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