1 ABOUT LEAD FREE SOLDER (PbF: Pb free)

Note:

In the information below, Pb, the symbol for lead in the periodic table of elements, will refer to standard solder or solder that contains lead.

We will use PbF solder when discussing the lead free solder used in our manufacturing process which is made from Tin, (Sn), Silver, (Ag), and Copper, (Cu).

This model, and others like it, manufactured using lead free solder will have PbF stamped on the PCB. For service and repair work we suggest using the same type of solder although, with some precautions, standard Pb solder can also be used.

Caution

• PbF solder has a melting point that is 50^ 70^ F, ( 30^ 40^ C) higher than Pb solder. Please use a soldering iron with temperature control and adjust it to 700^ ± 20^ F, ( 370^ ± 10^ C). In case of using high temperature soldering iron, please be careful not to heat too long.
• PbF solder will tend to splash if it is heated much higher than its melting point, approximately 1100^ , (600^) .
• If you must use Pb solder on a PCB manufactured using PbF solder, remove as much of the original PbF solder as possible and be sure that any remaining is melted prior to applying the Pb solder.
• When applying PbF solder to double layered boards, please check the component side for excess which may flow onto the opposite side (See figure, below).

1.1. SUGGESTED PbF SOLDER

There are several types of PbF solder available commercially. While this product is manufactured using Tin, Silver, and Copper, (Sn+Ag+Cu), you can also use Tin and Copper, (Sn+Cu), or Tin, Zinc, and Bismuth, (Sn+Zn+Bi). Please check the manufacturer's specific instructions for the melting points of their products and any precautions for using their product with other materials.

The following lead free (PbF) solder wire sizes are recommended for service of this product: 0.3mm, 0.6mm and 1.0mm.

2 FOR SERVICE TECHNICIANS

ICs and LSIs are vulnerable to static electricity.

When repairing, the following precautions will help prevent recurring malfunctions.

1. Cover the plastic parts boxes with aluminum foil.
2. Ground the soldering irons.
3. Use a conductive mat on the worktable.
4. Do not touch IC or LSI pins with bare fingers.

3 CAUTION

3.1. SAFETY PRECAUTIONS

1. Before servicing, unplug the power cord to prevent an electric shock.
2. When replacing parts, use only the manufacturer's recommended components for safety.
3. Check the condition of the power cord. Replace if wear or damage is evident.

4. After servicing, be sure to restore the lead dress, insulation barriers, insulation papers, shields, etc.

5. Before returning the serviced equipment to the customer, be sure to perform the following insulation resistance test to prevent the customer from being exposed to shock hazards.

1. Unplug the power cord and short the two prongs of the plug with a jumper wire.
2. Turn on the power switch.
3. Measure the resistance value with ohmmeter between the jumpers AC plug and each exposed metal cabinet part, such as screw threads, control shafts, handle brackets, etc.

Note:

Some exposed parts may be isolated from the chassis by design. These will read infinity.

1. If the measurement is outside the specified limits, there is a possibility of shock hazard. The equipment should be repaired and rechecked before it is returned to the customer.

Resistance = more than 1MΩ (at DC 500 V)

3.3. BATTERY CAUTION

1. Danger of explosion if battery is incorrectly replaced. Replace only with the same or equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's Instructions.
2. The lithium battery is a critical component (type No.CR23541). Please observe for the proper polarity and the exact location when replacing it and soldering the replacement lithium battery in.

3.4. CAUTION

The power socket wall outlet should be located near this equipment and be easily accessible.

11.2. CO INTERFACE CIRCUIT

11.2.1. Composition

This is composed of the following circuit:

1) Bell signal detection
2) DC loop formation circuit
3) Pulse dial transmission circuit
4) CALL ID interface circuit
5) COL bidirectional amplifier circuit

1) Bell signal detection

When CO line is idle, photo coupler PC1, PC2 are OFF.

When there is an incoming signal from CO line, the current flows PC1 as in the following way.

Tip → L1 → R2 → PC1(1-2) → C3 → T2 → R5 → L1 → Ring: This cause pin4 of PC1 to change the level from High to low. Ring → L1 → R5 → T2 → C3 → PC2(1-2) → R2 → L1 → Tip: This cause pin4 of PC2 to change the level from High to low.

2) DC loop formation circuit

In the off hook status, PC5 is ON.

DC loop path:

Tip→L1→D1→D2→D3→Q10(E-C)→Q1(C-E)→R9→R8→D3→L1→Ring

At this time, the output of the photo coupler PC1 changes level from High to low.

Ring→L1→D3→R8→R9→Q1(E-C)→Q10(C-E)→D3→D2→D1→L1→Tip

At this time, the output of the photo coupler PC2 changes level from High to low.

Afterwards, G/A monitor this change (low level to high level). If the high level continues for a specified time set by system data programming. G/A assumes that CO line has become On hook status. And the CO line circuits is restored to the idle status.

3) Pulse dial transmission circuit

When the Off hook status, pulse dial transmission is executed by alternating On hook and Off hook. The status of On hook or Off hook is controlled by the switching transistor Q10.

4) CALL ID interface circuit

It is insulated by the transformer in a COL circuit, and the call ID signal inputted from outside line is transmitted to a CALLID option card.

The flow of a CALLID signal

$$ \text { Tip } \rightarrow \text { L1 } \rightarrow \text { R2 } \rightarrow \text { PC1(1 - 2) } \rightarrow \text { C3 } \rightarrow \text { T2 } \rightarrow \text { R5 } \rightarrow \text { L1 } \rightarrow \text { Ring } $$

$$ \text { Ring } \rightarrow \text { L1 } \rightarrow \text { R5 } \rightarrow \text { T2 } \rightarrow \text { C3 } \rightarrow \text { PC2(1 - 2) } \rightarrow \text { R2 } \rightarrow \text { L1 } \rightarrow \text { Tip } $$

5) COL Bidirectional Amplifier circuit

This circuit consists of bidirectional amplifier function for communication between the extensions and COL, returns loss compensation for conference, shunt function and mute function.

(Composition)

For transmitting signals from the extensions to COL, this circuit consists of R34, R35, R26, R27, R18, R29, C14, C15, C10, C16 and the operational amplifier (IC1).

For transmitting signals from the COL to extensions, this circuit consists of R24, R25, R31, R28, R37, R30, C12, C13, C17, C18, and the operational amplifier (IC1).

COL side-tone suppression circuit which includes a balanced network BN1 consists of R22 R23, C11 and R16, R17, R20, R21.

EXT side-tone suppression circuit which includes a balanced network BN2 consists of R41, R42 and R40, R43, R38, R39.

Also extension side-tone suppression circuit which includes a balanced network BN3 consists of R45, R46 for supplementing side-tone suppression during the conference communication.

The analog switch (IC2) is used for the following:

(1) Conference (Pin 6, 8 and 9)

(2) Shunt (Pin 12, 10 and 11)

(3) Mute (Pin 13, 1 and 2)

1) Conference switch

Normally, pin 6 of the analog switch IC2 is low level, but during conferences, this pin becomes high level. Because, during conferences, it should compensate the return loss by connecting the balance network BN2 and the balance network BN3 in parallel.

2) Mute switch

The mute switch consists of pin 13, 1 and 2 of the analog switch(IC2). This switch has the following functions.

a) When a dial signal (DP) is sent to the COL, signals from the extensions are blocked.
b) When the hold on music is sent to the COL, signals from the extensions are blocked.
c) When the COL interface circuit is in the idle state, oscillation of COL bidirectional amplifier is inhibited. When pin 13 of IC2 changes to low level, the interval between pins 1 and 2 of the analog switch turns off, and signals are blocked.

3) Shunt switch

The shunt switch consists of pin 12, 10 and 11 of analog switch IC2. It is used to prevent the pulse dialing signal which is transmitted to the extensions. When pin 12 of IC2 changes to high from low, the analog switch becomes ON (the interval between pin 10 and 11), and GAIN of the COL cross point operational amplifier becomes zero.

	Shunt SW Mute SW Conference SW
pin no. of analog switch 12 13 6
No connection (idle) H (on) L (off)	L (off)
Two party call	L (off) H (on) L (off)
Conference	L (off) H (on)	H (on)
Hold on music transmission	L (off) H (on) L (off)

11.4. INTERCOM CIRCUIT

11.4.1. INTERCOM CIRCUIT

1) Composition

This is composed of the following circuits:

a) +15V power source for the extension telephones
b) Hook detect for SLT and pulse dialing detect
c) Bell ring trip section

2) Circuit operation

a) Power supply to the telephone

With the telephone off hook, a DC loop is formed, and current is supplied to the telephone. This circuit is limited to about 30mA by Q200, Q202, R202, R204 and Q201, Q203, R203, R205.

b) Hook detect for SLT and pulse dialing detect

When the telephone handset is taken off, DC loop is formed and the collector of U200 3,6 pin change to L from H.

The ASIC detects the off hook condition.

When the handset is replaced back on hook, the DC loop is interrupted and collector of U200 3,6 pin change to H from L and EXT Pulse dialing is input either in the on hook or off hook condition, and the break number (on hook condition) is counted and read as the dial number.

c) Bell ringing trip section

When the telephone is a signal line telephone, extension calling is executed by means of a ringing signal. When the ringing signal is supplied, RL201 turns ON and the current flows are as follows:

Bell transformer → ringing signal line → RL201 → telephone → R206 → -15V → Bell transformer

11.5. POWER FAILURE THROUGH CALL SWITCHING CIRCUIT

11.5.1. Circuit operation

If an AC power failure lasts longer than one second (momentary power failure), the COL is directly connected to the extension.

The COL1 will be connected with EXT101.

When power failure, RL200 switches from EXT-line to CO [T/R].

*In case of KX-TEM824, and the COL4 will be connected with EXT109.

*In case of KX-TE82480, and the CO7 will be connected with EXT117.

11.6. DATA COMMUNICATION CIRCUIT

11.6.1. Composition

This circuit is composed of the ASIC and the data communication interface circuits for the ICM circuit.

11.6.2. Circuit Operation

1) Data Communication of ASIC

The APT I/f module is built into the CPU. It is for the APT communication of one block (8ch) and has the module of three blocks (24ch) at maximum.

Selection signal of 3 bits to select 1ch out of 8chs is common to each block.

The APT I/f module switches the communication point every 4ms in the ports 1-8/9-16/17-24 of the extension as follows:

101→#102→#103→#104.....→#108→#101.....,

109→#110→#111→#112.....→#116→#109.....,

117→#118→#119→#120.....→#124→#117.....,

In the case where the extension is not connected with the APT, it is recognized as an SLT connection and a dummy communication is performed.

11.13. USB INTERFACE CIRCUIT

This unit have one USB port for using PC programming. ASIC have USB 1.1 controller inside, so this unit make up USB interface only ASIC and USB connector.

11.14. OGM INTERFACE CIRCUIT

The TES/TEM824 model incorporates the functions of OGM, CNG and DTMF detection. At the OGM recording, it changes the analog sound in the DSP of the ASIC into a digital signal of 16bits by A/D conversion. Then, the data is compressed (encoded) and stored in a 4M serial flash. Conversely, when being recovered the data stored in the 4M serial flash are decompressed to 16-bit digital data, and then reproduced as an analog sound after the D/A conversion. The recording/reproducing is achieved by connecting the path from external line through the cross point to the ASIC. The waveform coding method used at the recording/reproducing stage is the LD-ADPCM method. The DSP compresses the sound and stores the 4M serial flash using the memory management software in the DSP. The unit has the recording/reproducing function of 1CH as an initial mounting. The recording time of the OGM is three minutes at maximum.

Also, the CNG and DTMF detection are the functions operated in conjunction with the OGM and realized by the DSP in the ASIC.

15 HOW TO REPLACE A FLAT PACKAGE IC

Even if you do not have the special tools (for example, a spot heater) to remove the Flat IC, with some solder (large amount), a soldering iron and a cutter knife, you can easily remove the ICs that have more than 100 pins.

15.1. PREPARATION

• PbF (: Pb free) Solder
• Soldering Iron

Tip Temperature of 700^ F ± 20^ F ( 370^ C ± 10^ C)

Note: We recommend a 30 to 40 Watt soldering iron. An expert may be able to use a 60 to 80 Watt iron where someone with less experience could overheat and damage the PCB foil.

• Flux

Recommended Flux: Specific Gravity → 0.82.

Type → RMA (lower residue, non-cleaning type)

Note: See ABOUT LEAD FREE SOLDER (PbF: Pb free) (P.5).

15.2. REMOVAL PROCEDURE

1. Put plenty of solder on the IC pins so that the pins can be completely covered.

Note:

If the IC pins are not soldered enough, you may give pressure to the P.C. board when cutting the pins with a cutter.

1. Make a few cuts into the joint (between the IC and its pins) they are heated, first and then cut off the pins thoroughly.

1. While the solder melts, remove it together with the IC pins.

When you attach a new IC to the board, remove all solder left on the land with some tools like a soldering wire. If some

solder is left at the joint on the board, the new IC will not be attached properly.

15.3. INSTALLATION PROCEDURE

1. Tack the flat pack IC to the PCB by temporarily soldering two diagonally opposite pins in the correct positions on the PCB.

Pure electrical circuit lines without any symbols

● - - - - - - Temporary soldering point.

Be certain each pin is located over the correct pad on the PCB.

1. Apply flux to all of the pins on the IC.

Flux

1. Being careful to not unsolder the tack points, slide the soldering iron along the tips of the pins while feeding enough solder to the tip so that it flows under the pins as

15.4. REMOVING SOLDER FROM BETWEEN PINS

1. Add a small amount of solder to the bridged pins.
2. With a hot iron, use a sweeping motion along the flat part of the pin to draw the solder from between the adjacent pads.

23.4. EXPLANATION OF BLOCK DIAGRAM/CIRCUIT OPERATIONS

23.4.1. OPTION CARD (KX-TE82461X)

23.4.1.1.

This doorphone/door opener card is composed of the control interface with KX-TES824/KX-TEM824 and four doorphone interfaces and four dooropener interfaces section.

1) Doorphone section

This card has four doorphone interfaces, but this system has only two door phone intercom paths.

Therefore, this card has a programmable SW to connect either DOORPHONE1 or DOORPHONE2.

For example: When the DOORPHONE1 is used, the DOORPHONE2 hears a busy tone. This is repeated for Doorphone 3 and 4.

This doorphone intercom path is composed of the send amplifier and receive amplifier circuits.

The interfaces have the doorphone connect detection circuit and the doorphone hook detection circuit.

2)

This doorphone/dooropener card has four dooropener interfaces. These interfaces are used for the dooropener SW (DC 30/AC 250 5A).

It is composed of 3 C-MOS IC's. (8 x 16 matrix: 1pce 4 x 8 matrix:1pce, 8 x 8 matrix:1pce)

24.4.1.2. Intercom Circuit

This is the interface circuit of the single line telephone, and it is composed of 8 intercom circuit. (ICM17-24)

24.4.1.3. DTMF Receiver Circuit

The circuit which receives the Dial Tone Multi Frequency by which extension dispatch is carried out with the DTMF receiver connected to the crossing point.

24.4.1.4. INT CALLID Circuit

FSK/Dial Tone Multi Frequency generated by DSP in ASIC are connected even to a crossing point through AMP.

The circuit which sends out a CALLID signal to the telephone connected to an extension by connecting the line of INT-CALL-ID with arbitrary extensions.

24.4.2. Circuit Operation

24.4.2.1. Cross Point Switch Circuit

The cross point circuit composed of three cross point switch IC's. (IC701:8X16, IC702:8X8, IC703:4X8)

1) Cross Point Switch IC Operation

The cross point SW (IC701) contains a 8X16 array of cross point switches along with a 7 to 128 line decoder and latch circuits. Any one of the 128 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW (IC702) contains a 8X8 array of cross point switches along with a 6 to 64 line decoder and latch circuits. Any one of the 64 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW's (IC703) contain 4X8 array of cross point switches along with a 5 to 32 line decoder and latch circuits. Any one of the 32 switches can be addressed by selecting appropriate five address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

24.4.3. Intercom Circuit

1) Composition

This is composed of the following circuits:

a) +15V power source for the extension telephones
b) Hook detect for SLT and pulse dialing detect
c) Bell ring trip section

2) Circuit operation

a) Power supply to the telephone

With the telephone off hook, a DC loop is formed, and current is supplied to the telephone. This circuit is limited to about 30mA by Q200, Q202, R202, R204 and Q201, Q203, R203, R205.

b) Hook detect for SLT and pulse dialing detect

When the telephone handset is taken off, DC loop is formed and the collector of U200 3,6 pin change to L from H.

the ASIC detects the off hook condition.

When the handset is replaced back on hook, the DC loop is interrupted and collector of U200 3,6 pin change to H from L and EXT Pulse dialing is input either in the on hook or off hook condition, and the break number (on hook condition) is counted and read as the dial number.

c) Bell ringing trip section

When the telephone is a signal line telephone, extension calling is executed by means of a ringing signal. When the ringing signal is supplied, RL201 turns ON and the current flows are as follows:

Bell transformer → ringing signal line → RL201 → telephone → R206 → -15V → Bell transformer

24.4.4. DTMF Receiver Circuit

24.4.4.1. Composition

The DTMF receiver circuit is composed of two DTMF receivers.

IC704 and IC705 are used for the DTMF receivers from SLT connected to the extension.

The DTMF signal is the 4bit parallel data and read by ASIC.

*In case of KX-TEM824, the system have two more DTMF receiver which are in KX-TE82483.

24.4.5. INT CALLID Interface Circuit

By using the DSP built into the ASIC, it is possible to produce CALLID signal and send it through the cross point to each extension. The CALLID signal can be switched between FSK and DTMF. There are three sources of the extension CALL ID in the system.

It is composed of 3 C-MOS IC's. (8 x 16 matrix: 1pce 4 x 8 matrix:1pce, 8 x 8 matrix:1pce)

25.4.1.3. Intercom Circuit

This is the interface circuit of the single line telephone, and it is composed of 8 intercom circuit. (ICM17-24)

25.4.1.4. Power Failure Through Call Switching Circuit

This card has one power failure transfer circuit. (CO7-EXT117)

25.4.1.5. DTMF Receiver Circuit

The circuit which receives the Dial Tone Multi Frequency by which extension dispatch is carried out with the DTMF receiver connected to the crossing point.

25.4.1.6. INT CALLID Circuit

FSK/Dial Tone Multi Frequency generated by DSP in ASIC are connected even to a crossing point through AMP.

The circuit which sends out a CALLID signal to the telephone connected to an extension by connecting the line of INT-CALL-ID with arbitrary extensions.

This is composed of the following circuit:

1) Bell signal detection
2) DC loop formation circuit
3) Pulse dial transmission circuit
4) CALL ID interface circuit
5) COL bidirectional amplifier circuit

1) Bell signal detection

When CO line is idle, photo coupler PC1, PC2 are OFF.

When there is an incoming signal from CO line, the current flows PC1 as in the following way.

Tip → L1 → R2 → PC1(1-2) → C3 → T2 → R5 → L1 → Ring: This cause pin4 of PC1 to change the level from High to low.

Ring → L1 → R5 → T2 → C3 → PC2(1-2) → R2 → L1 → Tip: This cause pin4 of PC2 to change the level from High to low.

2) DC loop formation circuit

In the off hook status, PC5 is ON.

DC loop path:

Tip→L1→D1→D2→D3→Q10(E-C)→Q1(C-E)→R9→R8→D3→L1→Ring

At this time, the output of the photo coupler PC1 changes level from High to low.

Ring→L1→D3→R8→R9→Q1(E-C)→Q10(C-E)→D3→D2→D1→L1→Tip

At this time, the output of the photo coupler PC2 changes level from High to low.

Afterwards, G/A monitor this change (low level to high level). If the high level continues for a specified time set by system data programming. G/A assumes that CO line has become On hook status. And the CO line circuits is restored to the idle status.

3) Pulse dial transmission circuit

When the Off hook status, pulse dial transmission is executed by alternating On hook and Off hook. The status of On hook or Off hook is controlled by the switching transistor Q10.

4) CALL ID interface circuit

It is insulated by the transformer in a COL circuit, and the call ID signal inputted from outside line is transmitted to a CALLID option card.

The flow of a CALLID signal

$$ \text { Tip } \rightarrow \text { L1 } \rightarrow \text { R2 } \rightarrow \text { PC1(1 - 2) } \rightarrow \text { C3 } \rightarrow \text { T2 } \rightarrow \text { R5 } \rightarrow \text { L1 } \rightarrow \text { Ring } $$

$$ \text { Ring } \rightarrow \text { L1 } \rightarrow \text { R5 } \rightarrow \text { T2 } \rightarrow \text { C3 } \rightarrow \text { PC2(1 - 2) } \rightarrow \text { R2 } \rightarrow \text { L1 } \rightarrow \text { Tip } $$

5) COL Bidirectional Amplifier circuit

This circuit consists of bidirectional amplifier function for communication between the extensions and COL, returns loss compensation for conference, shunt function and mute function.

(Composition)

For transmitting signals from the extensions to COL, this circuit consists of R34, R35, R26, R27, R18, R29, C14, C15, C10, C16 and the operational amplifier (IC1).

For transmitting signals from the COL to extensions, this circuit consists of R24, R25, R31, R28, R37, R30, C12, C13, C17, C18, and the operational amplifier (IC1).

COL side-tone suppression circuit which includes a balanced network BN1 consists of R22 R23, C11 and R16, R17, R20, R21.

EXT side-tone suppression circuit which includes a balanced network BN2 consists of R41, R42 and R40, R43, R38, R39.

Also extension side-tone suppression circuit which includes a balanced network BN3 consists of R45, R46 for supplementing side-tone suppression during the conference communication.

The analog switch (IC2) is used for the following:

(1) Conference (Pin 6, 8 and 9)

(2) Shunt (Pin 12, 10 and 11)

(3) Mute (Pin 13, 1 and 2)

1) Conference switch

Normally, pin 6 of the analog switch IC2 is low level, but during conferences, this pin becomes high level. Because, during conferences, it should compensate the return loss by connecting the balance network BN2 and the balance network BN3 in parallel.

2) Mute switch

The mute switch consists of pin 13, 1 and 2 of the analog switch(IC2). This switch has the following functions.

a) When a dial signal (DP) is sent to the COL, signals from the extensions are blocked.
b) When the hold on music is sent to the COL, signals from the extensions are blocked.
c) When the COL interface circuit is in the idle state, oscillation of COL bidirectional amplifier is inhibited. When pin 13 of IC2 changes to low level, the interval between pins 1 and 2 of the analog switch turns off, and signals are blocked.

3) Shunt switch

The shunt switch consists of pin 12, 10 and 11 of analog switch IC2. It is used to prevent the pulse dialing signal which is transmitted to the extensions. When pin 12 of IC2 changes to high from low, the analog switch becomes ON (the interval between pin 10 and 11), and GAIN of the COL cross point operational amplifier becomes zero.

	Shunt SW Mute SW Conference SW
pin no. of analog switch 12 13 6
No connection (idle) H (on) L (off)	L (off)
Two party call	L (off) H (on) L (off)
Conference	L (off) H (on)	H (on)
Hold on music transmission	L (off) H (on) L (off)

Condition of COL interface amplifier circuit and analog switches.

25.5.2. Cross Point Switch Circuit

25.5.2.1. Composition

The cross point circuit composed of three cross point switch IC's. (IC701:8X16, IC702:8X8, IC703:4X8)

1) Cross Point Switch IC Operation

The cross point SW (IC701) contains a 8X16 array of cross point switches along with a 7 to 128 line decoder and latch circuits. Any one of the 128 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW (IC702) contains a 8X8 array of cross point switches along with a 6 to 64 line decoder and latch circuits. Any one of the 64 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW's (IC703) contain 4X8 array of cross point switches along with a 5 to 32 line decoder and latch circuits. Any one of the 32 switches can be addressed by selecting appropriate five address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

25.5.3. Intercom Circuit

1) Composition

This is composed of the following circuits:

a) +15V power source for the extension telephones
b) Hook detect for SLT and pulse dialing detect
c) Bell ring trip section

2) Circuit operation

a) Power supply to the telephone

With the telephone off hook, a DC loop is formed, and current is supplied to the telephone. This circuit is limited to about 30mA by Q200, Q202, R202, R204 and Q201, Q203, R203, R205.

b) Hook detect for SLT and pulse dialing detect

When the telephone handset is taken off, DC loop is formed and collector of U200 3,6 pin change to L from H.

The ASIC detects the off hook condition.

When the handset is replaced back on hook, the DC loop is interrupted and collector of U200 3,6 pin change to H from L and EXT Pulse dialing is input either in the on hook or off hook condition, and the break number (on hook condition) is counted and read as the dial number.

c) Bell ringing trip section

When the telephone is a signal line telephone, extension calling is executed by means of a ringing signal. When the ringing signal is supplied, RL201 turns ON and the current flows are as follows:

Bell transformer → ringing signal line → RL201 → telephone → R206 → -15V → Bell transformer

25.5.4. Power Failure Through Call Switching Circuit

25.5.4.1. Circuit Operation

If an AC power failure lasts longer than one second (momentary power failure), the COL is directly connected to the extension. The COL7 will be connected with EXT117.

25.5.5. DTMF Receiver Circuit

25.5.5.1. Composition

The DTMF receiver circuit is composed of two DTMF receivers.

IC704 and IC705 are used for the DTMF receivers from SLT connected to the extension.

The DTMF signal is the 4bit parallel data and read by ASIC.

26.4. EXPLANATION OF BLOCK DIAGRAM

26.4.1. Option Card (KX-TE82483X)

26.4.1.1. CO Interface Circuit

There are the interface circuits linking the CO line (CO4 -CO6) and the cross point circuit section.

26.4.1.2. Cross Point Circuit

This is a space division switching system for connecting the following:

The eight extension circuits with the eight CO,DTMF generator, DTMF receiver, INT-CALL ID,MODEM,OGM, BV, paging, music on hold, tone etc.

It is composed of 3 C-MOS IC's. (8 X 16 matrix: 1pce 4 X 8 matrix: 1pce, 8 X 8 matrix: 1pce)

26.4.1.3. Intercom Circuit

This is the interface circuit of the single line telephone, and it is composed of 8 intercom circuit. (ICM9-16)

26.4.1.4. Power Failure Through Call Switching Circuit

This card has one power failure transfer circuit. (CO4-EXT109)

26.4.1.5. DATA Communication Circuit

The APT i/f module which performs communication with a private telephone machine is built in ASIC located main unit.

26.4.1.6. DTMF Receiver Circuit

The circuit which receives the Dial Tone Multi Frequency by which extension dispatch is carried out with the DTMF receiver connected to the crossing point.

FSK/Dial Tone Multi Frequency generated by DSP in ASIC are connected even to a crossing point through AMP.

The circuit which sends out a CALLID signal to the telephone connected to an extension by connecting the line of INT-CALL-ID with arbitrary extensions.

This is composed of the following circuit:

1) Bell signal detection
2) DC loop formation circuit
3) Pulse dial transmission circuit
4) CALL ID interface circuit
5) COL bidirectional amplifier circuit

1) Bell signal detection

When CO line is idle, photo coupler PC1, PC2 are OFF.

When there is an incoming signal from CO line, the current flows PC1 as in the following way.

Tip → L1 → R2 → PC1(1-2) → C3 → T2 → R5 → L1 → Ring: This cause pin4 of PC1 to change the level from High to low.

Ring → L1 → R5 → T2 → C3 → PC2(1-2) → R2 → L1 → Tip: This cause pin4 of PC2 to change the level from High to low.

2) DC loop formation circuit

In the off hook status, PC5 is ON.

DC loop path:

Tip→L1→D1→D2→D3→Q10(E-C)→Q1(C-E)→R9→R8→D3→L1→Ring

At this time, the output of the photo coupler PC1 changes level from High to low.

Ring→L1→D3→R8→R9→Q1(E-C)→Q10(C-E)→D3→D2→D1→L1→Tip

At this time, the output of the photo coupler PC2 changes level from High to low.

Afterwards, G/A monitor this change (low level to high level). If the high level continues for a specified time set by system data programming. G/A assumes that CO line has become On hook status. And the CO line circuits is restored to the idle status.

3) Pulse dial transmission circuit

When the Off hook status, pulse dial transmission is executed by alternating On hook and Off hook. The status of On hook or Off hook is controlled by the switching transistor Q10.

4) CALL ID interface circuit

It is insulated by the transformer in a COL circuit, and the call ID signal inputted from outside line is transmitted to a CALLID option card.

The flow of a CALLID signal

$$ \text { Tip } \rightarrow \text { L1 } \rightarrow \text { R2 } \rightarrow \text { PC1(1 - 2) } \rightarrow \text { C3 } \rightarrow \text { T2 } \rightarrow \text { R5 } \rightarrow \text { L1 } \rightarrow \text { Ring } $$

$$ \text { Ring } \rightarrow \text { L1 } \rightarrow \text { R5 } \rightarrow \text { T2 } \rightarrow \text { C3 } \rightarrow \text { PC2(1 - 2) } \rightarrow \text { R2 } \rightarrow \text { L1 } \rightarrow \text { Tip } $$

5) COL Bidirectional Amplifier circuit

This circuit consists of bidirectional amplifier function for communication between the extensions and COL, returns loss compensation for conference, shunt function and mute function.

(Composition)

For transmitting signals from the extensions to COL, this circuit consists of R34, R35, R26, R27, R18, R29, C14, C15, C10, C16 and the operational amplifier (IC1).

For transmitting signals from the COL to extensions, this circuit consists of R24, R25, R31, R28, R37, R30, C12, C13, C17, C18, and the operational amplifier (IC1).

COL side-tone suppression circuit which includes a balanced network BN1 consists of R22 R23, C11 and R16, R17, R20, R21.

EXT side-tone suppression circuit which includes a balanced network BN2 consists of R41, R42 and R40, R43, R38, R39.

Also extension side-tone suppression circuit which includes a balanced network BN3 consists of R45, R46 for supplementing side-tone suppression during the conference communication.

The analog switch (IC2) is used for the following:

(1) Conference (Pin 6, 8 and 9)

(2) Shunt (Pin 12, 10 and 11)

(3) Mute (Pin 13, 1 and 2)

1) Conference switch

Normally, pin 6 of the analog switch IC2 is low level, but during conferences, this pin becomes high level. Because, during conferences, it should compensate the return loss by connecting the balance network BN2 and the balance network BN3 in parallel.

2) Mute switch

The mute switch consists of pin 13, 1 and 2 of the analog switch(IC2). This switch has the following functions.

a) When a dial signal (DP) is sent to the COL, signals from the extensions are blocked.
b) When the hold on music is sent to the COL, signals from the extensions are blocked.
c) When the COL interface circuit is in the idle state, oscillation of COL bidirectional amplifier is inhibited. When pin 13 of IC2 changes to low level, the interval between pins 1 and 2 of the analog switch turns off, and signals are blocked.

3) Shunt switch

The shunt switch consists of pin 12, 10 and 11 of analog switch IC2. It is used to prevent the pulse dialing signal which is transmitted to the extensions. When pin 12 of IC2 changes to high from low, the analog switch becomes ON (the interval between pin 10 and 11), and GAIN of the COL cross point operational amplifier becomes zero.

26.5.2. Cross Point Switch Circuit

26.5.2.1. Composition

The cross point circuit composed of three cross point switch IC's. (IC500:8X16, IC501:8X8, IC502:4X8)

1) Cross Point Switch IC Operation

The cross point SW (IC500) contains a 8X16 array of cross point switches along with a 7 to 128 line decoder and latch circuits. Any one of the 128 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW (IC501) contains a 8X8 array of cross point switches along with a 6 to 64 line decoder and latch circuits. Any one of the 64 switches can be addressed by selecting appropriate seven address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

The cross point SW's (IC502) contain 4X8 array of cross point switches along with a 5 to 32 line decoder and latch circuits. Any one of the 32 switches can be addressed by selecting appropriate five address bits. The selected switch can be turned on or off by applying either logical one or zero to the DATA input. Chip select allows the cross point array to be cascaded for matrix expansion.

26.5.3. Intercom Circuit

1) Composition

This is composed of the following circuits:

a) +15V power source for the extension telephones
b) Hook detect for SLT and pulse dialing detect
c) Bell ring trip section

2) Circuit operation

a) Power supply to the telephone

With the telephone off hook, a DC loop is formed, and current is supplied to the telephone. This circuit is limited to about 30mA by Q200, Q202, R202, R204 and Q201, Q203, R203, R205.

b) Hook detect for SLT and pulse dialing detect

When the telephone handset is taken off, DC loop is formed and collector of U200 3,6 pin change to L from H.

The ASIC detects the off hook condition.

When the handset is replaced back on hook, the DC loop is interrupted and collector of U200 3,6 pin change to H from L and EXT Pulse dialing is input either in the on hook or off hook condition, and the break number (on hook condition) is counted and read as the dial number.

c) Bell ringing trip section

When the telephone is a signal line telephone, extension calling is executed by means of a ringing signal. When the ringing signal is supplied, RL201 turns ON and the current flows are as follows:

Bell transformer → ringing signal line → RL201 → telephone → R206 → -15V → Bell transformer

26.5.4. Power Failure Through Call Switching Circuit

26.5.4.1. Circuit Operation

If an AC power failure lasts longer than one second (momentary power failure), the COL is directly connected to the extension. The COL4 will be connected with EXT109.

26.5.5. DATA Communication Circuit

26.5.5.1. Composition

This circuit is composed of the ASIC and the data communication interface circuits for the ICM circuit.

26.5.5.2. Circuit Operation

1) Data Communication of ASIC

The APT I/f module is built into the CPU. It is for the APT communication of one block (8ch) and has the module of three blocks (24ch) at maximum.

selection signal of 3 bits to select 1ch out of 8chs is common to each block.

The APT I/f module switches the communication point every 4ms in the ports 1-8/9-16/17-24 of the extension as follows:

$$ # 1 0 1 \rightarrow # 1 0 2 \rightarrow # 1 0 3 \rightarrow # 1 0 4 \dots \rightarrow # 1 0 8 \rightarrow # 1 0 1 \dots , $$

$$ # 1 0 9 \rightarrow # 1 1 0 \rightarrow # 1 1 1 \rightarrow # 1 1 2 \dots \rightarrow # 1 1 6 \rightarrow # 1 0 9 \dots , $$

$$ # 1 1 7 \rightarrow # 1 1 8 \rightarrow # 1 1 9 \rightarrow # 1 2 0 \dots \rightarrow # 1 2 4 \rightarrow # 1 1 7 \dots , $$

In the case where the extension is not connected with the APT, it is recognized as an SLT connection and a dummy communication is performed.

29.4.1.1. Call ID Detect Circuit

Circuit Operation

This card has three CALL ID detect circuits for support of three COL parts. If necessary to detect CALL ID on eight COLS then three KX-TE82493 cards are required to be installed in the system. If only required to detect CALL ID on three COLS, then only one KX-TE82493 card is required.

Incoming signal from COL is detected by CALL ID IC. The CALL ID data changed to serial data from parallel data (8 bit data) by FPGA. After, the 16 bit CPU detect this 8 bit data and sending the CALL ID data for PITS.
