Symmetricom, Inc. announces its carrier class, high performance NTP plug-in server card supporting QoS for next generation applications such as IPTV, Billing Record Management, QoS Measurement Systems and IP Service Level Agreements (SLA) monitoring. The carrier class NTP server card is fully integrated into the company’s TimeHub Building Integrated Timing Supply (BITS) system. NTP cards can be installed as single servers or redundant pairs in any available master or expansion shelf output slot. Already in large scale deployment, the TimeHub 5500 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.
