Overview

IMS CPU Modules: Management and NTP Processor 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.
IMS Network Modules: LAN-CPU, TSU – IEEE-1588, LNE GbE:

LNE: Network Expansion – additional network interfaces TSU-GbE: PTP / SyncE / Hardware NTP Interface
IMS Receiver Modules: GPS / Glonass Satellie Receiver, Signal Switch Unit:

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. In case of a complete loss of all external synchronization sources, the clock module will enter hold-over mode and allows the output modules to continue to work for a certain amount of time.
Each IMS system requires at least one clock module and can be turned into a redundant solution by adding a second clock module and a signal changeover unit such as the RSC.

The available clock modules always come with an integrated receiver for external GNSS/radio signals and accept a large selection of other synchronization sources like pulses, frequencies, time codes and serial time strings when combined with either an MRI or ESI card.

IMS Input Modules: Reference Input Signals:

MRI: 10MHz, PPS, IRIG, TC-AM / TC-DCLS reference signals ESI: Input module for 2.048MHz, 2.048MBit/s and variable frequencies TSU-GbE: PTP / SyncE / Hardware NTP Interface
IMS Output Modules: Configurable and fixed Outputs:

User-selectable combination of IMS I/O modules 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 Telecom Modules: LIU Line Interface Unit:

Telecom Synchronization Signal Card (E1/T1 framed/unframed).
The ideal output card for telecom applications, offering 2.048MHz/1.544MHz G.703 75 Ohm unbalanced and 120 Ohm balanced frequency outputs as well as BITS 2.048Mbps or 1.544Mbps framed outputs with full SSM/BOC support, both as 75 Ohm unbalanced and 120 Ohm balanced. It is possible to order the LIU card with front panels with multiple combinations of these outputs.

IMS Power Supplies: IMS Power Modules:

Power supplies in various voltage ranges for our modular systems
For our modular systems we offer power supplies with AC and DC power. Any power supply can be used in redundant mode and they are hot-swappable in operating mode.

Meinberg´s IMS power supplies have been custom made with high efficiency in mind, the two models currently available support either 100-240 V AC or 20-72 V DC and it is possible to populate the PWR slots with an arbitrary combination of both AC and DC power supplies.
