Benefits
DMT Modulation- Standard Compliance and Outstanding Performance
ZyXEL P-872H 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. This eliminates manual line testing and reduces equipment adjustment to accommodate the noisy line condition. In addition, DMT is the selected VDSL line -coding standard by the IEEE 802.3ah Ethernet in the First Mile(EFM) Task Force and IEEE T1E1.4 Working Group .
150 Mbps Bandwidth Aggregated for Triple Play over Existing Copper Wires
With VDSL, telephone companies can offer triple play services (such as high-quality digital video streams, high-speed Internet access, and voice services) over existing cooper wiring. This allows them to offer the user experience similar to today’s other existing distribution systems (cable, terrestrial, satellite). Thus VDSL gives telephone companies the competitive edge while generating revenue with a minimal amount of installation time and expense.
Co-existence with Plain Old Telephone Service (POTS), ISDN and Digital Phones
VDSL can be deployed quickly, even if there is only one phone line per tenant. You can still keep existing POTS or ISDN services while adding new VDSL services.
QoS for Multiple Services Ensured
The bandwidth control feature with different class of services on the P-872H guarantees QoS based on multicast priority, 802.1p, TOS and DSCP.
