IMS-ESI
2.048MHz, 2.048MBit/s, 1PPS and Variable Frequency Input Card
ESI – Extended Reference Input
The ESI (External Synchronisation Input) card is capable of adding additional Synchronisation 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 – 20 MHz) and a 1PPS pulse Synchronisation 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.
