This listing is for one (1) Time Source 3000 by Symmetricom
Comes complete with Manual, Cable and CD
TimeSourceâ„¢ 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. Upon loss of GPS, continued Stratum 1 performance can be maintained for up to 72 hours with optional inputs.
The key to the TimeSource 3000's superior performance is its patented multiple input frequency locked loop BesTimeâ„¢ 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 compliant and provides Sync Status Messaging (SSM).
In the standalone configuration, TimeSource 3000 provides multiple T1 and composite clock outputs in a compact, inexpensive package.
This was pulled from a working environment and is in excellent condition.
- GPS-based system meets Stratum 1 primary reference source (PRS) requirements;
- Proprietary BesTime(TM) technology enables PRS-quality at costs well below competitive solutions;
- Fully NEBS-compliant successor to company's widely-deployed DCD-LPR.
Symmetricom’s TimeSource 3000 is a stand along office Primary Reference Source (PRS) with integrated GPS receiver. It meets GR2830 requirements. It 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, GPA receiver, and digitally controlled quartz local oscillator work together to produce precise timing output.
Configuration Options: TimeSource 3000 comes standard with two T1 outputs.
Applications: The TimeSource 3000 system can be configured as a PRS to front-end, and 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.
