Features

  • Dual IEEE 1588-2008 (v2) ports
  • Powerful PTP engine
  • Protected Gigabit Ethernet Electrical and Optical (SFP) ports
  • GPS / GLONASS input source
  • Frequency, Phase and/or Time-of-day auxiliary inputs and outputs
  • ±100 ns timing accuracy when locked to GNSS
  • Highly stable internal Quartz or Rubidium* oscillator
  • Compact 19'' or ETSI / 1U / 240 mm rack mountable chassis

Applications

Typical applications are the synchronization of

  • 2G, 3G, LTE, CDMA2000
  • WiMAX
  • DAB, DVB and DTV
  • Ethernet Backhaul
  • Passive Optical Networks (PON)
  • Circuit Emulation Services
  • Electrical Power Utilities

 

PTP allows the distribution of accurate frequency, phase and time-of-day to these applications even in cases where the transport network is asynchronous.

Precision Time Protocol (PTP) IEEE 15888-2008 (v2) is a solution for the distribution of synchronization over IP-based packet networks such as IP, IP/MPLS, Ethernet, IP/xPON and IP/xDSL networks.

Oscilloquartz offers a comprehensive range of PTP products covering all synchronization needs in the telecommunication, broadcast and power and utilities domains.

The OSA 5331 PTP Grandmaster is designed to serve reli-able time, phase and frequency to numerous PTP Slaves thanks to its dual PTP ports along with a powerful PTP engine.

The OSA 5331 PTP Grandmaster consists mainly of a GNSS-receiver (GPS + GLONASS) and a PTP engine de-livering PTP service over an Ethernet port along with fre-quency, phase and time-of-day outputs for legacy equip-ments.

To guarantee maximum protection or to operate without GPS antenna installation, the OSA 5331 PTP Grandmaster can be synchronized using frequency inputs such as 10 MHz, 2.048 MHz or E1 as well as 1PPS + ToD.

The OSA 5331 PTP Grandmaster uses an internal Quartz Crystal or Rubidium* oscillator as a highly stable time base.

The use of such precision oscillator options provides im-proved stability in holdover mode when the input source is interrupted for any reason.

The front panel has a large alphanumeric LCD, status indicator and 5-segment button for easy status and minimal configuration. The main configuration and monitoring is through a secondary network port providing web access.

So-called PTP Profiles are used to configure those parameters which are crucial for the interoperability with the connected slaves.
