INTRODUCTION (2)- BackgroundLegacy Network Characteristics…..
Lacks potentiality to incorporate current technological innovations
Limited service support:- traditional voice & data services
Parallel networks:- switched voice (TDM) & p2p narrowband data network (IP over TDM)
Multi-vendors proprietary systems:- difficult system integration, Inefficient management systems
Many obsolete systems (Switching, tx):- High Opex (ed) , deteriorated service quality, lack of spares, poor support from vendors due to ceased manufacturing

INTRODUCTION (3)
Industry Forces: • Obsoleteness of legacy technology• Technology shift: circuit-to-packet (IP) based platform• Convergence (buzzword): Network, Service, fixed/mobile)
Market Forces:• Meet Consumer new expectations:- new VAS, convergence, packaging,
convenience (portability & flexibility)• Competition:- gain an edge,
Regulatory Forces:• New framework encourages shift to new technology• Mandatory license obligations i.e phasing out of Manual exchanges, rural
coverage, USA etc
Drivers for network transformation

Objectives of Network TransformationProfitability ……
Cost to serve:- CAPEX and Opex• Cost optimization by
migrating network from PSTN to NGN
• Optimized performance: Control, management & service provision
Business growth - more revenue• New revenue streams from
value added services on NGN network

Approach……Gradual transformation (Keep & Grow):
Implementing gradual and scaled process by reasonably integrating new platform while keeping the legacy network components (i.e exchanges) to their useful lifetime.
To enable new network to co-exist with the legacy PSTN for a reasonable time period before fully migration to NGN.
Cost effective approach: leaves PSTN components to be removed gradually by replacing with the NGN/IMS compliant nodes on basis of their obsoleteness.
