ONTROLLER
(MFC)
The matrix frame controller, located on the right front of the unit, is illustrated in Figure 6-6. For
every frame type, at least one Matrix Frame Controller (MFC) is required. The function of the
frame controller is to determine frame size, level, input offsets, output offsets, plus other physical
characteristics of the frame hardware. Both PESA’s PRC protocol and NET PRC protocol are
available to the MFC. With the NET-PRC protocol, the MFC has the ability to communicate to a
system controller via Ethernet connection. More features include SNMP support and redundant
MFC cards with auto changeover.

Matrix Frame Controller
The MFC has the ability to provide dual operations. By setting each MFC with its own Ethernet
address, updates and active switching can be done in parallel that allows immediate crossover
during a card failure or network interruption (refer to Chapter 8, Appendix A for details on
Ethernet configuration options).
