General Product Description

The Trestles Time and Frequency System is a rackmount GPS Receiver designed for time and frequency applications including NTP and PTP network time server requirements. With 4 option module slots, and up to 4 user-configured outputs per module, Trestles is adaptable to many different applications. Option modules include our Universal Card, Code Output card, T1 module, Have Quick module, Low Phase Noise frequency card and fiber option input and output cards.

Time and rate outputs are precisely referenced to GPS or time code input. Two time codes are available simultaneously in both AM and DCLS formats on the Universal Card. Additional signals include pulse rates along with 1MHz, 5MHz and 10 MHz sinewave outputs.

Smart Port

Through the use of our Smart Port Technology, Trestles introduces a revolutionary way to distribute the above time codes, frequencies and pulse rates. A wide variety of signals are available in every ORCA Tech Trestles time and frequency system. Every user has front panel or web browser access to each of these ready-to-use signals that can be selected for distribution via optional rear panel modules providing up to 16 independent outputs. No longer do you have to dedicate a specific signal to a specific output—you can change them at any time. Smart Port Technology puts control into the hands of the customer and gives the ultimate amount of flexibility in supporting today’s ever-changing time and frequency requirements.

Network Security

Trestles utilizes the latest and greatest network and security practices available today. With security being of utmost importance to many of our customers, including government organizations and the military, Trestles was specifically designed to be the most secure Network Time Server available. Utilizing the latest OS and software available to us through our LINUX platform, ORCA is able to incorporate protocols specific to network security Information Assurance (IA) standards. ORCA understands the importance of making the latest protocols available to the end user while also taking into consideration JTIC and STIGS standards. Security will always be a standard feature on our product. Any new security features will always be incorporated into our latest software update, which will always be free of charge to our customers.

Suggested Pairing

This unit can be paired with our System Matrix Switch Distribution Amplifier SMS-101 or our SD-218 switch and distribution amplifier to provide ultimate flexibility in the number and variety of each output. Switching technology is included for redundant operation.

Trestles comes with a 2-year warranty. Technical support and software updates and upgrades are always free.
