SPECTRACOM NETCLOCK 9489 NetClock Time Precision GPS NTP Server USEDModel 9489 can track up to twelve GPS satellites simultaneously, providing highly accurate timing by synchronizing to the satellites' atomic clocks. A variety of time codes on multiple ports are included to meet the requirements of numerous systems.
• Stratum 1 NTP v2, v3, v4 Time Server
• Precision GPS time reference
• Peering and stratum 2 (up to 15) via NTP servers
• High bandwidth NTP performance
• Synchronizes security systems, computers, network elements (including PLC’s, IED’s,
telemetry systems), specialty devices, display clocks
• Meets regulatory compliance standards: Sarbanes-Oxley, HIPAA, Gramm-Leach-Bliley, OATS
• Supports internal audits including: audit trails, time-stamped records, log files, data archiving
• Web-based user interface
• IPv4/IPv6 dual stack
• Supports centralized user authentication (LDAP, RADIUS) and logging (Syslog)
• Remote diagnostics, flash upgrades, configuration, and control over secure communication
link
• Security features: SSL, SNMP v3, SSH, SCP, SFTP
• Alert notifications via SNMP Traps and directed e-mail alertTechnical Accuracy (when locked to GPS)
• 1PPS output ±50 nanoseconds of UTC
• RS-485: Time code ±100 microseconds to ±1 millisecond of
UTC, format dependent
• Ethernet NTP: Output jitter within ±50 microseconds relative to
UTC typical

Management
• IPv4/IPv6: Dual stack
• DHCPv4/DHCPv6 (AUTOCONF)/SLAAC: Automatic IP
address assignment
• Authentication: LDAP, RADIUS, TACACS+
• Syslog: Logging
• SNMP: Supports v1, v2, v2c, and v3 (no auth/auth/priv) with
Enterprise MIB
Communications
• HTTP: Browser-based configuration and monitoring
• Telnet: Remote configuration
• FTP Server: Access to files (logs, etc.)
• SMTP: Email
Security Features
• Enable/block protocols
• Set SNMP community names and network access
• Password protected
• Encryption: DES, AES
• Authentication: SHA, MD5
• SSL Web Based Interface: Web UI uses SSL to allow the
use of the secure HTTPS protocol to access configuration
and status web pages.
• SSH: utilizes SSL and data compression technologies
to provide a secure and efficient means to control,
communicate with, and transfer data to or from the master
clock remotely.
• SCP: is used to securely transfer files to and from the time
server over an SSH session.
• SFTP: is an FTP replacement that operates over an
encrypted SSH transport.
• SNMPv3 (no auth/auth/priv): allows remote configuration
and management over an encrypted connection.
• Alert notifications via SNMP Traps and e-mail
