IMPORTANT INFORMATION ABOUT LEAD FREE, (PbF), SOLDERING
If lead free solder was used in the manufacture of this product the printed circuit boards will be marked PbF, Standard laded, (Pb),
solder can be used as usual on boards without the PbF mark.
When this mark does appear please read and follow the special instructions described in this manual on the use of PbF and how
it might be permissible to use Pb solder during service and repair work.

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°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
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.

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 CIRCUIT OPERATIONS
7.1. CONTROL-SYSTEM CIRCUIT
7.1.1. CPU Peripherals
• • •
• CPU (System clock: 12.288 MHz)......IC401
Data bus: 16bit, Address bus: 23bit
• • •
• Flash ROM (512Kbyte)......IC402
Flash memory consists of two areas: boot space and administration space.
Administration program can be rewritten through downloading.
• • •
• SRAM (128Kbyte)......IC403
Used for the data buffer for CPU work area.
• • •
• Reset
Resets of an ELCOT16 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 Reset method Specification
ASIC reset ASIC reset is reset under the AND condition of reset signals (negative logic)
listed below.
Power-on reset Reset by reset IC
Hard reset from the main bus Reset by EC_RST signal
Soft reset from the main bus Released after the specified time
LPR reset Soft reset from the main bus 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)
15
KX-TDA6181X

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 enter the halt state while the contents of the register, the internal RAM, and the I/O port is
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

7.1.2. Time Slot Configuration
PCM data of an arbitrary stream, 0 - 15 (1 stream equals 128 time slots), on H.100 bus can be switched to an arbitrary local
highway (64 time slots) using a local TSW.
An example of time slot configuration of a local highway in ELCOT16 is shown below.

KX-TDA6181X

7.2. DESCRIPTION OF FUNCTIONS AND CIRCUITS
7.2.1. Dial Pulse Signal Transmission
Transmits 10pps/20pps dial pulse by a open/close action between Tip and Ring with Photo MOS relay.
The make width, break width and inter digital width for 10pps/20pps can be set respectively.
When making, 37pin (DIAL [0]) of IC6 becomes Low level, and PL2 turns ON. When breaking, 37pin (DIAL [0]) of IC6 becomes
High level, and PL2 turns OFF.
It provides the SHUNT control function for the stabilization of line power depending on the destination. Turning ON PC5 when
transmitting pulse reduces the impedance at making, and stabilizes the line power.
7.2.2. Circuit For Line Acquisition
Making 37pin (DIAL[0]) of IC6 Low level, the photo MOS relay (PL2) turns ON and the line is acquired.
It is used in common as Dial Pulse transmitting circuit.
DC Loop Path:
• • •
• Ring→L3→L2→RL1→J5→D2→PL2→Q6(C-E)→R5→R80→D2→RL1→J3→L1→L4→J7→Tip
• • •
• Tip→J7→L4→L1→J3→RL1→D2→PL2→Q6(C-E)→R5→R80→D2→J5→RL1→L2→L3→Ring
7.2.3. DTMF Signal Transmission
This transmits the DTMF signal on the highway timeslot. The different DTMF signals can be transmitted to the optional ports at the
same time.
They are transmitted to the line through CODEC.
19
KX-TDA6181X

7.2.4. Bell Signal Detection
During on-hook, transmitting the bell signal to the AC loop in the CR series circuits (C2 and R2) detects the current by Photo
Coupler (PC1,2), and it determines the presence of a bell signal. Software performs the operation for recognition and determination
of a pattern of bell signals.
Bell Loop Path:
• • •
• Ring→L3→L2→RL1→R50→PC1(1-2)→C2→R2→J9→RL1→J3→L1→L4→J7→Tip
In this path, PC1 4-pin converts from High to Low, and a bell signal is detected.
• • •
• Tip→J7→L4→L1→J3→RL1→J9→R2→C2→PC2(1-2)→R50→RL1→L2→L3→Ring
In this path, PC2 4-pin converts from High to Low, and a bell signal is detected.
7.2.5. DTMF Signal Detection
This is provided on the CALLER ID detection card (CID8) and CALLER ID/PAYTONE detection card (CID/PAY8) of the option
cards.
7.2.6. Polarity Reversal Detection
Configured by the photo couplers (PC1,PC2) which enables current detection in either the Tip →Ring or Ring →Tip directions.
(PC2 is used in common as the bell detection photo coupler). Using Software, it stores the current direction (the detected photo
coupler) of the connected trunk and adjusts the direction of the current flow detection. (the detected photo coupler changes).
When the current flows in the direction of Ring to Tip, PC1 4-pin is Low and PC2 4-pin is High.
• • •
• Ring→L3→L2→RL1→R50→PC1(1-2)→J5→D2→PL2→Q6(C-E)→R5→R80→D2→RL1→J3→L1→L4→J7→Tip
When the current direction (polarity) is reversed from Tip to Ring, PC1 4-pin turns to High and PC2 4-pin turns to Low. It recognizes
the action by changing of the current direction (the detected photo coupler changes).
• • •
• Tip→J7→L4→L1→J3→RL1→D2→PL2→Q6(C-E)→R5→R80→D2→J5→PC2(1-2)→R50→RL1→L2→L3→Ring
