Building Integrated Timing Supply (BITS) for high QoS delivery of NGN applications and content over carrier networks
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.
Designed to meet synchronization requirements for today’s demanding video and data applications, 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. It then filters and distributes precise timing to all equipment in the central office. Already deployed as the workhorse for major fiber deployments in North America, the TimeHub 5500 is the platform of choice for delivery of carrier grade Network Timing Protocol required to assure high QoS delivery of NGN applications and content.
The TimeHub 5500 main shelf provides up to 160 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.
Accuracy, Protection and Scalability for NGN Applications
TimeHubâ€™s carrier class NTP cards provide unsurpassed accuracy, protection, and scalability to drive NGN applications. Using advanced hardware-based time stamping to provide 10-nanosecond accuracy, the TimeHub 5500 provides accuracy orders of magnitude better than enterprise class NTP servers.
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.
