LEDI® NETWORK ITS v2m 2U High Accuracy secure time Server with triple synchronization redundant inputs and with multiple synchronization outputs. Key features Internal time base Its incorporated battery and its oscillator allow to provide stable time code output in case of synchronization or power supply failure. Three quartz oscillators at choice : • OCXO LN: High frequency stability 5.10-10 (-10°C to 60°C). Low ageing 3.10-10 / day. • OCXO: High frequency stability 1.10-9 (-20°C to 70°C). Low ageing 5.10-10 / day. • TCXO: Frequency stability 1.10-6 (0°C to 60°C). Ageing 2.10-9 / day. Security Back up power is included by default. Possibility of extended back up power capacity with Option J. The duration of power reserve will depend on the configuration of the time server, please contact our sales team for more details. Backup configuration settings in flash memory. High level of security: 64 bits RSA™ MD5 signature, HTTPS. Supervision possible via SNMP software (Version 3). Network Protocols • • • • • • • • • NTP (v2, v3, v4) NTP Client/Server, Broadcast, Multicast SNTP (v4) HTTPS SNMP (v1, v2c, v3) IPv4 / IPv6. (DHCP v4 / v6 compatible) FTP SYSLOG PTPv2 IEEE 1588 Configuration Remote configuration and time setting via web interface. (secured connexion via HTTPS available) Time zone configuration. Automatic adjustment of Daylight saving. Supervision Information available via HTTP/ HTTPS, SNMPv3, Telnet, “GT Network Manager”, “GT Ethernet Supervision”. Time and synchronisation status is available on the alphanumerical front display. Operating on Windows NT/XP/2000/2003/Vista (32 bits)/ Windows7 Firmware update via FTP. 1 NTP output (RJ45) is included in the basic configuration. ® Synchronization Inputs • Specifications 18-36 VDC 36-72 VDC CE, EN 60950 (safety), EN 55022 (EMC transmission), EN 55024 (EMC immunity) 20 VA (depending on selected configuration) 31 Power Supply 115-230 VAC/50-60Hz Certifications Max. consumption IP Power Supply Redundancy 18-36 or 36-72 VDC with 115-230 VAC. Configurable priorities of synchronization inputs. Compensation of input delay due to transmission distance and threshold setting for security. Time Base and algorithm ensuring output accuracy up to 50ns when synchronized to GNSS. Multiple synchronization outputs of different types de time code. Time can be configured individually on each output, via DST and Offset. PPS and 10Mhz output (available with OCXO oscillator only) via BNC connectors. Alarm management via SNMP TRAP and two static relay outputs on screw terminal for synchronization and power supply alarms. Manual or automatic adjustment for transmission delay. System Event Journal.
