Implementing Your System Plan
An effective routing switcher system requires careful planning. A complex routing switcher system can be easily
mapped using an NK-VRC. All that is required is:
• a list of all the source and destination equipment and resources, identified as virtual sources or destinations
• the inputs and outputs that are physically connected to each routing switcher
• the level of each routing switcher
The following process for setting up the NK-VRC is recommended:
Figure 2.3 Flow chart for setting up the NK-VRC
Communication Overview
The control panels and devices send a virtual switch request message to the NK-VRC. The NK-VRC translates this
virtual request to physical requests, then sends these to the routing switchers. The routing switchers recognize the
requests, set the crosspoints, then send physical responses to the NK-VRC. The NK-VRC translates these physical
responses to virtual responses, then sends these to the control panels and devices.
Data Storage
The control panels and devices store information on the menu, destination, level, breakaway, and machine control
status. The routing switcher stores the crosspoint status in its internal memory. The NK-VRC stores mapping
information that correlates virtual sources and destinations with physical inputs and outputs, and the virtual status.
When the
routing switcher system is powered up, the routing switcher restores its crosspoint status. The control
panels
and devices request the status of the routing switcher via the NK-VRC. The NK-VRC switches the routing
switchers to match the stored virtual status, and also sends the virtual status to the control panels and devices.
Establishing the virtual status may take several minutes, especially if the mapping table has many entries for
unassigned crosspoints.
