No Impact to Existing Networks
To Existing NGN Networks:
A functional module addition to the existing SoftSwitch and backend application
Able to use the existing NGN for call processing and routing
Normal NGN users are still served by existing infrastructure
Zero impact of the FS addition
All (home/visiting) FMC users will be served by the FMC-FS
Registration, authentication, roaming, call processing, handover
FMC-FS requires access to FMC user profile data
HSS (Home Subscriber Server) model of IMS
To Existing GSM Networks:
GSM Homed FMC users appear to be regular GSM users
NGN Homed FMC users appear to be visiting GSM users
FMC-FS uses standard roaming Interface to the GSM Network

PSTN to NGN Migration Case Study
Background
A leading tier 1 carrier in Philippine
Owning 2m fixed & 22m GSM mobile customers as of Q2 2006
A public company listed in NYSE
Total market cap of US$7.8B as of Sept 2006
Total revenue US$2.5B in last 4 quarters
EBITDA US$1.6B in last 4 quarters
Operating margin 37%
A fast growing service provider in Asia
Provides fixed line, GSM mobile and broadband data service to both residential and enterprise
customers
Problem Statement
How to sustain and grow the fixed line service?
Lots of population without telephone service
Lots of business users demand more service
How to increase the ARPU leveraging NGN/IMS?
IPTV? FMC? Triple-play? Quadrupled-Play?
How to lower the OPEX?
Real estate expense in the big metropolitan area?
Power consumption?
Human resource required for operation?
How to manage EOL/EOS of the aged TDM switches?
The cost of maintaining is unbalance with the cost of buying new

UTStarcom Solution
PSTN Emulation Subsystem – PES
Provide services to green-field customers
Replace the existing TDM switch – total 7 models in place
mSwitch as the core
SoftSwitch + Gateways + Backend office applications
iAN8000 as the access
Combination of DSL, DLC and VoIP AG
Foundation for FMC and IPTV in the future
Phase 1: Started with 150K NGN lines capacity
Network installation and migration planning for 3 months
First TDM switch replacement/migration in March 2006
Adding customer via both old switch migration and green
field expansion
Service extension to Centrex
Targeting under served enterprise customers
Phase 2: Network expansion to total of 500K NGN lines
Contract signed in later 2006
Network fully deployed
Phase 3: Planning for total of 1.5M NGN lines in 2008
Total 5m NGN lines planned in next 3 – 5 years
150+ CO sites replaced by 3 NGN SS sites

Greatest Experience: Cut-Over
Procedure
IP, NGN, and PSTN inter-connect infrastructure configured and tested
AGs installed, wired on MDF, configured, and qualified
Migration of Digital Loop Carriers
Retrofitting the access gateways in existing DLC cabinet
Consolidation of cabinet areas
Sample subscriber data populated, provision ADSL Sub
Number migration set up and tested for lines and trunks
Bulk sub data migrated and tested again for all features and billing
MDF- isolation pin switched so that sub lines are switched from legacy
switch to AGs (a couple of minutes)
PSTN tandem switches re-route traffic from legacy switch to NGN C4 (1
minute)
