Remote Operation
Symmetricom’s TimeVault is an advanced time server that provides trusted, accurate time
from multiple time sources over an Ethernet connection to multiple client sites. One of
TimeVault’s great strengths is its remote control capability. You can configure
parameters through command line input using Telnet from a distant terminal, or use
TimeVault’s web interface to program the unit over the Internet, from anywhere in the
world.
TimeVault reports time with extreme accuracy, using GPS as a synchronization source.
Optimization for time functionality means that accurate position readouts are not
available.
3.1 Web Access
The main feature of TimeVault’s web interface is its ability to perform setup and control
operations from a remote location, using the Internet or TCP/IP LAN. The protocol used
is either Telnet or HTTP. Telnet is a standard Internet communications program that is
bundled with Windows 95/98/NT and connects to TimeVault through its NET Port.
HTTP access is provided via any standard Web Browser (such as Microsoft’s Internet
Explorer or Netscape’s Navigator/Communicator).
You can also disable remote control capability and secure TimeVault from a remote
location, (see “F100 LOCK – Remote Lockout” on page 4-76). However, once you have
issued this command, you can
not remotely unlock the unit. You can only unlock the unit
from the keypad.
3.1.1 Starting the Web Browser
To use the web interface, launch any Java-capable and frames-compatible web browser
such as Microsoft Internet Explorer (IE version 3.0 or later, available at
www.microsoft.com), Netscape Navigator (version 3.0 or later) or Netscape
Communicator (any version; Netscape browsers are available at www.netscape.com).
You do not need a web connection for normal TimeVault operation.
