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 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°F, (600°C).
• 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 manufac
turer’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.

Using Analogue Trunk Card and Extension Card
Power Failure Connection connects a specific SLT and a trunk in the event of power failure. The following analogue trunk and
extension cards can be used for Power Failure Connections:
• Analogue trunk card: ELCOT16 (4 PFT ports)
• Extension card: EMSLC16 (4 PFT ports), ESLC16 (4 PFT ports), DHLC8 (2 PFT port) and SLC8 (2 PFT port)
To 1 analogue trunk card, connect only 1 extension card.
Note:
• Power Failure Connections must be made within the same shelf.
• By programming the Hybrid IP-PBX, a trunk conversation established during power failure can be maintained even when the
power returns and the connection is switched back to the normal maintained even when the power returns and the
connection is switched back to the normal performed, the connection will be dropped when power returns.

7.1.
7.1.1.
CONTROL-SYSTEM CIRCUIT
CPU Peripherals
• CPU (System clock: 12.288 MHz)......IC601
Data bus: 16bit, Address bus: 23bit
• Flash ROM (512Kbyte)......IC602
Flash memory consists of two areas: boot space and administration space.
Administration program can be rewritten through downloading.
• SRAM (1Mbit)......IC603
Used for the data buffer for CPU work area, and PT communication.
• Reset
Resets of an ESLC16 card are roughly classified into the two kinds: ASIC reset and LPR reset.
After the release of the ASIC reset, the LPR reset is released by the soft reset from the side of the main card and the LPR
program is booted.
Type of reset
ASIC reset

Low active
Reset pulse width: 1.6 microseconds or more
• LED Operation status indicating LED (Two colors)
OFF: Fault
Red ON: Fault (RESET included)
Green ON: Normal (Line not in use)
Green Flash (60/minute): Normal (Line in use)
14
KX-TDA6174XJ / KX-TDA6174X
Orange: OUS (Because OUS needs to be controlled by EMPR, reset terminal and port control terminal are ORed to generate
OUS)
• Instantaneous power interruption operation
When instantaneous power interruption is 300msec or less, reset operation is not carried out because the voltage is retained
by the capacitor in the power supply.
After HALT from EMPR is detected at the DC power down port, CPU goes into the sleep mode by executing the instruction of
SLEEP.
At the sleep mode, the CPU/Clock enters the halt state while the contents of the register, the internal RAM, and the I/O port are
maintained.
When the instantaneous power interruption is released, HALT is negated, and CPU is recovered to the normal mode by the
detection of IRQ0=L
15
KX-TDA6174XJ / KX-TDA6174X
7.1.2.
IC14 (ASIC)
• EC bus interface
Independent bus for 16bit/8MHz two-way address data multiplex.
• CT bus interface
Supports eight 8.192MHz highways (128 time slots).
• Local TSW
Exchanges the time slots between CT bus (1024ch) and local highway (64ch).
• Local highway interface
Accommodates 2.048, 4.096, and 8.192MHz highways (Up to 64 time slots).
• Local gain control
Controls the gain of the local highway up-and-down 64ch in 1db step arbitrarily.
• CODEC interface
Can connect up to four Infineon-manufactured PEB2466, and is intended for enabling the line control.
16
KX-TDA6174XJ / KX-TDA6174X
• GPIO interface
Parallel interface that is arbitrarily programmable bidirectionally.
7.2.
CODEC FUNCTION(IC201,202,250,251)
Infineon PEB2466 CODEC is installed. The analogue features such as BN, frequency characteristic, volume level, sidetone are
configured by ASIC CODEC interface DCLK, CS, DOUT, DIN. In addition, the CODEC has an internal I/O port that supports Hook
detection, DTMF detection, BELL relay control and DIAG relay control. Also, it converts A/D to D/A, and 4-line-analogue signal to
PCM code in G.711 format.
17
KX-TDA6174XJ / KX-TDA6174X
7.3.
2W-4W CONVERSION
It converts 4W-VOX signal used in the PBX to 2W-VOX signal used in SLT, and vice versa. It consists of an operational amplifier
in the HIC and a balanced network in the CODEC. It can control the return loss of the audio data and frequency characteristics.
By modifying the CODEC program, it can match the corresponding impedance.
7.4.
DTMF SIGNAL DETECTION
Each port has its own DTMF receiver. The receiver detects the signal using IC1 for port A through D, IC2 for port E through H, IC4
for port I through L and IC6 for port M through P. The CODEC detects the DTMF data to be effective at EST terminal=H. This
information is detected in the EMPR via SAMSON, then DTMF signal is detected by EMPR reading the DTMF receiver data that
came through the SAMSON local bus.
18
KX-TDA6174XJ / KX-TDA6174X
7.5.
POWER SUPPLY
A constant-current power supply in HIC provides +30V, ring side 0V grounding to SLC. The maximum feeding current is 30mA.
7.6.
DIAL PULSE DETECTION
When a telephone initiates pulse dialing, this feature detects the pulse-dialing signal.When the telephone initiates dialing, changes
in voltage is detected by the RING terminal in HIC, and this information is transmitted to the HOOK terminal (Example: 3-pin
IC200A) as Make=L/Break=H signal. This digital signal is received by CODEC IC (Example: 35-pin IC201) and recognized as
dialing signal. Both 10pps and 20pps can be received. The dialing speed is analyzed by software.
19
KX-TDA6174XJ / KX-TDA6174X
7.7.
HOOK DETECTION
The off-hook status is detected when the telephone is off-hook. When a telephone is off-hook, change in voltage is detected by the
RING terminal in HIC, and this information is transmitted to the HOOK terminal (Example: 9-pin IC200A) as OFF-HOOK=L/ON
HOOK=H signal. This digital signal is received by CODEC IC (Example: 35-pin IC201) and recognized as off-hook signal. The offhook status is analyzed by software.
7.8.
RING TRIP FEATURE
When the BELL signal is sent out, the off-hook signal from a SLT is detected, and then it breaks the BELL relay.When the handset
of a ringing telephone is picked up, a DC loop is formed in the sequence of "Original bell signal", "Internal electrical resistance of
a telephone", "Intercom bell load resistance" (R203A-P:1KΩ), and then "Ground" (Since DC30V superimposed in the BELL signal).
As a result of this, a voltage rise occurs in Intercom bell load resistance" (R203A-P:1KΩ) in the intercom circuit, and a voltage is
placed on the 9-pin RING terminal. This change in voltage turns off the driver transistor of the BELL relay in HIC, and it breaks the
BELL relay.
20
KX-TDA6174XJ / KX-TDA6174X
7.9.
SURGE PROTECTION
ZNRs installed between T and R, and between T or R and FG protect from extraneous surge.
7.10. SELF-DIAGNOSIS
A self-diagnosis relay (RL201A) is installed in A port. In the normal operation mode, it breaks the self-diagnosis relay, and in the
self-diagnosis mode, it makes the self-diagnosis relay. In the self-diagnostic mode, A Tip-Ring is connected to the paired Tip-Ring
of the outside-line card via backboard, and self-diagnosis is feasible.The self-diagnosis of the outside-line card includes outside call
pick up, dial pulse transmission, DTMF transmission, BELL reception and CPC detection.
21
KX-TDA6174XJ / KX-TDA6174X
7.11. POWER FAILURE SWITCH FEATURE
4 out of 16 lines have switching relays (RL200A-D) installed in order to enable the outside call during a power failure. The line
connected to the outside call card will be directly connected to the CN201/202 located in forward part of the board via a 4-conductor
TEL cord. In the normal operation mode, it breaks the power failure switching relay, and during a power failure, it makes the power
failure switching relay to initiate Power failure direct connection mode.
7.12. BELL SIGNAL GENERATOR
Bell signal for ringing an SLT is generated by amplifying the 20 or 25Hz square wave provided from EMPR card to AC75Vrms
onboard. The SW power supply in the BELL circuit generates between +160V and -100V of voltage by switching the +40V from the
power source at 125KHz frequencies. The Bell signal picks up the square wave provided from EMPR via a photocoupler, and it is
transformed into SIN wave, then amplified to AC75Vrm bell signal by the amplitude between +160V and -100V of voltage (Mainly
+30Vdc) produced by SW power supply. When the Bell signal is not needed, bell signal voltage generating circuit can be turned
off by transmitting H signal from P21 port (BELL CNT) of ASIC to reduce the power consumption.

7.13. BELL SIGNAL TRANSMISSION
AC 75Vrms bell signal generated onboard is transmitted to the individual port, then control the bell ON/OFF by making a bell relay
in each port (Bell signal ON) and by breaking it (Bell signal OFF). The 16 ports do not ring simultaneously. They are divided into
4 layers to control ON/OFF. They are divided in to following 4 groups (The ports in the same group ring simultaneously.): "1, 5, 9,
13", "2, 6, 10, 14", "3, 7, 11, 15" and "4, 8, 12, 16".

POWER SUPPLY VOLTAGE GENERATOR
The input from the main power supply is in 3 voltage levels: +15V, +30V, +40V. Since the voltage levels: +15V, +5V, +3.3V, +40V,
+160V, +100V, -100V and AC 75Vrms are required onboard, voltage levels are generated onboard as written below.
A DC-DC converter that generates +3.3V and +5V from 15V input from the main power supply.It consists of a circuit that steps
down the voltage from +15V to +3.3V by the switching power supply of IC10, Q13 and L10, and a circuit that steps down the voltage
from +15V to +5V by the switching power supply of IC7, Q12 and L7.As protective circuits, IP4 that protects from +3.3V short circuit,
IP5 that protects from +5V short circuit, and an overvoltage protection that breaks IP1 by turning on FET in Q14 when a rise in
voltage of +3.3V/+5V is detected.

10 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.
10.1. PREPARATION
solder is left at the joint on the board, the new IC will not be
attached properly.
• PbF (: Pb free) Solder
10.3. INSTALLATION PROCEDURE
• Soldering Iron
1. Tack the flat pack IC to the PCB by temporarily soldering
two diagonally opposite pins in the correct positions on the
PCB.
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.3).
10.2. REMOVAL PROCEDURE
Be certain each pin is located over the
correct pad on the PCB.
1. Put plenty of solder on the IC pins so that the pins can be
completely covered.
2. Apply flux to all of the pins on the IC.
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.
3. 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
they are heated.
2. Make a few cuts into the joint (between the IC and its pins)
first and then cut off the pins thoroughly.
10.4. REMOVING SOLDER FROM
BETWEEN PINS
3. While the solder melts, remove it together with the IC 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.
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
