OSA 5225B Time Node Easily configurable with its outputs and dual synchronization inputs TELECOM NETWORKS POWER & UTILITIES TIME & FREQUENCY TIME DISTRIBUTION Highlights Multiple synchronization inputs & outputs The OSA 5225B Time Node is a precise time center featuring two configurable synchronization inputs for redundancy and several outputs. The OSA 5225B can be configured as a secure and redundant NTP Time Server as well as a time distributor of many other time protocols and formats (IRIG-B, PPS, ...). Plug and Play installation 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 individually 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. Secure Ethernet Supervision & Configuration 19’’ 1U aluminum rack case Alphanumeric display Redundant 20-60 VDC and 230/115 VAC power supply inputs and two hours of battery autonomy Applications Air transport, airports Rail transport, railway stations 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. Underground train Maritime transport The OSA 5225B 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 ensures at least 2-hours of running reserve in case of main cut. Power stations Businesses, banks and schools Hospitals and emergency services Fire stations Aircraft, trains and helicopters 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 all inputs/outputs of the NTP server. A general alarm on relays is also available.
