Voice Network Migration
Step by Step Approach
1. 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
2. Network Database Migration
3. Traffic Migration
4. Signaling Migration
5. OS Migration / Synchronization

Voice Network Migration
Step by Step Approach
1. Transport / Optical Migration
2. 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.
3. Traffic Migration
4. Signaling Migration
5. OS Migration / Synchronization

Voice Network Migration
Step by Step Approach
1. Transport / Optical Migration
2. Network Database Migration
3. 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.
4. Signaling Migration
5. OS Migration / Synchronization

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

Voice Network Migration
Step by Step Approach
1. Transport / Optical Migration
2. Network Database Migration
3. Traffic Migration
4. Signaling Migration
5. OS Migration / Synchronization
•
Accelerates migration through automated updates of
OSS Databases in synchronization with network
element traffic migration

Program Risks
 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
 Customer Dissatisfaction
 Lost Revenue
 Increased Operational Costs

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.
