DZS’ MXK intelligent terabit access concentrator reflects a clean-sheet approach to a truly scalable multi-service architecture that is designed to meet the rapidly evolving demands on access networks. The MXK is a full-featured Multi Service Access Platform enabling service providers to combine data, video and voice in one platform over a pure packet access network. MXK gives carriers the flexibility to cost-effectively deliver triple play services over existing facilities. The MXK VDSL2 48-port line card with vectoring and bonding for the MXK is a high-density high-bandwidth module for the MXK 819/823 and MXK 319 chassis.

DZS’ MXK VDSL2 48-port line card provides VDSL2 speeds, which include the ability to provide both symmetric and asymmetric bandwidth. The Broadcom-based MXK VDSL2 48-line card supports up to profile 17a, as well as ADSL2 fallback, link bonding and vectoring. The VDSL2 line card on the MXK also provides ADSL2+ compatibility, allowing service providers to provide both VDSL as well as ADSL service.
