1 General Information
Spectracom Corporation is a leading manufacturer of precise time-keeping devices used to
synchronize critical operations. Our products provide accurate, reliable, Legally Traceable
Time™ across your networks. The Spectracom 9200 series NetClock™ is a direct response to
customer needs for affordable time synchronization equipment that includes a variety of
necessary and widely used security, authentication, and networking features.
1.1 Introduction
The Model 9289 NetClock/NTP Network Time Provider time server provides disciplined timing
using Network Time Protocol (NTP). The NetClock meets or exceeds the National Emergency
Numbers Association (NENA) master clock standard and is ideally suited for delivering world-
wide, split-second timing to mission critical systems. An optional dial-out modem provides
additional back-up to GPS and can function as the primary reference if desired.
Spectracom NetClocks are based on Global Positioning System (GPS) technology – tracking up
to twelve satellites simultaneously and synchronized to their atomic clocks. This enables
NetClock-equipped computer networks to synchronize all elements of network hardware and
software (including system logs) to the millisecond over LANs or WANs – anywhere on the
planet.
The 9289 uses the Linux v2.6 operating system and a high-speed processor. A variety of time
code outputs are included to meet the requirements of numerous systems, including a 10/100
Base-T LAN port, up to two RS-232 serial ports, and up to two RS-485 data bus ports. Alarm
outputs and programmable timer outputs are also provided. The NetClock allows users to
accurately time stamp video surveillance systems, access points, card readers, time clocks, and
alarm systems to provide necessary evidence and validation of events.
The 9200 series’ new standard security features, which can be enabled and disabled by the
user, include Secure Shell (SSH), Secure Copy Protocol (SCP), and Secure File Transfer
Protocol (SFTP). Enhanced security features include Secure Sockets Layer (SSL) and SNMP
v1, v2, and v3 with host access restriction. The NetClock supports IPv4, IPv6, and centralized
user authentication (LDAP/Active Directory, RADIUS). NTP capabilities include peering,
Stratum 2, and Autokey.
The NetClock can be configured and its reports accessed through a Web User Interface (Web
UI). A Command Line Interface (CLI) is also provided for initial product configuration through
the serial setup port. Once configured, the NetClock can be accessed, under appropriate
security policies, anywhere within a network. The product features browser-based remote
diagnostics and control as well as Flash memory for remote software upgrades. A 10/100 Mbps
Ethernet LAN port provides support for Network Time Protocol (NTP) over a variety of platforms,
including Windows 2003, 2000, and XP, Cisco, UNIX, Linux, and more. Remote control and
monitoring can also be performed through SNMP and Telnet.
The NetClock also includes a GPS antenna and ancillary hardware.
