The Network Transformation Initiative
Network Operators are Transforming to all fiber networks
Eliminates aging copper plant
Cost Savings
Increased reliability
Improved resiliency to harsh environments
Quicker repair times
Revenue Generation
Opportunity for new high bandwidth, higher revenue generating services
Modernizes the network in preparation for IP-Centric deployments
Eliminate 40+ year old Switches, RTU fees, CO tech presence
Reduce, Reuse, MD’d Equipment Parts
Reduce OPEX, Real Estate Holdings, Property Tax

Why Collapse / Replace / Modernize – the Challenges
Lack of Support: No new parts are available; systems/equipment are Manufacture Discontinued and most of the OEMs are out of business
Lack of Expertise: As personnel retire, service providers are faced with significant cost to retain or develop technical support capabilities without the manufacturer’s support
Greater Liability: As systems near end of life, component and system failure rates increase
Increased Operational Expense: Relative to newer softswitch and IP solutions, Class 5 switches use significantly more power, HVAC and occupy more real-estate
Legacy Services Remain: Huge loss of traditional copper served lines leading to 50% or less capacity and still need to support that PON just can’t handle today
This initiative is a step forward but not a final, overall solution for complete TDM removal

5. Network Transformation
The Issues
There is no cost like a sunk cost with no additional revenue coming in
Service Providers are positioning to move to a network that is Ethernet / IP enabled
Logistical hurdles (i.e. copper & Class 5) are present that prevent complete migration to an IP switch environment
Legacy NEs do not provide for a seam-less transition or require that many legacy elements be left in place
Still require Emergency Standalone service for intraoffice calls to local emergency services
FCC has been looking at TDM sunset for sometime but with no real solutions to support funding
What other equipment can/should be replaced while modernizing the network?
Replacing platform MUST be able to support, POTS, Coin, ISDN, Ground Start, CLASS features, and many Special Service Circuits including xDSL

6. Network Transformation
Objectives / Quantifiable Benefits
Eliminate Class 5 Switches
Use for spare parts for MD’ed switches
Eliminate RTU fees, CO tech presence
Eliminate Legacy Transport Equipment
Migrating specials to D4s continues TDM deployment
Evolve to an IP / Ethernet Centric Network
Decouple voice switch upgrades from access network upgrades
