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
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) 1st phase of service provider subscriber offering Relatively mature market
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
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…

Insufficient MCPS in client device – additional external device (DSP) required
Increased device capability means VoIP is now a software-only function, using a fraction of the available processing power

Residential Voice Gateway Segment Trends IP Phone/Phone Adapter
Originally low featured; trend is now toward a complete voice feature set equal to that of RGW products (fax support, Supplementary Services, provisioning, etc…)
Interfacing to home routers in addition to BB modem where many customers already have deployed a home routing solution in advance of subscribing to VoIP
Residential Voice Gateway (RVG) Rapid movement toward WLAN solution for routing BOM cost continues to be the #1 driver for
development QOS becoming a more significant requirement Automated provisioning, billing, & support transparent
to end customer
VoWLAN (Wifi-phone) Trend is moving toward dual mode solution
