Overview

This chapter describes the general introduction of wireless LAN, functions of

OfficeServ 500 wireless LAN, components of OfficeServ 500 wireless LAN, and

specifications for WBS24, 8WLI Card and WIP-5000M mobile phone.

1 Overview of Wireless LAN

The LAN can be distinguished into two different kinds, wired LAN and wireless
LAN, depending on the mobility and presence of stations.
The wireless LAN converts data between personal computers or between servers into
radio waves or optic signals, and transfers/receives them wirelessly. When installing a
network, either radio frequency(RF) or light is used to install a network from hub to
client.

Advantages of Wireless LAN

The advantage of using LAN are described as follows :

 Installation and maintenance are simple that the relevant personnel and

equipment can be easily replaced. There is no need to do additional power line
work.

 It is easy to install a network in an emergency situation
 It supports full user mobility in such applications as mobile station and portable

terminal.

 It solves cabling problems on the open sites where wiring is difficult, such as

exhibition, seminar, registrar, temporary building, and construction site.

 It solves the problems of network stoppage during natural disasters.
 It provides user mobility for mobile station and portable terminals in such areas

as the department stores, museums and factories.

2 Overview of OfficeServ 500 Wireless LAN

The OfficeServ 500 system, which is the key telephone system of Samsung, offers

voice or data service in a wireless LAN and can simultaneously send/receive voice
and data.
The wireless LAN service is offered through WLAN Base Station 2.4 GHz(WBS24),
which is an Access Point(AP) device. The WBS24 is classified into two types as
follows :

Wireless LAN Service Through the WBS24 (Combo)

The WBS24(Combo) interfaces with the OfficeServ 500 system through LAN and

offers the voice/data service.

 WBS24(Combo) : Offers the voice service through the 8WLI card that functions

as the wireless LAN. One 8WLI card supports up to eight WBS24(Combo)s.

 The WIP-5000M is used as a terminal for the voice service.
 Laptops on which a wireless LAN card is mounted or PDAs are used for the data

service.

Wireless LAN Service Through the WBS24(Basic)

The WBS24(Basic) interfaces with the IP network through LAN and offers the
voice/data service.

 WBS24(Basic) : MGI1/2/3 or ITM3, which functions as a VOIP gateway, offers

the voice data.

 The WIP-5000M is used as a terminal for the voice service.
 Laptops on which a wireless LAN card is mounted or PDAs are used for the data

service.

 The voice service is provided even in no-wired LAN environment.
 The quality of service(QoS) is guaranteed using the exclusive voice path.

 Since the OfficeServ 500 System supplies power remotely to the WBS24, no

separate electric wiring work is needed.

 The transmission distance between the OfficeServ 500 System and the WBS24

is 600 meters, so the cell can be easily designed.

 Since the built-in phone function is supported, a phone number can be assigned

instead of an IP address when registering a user.

 The call path generation/maintenance and handover functions are provided.
 The echo cancellation and voice codec(G.729, G.723.1) functions are provided.
 The system supports the back-up battery, so the phone conversation can be

maintained during an electric failure.

 Even if the ISM band is used, the VoIP is supported. So, there are almost no

interferences.

 Easy upgrade
 AP O & M function

Extension of the transmission distance

In case of the wired LAN, the transmission distance is only 100 meters in maximum.

To extend the distance, either hub or repeater is needed.

Main Processor

The main CPU used in the 8WLI is Motorola’s MC68000/MC68008 core series,
which enhanced the communication function.
The major specification of CPU is as follows :

 Supports the interrupt mode(Normal/Dedicated mode)
 Supports On-Chip 1152 byte Dual Port RAM
 Supports 3 timers
 Supports the selection of 4 programmable chips
 Supports 3 SCCs(Serial Communication Controllers)
 Supports various protocols
 Supports various physical interfaces

The CPU is the central control part that leads the performance of programs in the
board, and basically controls the memory and main components for performing the
program. The clock used for the program performance is the oscillator with

16.384MHz frequency, and transmits/receives 16bits data operating with the memory.
The interrupts are handled using the dedicated modes, and their uses are described in
the table below.

Table 1.1 Interrupt Information on 8WLI CPU

Level() Name Remarks

NMI(7) ABORT For debugger

INT(6) DASL INT 16×DASL

INT(4) DMC RX0 PB11(4×DASL)

INT(4) DMC RX1 PB10(4×DASL)

INT(4) 10m sec TIMMER1

INT(4) SIO SCC3

INT(4) INT TX0 PB9(4×DASL)

INT(4) INT TX1 PB8(4×DASL)

INT(1)

Since several interrupts data are

multiplexed onto level4, the processing of

DMC RX and TX interrupts may get

affected.

To prevent this, 10ms interrupt is lowered

to level3 by S/W while performed routinely.

So, even during the 10m sec interrupt

performance, the DMC UART interrupt can

be processed.

Flash Memory

The OfficeServ 500 System uses the flash memory of 512Kword capacity.

The AM29F800B of AMD is used, and this operates with the CPU on the 16 bits
mode for transmitting/receiving data.
In the flash memory, the programs for the 8WLI to perform the relevant functions,
including a booting program, are saved. When the program is changed, the program
can be upgraded using SIO(Serial Input Output) through the UART.

CHAPTER 1.Overview OfficeServ 500 Wireless LAN Service Manual/Ed.00

Page 1-10

© SAMSUNG Electronics Co., Ltd.

SRAM

Two SRAMs of 256 Kbyte X 2 capacity are used, and they operate with the CPU on
the 16 bits mode for transmitting/receiving data. The KM684000LT of SAMSUNG is
used.

Asynchronous Dual Port RAM

The DPRAM is used for data transmission with the main board of OfficeServ 500

system.
The components used for IPC(Inter-processor communication) are the CY7C136­55NC of Cypress, and this can read/write 2Kbyte data at the same time.

DMC (Digital Module Control)

The 8WLI has 16 DASL links. To control these, one DMC chip is used for 8 DASLs.
Therefore, a total of 2 DMC components are used, and the used components are
STL7052E SAMSUNG ASIC. They can handle interrupts and process data channel
transmission. The major functions are described as follows :

 The DMC buffers serial data from 8 DASL transmission chips and transferred to

the CPU, and serially transfers the transmission data from the CPU to each
DASL.

 The DMC muxes the interrupts occurred at the initial activation of DASL to send

one source to the CPU, and saves the event changes for each DASL transmission
chip.

 The DMC assigns highway timeslot for each DASL chip to be able to program.

DASL (Digital Adapter Subscriber Loops)

The wired interface between the 8WLI and AP(WBS24) uses the DASL components
of NS. One DASL link has the transmission speed at 144kbps, and there are 2B+1D 2
voice channels and one data channel. Since two DASLs for each WBS24 are used,
there are 4B+2D, 4 voice channels and 2 data channels. However, only one data
channel from 2 data channels are used, leaving the one at rest. Also, the transmission
speed of data channel is set at 16 kbps.
The DASL link is connected to two wired cables, so each AP(WBS24) is connected
to 4 wired cables. The 24AWG UPT(Unshielded Twisted Pair wire) cable is used,

and the maximum extension distance is 600M.

Echo Canceller (ZL50232)

Impedance might be mismatched or line echo might occur due to delay during data
processing in the hybrid system. To remove the echo, add the Echo Canceller in the
voice path. The default of the echo tail(echo length) is 64 ms and the echo tail can be
expanded to 128 ms.

OfficeServ 500 Wireless LAN Service Manual/Ed.00 CHAPTER 3. Installation

Power Supply

The power of WBS24 is supplied from the system using the remote power feeding
method. So, -48V DC power of the system is supplied from the 8WLI to the WBS24
through the DASL transmission line. The transmission cable connected between the
WBS24 and the system is composed of 4 strands grouped into 2 pairs. The ground
polarity is supplied to one pair(2 strands), and to the other pair(2 strands), -48 V
voltage DC power is supplied. The maximum wire distance that power can be
supplied is 600M, in case of 24AWG UTP(Unshielded Twisted Pair wire) cable.

3.3 WBS24 (Combo)

3.3.1 Overview

The WBS24(Combo) is the AP(Access Point) for using the wireless LAN service.

AP(Access Point)

AP(Access Point), one of the wireless LAN devices, connects the wired LAN to the

wireless LAN. AP is usually a stand-alone device, which can be used by plugging into
Ethernet hub or a server. One AP hands off to another AP depending on the location
of a user, just like cellular phone does. Therefore, a user can use a mobile phone
while moving around.

3.3.2 Major Functions

The major functions of WBS24(Combo) are as follows :

3.3.3 Interface

The WBS24(Combo) consists of wire processing part and wireless processing part.
The wire processing part has two wire interfaces : ISDN BRI interface connected to

OfficeServ 500 system and IEEE 802.3 Ethernet connected to LAN. The wireless

processing part has 2.4 GHz frequency bandwidth of wireless LAN, which complies
with the RF interface based on IEEE 802.11b standard.

Wired Interface Interworking with the OfficeServ 500 System

From a wired interface, the ISDN BRI interworks with OfficeServ 500 System. The

ISDN BRI service is implemented using the Digital Adapter Subscriber
Loops(DASL) chip of National Semiconductor Co., Ltd. This is not a standard ISDN
BRI chip, but Samsung uses it own protocols. Its data transmission speed is 144 Kbps
and there are two voice channels and one data channel. The wired section, which

inter-works with OfficeServ 500 System, sends and receives signaling data for voice

data transmission as well as voice communication.

Wired Interface Interworking with LAN

The wired Ethernet interface can access to LAN with the 10/100BASE-T port and
send/receive data via Internet, other than voice. The wireless processing part can
send/receive voice data for wireless voice communication, as well as data for
wireless access to Internet. The maximum data transmission speed between wireless
sections is up to 4 to 5 Mbps. One unit of WBS24(Combo) can process simultaneous
calls on 4 channels.

Wireless Interface

The wireless interface uses 2.400 to 2.4835 GHz of wireless frequency bandwidth
and meets the IEEE 802.11b standard. Voice can be sent and received across the
wireless sections using a voice-specific terminal. The Voice over WLAN
sends/receives the voice packet data, and laptop computers and PDA send/receive the
data packet across the wireless sections. 13 wireless channels are used in Korea and
11 wireless channels are used in the U.S.
The wireless interface occupies 22 MHz of bandwidth per wireless channel and the
interval between center frequencies is 5 MHz. Therefore, to be a clear channel that
does not interfere with other wireless channels, it should be 4 channels away from
other channels. The wireless processing part sends/receives voice data for wireless
voice communication, as well as data for wireless access to Internet. The maximum
data transmission speed between wireless sections is up to 4 to 5 Mbps. One unit of
WBS24(Combo) can process simultaneous calls on 4 channels.
