The path finding
§
software option allows two or more Venus, Trinix, or later routing switchers to operate as a system, where
one switcher can access the other’s inputs through a number of tie lines. For example, Figure 5−152 shows a facility with a
large, central distribution switcher and a smaller switcher normally used only within the news department. By placing both
switchers under control of the Jupiter system, and by adding tie lines, the main router can access the news department’s inputs.
In this example, VT21 can be switched to output 55 of switcher “MAINROUT” with one command: the system will first
switch VT21 to one of the tie lines leading from “NEWSROUT” to “MAINROUT,” then it will switch that tie line signal to
output 55 of “MAINROUT.”

Path finding is not the same as three−stage switching. Path finding involves discrete switchers connected by a small number
of tie lines, the number of which strictly limits the inputs available at the downstream switcher.
