TimeSource 3100

Primary Reference Source for Public Network
Service Providers (T1)

TimeSource™ 3100 is a stand alone office Primary Reference Source (PRS) with integrated GPS receiver which meets ITU-T G.811 network performance requirements. The TimeSource 3100 provides undisturbed frequency and time 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 TimeSource 3100'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 300 meters from the office shelf, without amplifiers, using inexpensive thin coax cable. The TimeSource 3100 can be managed via Symmetricom's TimeScan element manager. The system is CE compliant and provides Sync Status Messaging (SSM).

Configuration Options
TimeSource 3100 comes standard with two E1/2.048 MHz outputs. Expansion configurations include eight additional E1/2.048 MHz outputs, eight composite clock outputs, two retimed outputs, or eight T1/E1/2.048 MHz outputs programmable on a per port basis.

Applications
The TimeSource 3100 system can be configured as a PRS to front-end an office SSU/SASE or as a stand alone PRS with 10 outputs for remote or small offices.
