modernization
Decide modernization option for each
region
Maximize capex expenditures where
needed
Maintain and expand the existing
technology
Upgrade legacy transport to second
generation
Upgrade network with open networking
technology

Well Defined Integration Approach Saves Time and Money
Network are generally comprised of
multi-vendor equipment
Operational subsystems sit on top : OSS
must be part of ecosystem
Management systems need to interlink
for efficient operations
Integration is at network and operational
levels
Core network changes limit some
migration activities
Pre-migration activities may be required
to get needed space and power
Fujitsu Proprietary and Confidential All Rights Reserved, ©2017 Fujitsu Network Communications15
Removing Risk from Integration
Leads to Seamless Connections and Quick Network Modernization Rollout
Use hybrid solutions
Engage industry experts
Do commissioning testing
HOW TO DO IT
Fujitsu Proprietary and Confidential All Rights Reserved, ©2017 Fujitsu Network Communications16
Deployment
Appoint project manager to control overall deployment
Define work-flow process map for delivery models
Understand critical path items
Establish delivery timelines and hardware lead times
Be ready for in-field changes
Define change order procedures, triggers and approval
processes
Create work orders, job completion and payments
Having a Detailed Plan and Single Point of Contact Leads to Success

An Example of DCS Migration
Network Modernization Dramatically Reduced Equipment in Central Office

13 bays of equipment removed, including DCS
