Residential VoIP Product Segmentation Current Market Segmentation for Residential VoIP End Points IP Phones/Phone Adapters (Terminal Adapters): Basic interface device converting analog phone traffic to IP based traffic; a voice only device with no data capability Residential Voice Gateway (RVG): Standalone voice appliance converting analog phone traffic to IP based traffic AND data routing for home PC connectivity in a single device Integrated Access Device (IAD): Integrated voice/data/broadband modem solution collapsed into a single standalone unit VoWLAN (Wifi-phone) Integrated voice/data/broadband modem solution collapsed into a single standalone unit
6
IP Phones/TAs Key Features IP Phones/Phone Adapters (Terminal Adapters): 1 to 2 RJ11 ports for phone termination 1 Ethernet port for interfacing to Broadband Modem or router Supplementary Service Support SIP Telephony only features Low-End Solution Optimized for low cost Complete voice feature requirements but no data features Key Features Voice Processing: G711, G729ab, G723.1, Echo Cancellation, Tone processing, T.38 fax, etc SIP protocol, provisioning Typical Positioning Lowest cost device for IP residential telephony (ignoring the PC only, peer to peer services) 1 st phase of service provider subscriber offering Relatively mature market
7
Residential Voice Gateway Key Features Residential Voice Gateway (RVG): 2 RJ11 ports for phone termination 2 Ethernet ports: 1 for interfacing to Broadband Modem, 1 for PC or router Supplementary Service Support SIP Telephony Data (Routing/Firewall/NAT) WLAN option Multiple Ethernet ports WAN connection to an external cable or DSL modem Single or multiple LAN connections direct to PCs or to home router WLAN AP Option Key Features Voice Processing: G711, G729ab, G723.1, Echo Cancellation, Tone processing, T.38 fax, etc SIP protocol Service Provider provisioning Data/Voice routing, firewall, NAT, DHCP, etc. Typical Positioning Low cost device for IP residential telephony Largest segment of current RGW market deployment with rapid growth Routing/Data features require networking and voice expertise Service providers quickly moving to WLAN solutions
8
Integrated Access Devices Key Features Integrated Access Devices (IAD): 2 FXS ports for phone termination 1 Ethernet port for PC or router DSL or Cable modem interface for WAN Supplementary Service Support SIP Telephony Data (Routing/Firewall/NAT) Broadband Modem functionality WLAN option WAN/Broadband Access Integrated cable or DSL modem LAN Ethernet Interface Single or multiple wired ports Optional wireless access point Key Features Voice Processing: G711, G729ab, G723.1, G729e and G728 for PacketCable, Echo Cancellation, Tone processing, T.38 fax, etc SIP or MGCP protocol MSO/Service Provider provisioning Optional voice/data routing Typical Positioning New Broadband subscriber deployment Driven by cable companies and DSL service providers Routing/Data features require networking and voice expertise Service providers quickly moving to WLAN solutions

VoWLAN Phone Key Features VoWLAN (Wifi-phone): Low-cost phone which utilizes the WLAN and VoIP infrastructure – not a GSM/CDMA handset or cellular-WLAN combo phone Significant market interest in potential applications mobility for traditional vertical markets mobility for enterprise desktop and residential / DECT or cordless phone replacement Solutions in the market today are limited (Spectralink, Symbol), proprietary and expensive – limited to niche vertical markets Significant barriers to adoption exist: cost must be comparable to DECT / cordless phones low power consumption – minimum 4 hour talk time, 80 hour stand-by time Standards – 802.11e (EDCF), 802.11i (WEP, TKIP, AES) Targeted integrated silicon solutions are needed – Broadcom, Agere, TI, etc … SpectraLink
