DATA SHEET ® TimeSource 3000 Primary Reference Source For Telecommunications Network Operators ® ® The Symmetricom TimeSource 3000 is Configuration Options Key Features a stand alone office Primary Reference The TimeSource 3000 comes standard with • Innovative BesTime clock engine Source (PRS) with integrated GPS receiver two T1 outputs. It can expand with up to • IF antenna provides 1000 foot cable which meets GR2830 requirements. The eight T1/composite clock outputs or eight run without amplifiers TimeSource 3000 provides undisturbed T1/E1/2.048 MHz outputs programmable on -11 • GPS holdover accuracy of 1x10 Stratum 1 synchronization when locked to a per port basis. for 72 hours with optional inputs GPS with continued Stratum 1 performance • Timing accuracy of 100 ns when Applications locked to GPS for up to 72 hours upon loss of GPS. The TimeSource 3000 system can be • Sync status messaging The key to the TimeSource 3000’s superior configured as a PRS to front-end an office • Integrated sync monitoring of inputs performance is its patented multiple BITS or as a standalone PRS with 10 • Optional SNTP TimeServer ® input frequency locked loop BesTime • NEBS Level 3 and Telecordia Certified outputs for remote or small offices. In the clock engine. The BesTime engine, GPS standalone configuration, TimeSource 3000 Key Benefits receiver, and digitally controlled quartz provides multiple T1 and composite clock • Compliant traceable GPS with advanced local oscillator work together to produce outputs in a compact, inexpensive package. holdover capabilities precise timing outputs. Span line or remote This configuration is ideal for timing remote • Flexible programmable outputs oscillator inputs can be added, at the user’s switch sites which may also have SONET option, to increase system reliability and terminals, digital loop carrier equipment, holdover performance in the event GPS or channel banks. signals are interrupted. The TimeSource 3000 ensures PRS The GPS antenna can be installed up to performance is maintained through self- 1,000 feet from the office shelf, without auditing the inputs and measuring and amplifiers, using inexpensive thin coax reporting performance against one another. cable. The TimeSource 3000 can be Inputs can be easily provisioned to be either managed using TL1 commands or via included in the ensemble output or be used ® Symmetricom’s TimeScan element for monitoring only. The TimeSource 3000 is manager. The system is NEBS certified and fully software upgradeable and provisionable provides Sync Status Messaging (SSM). while in-service. Communication is via RS-232 or Ethernet ports.
