Why the 7302 ISAM?

Why a Multi-Service IP DSLAM

3

TOCBB Multi-Services is happening today

Attract more subscribers by offering more services Increased business opportunities

by offering services to both residential and business customers

Increased average revenue per user by offering existing customers access to value-added

services Increased total revenues

by increasing penetration and attracting new customers

Retain and grow of existing customer base Assuring end-to-end quality of service. Providing new services

TOCImpact on Fixed Access of Multiservice evolution

Multi-service from the same access platform is key

Increasing need for bandwidth, resulting in New BB access technologies (Multi-ADSL, VDSL, FTTU) Deep fiber & remotes deployment Increased capacity in the DSLAM

Access Network architecture evolving to IP Multi-Edge & Ethernet Migration engaged with hybrid ATM/Giga Ethernet aggregation DHCP is the end-game for VoIP, Video set top boxes, PPP remains for HSIA Service enabled edge, ensuring security & guaranteed QOS

Central Office Access platform becomes also an Intelligent Multi-service hub

Centralized subscriber & access management IP empowered (e.g. native multicast, IGMP proxy) Optical Ethernet termination
