to the CS1 terminal (20 pin), it becomes the stand-by mode. By IC308 checking time function inside ICworks but the interface with Microprocessor is not guaranteed. In this mode the consumption of the current decreases. In orderto switch over these two modes (operation mode and stand-by mode), The MRSTN signal is connected to the IC128 CS1terminal.
Battery Backup
When Power goes down, MRSTN signal changes the level lower than 2/5 VBB before VBB reaches at 4V. When Power goes up,MRSTN signal changes the level higher than 4/5 VBB after VBB reaches at 4V. With this MRSTN signal, a certain switch over(operation mode and stand-by mode) is guaranteed. In order to guarantee the checking time function of IC128 in stand-bymode, more than 2V voltage should be added to VBB.This guaranteed voltage is supplied by the lithium battery.

D(0-1) is 2 bit/frame HDLC datachannel. B1 (7-0 ), B2 (7-0) are received and sent out in an 8 bit PCM data by MSB first individually.
DPT Frame Format
The serial port handles bit oriented protocol structure and formats the data as per the packet switching protocol defined in theX.25 (level 2) recommendations of the CCITT. It transmits and receives the packeted data (information or control)serially asshown in Figure 1.

KX-TVP50CE / KX-TVP52CE
DPT Data Packet Format
Flag:
The flag is a unique pattern of 8 bits (01111110) which defines the frame boundary. The transmit section generates the flagsand automatically appends them to the frame to be transmitted. The receive section searches the incoming packets for flagson a bit-by-bit basis and establishes frame synchronization. The flags are used only to identify and synchronize the receivedframe.
Data:
The data field refers to the Address, Control and Information fields defined in the CCITT recommendations. A valid frameshould have a data field of at least 16 bits.
Frame Check Sequence (FCS):
The 16 bits following the data field are the frame check sequence bits. The generator polynomial is:G(x) = x16 + x12 + x5 + 1The transmitter calculates the FCS on all bits of the data field and transmits after the data field and before the end flag. The
receiver performs a similar computation on all bits of the received data and FCS fields. The result is compared with FOB8Hex.If it matches, the received data is assumed to be error free.
Zero Insertion and Deletion:
The Protocol Controller, while sending either data or the 16 bits FCS, checks the transmission on a bit-by-bit basis and insertsa ZERO after every sequence of five contiguous ONEs (including the last five bits of FCS). This ensures that the flag sequenceis not simulated. Similarly, the receiver examines the incoming frame content and discards any ZERO directly following the fivecontinuous ONEs.In the serial port, the formatted data packets are shifted in/out serially at a rate equal to the clock frequency on 2MHz. The
LDVD output is transmitted on the rising edge and the receiver samples the LUVD input on the falling edge of the clock. TheCENN controls have effect only after the current bit in the packet is transmitted/received.

DPT Interface System Diagram
8.2.13. DPT Interface Operation
The DPT interface uses the H-L lines to transmit and receive the 2B+D signals compliant with the CCITX.25 protocol, i.e. thevoice data (2B) and control data (D) from 2 lines, to and from the KME TD Series PBX. The H-L signal isolated by thetransformer is separated into transmission and reception signals, then input to gate array IC125. This gate array separates theCCITX.25 protocol-compliant data into 4 serial signal channels: Cch, Dch, B1ch, and B2ch. When transmission is performed,protocol processing such as 0-insertion is performed. Cch indicates transmission start from the PBX, and reception of Cch bythe CPU as an interrupt signal initiates the communication controller of the CPU, and transmission start to the PBX occurs. Dchis for transmission and reception of PBX voice mail control data. B1 channel is for Ch1 and B2 channel is for Ch2 voice serialdata, input directly from the gate array to the DSP.
8.2.14. Gate Array Function
The gate array that controls the DPT communication is configured as follows.

B Channel Serial Loop Back Function
2 MHz clock output mode specification (Can select constant output or output only for valid data.)
Four Channel (C+D+B1+B2) Pulse Output (Active HI)
3. DR[1:0], DX[1:0], CK512K
This is the DPT Layer-1 Interface. DR[1:0] is reception input, DX[1:0] is transmission output. Layer 1 is the transfer means forthe AMI-encoded Ping-Pong format. It receives the "SYNC/MAM/C/D/B1/B2/P" data in the first half at 125 µs/frame, thentransmits "SYNC/MAM/C/D/B1/B2/P" one bit-time after receiving the P data. One bit-time is 512 KHz.After P data transmission,there is an idle period of 7 bit-time.
AMI encoding is performed based on the rules shown at the left. 1 bit data is converted into 2 bit AMI digital code with 3 valueson line (+5 V, 0 V, -5 V). For "0", the AMI encode value has two values, 2´b01 or 2´b10, so in order to encode two "0" insuccession, the previous encode value must be inverted for the next value.
Example:
0-0-0-0 → 2´b01-2´b10-2´b01-2´b100-1-0-1 → 2´b01-2´b11-2´b10-2´b11
Each field is as follows.
SYNC: This is a 5 bit continuous "00000" pattern, used in reception clock extraction by PLL.
MAM: This is a 3 bit "000" pattern (2´b01-2´b01-2´b10) contravening the AMI encoding rules, used for header detection of
57
KX-TVP50CE / KX-TVP52CE
the reception frame.
C/D: This is valid data of the C channel (1 bit) and D channel (2 bits).
B1/B2: B1/B2 is valid data of two B channels (each 8 bits). The TD Series PBX inverts the polarity of the DPT I/O B1/B2channel data, so the Layer 1 transmission/reception part also inverts the polarity of the B1/B2 channel data.
P: This is parity data. This parity overlaps the bits to maintain direct current balance.
4. SR0, SR1, SX0, CK2M, EP3, EP2, EP1, EP0
This is a 2 MBPS interface. SR[1:0] is the input stream of data transmitted to DPT Layer 1, and SX0 is the output stream of datareceived from Layer 1. These are synchronized with CK2M (basic 2.048 MHz TX/RX clock) output. The CK2M can be set to thepower saving mode which is active only when valid data is output, or the constant output mode.EP[0:3] is a TX/RX enable pulse output for C/D/B1/B2 data. The output timing of EP[2:3] for the B channel has 2 modes, theCODEC direct mode and the DATA communication mode. EP[2:3] is changed by the rising edge of CK2M in the CODEC mode,and in the DATA mode it changes 1/4 clock earlier (intermediate between the CK2M falling edge and rising edge). The EP cycleis 125 µsec. The device enabled at EP2(B1) is connected to SR1, and the device enabled at EP3(B2) is connected to SR0. SX0is common.

8.6. APT INTERFACE CIRCUIT EXPLANATIONThe APT interface uses 4 lines, H-L and T-R, for efficient connection with the analog PBX (TA series). The voice signal andDTMF signal use T-R for transmission/reception using analog format. H-L is used for voice mail, and transmission/reception ofPBX status information. The PBX connection protocol for H-L signals is original to KME, using CPU parallel I/O. H-Lcommunication for KX-TA308/KX-TA616 and KX-TVP50 provides data communication during 4 mS per 1 channel in one shotper 64 mS. During this period of 4 mS, 19 pulse signals are output from the voice mail to the PBX, including the start bit, data,parity, and stop bit. In contrast, the PBX returns 44 pulses, including the start bit, data, parity, and stop bit, thus establishingtransmission and reception.

8.10. AMPLIFIER GAIN SETTINGAmplifier Gain Setting
The gain settings for the analog voice interface are shown below. The input side passes through the speech transformer, andafter echo cancel occurs at the balance network and differential amp, the signal passes through a one-step amp and is inputto the CODEC. After the output is amplified at a one-step amp, it is output to the line interface.
Line Interface
The line interface is used as the voice recording playback interface when APT integration or SLT integration is used. Thesignal input from T-R passes through the surge absorber, Hook control circuit and the speech transformer, then is dividedinto the input and output systems at the 2 line-4 line conversion circuit before being connected to the voice CODEC.

8.11. DSPDSP
The HOST communication port is a 16-bit bi-directional register.The D6571F will access this register internally by one 16-bit wide access. The HOST accesses this register via the 8-bit bus intwo accesses: first low byte then high byte. After the HOST writes a command to the High byte of this register the D6571Faccepts this command.When the D6571F writes a status word to the communication register it sets the ACK pin low which is connected to the OSTfor indication. The HOST can use this pin as an interrupt or poll this signal periodically. When the HOST reads the high byteof this register the DSP sets the ACK bit high. The choice of high/low byte for the HOST will be made by the HI/LO pin. TheHOST should read the low byte of the status word first, then the high byte.

8.11.2. DSP Control
This unit uses a recording playback IC (D6571F) for the voice mail telephone produced by the DSPG company. It performsvoice data compression and expansion, generation and reception of DTMF signals, AGC, VOX detection , CPT detection, andvolume control. In order to provide 2-channel real time operation, memory management of voice data from the DSP isperformed by the HOST CPU.
8.11.2.1. Host Interface
The HOST CPU port of the DSP is a 16 bit bi-directional communication register. Although the DSP IC accesses this registerinternally by 16-bit wide access, the HOST CPU accesses this register via the 8 bit bus in two accesses, the low byte first, thenthe high byte. After the HOST writes a command to this high byte, the DSP IC accepts the command. After the DSP IC writesa status word to the communication register, the ACK pin is set low. When the HOST CPU has read the high byte of thisregister, the DSP sets the ACK bit high. Selection of the high/low byte for the HOST is made by the HI/LO pin. The HOST CPUfirst reads the low byte of the status word, then the high byte. Event generation from the DSP IC generates ACKn signals to theHOST CPU, and the HOST CPU inputs this signal as a Level 4 interrupt signal. The interrupt priority order is highest startingwith Ch1, then Ch2.

This logic detects temporary disconnection of the DC loop current on the telephone line during off hook conditions. The DC loopcurrent flows through T → D281 → Q282 → Q281 → R283 → PC281 - 1 → PC281 - 2 → D281 → R. When the DC loop is ON,photocoupler PC281 pin 4 - 3 is ON and CDET signal drives to low. When the DC loop is OFF, photocoupler PC281 pin 4 - 3is OFF and CDET signal drives to high.

8.11.5. Hook Control
Fig. 4-32. Hook Control
This logic controls the DC loop ON/OFF of the SLT interface. When at the ON hook condition, a PLUS signal is driven to High Levelby the Co line control Port on IC101. In this condition, photocoupler PC282 pin 4 - 3 is ON and Q282 is turned OFF. When at theOFF Hook condition, a PLUS signal is driven to low level and Q282 is turned on. As a result, the DC current flows through thefollowing path.
DC loop path: T → L283 → L281 → L285 → D281 → Q282 → Q281 → R283 → PC281 → D281→ R286 → L286 → L282 → J283→ L284 → R

This logic allows you to receive the DPT reception data from the PBX. The DPT reception data flows through HA → L289 → L291→ L287 → D291 → T292 (8 - 7) → C291→ R291 → T292 (6 - 5) → D291 → L288 → L292 → L290 → LA.
8.11.8. DPT Line Tranceiver
Fig. 4-35. DPT Line Tranceiver
This logic allows you to transmit the DPT transmission data to the PBX.
The DPT transmission signals flows as follows.
TXA = IC125 - 40 → R393 → (R265, C263) → Base of Q261.
TXB = IC125 - 41 → R394 → (R266, C264) → Base of Q262.
If IC125 drives TXA (TXB) to low level, Q261 (Q262) is turned ON and the loop current flows through as follows.
+5VA → Q261 (E - C) → (R261, C261) → T292A (3 - 4) → R204 → AG
+5VA → Q262 (E - C) → (R262, C262) → T292A (2 - 1) → AG
This loop current transition generates the DPT transmission data between T292A - 8 pin and T292A - 5 pin. As a result, T292Adrives the HA - LA line corresponding with TXA/TXB.

9 CIRCUIT OPERATIONS (POWER SUPPLY BOARD)Block Diagram
9.1. Circuit Operations 1. INPUT CIRCUITS
The AC input voltage passes through the fuse F501, the line filter L501 and the rush current suppressing power thermistorTH501, and then is applied to the rectifier diode D501.
The rectifier voltage of the AC input voltage is applied to C507.
When the AC input is 240VAC, the C507 voltage is about 330VDC.
2. Ringing Choke Converter
· Self-oscillation
By the C507 voltage, the starting current is sent into the base of Q501 via R505 and R506, and then Q501 turns on for amoment. When Q501 turns on, the C507 voltage is applied to between the primary winding 6-8 pin of T501, the base drivingvoltage of Q501 is generated in between the base winding 2-3 pin and then Q501 turns on without fail. After that, whenreached the saturation value of the collector current corresponding to the value of the base current controlled by the
79
KX-TVP50CE / KX-TVP52CE
limiting resistance R512, R513 and the control transistor Q502, Q501 turns off for a moment. When Q501 turns off, theflyback reverse voltage is generated in between the primary winding 6-8 pin of T501 and between the base winding 2-3 pin,and then Q501 turns off without fail.
By repeating the above-mentioned steps, this Ringing Choke Converter is self-rectangular-wave-oscillated. The oscillationfrequency is 90 kHz. (at 240VAC input)
· Voltage Conversion
During the self-oscillation, when Q501 is on, the rectangular waveform as the C507 voltage is the peak voltage is appliedto between the primary winding 6-8 pin of T501, converted to the appointed voltage, transferred to between the 5.5V winding(13, 14)-(15, 16), between the 15V winding (13, 14)-12 and between the -5V winding (13, 14)-11 of the secondary windingand then the appointed direct-current output voltage is generated by each rectifier smoothing circuit (5.5V: D510, C520 15V:D509, C519 (-5V: D511, C521).
· Output Voltage Stabilization
To stabilize the 5.5V output against the fluctuation of the input voltage and the load current, the shunt regulator IC503 isused for error detection and feedback. When the R-terminal voltage of IC503 changes, the K-terminal voltage changescorrespondingly and the currents of the photo-coupler PC501, the control transistor Q502 and the main transistor Q501change. As a result, the 5.5V output voltage is stabilized. The 15V output and the -5V output are stabilized by the three-terminal regulator IC501 and IC502.
3. Primary Overcurrent Protective Circuit
To prevent the overcurrent due to such as an output short circuit from damaging the main transistor Q501, the collector currentof Q501 is detected at R507. When it becomes a certain current and over, Q502 turns on, the voltage between B-E of Q501is decreased and the collector current is limited momentarily.
Moreover, against a long-period overcurrent, to prevent the on width of Q501 from spreading over a certain one; when the onwidth of the voltage between the base winding 2-3 pin of T501 becomes a certain value that is determined by the time constantof R511 and C512, Q502 turns on, the on width of Q501 is reduced, the output voltage is folded back to the 0V, the collectorcurrent is decreased, and therefore the Q501 is protected.
These primary overcurrent protective circuits work well against the short circuit of 5.5V output and 15V output whose power ofthe output short circuit is big.
Against the output short circuit of the 15V and -5V output, the overcurrent protective function of the three-terminal regulatorIC501 and IC502 itself works and the short-circuit current is limited to a certain value or under.
4. Output Overvoltage Protective Circuit
This is the function to prevent the digital circuit IC from damage when an overvoltage is generated at the output due to the shuntregulator IC503 failure, etc. The 5.5V/15V output is monitored by D512/D515. When the voltage that is the appointed value(5.5V: 6.8V 15V: 31V) and over is generated, D512 or D515 is conducted, SCR501 turns on, and the 5.5V output and the 15Voutput are in the short-circuit mode. At this time, the primary overcurrent protective circuit described at (3) works and preventsthe overcurrent damage of the main transistor Q501.
