VoIP TECHNOLOGIES
IN RURAL AREAS
Bob Harvey
Regional Director, MetaSwitch
Spring VON – April 1, 2004
Slide 2
INTRODUCTIONS
• Bob Harvey• Regional Director, MetaSwitch
• MetaSwitch• A division of Data Connection• Financially stable for 22+ years• Established provider of communications
technology to• Service providers (SBC, Verizon, BT, …)• Vendors (Cisco, Lucent, Nortel, Siemens, …)
• VP3500 Next Generation Class 5 Switch• Proven Class 5 switch with rich set of subscriber
features for legacy replacement or cap & grow• Broadband (IP & ATM) and TDM interfaces today• Next gen services – IP Centrex, web self-care• 40+ deployments – about 50% with rural telcos
Slide 3
AGENDA
• Background – the rural service provider market
• Why Rural Service Providers are moving to VoIP
• Case studies• New Knoxville Telephone• Yukon Telephone
• Conclusion
Slide 4
THE RURAL SERVICE PROVIDER MARKET
• While urban areas are served by RBOCs, rural areas in the United States are typically served by independent telephone companies, often community-owned co-operatives
• There are more than 2,000 such independent operating companies (IOCs) in the United States• The 100 largest alone have >23M access lines• >50% of Class 5 switches serve <5,000 subscribers
• While some are conservative, many IOCs are on the leading edge of new technology like VoIP• High broadband availability• Many have co-operative ownership structure – so demand
new services is from members• Smaller organizations, so shorter decision-making process
Slide 5
WHY VOICE OVER IP FOR RURAL TELCOS?
• Growing recognition of cost savings of • Packet-based infrastructure – management & bandwidth
efficiency• Next generation class 5 switches – capital cost,
management, support, maintenance• … And threats to funding structure (USF, NECA) are
creating real cost consciousness
• USDA Rural Utilities Service starting to accept VoIPgear, e.g.• Occam Networks Broadband Loop Carrier• MetaSwitch VP3500 is first listed VoIP Class 5 Switch
• Competitive drivers
Slide 6
COMPETITION IN THE RURAL MARKET
• Broadband VoIP services are bringing competition to rural areas – in many cases for the first time
• Also, cost efficiencies of packet voice (e.g. 802.11 networks) enable much sparser competitive deployments to be profitable
• In response, independent telcos are looking to compete• New business / revenue generating opportunities• New services – video (and VoIP) over DSL, cable, fiber, …• New subscribers out of region – “edge-out” into the RBOC
town next door• Target high-end residential (triple-play) and small businesses
(IP Centrex)
Slide 7
EXISTING GR303-BASED ACCESS NETWORKS
• Traditional Digital Loop Carrier (DLC) terminates POTS and DSL, converts to TDM (T1/3, GR-303)• DLC and DSLAM may be separate or combined

VOIP AS A REPLACEMENT FOR GR-303
• Broadband Loop Carrier converts POTS to IP• Equipment available today• Requires an IP interface to the switch – ideal solution is a
next generation Class 5 switch with this capability on-board

CASE STUDY: NKTELCO – PROFILE
• Small rural-based ILEC/CLEC and cable company; CLEC arm is GoldStar Communications
• Current service offerings include:• POTS• Video and high speed data over the cable network
• Using Next-generation Class 5 Switch to thwart competition and increase revenues with out-of-region expansion
• Service offerings:• VoIP over cable• VoATM over T1 / ADSL• GR-303 for TDM voice
• Combining best use of existing TDM equipment and VoBB with a hybrid MetaSwitch VP3500 to target new services

CASE STUDY: YUKON TELEPHONE PROFILE
• Incumbent telephone provider to rural Alaskan communities of Whittier, Tanana and Ruby• <1,000 subscribers in incumbent area
• Goals• Migration strategy for legacy Class 5 switches• Consolidate switching to one location• Leverage lower costs of IP satellite• Leverage existing DSL and cable TV broadband networks• Use flexibility of IP access to expand service base (e.g. via
satellite and 802.11b wireless networks)
• Using MetaSwitch VP3500 configured for• GR-303 – to interface to existing DLCs• VoIP – for new services and circuit-to-packet migration

CONCLUSIONS
• The rural market is not a backwater – independent telcos are at the forefront of the VoIP tidal wave• Migration of existing legacy infrastructure• Competition and new services
• Next generation technology is available that fits the rural / independent market space• Circuit-to-packet migration – cost effective VoIP loop
carriers• Class 5 Softswitches with support for required legacy
features and new VoIP services
• … and it’s being deployed!• MetaSwitch >40 deployments, ~50% by independent telcos
