OfficeServ 500 Wireless LAN Service Manual/Ed.00 CHAPTER 3. Installation © SAMSUNG Electronics Co., Ltd. Page 1-7 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 to only authorized terminal.  Provides the initial registration service for wireless IP-Phone(WIP-5000M).  Provides the calling service to a terminal for voice service.  Supports the mobility between access points, as well as the handover function for a terminal for voice service.  Interfaces with the main CPU board of OfficeServ 500 System.

OfficeServ 500 Wireless LAN Service Manual/Ed.00 CHAPTER 3. Installation © SAMSUNG Electronics Co., Ltd. Page 1-9 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 CY7C136-55NC 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 © SAMSUNG Electronics Co., Ltd. Page 1-11 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 :  Provides the wireless RF interface that meets IEEE 802.11b, the wireless LAN standard.  Provides the wired LAN interface that meets IEEE 802.3, the wired LAN standard.  Provides the wired interface with OfficeServ 500 System whose speed is 144 Kbps and whose channel is 2B+1D.  Provides voice communication through OfficeServ 500 System using a Voice over WLAN phone.  Provides a wireless data service to data terminals that have the wireless LAN interface.  Separates the wirelessly received voice and data from each other and transmits them to OfficeServ 500 System and LAN.(If a voice message(signal) is received, it is transmitted to OfficeServ 500 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.
OfficeServ 500 Wireless LAN Service Manual/Ed.00 CHAPTER 3. Installation © SAMSUNG Electronics Co., Ltd. Page 3-11 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 Page 3-12 © SAMSUNG Electronics Co., Ltd. 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 Register a WIP-5000M terminal following the instructions below. 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 © SAMSUNG Electronics Co., Ltd. Page 3-13 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. Figure 3.12 The Cell Boundary of WBS24 Cell Boundary
CHAPTER 3. Installation OfficeServ 500 Wireless LAN Service Manual/Ed.00 Page 3-14 © SAMSUNG Electronics Co., Ltd. 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. 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. Figure 3.14 Multiple Cell Configuration 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. Cell #1 Cell #2 Cell #1 Cell #2

CHAPTER 4 © SAMSUNG Electronics Co., Ltd. Page 4-1 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 Page 4-2 © SAMSUNG Electronics Co., Ltd. 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.

CHAPTER 4. MMC Programming OfficeServ 500 Wireless LAN Service Manual/Ed.00 Page 4-4 © SAMSUNG Electronics Co., Ltd. 2 Programming This section describes the MMC programming procedure related to the parameter modification of the 8WLI and the WBS24. The MMC related to the parameter modification of the 8WLI and the WBS24 are listed below. Table 4.2 Wireless LAN related MMC MMC No. MMC Function 845 Sets 8WLI, WBS24 parameter 846 WIP INFO 847 8WLI RESET/STATUS 848 Setting for the WIP Data terminals 849 8WLI Registration/Release, Encryption Settings 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.

Annex A. WLAN(802.11b/DSSS) Specifications OfficeServ 500 Wireless LAN Service Manual/Ed.00 Annex A-4 © SAMSUNG Electronics Co., Ltd. 3.2 MAC Layer MAC layer supports both an ad-hoc network and a client/server infrastructure network. CSMA/CA are base on distributed coordination function(DCF) and uses random back off algorithm to prevent the layer from collide with other media. Point coordination function(PCF) is optional and is used for adjusting the priority of media. PCF enables access point to operate as point coordinator in basic service coverage areas and clients get priority. PCF is suitable for time-bounded services such as voice application. The details of CSMA/CA are as follows. Carrier Sense Multiple Access/Collision Avoidance (CSMA/CA) Standardized 802.11 uses CSMA to implement peer to peer as a basic connection way because CSMA expands the connection way of Ethernet(IEEE802.3) to wireless network. It is not easy to detect collision in CSMA unlike cable media. Since there is a station that fails to detect carriers within a section due to hidden terminals, A CSMA/CA with Ack way reserving transmittance time using RTS/CTS frame and returning Ack frame for checking transmittance is used. Since CSMA is based on Distribution Coordination Function(DCF), the time of gap(IFS) for sending CTS and Ack frames that operators do not want to disconnect to CSMA is supposed to be shorter than that of IFS for sending RTS or data frames. In addition, associated IFS should be used when an error occurs due to Point Coordination Function PCF) and interference in Access Point AP).
OfficeServ 500 Wireless LAN Service Manual/Ed.00 Annex A. WLAN(802.11b/DSSS) Specifications © SAMSUNG Electronics Co., Ltd. Annex A-5 3.3 Data Link/Network Layer The flexibility of network construction, a strength of wireless LAN is fully considered in IEEE802.11 and is expressed in network models. Network models defined in IEEE802.11 are categorized into an ad hoc network and Infra network. Ad Hoc Network The Ad hoc network consists of terminals only and is based on direct communication between terminals. Its operation is to be recognized by Zone ID called BSS ID logically. The Ad hoc network is suitable to collaborate through information sharing or networks using wireless LAN where networks are not equipped. Figure A.1 Data Link/Network Layer of WLAN-Ad hoc Network Model Infra Network Infra network is able to communicate with terminals that have at least one Access Point(AP) and are within areas other than the areas of Infra network. The models of the infra network has a Distribution System(DS), which serves as media. DS is an abstract concept and is included in network models. It distributes the definition of network as BSS ID. Specifications do not describe the implementation method of distribution. However, wireless LAN connected to the DS is called AP in the specifications. Management protocols that operate wireless LAN using infra network are defined in many ways. AP manages the operation of the zone and makes master and slave relationship among terminals in the zone. For this, AP sends beacon to the operating zone. It is impossible to send user data unless all terminals perform association to AP. Beacon and Association Beacon refers to sending code sending necessary information to wireless LAN. Association means that terminals are connected to one AP. User 1 User 2

Annex A. WLAN(802.11b/DSSS) Specifications OfficeServ 500 Wireless LAN Service Manual/Ed.00 Annex A-8 © SAMSUNG Electronics Co., Ltd. 5 Quality of Service (QoS) QoS refers to the capability of networks that reduces the traffic volume of networks or reserves some bandwidth. Network administrators provide their networks with QoS in many ways. QoS does not mean 100% assurance of bandwidth or 0 % of packet loss rate. However, QoS enables network administrators to send specific traffic much faster or reserve network bandwidth. Network administrators can manage the transmittance of traffic more efficiently than before. QoS is the capability of networks that meets the service level of a specific application of networks. The simplest QoS sends network traffic according to the priority of transmittance and prior traffic is transmitted first. 6 Security In wireless communication, data might leak or impersonation might be happen. Therefore, MAC sub-layer is using encryption. Many Access Point(AP) products have filtering function in the bridge or router of upper layer due to the MAC address of the station. According to IEEE802.11, encryption is made by combining 40 bits or 104 bits button generated by 24 bits key and RC4 algorithm of RSA at each station. This is called Wired Equivalent Privacy(WEP). IEEE802.11 indicates that WLAN might be decoded due to long interception because keys are fixed at stations. Therefore, the strict implementation of WEP is discussed in IEEE802.11i. IEEE discusses procedures for authentication on wireless LAN and Ethernet to prescribe them in IEEE802.1x standard.
