The MGX 8220 Shelf Controller (ASC) is a two-card set consisting of an ASC front card and an
ASC-BC back card. The shelf may contain a single ASC card set or a dual (redundant) card set. The
cards are installed in slots three and/or four. An illustration of the ASC card set is provided in
Figure2-11.
The function of the ASC is to provide a user interface to provide overall control, configuration, and
management of the shelf. The ASC interfaces with the other cards in the shelf through the cell bus
on the one side and with the user through console ports on the other side.
