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 . 

 

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. 

 

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.
