IMS Telecom Modules: E1 / T1 Signal Generators

Telecom Synchronization Signal Card (E1/T1 framed/unframed)

The ideal output card for telecom applications, offering 2048 kHz (ITU-T G.703) -- 75 Ohm unbalanced and 120 Ohm balanced frequency outputs as well as BITS 2048 kBit/s or 1544 kBit/s framed outputs with full SSM/BOC support, both as 75 Ohm unbalanced and 120 Ohm balanced. It is possible to order a LIU card with front panels with multiple combinations of these outputs.

Overview: IMS Telecom Modules

IMS-ESI

ESI - Extended Reference Input
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 (2.048 MBit/s / 1.544 Mbit/s, supporting SSM/BOC) or Frequency (2.048 MHz / 1.544 MHz).

It also handles a configurable frequency (1 kHz - 20 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.

IMS-HPS100

High Precision Synchronization
The new generation of the Meinberg time stamping unit provides a future-proof platform for your IEEE 1588 / SyncE / Carrier Grade NTP infrastructure. The high-performance dual-core processor, the 1-step master clock and the 1GE interface with SFP slot supports a very large number of PTP clients.

IMS-LIU

Generation of reference clocks for synchronisation tasks
The module LIU (Line Interface Unit) generates different reference clock pulses which are derived from the GNSS-locked master oscillator of a preconnected satellite receiver. The output signals are available with high accuracy and stability therefore.

IMS-LSG

Generation of Reference Signals for Synchronisation Tasks The module LSG (Line Signal Generator) generates different reference signals (Clock/BITS) which are derived from the GNSS-locked master oscillator of a preconnected satellite receiver.
