NEBS Level 3 Certified Building Integrated Timing Supply
for Carrier Class Networks
The TimeHub™ 5500 is the next generation Building Integrated Timing Supply (BITS) designed for carrier class networks. TimeHub is an NGN ready platform designed to meet all traditional central office synchronization and timing requirements, and to provide next generation PackeTime™ solutions critical to advanced service offerings such as IPTV. Already deployed as the workhorse for major fiber deployments in North America, the TimeHub 5500 is the platform of choice for delivery of carrier class NTP required to assure high QoS delivery of NGN applications and content.
The TimeHub System
Explosive growth in telecommunication volume, especially in video and data, has led to new technologies and critical applications. Service providers are growing to meet this demand; as a result, the requirements for synchronization have changed dramatically. Symmetricom’s TimeHub 5500 is the next generation BITS. It is a modular, fully redundant timing distribution system that tracks incoming timing references and qualifies the signals against network timing standards. Then, it filters and distributes precise timing to all equipment in the central office.
The TimeHub main shelf provides up to 140 1+1 protected outputs. If more outputs are required, up to four expansion shelves can be connected to the main shelf, increasing the capacity to over 1,400 fully protected 1+1 ports per system.
TimeHub’s carrier class NTP cards provide unsurpassed accuracy, protection, and scalability to drive NGN applications. The flexible architecture allows for 1:1 protected NTP cards to be installed in any open main or expansion shelf output slot. NTP cards are locked to the TimeHub master clock, taking full advantage of PRS traceability, and redundant holdover protection.
Management and Alarm Collection
The TimeHub system provides a new dimension in management by integrating and monitoring the performance of legacy equipment. As an intelligent network element, TimeHub provides full visibility and manageability of all input and output ports and all cards on the main and expansion shelves. System parameters can be modified and controlled through any of its multiple interfaces—serial and Ethernet.
