SECTION 3. INSTALLAT ION
3.1 INTRODUCTION
As with any sophisticated communications device, installation of the GDK-20W System requires the care and
fore-thought of a competent technician. Installation proceeds in 4 major steps:
-. Site Preparation
-. KSU Installation
-. PCB Installation
-. System Wiring
-. DECT Installation
3.2 SITE PREPARATION
General Site Considerations
The first step is to locate an acceptable site for the common equipment.(KSU, boards, etc.)
When locating a mounting site for the KSUs, the following points must be considered:
1.
2.
3.
4.
5.
The KSUs are designed for wall mounting and should not be mounted directly to a masonry or plaster board wall. It
is recommended that a ½ inch thickness plywood back-board be firmly mounted to the wall first and then the KSU.
The location must have access to 220~240 Volt AC, 50 - 60 Hz with a circuit breaker or fuse rated at 15 amps. A 3-
wire parallel blade grounded outlet should be within approximately 2 meters (6 feet).
The location must have access to a good earth ground, such as a metallic cold water pipe with no non-metallic
joints. The ground source should be located as close as possible to the system.
The system should be located in an area which is well ventilated with a recommended temperature of 20 - 26
degrees C (68 - 78.8 degrees F) and a relative humidity of 5 - 85 % (non-condensing).
The system should be located within 8 meters (25 feet) of the telephone company's termination point. Also, the
location should be within the prescribed station loop lengths for all keysets and terminals. If existing cabling is to be
employed, the location of existing cabling and conduits should be considered.
6.
The location should have adequate accessibility, space and lighting for future servicing and should consider the
need for future expansion.
7. The site should be away from radio transmitting equipment, arc-welding devices, copy machines, and other
electrical equipment capable of generating electrical interference. The system should be protected from flooding
and heavy machinery as well as excessive dust and vibration.
19
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
Back-Board Installation
A wooden backboard is recommended for all installations and must be installed when the location has masonry or
plasterboard walls. A ½ inch plywood material is sufficient for most installations. The back-board should be mounted at
a convenient height, about 1 meter above the floor, and be bolted in two number of places to distribute the weight of the
system.
Verify On-Site Equipment
Once the equipment installation site has been identified and a dedicated earth ground, and lighting and ventilation are
available, verify that all equipment required are on-site and have not been damaged during shipment. Assure there is no
shipping damage. Note that a mounting template is packed with KSU and this template will be required later in the
installation. Check that the type and quantity of boards received is correct and optional equipment are on-site.
If any equipment is damaged or missing, notify appropriate personnel to correct the situation.

GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
3.3 KSU & POWER INSTALLATION
GDK-20W system consists of KSU, some optional boards, and peripheral instruments. The exterior view of the GDK-20W
is shown in Figure 3.3.1.
Figure 3.3.1 GDK-20W Exterior View
Mounting the KSU
The KSU is a plastic frame cabinet designed for wall mounting. Employing the KSU mounting template provided with the
KSU, mark the location of the two screws to mount the KSU. Again, the KSU must not be mounted on a masonry or dry-
wall surface, in this case a wooden backboard is required, refer to paragraph [Back Board Installation]. The distance
between mounting holes is shown in Figure 3.3.2.
The KSU is mounted with two #10 or larger, 1.5 inch or longer screws. First, drill pilot holes in the two locations marked,
insert the screws and tighten leaving about 0.5 inch exposed. Hang up the KSU on the screws and tighten the KSU.

Power Installation
The Power Supply Circuit of the MBU provides power for the system boards and telephones, converting the AC Input
Voltage to appropriate DC voltages. Before installation, assure that the AC power cord is NOT plugged into the AC
INLET. The Power Supply Circuit is located on the left upper side of the MBU.
The GDK-20W Power can only operate 220~240V AC based on the connection of the cable(4-wired) by the CN22 from
transformer and the connection of the cable(2-wired) by the CN21 to transformer.

GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
KSU Grounding
The GDK-20W mains lead must be connected to a building mains supply that includes an earth connection in
conformance with current IEE requirements.
Earthling is required for user safety and to minimize EMC interference.
If does not connected mains earth, to ensure proper system operation and for safety purpose, a good earth ground is
required. A metallic COLD water pipe usually provides a reliable ground. Carefully check that the pipe does not contain
insulated joints that could isolate the ground path. If insulated joints exist, another earth ground source must be used or,
if allowed, the joints may be bridged.
A #14 AWG or larger copper wire should be used between the ground source and the connector, CN27, of the KSU. The
wire should be kept as short as possible, it is recommended that the wire be no longer than 8 meters.(about 25 feet)
23
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
3.4 PCB INSTALLATION
PCB Handling & General Installation
All boards should not be installed or removed while power applied.
Power must be turned off prior to insertion or removal of the PCB.
The system PCBs contain digital circuitry which can be damaged by exposure to excessive static electricity. When
handling PCBs, a grounded wrist strap should be used to protect the boards from static discharges. Also, use common
sense when handling the PCBs. For example, do not place a PCB in locations where heavy objects might fall on the PCB
and damage components.
To insert a PCB, hold the PCB and, with component side facing right, insert the card into the MBU’s din connector firmly
and tighten. To remove a PCB, reverse the procedure. Installation method of PCB is shown in Figure 3.4.1.

Battery Back-Up Wiring Installation
The system can be equipped with external batteries for proper operation when local AC power fails. The Back-Up
batteries are connected to the connector(CN3) of the MFB.
The External batteries must provide 24 Volts DC. This is generally accomplished by connecting two 12 volts batteries in a
series arrangement. Battery operation is controlled by the MFB. The MFB will provide charging current(maximum 0.5
amp) to the batteries during normal AC power operation. The MFB will automatically stop the battery operation when AC
power re-applied or low battery voltage detected.
The system operating time by external batteries is depend on several elements as follows, battery charge state, condition
of the batteries, capacity of the batteries, and the system configuration(number of station ports).
The MFB has one industry standard 9 pin RS-232C connector. The RS-232C ports are connected by 9-pin connectors as
shown Figure 3.5.2. Note that the communication settings are 9600bps(Max 38400bps), 8 bit data, no parity bit and 1
stop bit.
The RS-232C port only provides three(3) control signals such as TXD, RXD and ground.
It is recommended that the RS-232C serial cable whose length is below 10 meters is used.
Batteries are connected to the connector(CN3) of the MFB, as shown in Figure 3.5.1.
Warning :
-
Carefully check the battery polarity with cable colors(RED and BLUE) when connecting the battery to
system.
-
-
It is recommended to use a fuse(5A @250V) between battery and system.

3.6 DECT Installation
3.6.1 Overview of the DECT system
The wireless standard of the GDK-20W system is DECT(Digital Enhanced Cordless Tele-communications).
The components of the DECT system are a WTIB, base stations and wireless terminals. The GDK-20W system has the
three wireless terminal interface ports that is used to connect three(3) base stations. One port is prepared in the MBU,
the others are provided by WTIB that is installed to SLOT5 of the MBU optionally.
Base stations are installed throughout a facility to relay calls between wireless terminals and the GDK-20W office
telephone system. The GDC-335H and GDC-340H are wireless terminals. The wireless terminal users have access right
to the office telephone system (GDK-20W) feature in addition to being free to make and calls away from their desks. The
wireless terminal is small, light and easy to use. It also provides a display for alphanumeric information.

GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
A. GDK-20W Digital Wireless Key Telephone System
The MBU has one(1) wireless terminal interface port that is used to connect one base station.
B. WTIB (Wireless Terminal Interface Board)
The WTIB has two(2) wireless terminal interface(WTI) ports and can support the two(2) base stations.
The WTIB should be plugged into the SLOT5 of the MBU.
C. Base Station (GDC-200B)
The base station should be installed indoors and protected by surge because it is designed for indoor station.
It has a RF(Radio Frequency) Module(transmitter and receiver) that handles communication with wireless terminals
through the air link. It can be connected to a GDK-20W system via Wireless terminal interface ports.
Each base station provides similar coverage for a particular area call as a cell, and supports four(4) simultaneous calls
(four traffic channels). However, since individual wireless terminals are not continuously in call, the system may support
more than four wireless terminals:
In the GDK-20W system, Maximum 20 wireless terminals can be registered.
Base stations may be mounted on walls or desktops up to 300 meters away from the GDK-20W system using twisted one
pair cable (0.5φ, AWG 24). They are remotely powered (DC 30 volts) by the wireless terminal interface circuit.
The number of base stations used in a system depends on the area to be covered and the traffic density. The typical in-
house coverage is a 40 meter radius. In practice the cell size may vary between 10 meter indoors in worst case situation,
up to 200 meters outdoor in free space.
D. Wireless Terminal (GDC-335H, GDC-340H)
It is designed for ease-to-use. The LCD shows various call-information, and the keypad has a 12-dial pad and additional
keys that facilitate wireless terminal.
E. Single Slot Charger (330-SSC, 340-SSC)
The battery of a GDC-335H is charged by a 330-SSC and the battery of a GDC-340H is charged by a 340-
SSC.
39
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
3.6.1.2 How to make Calls
A. Before Making Initial Call
It is similar to other calls in a telephone system to make a call in the DECT system except that every call to or from a
wireless terminal involves establishing a RF link to the wireless terminal through a base station. In an idle status, a
wireless terminal scans a dummy bearer from base stations and locks to the base station with the strongest signal. The
dummy bearer is similar to the control channel in a cellular telephone system. If the wireless terminal can not synchronize
to a dummy bearer, it can not make a call.
System ID(PARK) is very important in the DECT calls. The Base stations should be assigned to a unique GDK-20W
DECT ID(PARK). Wireless terminals should be programmed with a system ID that matches a particular GDK-20W DECT
system before communicating with a base station in the system.
Calls to Wireless Terminal
The DECT system receives a call from an extension of the system.
To locate the called party, the DECT system sends a request containing the ID of the called wireless terminal to all base
stations.
The called wireless terminal responds to the base station onto which it is locked.
The RF link is established. The call then proceeds like other calls in the office telephone system.
Initiated Call from a Wireless Terminal
The wireless terminal locks onto a base station and initiates a RF link.
The base station transmits call information to the DECT system. The call then proceeds like other calls in the office
telephone system.
B. Controlling a Call
During a call, interaction occurs mainly between the wireless terminal and a DECT. The wireless terminal accepts input at
the keypad by user and sends the information to a DECT via base station. The DECT handles most of signaling functions
and controls the display of wireless terminal.
C. Terminating a Call
Call termination involves releasing a voice channel and transiting a wireless terminal to a standby status. When DECT
recognizes that a call has terminated, it sends a release message to a base station. The base station and wireless
terminal are released.
In some cases, the base station should initiate call termination by sending a message to the DECT. Loss of wireless
terminal power and interference with the RF signal are examples of events that cause the base station to terminate a call
abruptly.

A. WTIB
The WTIB is installed to the SLOT5 of the MBU and has the two(2) wireless terminal interface ports.
Figure 3.6.2 shows the layout of the WTIB.
Figure 3.6.2 WTIB
B. Base Station
Figure 3.6.3 shows a base station.
Figure 3.6.3 Base Station
41
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
Base stations may be mounted on wall or desktop up to 300 meters away from the wireless terminal interface ports using
a twisted one pair cable(0.5φ). The system supports max. three base stations.
In typical office environments, each base station has a broadcast range of 50 meters and supports an area of 8,000
square meters. In settings where the absence of any obstruction provide perfect line of sight conditions between a base
station and wireless terminal users and there are no atmospheric limitations, the range may increase to max.200 meters.
LEDs on the PCB of a base station provide diagnostic information for base station status.
Antenna Diversity
Spatial diversity at the base station is implemented by using two antennas. The antenna providing the best signal for
each time slot is selected. This is performed on the basis of the RF power level and alternatively the quality information.
In DECT, the BER(Bit Error Ratio) is affected by multi-path propagation not only in terms of signal fading but in terms of
time dispersion, which leads to ISI(Inter Symbol Interference). Antenna diversity not only reduces the fading probability
but mitigates the effect of time dispersion.
Power Feeding
The base station is DC powered from the WTI ports by phantom power feeding circuit between a WTI port and a base
station.
Roaming
Roaming is the movement of a wireless terminal from one base station coverage area to another base station coverage
area, where the base stations enable the wireless terminal to make or receive calls in both areas. The system supports
roaming function.
Hand-over
The GDK-20W DECT provides a seamless hand-over, almost undetectable by users as they move from one radio cell to
another.
Digital Voice Quality
The GDK-20W DECT uses advanced digital technology to provide high sound quality as almost equal to fixed line
telephones. Speech coding uses 32kbps ADPCM(Adaptive Differential Pulse Code Modulation) conforming to CCITT
recommendation G.721.
Multiple Simultaneous Users
The GDK-20W DECT accommodates multiple users(12 users) in simultaneous conversation with no degradation in

3.6.2 System Configuration
The GDK-20W DECT is used in single cell or multi-cell.
3.6.2.1 Before Installation
Followings are the factors that affect the quality of service for the GDK-20W DECT.
•
•
•
•
•
Location of base station
Number of wireless terminal users within a base station range
Obstructions between base station and wireless terminal
Coverage area
Desired quality of service
The purpose of this section is to provide you with information and explain tasks that you should complete to
ensure the best operation of the system.
The following procedure is very helpful to check the coverage region and install the base station:
1. Site survey (see the sub-clause A)
2. Judge where to place bases on plan drawing (see the sub-clause B).
3. For each base, check coverage tool (see the sub-clause C and CRS Tool Manual).
4. Plot limit line for each base station.
5. Check for shadow area.
6. Adjust base position for shadow area or add base if not possible.
7. Consider traffic 5 calls per cell add to plan.
8. Install the base station (see the 3.6.3 Hardware Installation).
9. Check with 335H GAP (except 340H GAP) handset using RSSI (displays only one base station at a
time, limit is -80 dbm: see the sub-clause D)
10. Walk with 2 handsets, monitor for voice quality and ‘OUT OF RANGE’ message.
11. If it is OK, finish it.
A. Site Survey
1. Get building blue prints.
2. Check building material and thickness.
Note the general construction materials used in walls and doors between multi-story buildings, and
window coatings and coverings, if any. Also note any large metal objects, such as equipment, doors, and
fluorescent lamp shades.
In general, signals are attenuated to some lower degrees when they should pass through any barrier,
however, some materials such as metal attenuate much degree.
Note
a. Consider high traffic areas, such as conference rooms, cafeterias, and manufacturing floors.
b. Consider office locations and number of wireless terminal users within the site.
46
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
B. Base Station Broadcast Range and Location
1. Base Station Requirements
To determine the number of base station in a system, you should consider base station broadcast range.
2. Base Station Range
In a typical office environment, each base station has a broadcast range of 50 meters and supports an
area of 8,000 square meters, but a broadcast range depends entirely upon office environment. Where
the absence of any obstruction provides perfect line of sight conditions between the base station and
wireless terminal users and if there are no atmospheric limitations, the range may increase to 200
meters.
The following base station broadcast ranges can be used as a rough guide to plan the base station
positions:
z
z
z
In line of sight, the base station has a range of about 200m.
In hall, the base station has a range of 40-70m.
In buildings, the base station has a range of about 25-40m. It assumes that walls are made of light
brick, plasterboard or wallboard with metal frames. Normal electrical wiring, central heating pipes,
office furniture and desktop computer equipment have no significant effect.
r = Typical office environment : up to 50 meters
r = Line of sight : up to 200 meters

3. Base Station Location on the Plan Drawing
Determine the location of the base station on the plan drawing according to the previous information
based on the base station broadcast range.
47
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
Once you have completed the steps described in Site Survey on sub-clause A and determined the
number of base stations you need, you should determine where to install the base stations for optimum
coverage and operation of the GDK-20W DECT.
C. CRS(Cell-Coverage Region Survey) Tool
This section provides general guidelines and examples for determining location of base station in the site.
For more information, see the CRS Tool Manual.
For the easy installation, LGE prepares the portable tools which consist of the base station and the wireless
terminal.
Figure 3.6.11 Installation Configuration using the CRS Tool
General Guidelines
1.
2.
Place the base stations to maximize direct line of sight between wireless terminals and base station
antennas. Mounting base stations as high as possible will satisfy this guideline.
Place the base stations to minimize obstructions near antennas. If you mount a base station on a wall,
place it higher than the average tall person and do not mount it near doors that could temporarily
obstruct antennas when the door is opened.
3.
4.
5.
Antennas on wall-mounted base stations should be parallel to the wall.
Centralize base stations within the area that you intend to cover.
When rule 1 cannot be observed, place base stations so that signals begin their paths with a clear line
of sight and then bend at the end of their travel to a receiving antenna. It limits the affect of signal
fading.
6.
7.
To minimize blocking in high traffic area, install the base stations required to meet the estimated traffic
demand. When multiple base stations are needed in the same location, you may mount base stations
as close as one meter apart (to avoid one obstruction to the other according to the rule 2).
The base stations are designed to use frequencies that are not in use yet, so there is no problem of
interference between base stations that are mounted near each other.
48
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
8. In multi-story environments, it is the best to plan coverage for each floor separately. However, because
RF signals can travel between floors, a single base station could support multiple floors as long as
base station broadcast area, traffic requirements, and other general guidelines are kept in mind.
Usually, DECT wave is attenuated by reflection indoors. In order to minimize attenuation, when you
install a base station on the wall, give at least three-wave-length intervals. The intervals should be at
least 45 centimeters because the wavelength is 15 centimeters at DECT frequency.
The best communication environment is when a base station and a user are in the same height. In
office environment, however, it is desirable to consider office furniture to minimize reflection, diffraction
and scattering of DECT wave when you set the position of a base station.
The appropriate position for a base station is where 1.8meter above from the floor and 0.5 meter below
from the ceiling. The top of iron office furniture such as a cabinet or a desk is not a good position. Keep
away from electronic equipment such as a copy machine, a printer or a computer. And the lower wall of
a corridor where many people pass by, corner of a wall, and narrow indoors also should be avoided.
Attenuation
When determining the location of base station, you should consider the effects of attenuation. Attenuation is
the loss of strength of a RF signal due to distance, antenna positioning, and obstructions. The guidelines
provided in Location of Base Station on sub-clause C take attenuation into account, but this section provides
additional important concepts.
The magnitude of change in signal strength is measured in decibel(dB). Increasing or reducing of 3dB
results in doubling or halving signal power strength.
Distance
[Table 3.6.1] shows the signal attenuation caused by distance in direct line of sight condition.

[Table 3.6.1] Signal Attenuation in Direct Line of Sight Condition
Obstructions
RF signals are also attenuated by obstructions in their paths. [Table 3.6.2] shows the attenuation caused by common
materials in a building. You should try to limit the loss to 60dB.

[Table 3.6.2] Signal Attenuation Caused by Building Materials
Although signals can travel through obstacles, you should place base stations so that signals begin their travel with a
clear line of sight and travel through obstacles afterwards. In the example shown in Figure 3.6.12, the base station is
placed to maximize line of sight in both corridors.

Figure 3.6.12 Maximizing Line of Sight
Fading
Fading refers to the attenuation caused when a signal is reflected and receiving antenna receives multiple
instances of the signal. A direct signal is always stronger than a reflected signal.
Base station is designed with two antennas and the capacity to choose the best suited antenna for carrying
the strongest signal. This design minimizes chances of fading.
Although signals can travel around corners, you should place base stations so that signals begin their paths
with a clear line of sight as illustrated in Figure 3.6.12 and then bend to travel to a receiving antenna. It limits
the effect of signal fading.
Shadowing of the radio signal
The following items may well cause shadowing of the radio signal:
z

Thickness of walls, especially cavity walls and reinforced concrete walls.

Thickness of concrete floors.
Traffic Guidelines
Each base station supports four simultaneous calls, but because all users are not simultaneously in call
statistically, a base station can support a greater number of wireless terminal users in practice.

The location of the GDK-20W System.
Cabling details. Include a specification of cables already present on the site and a list of new cabling required.
Include the distance between a base station and a WTIB for existing and new cabling.
Copies of the maps of the site with the positions of base stations and the cell boundaries. Different cell boundaries
can be marked with different patterns to avoid confusion, i.e. dotted, dashed, dot dash, etc. Do not use colors as
these may be lost when photocopying.
z
Use the following numbering conventions:
xwyy refers to the identity of the base station, where;
x is the level (-1 is basement, 0 is ground floor, 1 is 1st floor, etc.)
w is the base station number.
yy is the base station position number. This number should be unique.
xcyy refers to the identity of the cell, where;
x is the level at which the measurement was made. (-1 is basement, 0 is ground floor, 1 is 1st floor, etc.)
c is the cell number.
yy is the base station position number that is being measured.
51
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
A list of possible configurations will help the customer to decide exactly what is required. A specification of where base
stations should be placed. This can be marked on the survey map, but additional information such as height and fixing
instructions should be included where appropriate.
A specification of the areas that will be covered by the base station and the areas that may cause problems. This can be
useful when testing the system.
The theoretical maximum number of overlapping cells is 10, if all time slots and frequencies are used. If not all time slots
and frequencies are used, this value is higher. However this is unlikely to be reached in practical situations.
For a large site where a thorough survey has been impossible, it may be prudent to add additional base stations to the
product offer to allow for unforeseen problem areas.

3.6.2.2 Examples
A. Example 1 - Centralizing Base Stations
Figure 3.6.13 shows a site with factory and adjoining office area. Both base stations are placed in the
manufacturing area to accommodate with more users in that area. However, base station BS2 is placed
closer to the office area to provide coverage in the office area and maximize line of sight through the
doorway. This is especially important if the wall between the office and manufacturing area is concrete.
To satisfy guidelines 1 and 2, the base stations are mounted on the ceilings and away from any potential
obstructions to the antennas.
If there is another area to the left of the manufacturing area, moving the base station BS1 to the left is
probably allowed to support users in that area as well. If the manufacturing area does not obstruct base
station antennas, their broadcast ranges could reach up to 200 meters.

B. Example 2 - Base Station Coverage in Adjoining Areas
The corridors can act as natural pathways for RF signals. When you are trying to cover two types of area,
placing a base station near a corridor may optimize coverage in both areas.
In the site shown in Figure 3.6.14, the entrance from the manufacturing area into the café is a high traffic
area. Placing a base station in the entry area of the cafe will block line of sight to other areas in the cafe.
Therefore, BS2 should be centrally located in the cafe area. BS1 is centrally located in the manufacturing
floor area, but aligned with the entrance into the cafe to provide coverage into the cafe.

WTIB Installation
In a GDK-20W Digital Wireless Key Telephone System, the WTIB is a base station interface board that is installed in the
SLOT5.
If the WTIB is installed in a power-on system, the system and/or WTIB can be damaged. Thus after system power is off,
the WTIB should be plugged in/out to/from the system.
Base Station Installation
Before mounting base station permanently, you should determine a suitable location providing the best coverage.
Employing the GDC-200B mounting template attached at the last sheet of installation manual, mark the location of the
two screws to mount the Base.
Mounting Base Station - 1
The weight of a base station is light as approx. 420g, so it can be mounted on a masonry or dry-wall surface, wooden wall,
or partition wall. The distance between mounting holes is 121mm as shown in Figure 3.6.18. The base station is
mounted with 1 1/2 inch or longer screws. Drill pilot holes in the two locations, insert the screws and tighten leaving about
3mm gap between the wall and screw head. Mount the base station on the screws and tighten the screws securely.
57
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
Figure 3.6.18 Wall Mounting of Base Station (without wedge)
Before mounting base station permanently, you should determine locations that provide the best coverage. The wall
mounting procedure of a base station is as follows:
Drill two 3.5 mm holes in a fixed wall. To properly position the holes, you can measure the tags on the base station or
mark the surface through the tag eyelets while holding the base station in place.
Insert anchors into the drilled holes. Then insert screws in the anchors, leaving a 3 mm gap between the wall and screw
head.
Mount the base station eyelets on the screws.
Mounting Base Station - 2 (Using Wedge)
Installing the Base Station using the wedge,
Determine at first the location on wall where the wedge prepared for mounting the base station is to be fixed.
The wedge should be settled by using two screws on the wall.
And insert the base station pulling down into the wedge.

Base Station Cabling
The Base Station is connected to the WTI(wireless terminal interface) ports of GDK-20W KSU by a twisted one pair
copper line. The following rules should be obeyed:
The cable for connecting the KSU with a base station should be a twisted pair cable.
The cable for connecting the KSU with a base station shall be separately cabled. This connection shall be cabled
separate to the building cabling using one pair CAT5 cabling.
Twisted pair shielded cables should be used with all outdoor configurations.
The following characteristics should be observed for all cables:
DC resistance: The resistance of a conductor should not exceed 73.4 ohm per km for a temperature of 20 degree.
Attenuation: The attenuation of any pair should not exceed 17 dB per km on condition of a temperature of 20 degree and
frequency of 1 MHz.
Characteristic impedance: Characteristic impedance should remain in the range of 100 ohm _ 15% for a frequency of 1
MHz.
Crosstalk: The total crosstalk of any pair (Far-end and Near-end crosstalk), measured over a line length of 1800 metres
should not exceed 40 mV.
The maximum connection length depends upon cable size(φ). [Table 3.6.4] shows the resistance and the maximum cable

67
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
4.2 The Basic Features of ISDN Device (S-Interface)
1. ISDN Devices
1) There are many ISDN Devices. ( ex. ISDN Phone, Video-Phone, G4 Fax, PC-Card, etc.) GDK-20W
supports all ISDN Devices which is compatible with Euro-ISDN (ETSI ISDN Specification) till now on.
2) ISDN Devices can call another station on the GDK-20W and access ISDN CO Lines.
3) Current LCD Display on ISDN Device is its own Device Feature, not GDK-20W System’s Feature.
2. Supplementary Service for ISDN Device
1)
In GDK-20W, ISDN Station can access the following features,
A. ISDN Sub Addressing
B. MSN
C. Intercom Call
D. CO Line Access
E. CO Line Hold.
F. CO Line Transfer.
G. Etc.
2) ISDN Sub Addressing.
Sub Addressing can be programmed by Station Base Program(Main Menu2) - ISDN Station
Attribute(Sub Menu2) - Sub Address(Terminal Menu1), its range is YES/NO(Default: NO).
If ISDN Station is allowed sub addressing by admin. program, in any station
user who wants to call to ISDN station has to dial the station No and sub address
for that ISDN station.
For using ISDN Station’s Sub Address, there is further program on the ISDN Devices. Please consult your ISDN
Devices manual for programming ISDN Device’s Sub Address.
Sub Address is useful to the following Features for decoding the single ISDN Device from ISDN Devices on the
same S-Interface (bus),
(1) Intercom Call to ISDN Station
(2) DID Call to ISDN Station
(3) DISA Call to ISDN Station
On the other features, Sub Addressing does not effect ISDN Station’s behavior.
3) ISDN MSN Addressing.
MSN Addressing can be programmed by Station Base Program (Main Menu2) - ISDN Station Attribute(Sub Menu2) - MSN
(Terminal Menu3), its range is YES/NO(Default: NO).
If ISDN station is allowed MSN addressing by admin. program, in any station user who wants to call to ISDN station
has to dial the station No and MSN address for that ISDN station.
For using ISDN Station’s MSN Address, there is further program on the ISDN Devices. Please consult your ISDN Devices manual
for programming ISDN Device’s MSN Address.
68
GDK-20W DIGITAL WIRELESS KEY TELEPHONE SYSTEM
MSN Address is useful to the following Features for decoding the single ISDN Device from ISDN Devices on the same S-Interface
(bus),
(1) Intercom Call to ISDN Station
(2) DID Call to ISDN Station
(3) DISA Call to ISDN Station
On the other features, MSN Addressing does not effect ISDN Station’s behavior.
4) ISDN Intercom Call.
Any station can call ISDN Devices by dialing station no. S-Interface has two stations no. So, user
can call ISDN Devices by dialing one of two pre-assigned stations no. There is no difference
between calling ISDN Devices with the two stations no which is assigned the same S-Interface.
If ISDN Device is set to Sub Addressable ISDN, it needs further one digit for calling that ISDN
Device.
5) ISDN CO Line Access.
CO Line Access of ISDN Device is the same as that of Single Line Telephone ( SLT )
6) CO Line Hold.
In GDK-20W, system does not use DTMF Receiver for recognizing user’s dialing digit. So if user
want to use Hold/Transfer Feature on ISDN Device, ISDN Device has the capability of sending
Keypad Facility Information on the Information Message.
If possible, holding CO Line Call, send “*#” ( Keypad Facility ), then connected CO Line Call is held
and user can hear Intercom Dial Tone.
Retrieving Held CO Line, send “*#” ( Keypad Facility ), then the held CO Line Call is retrieved.
Please consult your ISDN Device’s Manual for sending “Keypad Facility” after connection.
7) CO Line Transfer.
In GDK-20W, system does not use DTMF Receiver for recognizing user’s dialing digit. So if user
want to use Hold/Transfer Feature on ISDN Device, ISDN Device has the capability of sending
Keypad Facility Information on the Information Message.
If possible, holding CO Line Call, send “*#” ( Keypad Facility ) and dial the station No to transfer the
call, then connected CO Line Call is held and user can hear Intercom Dial Tone.
Retrieving Held CO Line, send “*#” ( Keypad Facility ), then the unanswered CO Line Transfer Call
is retrieved.
Please consult your ISDN Device’s Manual for sending “Keypad Facility” after connection.
8)
Etc.
ISDN station accesses the above features. Other features are not supported currently.
ISDN station cannot be the master of Conference.

Normal CO Line Features of STIB/BRI is the same as Analog CO Line. Normal CO Line Features are
described GDK-20W Manual. Consult your GDK-20W for normal CO Line Features.
2. MSN
GDK-20W will receive some called party number from PX via DID line, then looks up the MSN address
TABLE, ISDN Program (Main Menu 4) - MSN Table (Sub Menu 9) to provide ring signal to an ISDN
internal port.
GDK-20W will send the information including the called party number to the ISDN station that is
ringing.
(1) Maximum table entry : 24.
(2) The CO line should be programmed as DID Line, CO Base Program (Main Menu 3) – ISDN
Attribute(Sub Menu 2) - DID Use(Terminal Menu 4).
(3) If the called party number is not matched with MSN table then GDK-20W will treat the call like
as DID.
(4) If the called CO line number is not programmed then search all tables.
(5) If there is matched CO line number in MSN address table then search only matched entry of
the table.
(6) Maximum 8 device can be connected to a S0 port.

SECTION 6. ADMIN PROGRAMMING
6.1 GENERAL DESCRIPTION
6.1.1 INTRODUCTION
The GDK-20W Key Telephone System can be programmed to meet each customer's individual need. All programming is
done at station 100(DKT 1) using KD-24D, KD-36D, LKD-30D digital key telephone.
Upon entering the program mode, the key telephone at station 100 cannot operate as a normal telephone but as a
programming instrument with all of the buttons redefined. The keys of the dial pad are used to enter the various data
fields and to enter numerical information. The 24 buttons located at the top of the phone (Flex Buttons) are used to
indicate the specific data field and to enter information. Sometimes [SPEED] button is used to delete the data.
See TABLE 6.2.2.1 - 6.2.2.10 for default data. If this pre-programming suits the customer, additional Admin program is
not necessary. To change admin data, the user enter the admin. programming mode and select program code. During
Admin programming, other keysets in the system operate normally.
When Admin programming, LCD and LED’s indicate current programmed data and status. If the programmer enters
correct data, then LCD and LED’s show the entered data and the data is stored in the temporary buffer area. Real
system databases is not changed and has no effect on telephone operation unless permanent updating procedure is
executed. Pressing [HOLD/SAVE] button, all data in the temporary buffer (same as LCD and LED’s show their status)
is saved into permanent memory. Tones are provided to let the programmer know whether data entry is correct
(confirmation tone) or not (error tone).
