IMS – Modules

Power Supplies, Input Signals and Output Signals for Meinberg IMS – Systems

All I/O slots (MRI, ESI and I/O) support any combination of I/O output modules. The selection of already available IMS output modules provides a stunning selection of output signals, but will be expanded in the future to add more signals and physical interfaces as needed.

IMS CPU Modules

As the central management hub, the CPU module is another core element of our IMS systems. It runs the management and configuration interfaces and is also responsible for alarm notifications and status information. The LTOS V6 firmware platform offers a feature rich newly designed web UI as well as a powerful SNMP management interface for a perfect integration of the IMS device into your central network management system.
CPU-C05F1: Management and NTP Processor Module
As the central management and control element, the CPU module in an IMS system is responsible for management, configuration and alarm notifications. It additionally provides NTP and SNTP services on its network interfaces. The IMS-CPU model C05F1 comes with one integrated 10/100base-T port, additional network ports can be added by installing LNE cards.

IMS Clock Modules

The GPS and GPS/GLONASS clock modules are the central synchronization elements in an IMS system. The internal clock carries a highly stable oscillator that is utilized to generate the base synchronization signals which are distributed to all I/O module slots via the backplane.

IMS GPS: GPS Satellite Receiver
The frequency locking of the master oscillator to the GPS-system enables this module to generate fixed and programmable standard frequencies with high accuracy and stability. Various oscillator options allow the cost efficient implementation of different requirements concerning the accurracy of the outputs.

IMS GLN: Clock Module with combined GPS/GLONASS Satellite Receiver
Central clock module for the Meinberg IMS platform. The GPS/GLONASS receiver can use an externally connected antenna to receive both GPS and GLONASS satellite signals, decode them and use them as a reference source for the integrated, oscillator-based hardware clock. In addition to synchronizing with the GPS/GLONASS satellite system, the IMS-GLN clock module accepts a wide range on input references when combined with IMS input cards (MRS – Multi Reference Source).

IMS PZF: PZF (DCF77) Correlation Receiver (Eurocard)
High accuracy DCF77 correlation receiver for generation of standard frequencies and pulses

IMS RSC: Switch Module for Seamless Switchover of Backplane Signals
This module is required for redundant clock module configurations and switches the synchronization signals from the selected clock module to the IMS backplane (most I/O modules use these backplane signals to generate their output signals). A new feature offers a phase neutral switchover for LIU output cards, avoiding phase jumps for telecommunication signals (E1/T1). The RSC can be configured to automatically switch between the two clock modules based on their status but it is also possible to manually select the clock module using the selection switches.

IMS Input Modules

MRI: 10MHz, PPS, IRIG, TC-AM / TC-DCLS reference signals
If an application requires to use external synchronization sources instead of radio/GNSS signals, an MRI card enables the installed clock module to synchronize to 1PPS, 10MHz, DCLS and AM time codes (IRIG B, AFNOR, IEEE1344 or C37.118).

ESI: Input module for 2.048MHz, 2.048MBit/s and variable frequencies
The ESI (External Synchronization Input) card is capable of adding additional synchronization sources to an IMS system. It accepts E1 and T1 sources, both as a Bitstream (2.048MBit/s/1.544Mbit/s, supporting SSM/BOC) or Frequency (2.048MHz/1.544MHz). It also handles a configurable frequency (1 kHz – 10 MHz) and a 1PPS pulse synchronization source, if required. An ESI card is, as the MRI card, dedicated to one specific clock module (depending on the slot it is installed in) and can be installed in both ESI as well as MRI slots.
