anidealCOsolutionforFTTxLastMileapplicationsofbroadbandaccessbyISPs,

telecoms and campuses.

Comprehensive and Advanced VDSL2 Configuration

For thebandwidthanddistanceofbroadbandaccess, theVDL-2420MVDSL2

IP DSLAM supports multiple selective VDSL2 profiles (8a, 8b, 8c, 8d, 12a, 12b,

17aand30a).TohelpprovidetheISPswith internetaccessservice indifferent

physical line installation environments, the VDL-2420M supports configurable

DPBO (DownstreamPowerBack-Off)andUPBO (UpstreamPowerBack-Off) to

adjust thedownstreamandupstreamtransmitpower levelsforserviceproviders

toreducetheinterferencebynearbywires.Furthermore, itcanbeconfiguredon

a per link basis for transmission mode, rate limitation and SNR (signal-to-noise)

margin. These advanced VDSL2 functionalities help service providers to adjust

the line performance to ensure the VDSL2 service cannot be impacted by other

xDSL services in the same binder group and build a stable and reliable IP DSLAM

solution.Alarm Port Power Jack

Delivering Highly-demanding Connectivity for ISPs/Triple Play Devices

As the demand for home broadband connections increases, the VDSL2 technology

is the next media to support the integration of home services and provides a

significant transmission speed faster than that of the current cable modem and

ADSL technology. The VDL-2420M applies the EoVDSL (Ethernet over VDSL) to

providingupto100Mbpsdownloadcapabilityandmakesthefollowingmulti-media

servicesmoreefficientonthelocalnetwork:

■IPTV/HDTV

■VoD(VideoonDemand)

■VoiceoverIP

■VideoConferencing/VideoPhone

■On-lineGaming

■InternetRadio/On-lineMusic

■Long-distanceEducation

TheVDL-2420Moffersanexcellentbandwidth tomeet therequirementsof the

triple play devices for home entertainment and communications

QoS Features Provided to Ensure Best Performance

The VDSL2 DSLAM contains robust QoS features such as port-based, 802.1p

priority and IP ToS/DSCP to ensure the best performance of its VoIP and video

streamtransmission,thusempoweringtheenterprisestotakefulladvantageofthe

limitednetworkresources.

Selectable VDSL2 Data Rate for Service Differentiation

Through the management interface, the administrator can control the data

transmission speed of each VDSL2 interface. Telecoms and ISPs can immediately

andremotelyupgrade/downgradebandwidthserviceupondifferentdemands.

Efficient Management

Tofurtherexpandthecurrentnetwork,PLANETVDL-2420Mprovidesconsole
