TimeSource 3000 INTRODUCTION Symmetricom’s TimeSource® 3000 is a stand alone office Primary Reference Source (PRS) with integrated GPS receiver which meets GR2830 requirements. The TimeSource 3000 provides undisturbed Stratum 1 synchronization when locked to GPS with continued Stratum 1 performance for up to 72 hours upon loss of GPS. The key to the TimeSource 3000’s superior performance is its patented multiple input frequency locked loop BesTime™ clock engine. The BesTime engine, GPS receiver, and digitally controlled quartz local oscillator work together to produce precise timing outputs. Span line or remote oscillator inputs can be added, at the user’s option, to increase system reliability and holdover performance in the event GPS signals are interrupted. The GPS antenna can be installed up to 1,000 feet from the office shelf, without amplifiers, using inexpensive thin coax cable. The TimeSource 3000 can be managed using TL1 commands or via Symmetricom’s TimeScan® element manager. The system is NEBS certified and provides Sync Status Messaging (SSM). CONFIGURATION OPTIONS TimeSource 3000 comes standard with two T1 outputs. Expansion configurations includes eight additional T1 outputs, eight T1/composite clock outputs or eight T1/E1/2.048 MHz outputs programmable on a per port basis. KEY FEATURES • Innovative BesTime Clock Engine • IF Antenna Provides 1000 Foot Cable Run Without Amplifiers • GPS Holdover Accuracy of 1x10-11 for 72 Hours With Optional Inputs • Timing Accuracy of 100 ns When Locked to GPS • Sync Status Messaging • Integrated Sync Monitoring of Inputs • Optional SNTP TimeServer • Eight User-Configurable T1/Composite Clock/E1/2.048 MHz Outputs • NEBS Level 3 and Telecordia Certified APPLICATIONS The TimeSource 3000 system can be configured as a PRS to front-end, an office BITS or as a standalone PRS with 10 outputs for remote or small offices. In the standalone configuration, TimeSource 3000 provides multiple T1 and composite clock outputs in a compact, inexpensive package. This configuration is ideal for timing remote switch sites which may also have SONET terminals, digital loop carrier equipment, or channel banks. The TimeSource 3000 ensures PRS performance is maintained through self-auditing the inputs and measuring and reporting performance against one another. Inputs can be easily provisioned to be either included in the ensemble output or be used for monitoring only. The TimeSource 3000 is fully software upgradeable and provisionable while in-service. Communication is via RS-232 or Ethernet ports. TimeSource 3000 Primary Reference Source For Public Network Service Providers TELECOM SOLUTIONS
