IMS Rackmount Systems: A Time and Frequency Synchronization Platform in a 19-Inch Rackmount Chassis
A Versatile and Modular Solution for Time and Frequency Synchronization Applications in a 19-Inch Housing
The new LANTIME IMS series is a field-upgradable and extremely flexible system that covers your synchronization needs—today and in the future.
An IMS base chassis includes a power supply, a receiver unit, a management
and NTP server module (LAN-CPU), as well as additional slots for input and output modules.
- LANTIME IMS - M1000: Four slots for expansion cards
- LANTIME IMS - M2000: Six slots for expansion cards
- LANTIME IMS - M3000 / M4000: Ten slots for expansion cards
Redundant power and receiver solutions are possible for the following models of our IMS series:
- LANTIME IMS - M1000: Two power supplies and two receivers
- LANTIME IMS - M2000: Up to three power supplies and two receivers
- LANTIME IMS - M3000 / M4000: Up to four power supplies and two receivers
The IMS base chassis offers the following slot types:
-
IMS-PSU: Power supply (high-efficiency redundant power supplies, AC and DC variants available for IMS systems)
-
IMS-CLK: Reference clock modules (redundant receiver solution available for IMS time server systems)
-
IMS-RSC: Required for redundancy switchover operation (M1000 / M3000)
-
IMS-CPU: Central processor module providing NTP / SNTP time synchronization and management and configuration interfaces
-
IMS-ESI: IMS-ESI: Reference inputs for 1-PPS, variable frequencies and E1/T1 framed and unframed signals
-
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 synchronization for hundreds and thousands of NTP clients. The LANTIME module supports the following protocols: IPv4, IPv6, NTP / SNTP (v2, v3, v4), 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).
Synchronization for 2G / 3G / 4G Base Stations and LTE Advanced Networks
The PTP implementation supports both ITU-T profiles: ITU-T G.8265.1 for frequency, and ITU-T G.8275.1 for frequency and phase. This enables accurate frequency and phase synchronization over packet networks for all network elements that require synchronization, including 2G / 3G / 4G base stations and LTE Advanced networks.
Scalable NTP Time Server System
All modules support hot-plugging and the modules can be configured via the central web interface (from the CPU module). An almost infinite number of combinations of input and output modules can be assembled to fulfill almost any synchronization task. The ease of expanding and upgrading the system with new modules ensures that the IMS systems scale effectively to your needs.
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 slots.
Front Panel
The front panels of the IMS devices incorporate the familiar 4x16-character LC display and the well-established LANTIME menu panel with 4 directional and 4 function buttons. This allows for simple and fast local configuration of the main parameters from the device itself. Hundreds of configuration options for the LANTIME CPU and the IMS input and output modules can be changed using the powerful web interface.

Overview: IMS Rackmount Systems
LANTIME M4000
The Meinberg LANTIME M4000 has been designed to fulfill the synchronization requirements of modern 4G/5G/LTE networks. It is capable to act as a Primary Reference Time Clock (PRTC) and, because of its unmatched flexibility, can be deployed in different scenarios. The modularity of the IMS platform (Intelligent Modular System) allows the M4000 to be configured for all areas of a mobile backhaul network: in the core, metro or access network areas.
LANTIME M3000
The M3000 chassis has four power supply slots, two clock module slots, a seamless switchover card slot, a CPU slot and ten slots for additional input and output modules. Adding a second clock module and the required RSC switch module will turn the M3000 into a fully redundant solution.
LANTIME M3000S
The IMS LANTIME M3000S can be installed in 19 inch racks as well as 21 inch racks (with an adapter). The reduced mounting depth of the S chassis enables you to mount the system in 300mm ETSI racks.
LANTIME M2000S
The LANTIME M2000S is a field-upgradeable and extremely flexible system that covers your synchronization needs - today and in the future. Upgrading to more outputs, new connector and signal types and protocols is easier than ever with Meinbergs Intelligent Modular Synchronization platform (IMS).
LANTIME M1000
The 1U chassis provides two power supply slots, optional two clock module slots, a CPU slot and four (three in case of a second reference clock) slots for additional input and output modules.
LANTIME M1000S
The compact 1RU form factor, the hotplugging and hotswapping capabilities and the large selection of different modules for input/output sync signals, network synchronization interfaces and clock modules with different GNSS/radio receiver and oscillator options offer an unmatched reliability, scalability and flexibility.
IMS - XHERb
External Holdover Expansion
PRS10 Rubidium Oscillator
The Meinberg XHERb chassis adds superior holdover performance to the Meinberg IMS time and frequency systems. It contains either one or two PRS10 Rubidium modules from Stanford Research and can be eqipped with dual power supplies for each Rubidium module.
IMS - MDU
Modular Distribution Unit
Meinberg MDU (Multi-Distribution Units) are the simplest and most convenient way to add more buffered timing signal outputs to your distribution rack. MDU systems enable multiplication of input signals coming from an external system such as a LANTIME or a GPS clock with, for example, PPS and 10MHz outputs to be expanded to a large number of output signals of the same type. The 3U / 19-inch MDU basic chassis can compose of a redundant power supply and can be equipped with one or two input modules to allow redundancy of the input signals.
