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

TOCFixed operators go for Service Bundling: Triple Play
Realising the full potential of xDSL Increasing the value of
ServicesAbility to offer a new range of services to the consumer

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
