Digital Service Unit Components
A DSU cabinet holds up to four DSU cards and two FIMs. The DSU cards provide digital trunk
interfaces for public or private network access and specialized digital functions (such as
messaging, expanded conference, and ISDN service). The FIMs support the transmission of
voice and data signals between nodes.
The DSU cabinet consists of the following components:
•
Cabinet Frame: The DSU cabinet is separated into two shelves. Shelf 1 is located at the
bottom of the cabinet and Shelf 2 is located at the top of the cabinet (both shelves are at
the front of the cabinet). Shelf 1 consists of slots 1 to 6 and contains 2 FIMs and 4 DSUs.
Shelf 2 consists of two Peripheral Resource Cards (PRCs).
•
Power Supply: The 200 Watt AC power supply provides power for the cabinet. The power
supply fan cools the cabinet.
•
Peripheral Resource Cards: The peripheral resource cards provide additional circuitry to
support the distributed architecture. These cards are installed in Shelf 2, slots 1 and 6.
