The MRC PC-25003 (232-620.0007) is a trunk board used in shipboard automatic telephone systems, which sit within the vessel’s marine control and communications installation. Built as a trunk PCB and marked N1103, it provides the trunk circuit section of the exchange hardware. Internal telephones link the wheelhouse, machinery spaces, steering gear room and crew areas, and the exchange depends on each of its boards to keep those lines working. This unit is sold in used condition.
