USING A COMBINATION OF SIDEFRAMING AND DOWNFRAMING
When expanding video inputs beyond 256 and video outputs beyond 16, a combination of sideframing and downframing must be used. Sideframing allows video inputs to be expanded beyond 256. Downframing allows video outputs to be expanded beyond 16. The maximum capacity of a
NOTE: When using
As viewed from the rear of the matrix bays, Figure 58 illustrates a matrix bay configuration containing sideframed and downframed bays that provide 496 video inputs and 32 video outputs. The configuration consists of a total of four matrix bays.

Figure 58. CM9760-MXB Sideframing and Downframing Example: 496 Video Inputs and 32 Video Outputs (496 x 32)
In a new system installation, multiple matrix bays are labeled to identify the location of sideframed and downframed bays in the installation, for example, labels 2A, 12A, 22A, and so on for sideframed bays and labels 2A, 2B, 2C, and so on for downframed bays. Figure 58 illustrates a four- bay configuration using a combination of sideframing and downframing:
•Bay 12A is sideframed to bay 2A, increasing the number of available inputs from 256 to 496. Bay 12B is sideframed to bay 2B.
•Bay 2A is downframed to bay 2B. Bay 12A is downframed to bay 12B, increasing the number of available outputs from 16 to 32.
For additional examples of configurations using a combination of sideframing and downframing, refer to Appendix B.
