Central Offices

Equipment at service provider central offices (or cable MSO head ends) has two main functions: bandwidth distribution and allocation, and network management: control, provisioning, and maintenance. Scalable-performance and high-reliability are fundamental requirements, as are high-density/low-power to support thousands of subscribers.

Designed for access networks serving both business and residential subscribers, Teknovus’ OLT chips provide all the built-in functionality and performance required for delivering triple-play services.  For example, the Teknovus TK3723’s Turbo-EPON^TM MAC features a configurable Dynamic Bandwidth Algorithm (DBA) that supports hierarchical fairness for guaranteed Service Level Agreement (SLA) contracts. Fully configurable L2/L3/L4 line rate packet processing allows for advanced classification, filtering, and application monitoring.

To meet the needs of subscribers and carrier business models, real-world triple-play networks face the challenge of continuously delivering an endlessly-varying combination of bursty MPEG-compressed video, latency-sensitive VoIP calls, and Internet traffic. High-capacity traffic management and shaping in the central office/head-end are required to satisfy these requirements – yet may add many thousands of dollars in CapEx. The TK3723 has more than 2,000 shapers and supports up to 512MB of packet buffering – enabling 2-5 seconds of buffering per IPTV channel, while grooming network traffic to optimize utilization while maintaining guaranteed service levels.

Additionally, Teknovus is rolling out a comprehensive set of firmware and hardware features that enables service providers to add powerful network monitoring and fault diagnosis to both installed and new networks – at low cost and with no service impact. This functionality is only supported by Teknovus TK3723 OLT and TK3714/TK3715 ONU chips as well as Turbo-XPON (10G EPON) devices.

Teknovus’ Optical Monitoring offers two methods of detecting and isolating faults in the optical distribution network (ODN):
