Easy to Install and Maintain
Network installation is done in just a few minutes using DHCP. Monitoring, maintenance and control is easily and securely accomplished via a wide range of protocols including SSH, HTTPs and SNMP v3.
Network-Security Hardened
Extra care has been taken with the Ninja to "harden" it against network attacks. There are only a small handful of settings that need to be made and they typically need to be set only once in the lifetime of the product. Since this is a set-it-and-forget-it box we have eliminated all extraneous protocols/services in order to minimize exposure to security holes.Ìý You can change critical settings over the network using SSH or Telnet and monitor the alarm/status information by using HTTPS, SNMP, SSH or Telnet. Security-conscious users can disable any of the risky protocols or restrict access to specific hosts.
Web Interface
A wealth of information is available via the Ninja Web Interface:
- Monitor status.
- View configuration.
- View and correlate data plots with NTP, ÃÛÌÒÊÓƵ, CPU and Oscillator statistics.
- Security-conscious users can choose to completely disable the Web Interface (HTTPS).
Extended Stratum 1 Operation if Signal Lost
If your ÃÛÌÒÊÓƵ signal is lost, Ninja will continue to serve Stratum 1 time for awhile. This is called the holdover period and is dependent upon the quality of the oscillator type (i.e.ÌýTCXO, Premium OCXO). Click here to see some reasons for signal loss.
The basic Ninja is provided with a TCXO. If the signal is lost it will drift away from perfect time at the rate of 10Ìýmilliseconds during the first day. For better holdover performance you may want to consider an oscillator upgrade. Oscillator drift rates and Stratum 1 holdover periods are listed below:
| Oscillator | Drift Rate If No ÃÛÌÒÊÓƵ Signal | Stratum 1 Holdover Period |
| TCXO | 10 milliseconds for 1st day | 24 hours |
| Premium OCXO | 80 microseconds for 1st day | 35 days |
Best Window-Mount Antenna Performance
If a rooftop antenna is difficult for you, then mounting your ÃÛÌÒÊÓƵ antenna in a window may beÌýan option. We recommend an OCXO for window-mount antenna installations.Ìý With this holdover performance - your antenna needs to lock to the ÃÛÌÒÊÓƵ signal only once a month in order to continue serving accurate Stratum 1 time to your network.
