TimeSource 3500

GPS Through the Window/Wall/Roof Stratum 1
Timing System (T1)

TimeSource™ 3500 is a stand alone Stratum 1 Primary Reference Source (PRS) which works in GPS hostile environments. TimeSource 3500 meets GR 2830 network PRS performance requirements by using a GPS antenna mounted inside a window or on an outside wall. Timing outputs with Stratum 1 performance are achieved using advanced BesTime™ technology, single-satellite locking GPS receiver subsystem, and Rubidium local oscillator.

BesTime is a flexible clock engine which provides robust performance in compromised GPS installations. BesTime continues to predict GPS timing information during the loss of GPS signals thereby guaranteeing Stratum 1 performance with as few as one satellite in view for as little as 10 hours per day. PRS quality holdover is extended up to three weeks for long term GPS outages. TimeSource 3500 can be installed in just about any window or outside wall with a view to the sky.

Configuration Options TimeSource 3500 comes standard with two T1 outputs. Expansion configurations include eight additional T1 outputs, eight composite clocks outputs or eight T1/E1/2.048 MHz outputs programmable on a per port basis.

Applications
The TimeSource 3500 system can be configured as a PRS to front-end an office BITS or as a stand alone PRS with 10 outputs for remote or small offices.
