Multicasting Optimizes

Bandwidth Utilization

The IGMP proxy/snooping features offered in the

ZyXEL IP DSLAM family only forwards traffic to

subscribers requesting the specified multicast traffic.

This prevents unnecessary forwarding of multicast

traffic to all end points (including non-subscribers)

and thus freeing up bandwidth for bandwidth-

hungry applications, such as video streaming.

VLAN for Segmented Class

of Service and Sercuirty

By implementing VLAN (Virtual LAN) on the ZyXEL's

IP DSLAM, service providers are able to segment

different class of services easily. Each Permanent

Virtual Circuit (PVC) transformed to and from an

ATM-based CPE can be configured and mapped to

an assigned VLAN with different packet priorities.

Thus, service providers can differentiate the class of

services for Internet, VoIP and Video streaming. In

addition, VLAN on IP DSLAM also allows service

providers to provide network privacy and security to

B2B networks.

Complete DSLAM Family

For Different Deployment

Applications

Support Multiple Standards

for Different DSL Ranges

and Speeds

All ZyXEL's IP DSLAM models offer G.SHDSL/G.SHDSL.bis

and ADSL/ADSL2+ technologies in last mile

applications. Speeds range from 128 Kbps up to 24

Mbps and the loop-reach can extend up to 6 km. In

addition, the IES-5000 series provides the advanced

VDSL2 technology to support up to 100Mbps

downstream and 45Mbps upstream speed. By providing

access services using existing Ethernet infrastructure,

ZyXEL IP DSLAM series reduces installation cost and

allows broadband service providers to maximize

Average Revenue Per User (ARPU).

End-to-end Management

Minimizes the Operation

Cost

Besides basic configuration, fault, security and

performance management, NetAtlas Access EMS also

provides powerful and advanced remote

management capabilities to help service providers

minimize everyday operating costs. The loop-back

design helps isolate network problems, while new

firmware and IP DSLAM configuration allow changes

to be done remotely, eliminating the need for "truck

rolls" in order to provision new customers or

reconfigure services for existing customers.

All ZyXEL's IP DSLAMs use MSC1000 (Management

Switching Card) for uplink and subtending purposes.

MSC1000 comes with four Gigabit Ethernet

interfaces for easy deployment in a ring or tree

topology. ZyXEL provides a wide range of copper or

optical transceivers on the uplink and subtending

interfaces for applications of various distances and

media.

ZyXEL's IP DSLAM series offers a broad range of

options for every deployment environement and

scale. Available models range from an affordable 8-

port mini DSLAMs to versatile medium-size DSLAMs,

or 384-port modular DSLAM for large-scale

deployments. Two power inputs are available: the DC

version for central and remote office sites, and the

AC version commonly used for in-building

applications. In addition, selected models are

designed to comply with industrial standards for

being placed in a street cabinet to maximize

deployment opportunities.
