Prestige 871

DMT 3/4/5-band, IP-based VDSL Modem

VDSL, the fastest offering of DSL, provides

significantly higher bandwidth than other DSL

technologies. VDSL technology, which is similar to

that of ADSL, uses existing copper wires to deliver

high-speed data services.

The major issues with VDSL technology are the line

codes to be employed, which can be divided into

either single-carrier or multi-carrier modulation

schemes. For example, QAM is the most widely used

form of single carrier systems while DMT, the

standard line code for ADSL, is the primary form of

multi-carrier modulation. Both QAM- and DMT-

based systems can be designed for VDSL

applications. However, DMT modulation

dynamically adapts the bit rate to conditions on the

local loop and offers excellent performance even over

noisy lines.

To provide VDSL service to end users, Telcos in

different areas may have different deployment

strategies unique to their existing and future network

plans. Ethernet in the First Mile (EFM) is increasingly

being adopted by service providers and is being

evaluated by Telcos who have traditionally used ATM

networks in the past. Without the ATM layer,

networks become more cost-effective, flexible, and

efficient. The Prestige 871, which is built without

ATM, perfectly fits the network demands of today and

tomorrow.

ZyXEL's Prestige 871 DMT-based VDSL modem

supports a complete range of speeds ranging from

64Kbps to 25Mbps. Symmetric speeds for the Prestige

871 range up to 25Mbps at 64Kbps increments while

asymmetric speeds range up to 52Mbps downstream

and 26Mbps upstream at 64Kbps increments.

Benefits

DMT Modulation — Standard Compliance and Outstanding Performance

The Prestige 871 is a DMT (Discrete Multi-Tone)-based VDSL CPE. DMT

modulation dynamically adapts the bit rate to conditions on the local loop

and offers excellent performance even over noisy lines. Network

administrators become free from manually testing lines and from constantly

adjusting equipment to noise conditions. Both IEEE 802.3ah Ethernet in the

First Mile (EFM) Task Force and IEEE T1E1.4 Working Group selected DMT

as its worldwide VDSL line-coding standard.

Bandwidth of over 25 Mbps Per Port in Full Duplex

The high-bandwidth Prestige 871 allows service providers to simultaneously

deliver a variety of value-added services, such as broadband Internet access

and multiple streaming video channels. With the Prestige 871, small to

medium business users can have much higher bandwidth for both

symmetric and asymmetric applications while home users can enjoy

interactive media-rich entertainment which was previously unavailable.

Triple Play over Existing Copper Wires

With VDSL, traditional “copper wire” telecom operators may begin offering

“triple play” multimedia services such as multiple high-quality digital video

streams, high-speed internet access, and voice services in a way which

provides a user experience similar to today’s other existing distribution

systems (cable, terrestrial, satellite). New revenue can be generated with a

minimal amount of installation time and expense.

Co-existence with Plain Old Telephone Service (POTS), ISDN and Digital Phones

VDSL can be implemented quickly, even if there is only one phone line per

tenant. The existing POTS or ISDN services may be kept while adding new

broadband services.

Best CPE for EFM Applications

Due to Ethernet’s relatively low cost, simplicity, flexibility, ubiquity and

high bandwidth, there has recently been growing momentum in the use of

Ethernet in access networking. Such trends in access networking make the

Prestige 871 a perfect solution for EFM applications.
