Microchip TimeHub5500 Level 3 Certified Building Integrated Timing Supply for Carrier-Grade Networks

Overview

Time Hub® 5500 is an NGN-ready platform designed to meet all traditional central office synchronization and timing requirements and to provide next-generation Packed Time® solutions critical to advanced service offerings such as IPTV. Designed to meet synchronization requirements for today's demanding video and data applications, Microsemi’s Time Hub 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 Time Hub 5500 is the platform of choice for the delivery of carrier-grade Network Timing Protocol required to assure high QoS delivery of NGN applications and content.

Output Capacity

The Time Hub 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.

Integration with Legacy Equipment

To ensure that legacy BITS meet carrier-class standards for reliability and compatibility with existing central office equipment, Time Hub 5500 delivers the ability to monitor multiple inputs and conduct performance measurements of existing local and remote BITS or any DS1 line. Up to eight DS1 and one 5 or 10 MHz inputs can be monitored simultaneously and their results sent to the NOC.

Smart Clock Technology Delivers Superior Synchronization and Timing

Using intelligent firmware algorithms, SmartClock® "learns"  the effects of aging and temperature on the clock while it is locked to the reference signal and stores this information. When the incoming reference signals are lost or disqualified, SmartClock uses the stored data to compensate for frequency changes during holdover. The system will continue to distribute highly stable synchronization signals while predicting and correcting the behavior of the oscillators until input reference signals are restored.

Protected Outputs for Uninterrupted Service

TimeHub 5500 1+1 is a truly hitless protection scheme in which both output cards remain active. If a card fails or is removed, the mate card is already providing a signal to the network elements. No time is lost waiting for a stand-by card to recognize a failure before it becomes active. The result is a clean, hitless timing signal no other protection scheme can offer.

Management and Alarm Collection

As an intelligent network element, TimeHub 5500 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.

Information

Brand:  Microchip

Part Number:  TimeHub5500

Type:  Timing Supply

 

Monitoring Inputs

The ability to monitor multiple inputs allows performance measurement of existing local and remote BITS or any DS1 line. Up to eight DS1 and one 5 or 10 MHz inputs can be monitored simultaneously and their results sent to the NOC. This helps ensure that legacy  BITS meet carrier-grade standards for reliability and compatibility with existing central office equipment.

Input and Clock Cards

The Input and Clock cards are combined in a single card with a highly stable clock engine. Each card accepts four DS1 inputs and one selectable 5 or 10 MHz input, plus four additional DS1 inputs for monitoring purposes only. The cards are available in either rubidium or quartz versions. The Stratum 2 and Stratum 3E clocks exceed the minimum specification requirements during the holdover
