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).
