Business Drivers
Cost effective migration
Switched circuit to packet-based networks
Open standardised layered NGN/IMS/SDP
architecture
Reduction in CAPEX/OPEX investment
Coexists with existing legacy
PSTN/ISDN Emulation (PES)
PSTN/ISDN Simulation (PSS)
Fully integrated T-IMS and Service Delivery
Platforms (SDPs)
T-IMS/SDP must enable Telkom to become
a Broadband Multimedia centric company
Offer rich communications services creating
new innovative revenue opportunities
