Page 1-173.4.5 WBS24 (Basic) BlockThe block diagram of WBS24(Basic) and functions for each block are as follows.Figure 1.4 Block Diagram of WBS24 WBS24 (Basic)3.5 WIP-5000M3.5.1 OverviewThe WIP-5000M(Wireless IP-Phone Mobile type) is the wireless mobile phone thatallows a voice communication through IEEE 802.11b wireless LAN. As the wirelessIP phone, the voice data is compressed into a packet form(Voice over WLAN) tosatisfy the wireless LAN specifications and the data is transferred/received through IPnetwork. When moving between Access Points(WBS24), as well as between the dataterminals like laptop computers with wireless LAN card, the handover function issupplied. The major functions of WIP-5000M are described as follows :y Supports the wireless LAN specification of IEEE802.11b.y Supports the SIP protocols in order to support the VoIP.y Supports various voice codecs.(G.711, G.726, G.723, and G.729)y Provides the echo suppression function.y Supports the display service of incoming VMS-messages(Voice Mailing System).y Supports the message service provided from the phone of OfficeServ 500System.y The system upgrade can be done through the wireless LAN.Laptop computers, PDA and IP Phone, except the WIP-5000M, can use general-purpose equipment.WLAN NICCARD(802.11b)MAC/BB/Ext.Ant.ExternalAntenna- Diversity- Gain : 2dBi- DipolePCMCIAPowerController(3.3V/5V AutoSwitch)LEDControlEmbeddedCPU(NetARM Core *2)Flash ROM4M byteSDRAM16M byteVoltageRegularInput : 3.3VOutput : 1.8VVoltageRegularInput : 5VOutput : 3VAC/DC Adaptor(Local Power)AC220/DC+5VSIORS232CDC/DC Power(Remote)-48/+5, +3.325MHz XtaResetEthernet I/FEthernet10/100TRJ-45-48V 3.3V5.0V1.8V SDRAMBUS32bitsPCMCIA I/F(EPD)3.3V or 5.0V3.3VMagnetic
