Chapter 1 Overview of the TimeProvider  
This chapter describes the TimeProvider product.  
In This Chapter

TimeProvider User’s Guide 19  
   
Chapter 1 Overview of the TimeProvider  
Overview  
Overview  
The TimeProvider is Synchronization Supply Unit (SSU) designed specifically to  
meet the needs at the network edge. In small offices where core office  
synchronization solutions are critical, an edge clock like the TimeProvider is ideal  
because of its compact size and flexibility. Using the integrated GPS features, you  
can use the TimeProvider in a “small” Central Office to act as a Primary Reference  
Source (PRS).  
The TimeProvider’s unique design incorporates the input, output, and clock  
functions in a single card, available with either a Rubidium or quartz oscillator. This  
allows you to simplify the storage inventory required for future expansion needs.  
The TimeProvider shelf requires only three plug-in cards to operate with full  
redundancy: dual Input/Output/Clock cards (IOCs) and a single Information  
Management Card (IMC), which serves as a communications/alarm interface.  
When dual IOCs are installed, you can mix any combination of Rubidium and quartz  
oscillators (for example, Rb/Rb, Rb/Qz, or Qz/Qz) to the needs of the network. The  
main shelf provides up to 32 redundant universal timing outputs; an optional  
Expansion Panel provides an additional 32 redundant outputs.  
Using Symmetricom’s SmartClock™ technology design, the oscillators within the  
IOCs are enhanced with improved performance and accuracy. Using intelligent  
firmware algorithms, SmartClock “learns” the effects of the ageing of the clock while  
it is locked to a reference signal and stores this information in its memory. If the  
reference signals are lost or disqualified, SmartClock uses the stored data to  
compensate for frequency changes while the TimeProvider continues to distribute  
highly stable synchronization signals.  
®
The TimeProvider also uses Symmetricom’s BesTime algorithm when the GPS  
input is activated. By using other inputs as references, Bestime calculates and  
determines a weighting factor for each of the inputs and ensembles them in the  
overall timing scheme to provide very accurate timing outputs. In the event of GPS  
signal loss, BesTime continues to predict GPS timing information to provide reliable  
system timing outputs and holdover performance, ensuring that system reliability is  
maintained. See BesTime, on page 43 for more information.  
Shelves  
The TimeProvider is available in two shelf models. Each shelf supports up to 32  
redundant output channels.  
The TimeProvider 1000 is a 175 mm tall ETSI shelf that meets the requirements  
of ETSI 300 119-4 January 1994. Figure 1-1 shows the TimeProvider 1000 shelf.  
The TimeProvider 1100 is a 130 mm tall rear-access shelf; indicators are on the  
front panel and connections are available on the rear panel. Figure 1-2 shows the  
front panel of the TimeProvider 1100.
