z500 Series Time Servers
ZTI Communications offers several NTP and PTP time servers with a wide range of operating temperatures in a compact and robust enclosure with different options described in the following table.
| Product | Protocol | Satellites | Application | Operating temperature | Power-over-Ethernet | Fast start without satellites (1) | Oscillator (2) |
|---|---|---|---|---|---|---|---|
| z504 | NTP | GPS | Static & Mobile | 0°C | +50°C | Option | No | TCXO |
| z505 | NTP | GPS | Static & Mobile | - 40°C | + 70°C | Option | Option | OCXOHR |
| z506 | NTP | GNSS | Static & Mobile | - 40°C | + 70°C | Option | Option | OCXOHR |
| z510 | NTP + PTP | GPS | Static | - 40°C | + 70°C | Option | No | OCXOHR |
Notes
(1) Fast start without satellites: with this feature the unit needs less than one minute to provide accurate timing information
(2) OCXOHR: OCXO High Resolution
These time servers are industrially proven and used in many countries for different types of civil and military applications: defence, aerospace, communication systems, data centers, financial networks, utilities, factory automation, security …

Option: Fast Start feature (z505 and z506 products)
With the “Fast Start” feature the unit needs less than 1 minute at power-up to provide accurate timing information. And if it has already GPS(GNSS) Almanac and Ephemeris loaded in memory, then it is fully operational in about 20 seconds.
Then it becomes possible to power-up the unit only a few minutes per day, to synchronize the different elements of your system.
To provide the time at power-up if no GPS (GNSS) signal is available (antenna disconnected or hidden inside a building for example) and if no synchronization is possible with other external time servers (private or public), the internal RTC with TCXO powered by internal lithium battery delivers time during at least 6 months (when power OFF), with 1ms to 100ms accuracy:
- max drift of ±4 minutes/Year with the temperature range -40°C to +70°C.
- max drift of ±1 minute/Year with the temperature range 0°C to +50°C.
