7. Voice Network Migration Step by Step Approach
Transport / Optical Migration
The migration of the current transport network to the new optical network in preparation for vacating offices and migrating traffic to new service platforms
Network Database Migration
Traffic Migration
Signaling Migration
OS Migration / Synchronization

8. Voice Network Migration Step by Step Approach
Transport / Optical Migration
Network Database Migration
Enables the pre-provisioning of VoIP network elements by collecting data from the existing network and reformatting it through the use of a custom designed tool set to load into the VoIP elements.
Traffic Migration
Signaling Migration
OS Migration / Synchronization

9. Voice Network Migration Step by Step Approach
Transport / Optical Migration
Network Database Migration
Traffic Migration
Movement of traffic from the current switch to the Gateway Border Elements through the use of scripted DCS bridge and roll process or other migration techniques.
Signaling Migration
OS Migration / Synchronization

10. Voice Network Migration Step by Step Approach
Transport / Optical Migration
Network Database Migration
Traffic Migration
Signaling Migration
Enables migration of switched access trunks to the next generation VoIP Border Element, transparent to other interfacing Service Providers
OS Migration / Synchronization

11. Voice Network Migration Step by Step Approach
Transport / Optical Migration
Network Database Migration
Traffic Migration
Signaling Migration
OS Migration / Synchronization

Target Architecture Issues
Technical
Operational
Major Program Schedule Delays
Primary Source of Cost Overruns
Capital
Operating
Delays in New Service Introduction
Delayed Revenue
Customer Dissatisfaction
Caused by
Insufficient Attention to Transport, Network Database, Signaling/IN, OSS Migration
Lack of Coordination among Multiple Vendors
Inadequate Program Management
Operational Issues during Transition
Provisioning, Billing, Maintenance
OS Migration Must Account for Transitional Network
Dual Provisioning
Database Synchronization
Lost Revenue
Increased Operational Costs

14. Summary TDM – IP Migration is a move forward in technology.
A complete methodology and approach is vital to the success of the project.
Understanding the risks of the project will be important to the overall plans
A complete beginning to end plan is necessary to cover all areas.
