CHAPTER 1

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.

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

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.

Major Functions

The wireless LAN of OfficeServ 500 System has the following features :

 Wireless Standard : IEEE 802.11b  Data rate : 11 Mbps(Max), 5.5 Mbps, 2 Mbps, 1 Mbps  Modulation : CCK, BPSK, QPSK  Network architecture : Ad-hoc, Infrastructure  Security Function : WEB 64/128-bit encryption  Output Power : Max. 100mW(NIC Card 70mW)  Channels : 13 channels(Korea)/11 channels(USA)  Interface : PCMCIA  Frequency : 2400~2483.5 MHz  Antenna Gain : 2.0 dBi  Beam-Width : Omni directional(Dipole)  Diversity Support

Page 1-2

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

 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.

3.2 8WLI

3.2.1 Overview

The 8WLI card, a service board providing the wireless solution to the OfficeServ 500

System, provides the wired interface in between the OfficeServ 500 System and

WBS24(WLAN Base Station 2.4 GHz), which is the wireless LAN’s AP(Access

Point).

The wired interface method, a digital method, uses 2B+1D DASL(Digital Adapter

Subscriber Loops), and communicates with the upper main CPU board using the

DPRAM(Dual Ports RAM) interface of the IPC(Inter Processor Channel) for

transmitting/receiving messages.

A maximum of one 8WLI card can be mounted on the OfficeServ 500 System, and

the 8WLI can interoperate with a maximum of 8 WBS24s. Since two DASL lines are

connected to one WBS24, simultaneous phone calls are possible through 4 voice

channels of 2 x(2B+1D). Therefore, one 8WLI board can support a maximum of 32

voice channels.

The WBS24 is supplied of –48 V DC power through the DASL line, and can

transmit/receive voice and signaling data in between the 8WLI and WBS24.

3.2.2 Major Functions

The major functions of 8WLI card are as follows :

 Provides the wired interface between the AP(Access Point) and the system to

transmit/receive voice and signaling data.

 Supports 32 voice channels for each card.  Either provides or blocks -48V DC power supply to the WBS24.  Performs the initiation for the VoIP over WLAN service.  Manages information on all terminals for voice service and provides the service

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.

Ta ble 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

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)

Page 1-10

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)

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

5 Setting the System DB

Before using the WIP-5000M terminal on the OfficeServ 500 System, appropriate

values for the following items must be set in accordance with the operating environment, using the MMC program.

5.1 Setting the System KEY

System KEY is used internally in the system. System ID KEY is an authentication parameter used in the user identification procedure when registering a WIP500M mobile phone to the wireless LAN system. The default value ‘00000’ must be modified to another value(at most 5 characters long) using the MMC 845 program, to activate the wireless LAN.

5.2 Setting the System ID

All terminals used in the wireless LAN shall have the System ID set for access. Scanning of this value is always possible at a general terminal, and this value can be modified to random characters for system identification when managing the system. The default value ‘WBS24’ can be modified to another value(at most 6 characters long) using the MMC 845 program.

5.3 Setting the WBS24

The wireless LAN Access Point, or the WBS24, must be activated to employ the wireless LAN. For voice service only, enter the SECOND WBS IP of the MMC845, and use the default values of the WBS24. However, to offer a wireless data service, the IP Address, Netmask, Gateway, and DNS, which are effective in the Intranet or Internet network, must be set at the Network Configuration DB for the WBS24 The default value may be modified to an environment with less interference by verifying the interference between cells for each WBS24.

Caution when setting the WBS24 Second IP

To use the Internet network, the first three digits of the IP assigned to the WBS24 and

the first three digits of the Second WBS24 IP of the WBS24 must be identical. If the IP assigned to the WBS24 and the Station is 168.219.149.xxx, then the Second IP of the WBS24 shall be 168.xxx.xxx.xxx.

Page 3-10

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

5.4 Assigning a terminal IP

Before registering a WIP500M terminal, an effective IP address shall be assigned to the WIP-5000M terminal using the MMC 848 program. This IP address shall be assigned for each terminal. Although this IP address may not be relevant when not using the data service, assign an effective IP address for later use of both voice and data services.

5.5 Authorizing the Terminal Register

A wireless LAN terminal shall be registered at the system DB in order to be used for

the OfficeServ 500 System. After authorizing the terminal register through the MMC

849 program, register the terminal following the registration procedure. The password used for entering the register authorization menu can be changed through the MMC 849 program, along with the previous password used for the OfficeServ

500 In addition, the WEP(Wired Equivalent Privacy), an encryption method for the

wireless LAN, is used to maintain data confidentiality in the wireless environment. Execute the MMC 849 program for authorizing a terminal register in order to register a terminal to the system. Once the terminal registration is complete, cancel the register authorization to restrict the registration of other terminals.

MMC Programming

Refer to ‘Chapter 5 MMC Programming’ of this Description for programming procedures

related to the wireless LAN.

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

6 Registering/Clearing the WIP-5000M Terminal

The WIP500M terminal must be registered to the system to be used in the OfficeServ

500 System Wireless LAN. This section introduces the procedures for registering and

clearing the register of a terminal.

6.1 Registering a WIP-5000M

1) Confirm if the system DB items are set according to the ‘Setting the System DB’

section of this chapter.

2) Register the WIP-5000M terminal at the register menu.

Refer to the ‘WIP-5000M User Manual’ for the register procedure.

3) The Network ID shall be entered correctly during the WIP-5000M register

procedure. Especially, the User ID and Password shall be identical to that of the system. If an error occurs during execution of register procedure, check the system DB settings and repeat the procedure above.

4) An extension number will be assigned to the WIP-5000M upon completion of

the terminal register.

6.2 Clearing a WIP-5000M

Where theft or breakage of a WIP500M Station causes a new terminal to be registered, registration of the previous terminal shall be deleted. The clearing procedure for the WIP-5000M is described below.

Clearing from the System

To clear the WIP500M in use, which is within the wireless LAN service area, set the normal mode through the system MMC. If the terminal is not within the service area or is not in use, delete the terminal’s registration DB in the system using the forced mode through the MMC system.

Clearing from the WIP-5000M

The terminal’s registration DB may be deleted from the WIP500M within the wireless LAN service area. Refer to the ‘WIP500M User Manual’ for termination procedure in detail.

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

7 Positioning the WBS24

This section introduces the cell in where the WBS24 will be installed, and describes the data transmission rate affected by the terminal’s location.

7.1 Cell Overview

The Figure 3.10 below illustrates the wireless transmission range of the WBS24. Theoretically, the range of a cell is presented as a circle, but in reality, the shape may be altered depending on the surrounding environment such as the location of the WBS24 or the surrounding structures. The boundary of a cell normally indicates the frequency range of WBS24, but actually, it should be perceived as a wireless service range and a boundary where a hand-off function to another cell is possible. The WIP-5000M is always connected to WBS24 within the cell range, and even when the WIP500M is in an overlapped range between cells, the WIP500M maintains communication with one cell at a particular time.

Cell Boundary

Figure 3.12 The Cell Boundary of WBS24

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

Single Cell

Generally, only one cell is configured for environments such as the wireless home terminal. Single cells are independent service areas, thus the cells do not affect one another. Configuration of single cells is illustrated in the Figure 3.11 below.

Cell #1 Cell #2

Figure 3.13 Single Cell Configuration

Multiple Cell

The multiple cell type is an environment where more than two cells are overlapped, and where the service for the terminal in use can be maintained while the Station travels between single cells. The actual configuration may differ from the figure below since the service areas of cells are altered depending on the positioning of the WBS24.

Cell #1

Figure 3.14 Multiple Cell Configuration

Cell #2

Handover

In order to provide a continuous service, the system must perform switch conversions when terminals are traveling between different cells. Especially in voice calls, the system must perform T-Switch conversions at appropriate times in order to maintain the call signal.

Location Register

By registering the current location of the terminal in a multiple cell environment, the system can easily transmit information to the terminal. Thus, the terminal shall register its location at the system in case it travels between different cells.

Page 3-14

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

7.2 Data Transmission Rate on Terminal Location

Data transmission rate and call quality are subject to the terminal’s location in an office. Refer to Figure 3.13 and Table 3.2 below.

CHAPTER 4

MMC Programming

This chapter describes the MMC programming procedures related to the wireless LAN function.

Method of MMC programming

Only the MMC programming procedures related to the wireless LAN are introduced in

this chapter. Refer to the ‘OfficeServ 500 Programming Description’ for the overall

system MMC programming procedures.

1 Before Programming

This section introduces the basic concepts, the phone buttons used for programming, and the cautions before starting the programming procedure.

1.1 Programming Overview

The OfficeServ 500 System settings can be easily modified using a connected digital

phone, and the program used to change the system settings through a phone is called the MMC(Man Machine Communication). The program used for system setting through a connected laptop computer or a PC is called the PCMMC. The MMC programs are classified into a program that the subscriber can program and a program that the subscriber cannot program, depending on the three subscriber levels : Engineer, Operator, and Subscriber. The Engineer and Operator programming requires a password for each programming, but the Subscriber programming does not need a password.

CHAPTER 4. MMC Programming OfficeServ 500 Wireless LAN Service Manual/Ed.00

1.2 Programming Button

The functions of the phone buttons for MMC programming are listed below.

Table 4.1 Program buttons

Button Function

▲ ▼(Up & Down) Change screen

Dial key Confirm status

Soft key Move cursor

Keypad Select item

SPK key Save data and proceed to next menu

HOLD key Delete previous input

TRSF key Enter program

1.3 Cautions when Programming

 Programming shall be done in an idle mode where the handset is on top of the

telephone set.

 Programming may be done on any extension of a digital phone.  Programming may not be done on a common single line telephone.  For digital phones not equipped with the LCD screen, use the dial key to enter

the numbers in the Description instead of the [▲volume▼] button. But since there are no Soft buttons, programming is limited. Therefore, with phones without the LCD screen, program only the Subscriber programs.

 When ‘INVALID DATA’ appears on the LCD screen, re-enter the correct data.  When no key is pressed for an amount of time(key program end time, default is

60 seconds), programming will end and return to idle mode.

 When the handset is lifted during programming, programming will end and

return to idle mode.

 When programming returns to idle mode by pressing the [SPK] key or the

[TRSF] key, or by lifting the handset, without confirming the modified data(pressing the ‘left’ or ‘right’ key of the ‘Soft’ button), or when the phone plug is disconnected, the data entered until then and the data on the LCD screen will automatically be saved as the new data.

2.1 Setting the MMC845 8WLI Parameter

This MMC modifies the 8WLI parameter. Set the network configuration with the 8WLI parameters, which are the SYSTEM ID, the System KEY, and the WBS24. The system KEY is used internally to distinguish between systems when registering a terminal. The default value is ‘00000’, but only when this value is modified to another value, an electric power will be supplied to the WBS24, thus enabling the use of the WLAN terminal, In addition, the System KEY serves as an identification ID when the WLAN terminal connects to the WBS24. The default value of the SYSTEM ID, ‘WBS24’, must be modified to another value in order to use a multiple system in one area. The DNS setting for WLAN is additionally described in this menu. Set the network configuration for eight WBS24s by setting the IP assignment, Netmask, and Gateway for each WBS24. These settings should be compatible with the Intranet since the network configuration setting is essential for data service. In addition, the RF frequency for each WBS24 should be selected. Currently in Korea, up to 14 frequencies may be selected.

The number of the WBS24 indicates the ID of the BTS for the WBS24. 1 to 24 are assigned to the WBS24(Combo), and higher numbers than 24 are assigned to the WBS24(Basic). The WBS24(Combo) is connected to three WLIs. WBS24(Combo) 1 to 8 are assigned to WLI 1 and WBS24(Combo) 9 to 16 are assigned to WLI 2. Also, WBS24(Combo) 17 to 24 are assigned to WLI 3.

Session Initiation Protocol(SIP) variables used for the WBS24(Basic) can be defined.

CHAPTER 5

Maintenance

This chapter describes how to solve problems via a LED status of WBS24, how to verify the WBS24 using a web browser and how to upgrade the WBS24 software.

1 Verifying the Status of WBS24

1.1 Status inquiry via the LED Status Indicators

With the LED indicators on the front panel of the WBS24, it is possible to verify the WBS24 status. When power is supplied to the WBS24, booting is allowed about ten minutes later. At this time, booting is indicated as the LD2 LED blinks regularly.(At this time, other LEDs can be unintentionally turned on, but they should be ignored). After receiving the initialized data from the system and when booting is completed, the LD2 LED blink will be disappeared. From this time, the on-line service becomes practicable. After booting is completed, each LED indicator of on-line status contains the uses as shown below.

It is not necessary to move the PC to the front of the WBS24 for the wireless

connections.

2) The subsequent procedure is as same as No.2 ~No.5 of ‘Upgrading the wireless connection.’ When several units of WBS24 are installed, upgrade according to the procedures as described above by connecting to the relevant IP address of the WBS24.

CHAPTER 5. Maintenance OfficeServ 500 Wireless LAN Service Manual/Ed.00

2.2 Upgrading via the Network Booting

This method is used to recover an error such as non-functioning flash memory. This method is impossible to upgrade wirelessly, but only through a wired LAN. If the WBS24 is connected with a wired LAN, it is possible to upgrade without any change on the WBS24. But if not the case, the wired LAN shall be connected between the WBS24 and the PC in order to upgrade the WBS24. This section describes how to upgrade the WBS24 based on the assumption that the WBS24 is connected to the wired LAN.

Preparing Materials

 PC server with a wired LAN port  Upgrade file for the network booting(bin type)

Upgrade Procedure

1) Set the PC to the TFTP/BootP Server for the network booting. Set the PC by using an application program for PC. This description explains how to set up using the ‘Cabletron TFTP/BootP Services 2.0 S/W. When another S/W is used, refer to the relevant usage of S/W.
