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.
