TDM – IP Network Migration Program Scope

Deployment• Engineering & Installation• Integration & Optimization

Network Migration• Transport• Network Database• Signaling / IN• OSS Synchronization• Traffic

Office ConsolidationEquipment Removals

© Lucent Technologies 2005 - All Rights Reserved

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 MigrationStep by Step Approach

© Lucent Technologies 2005 - All Rights Reserved

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 MigrationStep by Step Approach

© Lucent Technologies 2005 - All Rights Reserved

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 MigrationStep 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 MigrationStep by Step Approach

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
