Prestige 861 Series

Benefits

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.

ZyXEL’s Prestige 861 series, which is a DMT-based

VDSL modem, supports a complete range of speeds

ranging from 64Kbps to 25Mbps. Symmetric speeds

for the Prestige 861 series range up to 25Mbps at

64Kbps increments while asymmetric speeds range

up to 52Mbps downstream and 26Mbps upstream at

64Kbps increments. The built-in 4-port switch

allows multiple devices to share the bandwidth

without the cost of additional network hardware.

DMT Modulation — Standard Compliance and Outstanding Performance

The Prestige 861 series 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 861 series 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 861

series, 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.

An Instant LAN with an Integrated 10/100Mbps Switch

The combination of a switch makes the Prestige 861 series more efficient

and less expensive than a similar unit with an external switch or hub. The

industry-standard HP Auto MDI/MDIX features enable automatic and

transparent detection as well as automatic correction of cables. Product

installation, debugging, and network maintenance become substantially

easier and significantly more efficient.

VLAN Supports QoS for Service Differentiation

The VLAN feature in the Prestige 861 series offers the benefits of both

security and performance. For example, various priorities can be assigned to

differentiate real-time applications and Internet access applications via

VLAN tagging. Such control enables service providers to turn on various

broadband services to a larger number of customers more quickly and

economically.
