Spectracom Corporation Model 9283

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 9283 NetClock/GPS 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. The 9200 series offers enhanced reliability features, including ovenstabilized crystal oscillator (OCXO) and Rubidium oscillator backups to maintain the NetClock’s time standard if the time reference is lost. An optional dial-out modem provides additional backup 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) over LANs or WANs – anywhere on the planet.

The 9293 uses the Linux v2.6 operating system and features 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, two RS-232 serial ports, two RS-485 data bus ports, and IRIG B/E

AM/TTL. Frequency outputs of 1 PPS and 10 MHZ are also provided, as are alarm outputs and programmable timer outputs. 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’ enhanced security features, which can be enabled and disabled by the user, include Secure Shell (SSH), Secure Sockets Layer (SSL), Secure Copy Protocol (SCP), Secure

File Transfer Protocol (SFTP), 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.
