The Model 7076 is a general purpose matrix switching card that consists of two independent 412 switching matrices. Each matrix has two switched circuits (HI and GUARD). The four row signal paths are connected through jumpers to the general purpose analog backplane in the Model 707A switching mainframe. This provides the interconnect between cards for column expansion (424, 436, etc.). The jumpers can be removed to isolate any matrix. The columns of the two matrices on each card can be tied together with on-card jumpers for expansion to an 812 matrix. Connections to the matrix are through standard 25-pin D connectors for mass termination. There are two column connectors, one for each bank, and one row connector.
