19.2.8 Analog digital conversion module, with time synchronization
(ADM)
19.2.8.1 Introduction
The Analog/Digital module has twelve analog inputs, 2 PC-MIP slots and 1 PMC slot.
The PC-MIP slot is used for PC-MIP cards and the PMC slot for PMC cards according
to table
694 . The OEM card should always be mounted on the ADM board. The UBM
connects the ADM to the transformer input module (TRM).
