CHAPTER 1
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.
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.
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 3. Installation |
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.

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.
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 |
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.
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.
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.
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.
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.

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.
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.
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. If a data message(signal) is received, it is transmitted to LAN.)
Provides the compression and decompression of PCM voice data.

3.3.3Interface
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.
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.
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.
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.
