  • 8 configurable BNC outputs
  • UTC-derived 1PPS
  • ITU-T G.812 (I, V, VI) compliant holdover
  • Remotely (TCP/IP) and Locally (RS-232) Manageable

Applications

  • Mobile telecommunication networks
  • SDH/SONET transport networks
  • Base stations
  • ATM, LAN/MAN/WAN and Utilities
  • DAB and DVB broadcasting systems

The OSA 5230 offers combined GLONASS and GPS signal reception to supply highly reliable synchronization clock from the two world’s largest Global Navigation Satellite System (GNSS); the renowned Global Positioning System (GPS) and the promising Russian Federation’s GLObal'naya NAvigatsionnaya Sputnikovaya Sistema or GLObal NAvigation Satellite System (GLONASS).

The OSA 5230 GLONASS+GPS is a solution designed for the synchronization of several applications such as 2G, 2.5G, 3G and 4G mobile telecommunications networks, SDH/SONET transport networks, ATM, LAN/WAN, DAB/DVB, utilities as well as synchronization source for UMTS, WCDMA,

Technical Information

The OSA 5230 supplies synchronization on 8 outputs individually configurable, as below:

  • 2.048 Mbit/s (E1) compliant with ITU-T G.703-9
  • 2.048 MHz compliant with ITU-T G.703-13
  • 1 PPS, phase-locked to UTC
  • 10 MHz, phase-locked to UTC

When locked, the OSA 5230 regenerates the reference and attenuates jitter and wander. When no valid GPS and/or GLONASS reference input is available, the OSA 5230 enters in hold-over mode and holds its output frequencies to supply long hours of frequency and phase accuracies.

The OSA 5230 is also fully locally (RS-232) and remotely (TCP/IP) manageable thanks to its user-friendly Configuration Manager software. Furthermore, the OSA 5230 is very reliable and totally maintenance-free.
