Switching
The following components provide the switching capabilities of the S535.
Model 707B Switch Matrix Mainframe
The 707B Semiconductor Switch Matrix Mainframe is a programmable switch for connecting signal
paths in a matrix structure. The six-slot mainframe accepts any combination of compatible plug-in
matrix cards. Model 7530 matrix cards are used in the 707B in S535 systems.
