  • IMS-CLK: Up to two reference clock modules (redundant mode)
  • IMS-PWR: Up to two high efficiency redundant power supplies (AC and DC versions available)
  • IMS-CPU: Central processor module providing NTP / SNTP time synchronization and management and configuration interfaces
  • IMS-ESI: Input references for 2.048MHz, 2.048MBit/s and variable frequencies:
  • IMS-MRI: IRIG, 1PPS, 10MHz input module:
  • IMS-IO: A variety of output signals for all types of synchronization tasks:
    Pulses, frequencies, time codes, serial time messages) and of course more network interfaces (IEEE-1588, NTP/Management ports)

NTP Time Server for large Networks
With up to 25,000 NTP requests per second, the system is able to provide time for hundreds and thousands of NTP clients. The LANTIME module supports the following protocols: IPv4, IPv6, NTP / SNTP (v2, v3, v4), PRP (IEC 62439-3), HTTP (S), SSH, Telnet, SNMP (v1, v2, v3), FTP, SFTP, DHCP/DHCPv6. For each system, up to 99 logical network interfaces are available (99 IPv4 and 99 IPv6 addresses).

Scalable NTP Time Server System
All modules are hot-plug capable and the modules can be configured via the central web interface (from the CPU module). Almost infinite number of combinations of input and output modules are available to meet almost any synchronization task. Because of simple extension by upgrading the system with new modules the scalability of the M1000 system is ensured.

Slots for Input Signals:
IMS-MRI:Standard reference inputs
IMS-ESI: Extended reference inputs
Both of these reference input interfaces may also be used as I/O slot.

Front Panel
The front panel of LANTIME M1000 integrates the familiar LC-Display with 4x16 characters and the well known LANTIME menu panel with 4 directional and 4 function buttons. This allows for a simple and fast on-site configuration of the main parameters. Hundreds of configuration options for the LANTIME CPU and the IMS input and output modules can be changed using the powerful web interface.

The Active Cooling Module allows the installation of the M1000 safely within the temperature specification. The ACM is easily field-replaceable and allows for a hot-plug replacement without the need to power down the unit.

Reference OptionsThe following reference sources can be used to synchronize the system:
  • GPS - Global Positioning System
  • GLONASS - Russian GNSS
  • GALILEO - European GNSS
  • BeiDou - Chinese GNSS
  • PZF - German DCF77 longwave radio signal
  • PTP/IEEE1588 - Precision Time Protocol
