12/16

1. No support from Vendors of Legacy Equipment (EoS and EuL)

2. Maintaining service parity of the legacy services with the NGN while pushing for new and advance NGNfeatures and services

a. Emulation and Simulation of complex PSTN legacy services in NGN (PRI/BRI, E1 R2, etc.)

3. Interworking with Legacy Equipmenta. Corporate Legacy CPEsb. Leased line Services

4. Protection of Investment on Existing Facilitiesa. Substantial investments on copper (OSP facilities) which are designed mostly for voiceb. Substantial presence of legacy CPEs notably for enterprise and business costumers

5. Re-designing of the network to address the Last Mile limited bandwidth

6. Implementation of end-to-end Network Security and QoS

7. Modification of Existing Processes to adopt to NGNa. Fault Restorationsb. Subscriber and Service Provisioning

8. Upgrade of Existing Backend Networka. Billing System - to support the NGN extended/complex CDR formatb. Provisioning System to automate subscriber activation and service modificationc. Bandwidth Management to effectively monitor and allocate bandwidth

9. Enhancement of Existing Competency/Skills Build (should now be more IP Centric)

10.Regulatory issues on NGN network interconnectiona. establishment of additional new interconnection

11.Decommissioning and Environment Friendly Disposal


13/16

1. Managing market readiness and acceptance to the NGN technology shift

2. Business viability of going full NGN

3. Up sell customers to new Next Generation services

4. Managing customer experience at time of implementation cut-over

5. Managing affordable Cost of Bandwidth

6. Predatory Pricing

7. Requires Government support in broadband deployment in rural areas (tax incentives)


14/16

1. Most Philippine Telcos started to migrate to NGN. Implementation will be on a phasedapproach. Full NGN migration is estimated to happen by:

For Major Telcos: beyond 2012

For Other Telcos: 2012 or earlier

2. Factors needed for full NGN Migration:

Technology Maturity

Actual Subscriber Needs

Cost Benefits

3. Age of equipment being replaced are 10 years or higher

EWSD, 5ESS, S12, DMS100, F150, AXE10&150, etc.

4. NGN Migration program is being done with two or more Vendors.
