IP DSLAM Solution

Supporting versatile functions from CPE to IP DSLAM solutions, D-Link adequately satisfy ISPs’ requirements in ADSL/2/2+ broadband service deployments

Gigabit uplink and multicast support, D-Link IP DSLAM solution provides enhanced capability for triple-play application

Providing additional high value-added EMS central management system and versatile admin interface, D-Link intends to rapidly enter this field

D-Link IP DSLAM Solution

Now D-Link currently presents IP DSLAM solution to solve service providers’ triple play deployment demands in cost-effective and high value access network

DAS-3216 – 8/16 ports IP DSLAM compliant with ADSL standard

DAS-3224/3248 – 24/48 ports IP DSLAM with Gigabit uplink and compliant with ADSL/2/2+ standards

DAS-4192 – 192 ports ADSL2+ IPDSLAM

DAS-4672 – 472 ports ADSL2+ IPDSLAM

Why we need D-Link IP DSLAM Solution?

ISP investment protection by providing IGMP multicast solution to meet Triple-play demands in existing ADSL service

Supports 1000Base-T and fiber Gigabit uplink for eliminating traditional ATM E1/T1 expensive investments and accessing the broadband network further and quicker than before

Elastic remote ADSL service deployment by 16/24/48 complete ports solution supplement

Cost-effective and high-value central management capability for ISP by providing a Microsoft NT/SNMP based GUI EMS system

From CPE to IP DSLAM, seamlessly operates and integrates, D-Link provides service providers with a complete ADSL Service solution

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.

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
