9. Difference Between ATM & IP DSLAM Solution
ATM DSLAM
Huge investment
ATM infrastructure is only for telecommunications carrier usage.
Connection Oriented – Cost of OAM (Operation, Administration & Maintenance) is huge and difficult to achieve.
Not suitable for Multicast application
Most of applications are based upon IP
IP DSLAM
Packet prioritization, bandwidth management, and good QoS for Real-time application
Performance monitoring and providing statistics Information for Billing.
Supporting security control.
Network Element Level Management for central management.
Multicast application for Video/Audio broadcasting.

10. Opportunities of IP DSLAM
More additional features for data processing & management
Security enhancement by VLAN
Quality of Service
Multiple classes of service
Traffic management
Authentication/Accounting/Authorize (AAA)
VPN support
