DZS’ MXK intelligent terabit access concentrator reflects a clean-sheet approach to truly scalable multi-service architecture, designed to meet the rapidly evolving demands on access networks. The MXK is a full-featured Multi Service Access Platform enabling network service providers to combine data and video, as well as many other services, on one platform over a pure packet access network. MXK gives carriers the flexibility to cost-effectively deliver triple play services over existing facilities. The ADSL2+ line cards for the MXK are high density modules that provide very high speed non-blocking asymmetrical bandwidth for the MXK 819/823 and MXK 319 Chassis.

DZS’ ADSL2+ line cards for the MXK have 72 ports providing ADSL2+ speeds, which include the ability for higher upstream speeds (up to 3Mbps) using Annex M. The ADSL2+ line cards also support both Annex A and Annex B modes to support world wide deployment needs.

ADSL2+ Bonding is supported on this line card effectively doubling the available bandwidth to the subscriber. Bonding two ADSL lines together provides the opportunity to extend current subscriber services further from the central office. ADSL line bonding also provides more bandwidth for service subscribers looking to deploy high-revenue services such as IPTV.

DZS’ SLMS (Single Line Multi-Service) access operating system provides intelligent functionality across all the company’s hardware products. Driven by 8 years of experience in commercial operation and collaboration with 700+ service providers worldwide, DZS’ SLMS software delivers functionality critical to today’s access networks in advanced networking, quality of experience, security, and management.
