ESI – External Synchronization Input
Menu "IO Config -> Input Configuration -> ESI - External Synchronization Interface"
The ESI (External Synchronization Input) card is capable of adding additional synchronization sources to an
IMS system. It accepts E1 and T1 sources as a Bitstream (2.048 MBit/s/1.544 Mbit/s, supporting SSM/BOC).
It also handles configurable frequencies (1 kHz - 20 MHz) and 1PPS pulse synchronization source, if re-
quired. 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.
