Transcript Challenges of Delivering Rural VoIP

Challenges of Delivering Rural VoIP
(SP-04)
 What is the compelling reason to offer VoIP?
 High cost of entry into VoIP..



Technical staff learning curves
Expected return on investment
Class 5 Legacy issues
 Poor voice quality & reliability of VoIP transport..


Access gateways, E-911, LNP, 1-800, Operator Services
Costs to upgrade network to provide expected high QoS broadband
access - what flavor DSL?
 Rapid technology evolution – life cycle?
Directions – Existing Telcos

Telcos’ core business shifts from POTS to IP services carried on ultra-broadband
PIPES…….POTS-To-PIPES (P2P)
 People moving off ‘wireline’ as a must have connection
• Cheaper LD with VoIP and Better mobility with cellular
Telecom Evolution for Rural VoIP





New signaling protocols will be more effective than existing AIN and
ubiquitous (SIP)
Corporate sponsors will pay for transport, offer free public phone calls
 listen to a 15 second message from the sponsor
IXCs role will change
 IP centric QoS transport, network management,
 Core network application service providers and LECs will prosper if IP
enabled
LECs will benefit by providing transport access and specialized applications
at the network edge.
 Local peer to peer switching,
Core applications for network intelligence;
 E911, routing, LIDB,
 Turnkey solutions available for Rural Telcos

• Regional traffic stays in region
• Avoids backhauling
• LD routed to maximize profitability
• Ability to maintain Access/Termination fees
• Backhauled cost reduced via IP
• Local Gateway Utilized for pure LD

Trends in Long Distance Voice Transport

Voice over Internet becoming extremely inexpensive means to transport voice
and data..
 Long distance commoditized, charges becoming inconsequential…or zero
 Commercialization of voice transport, “free ride”
• Sponsors pay for transport
• Users pay for access.


New DWDM technologies will continue to keep supply of transport high and
prices low.
 Bandwidth expanding rapidly
 Inherent QoS improvements for VoIP
Innovative applications leveraging embedded intelligence in IP and PSTN
gateways..
 Applications readily customizable for specific client needs
 Pay as you go for specialized access and features / utility
 Video conferencing will lead way to Video over IP
 But, Do not overlook Basic Engineering Requirements

Other Rural VoIP Challenges
 1) VoIP results in bypass of access/termination fees

Use existing CLASS 5 and TDM Carrier terminations
 2) 911 service to VoIP subscribers must be provided


Configure system to use existing PSAP connections
Outsource E911 management available for VoIP
 3) DSL speeds are a big factor in VoIP quality



Low speeds in the 120kbps range do not support VoIP protocols that take up to
100kbps
VoIP can be compressed to a lower quality 33kbps
SIP based DLC/DSL can also solve VoIP bandwidth issues, and reduce OAMP and
backhaul costs
 4) Rural carriers must deal with TDM, ATM and IP networks


Operational cost of technical resources, infrastructure components & test/diagnostic
equipment
Consider solutions that evolve to a pure IP network infrastructure
 5) PSTN subscribers are dropping in the USA



VoIP dial tone service includes CLASS and V/M features @ 1/3rd the Price
Cellular services can be bundled w/PSTN and VoIP to attract users
New SIP enabled “sticky” services retain customers
Compelling Reasons to deliver VoIP
 Competitive offering to prevent subscribers from changing service to
“Vonage” type, IM type, VoIP
 Access to IP- LD networks for reduced operating costs, and customer
retention..
 Supply and Demand – Economics of high supply of IP bandwidth
 Technology obsolescence – VoIP will reduce overall value of legacy
transport systems to basic commodity.
 Relocation of network intelligence to the core and edges of the network
to provide revenue generating applications.
 Potential “Sticky” services
