Applications

The OSA 5225 v2 Time Node is important everywhere precise time is critic.

  • Autonomous, independent synchronisation of TCP/IP networks to UTC
  • Precise, UTC-traceable time stamping of e-business transactions
  • Precise time stamping of alarms, to reconstruct exact sequence of events
  • Synchronisation of telecom switches, for precise UTC-traceable billing

The OSA 5225 v2 Time Node is a precise time centre fea-turing two configurable synchronization inputs for redun-dancy and several outputs. The OSA 5225 v2 can be con-figured as a secure and redundant NTP Time Server as well as a time distributor of many other time protocol and format (IRIG-B, PPS, ...)

Technical Information

Input/outputs flexibility
Dual external synchronization can be chosen among GPS, NTP, IRIG-B/AFNOR NFS 87500 1000 Hz or DCLS signals. Up to 4 NTP ports are available. 3 NTP ports can be indi-vidually substituted with any synchronization outputs such as IRIG-B, PPS, ASCII, 10MHz sine wave, … All phase locked to the reference clock and individually configurable in offset and time zone.

High Accuracy
Its own base time and its synchronization algorithm guarantee and output accuracy of up to 100 nanoseconds when GPS synchronized.

Enhanced Security
High security level: 64 bits RSATM MD5 encryption, leap time protection, high stability time base, SNMP v3 alarm traps, static relay alarms, supervision with HTTPS and front display.

Power
The OSA 5225 v2 Time Node has a dual power supply 230/115VAC and 20-60VDC, allowing redundancy in case of power supply failure. The internal NI-Mh battery en-sures at least 2-hour of running reserve in case of main cut.

Management
Set-up and configuration can be done via Ethernet (telnet or http). Thanks to the SNMP module, an automatic alarm management is provided for the whole input/outputs of the NTP server. A general alarm on relays is also available.
