3com CM 4000 User Manual

All destinations employing tie lines will be so indicated with a blinking “T” in the destination status display in the 1st character
position. When in single destination mode, the 1st character position of each level will also reflect tie line status with the  blink-
ing “T.”

Any time a Take is attempted that requires a tie line connection but none are available, the following display will appear show-
ing the name of the destination, its current source, and the attempted source:

1

         NO TIE LINES LEFT TO SWITCH PRODCTN4 to OuterSpc

  VTR_0123  VTR_0124  VTR_0125  VTR_0126  STUDIO_A  STUDIO_B  ENGINRNG  PRDCTN4

This display will remain for an undetermined timeout or until the CLEAR button is selected, which ever comes first. If the
take is to multiple destinations via multiple destination mode or a sequence, as much of the operation requested as is possible
will be performed. If multiple tie line requests were not fulfilled, multiple warnings will stack up and be displayed consecu-
tively.

As required, this tie line warning will appear during normal takes, overrides and sequences. When this condition occurs, all
levels of switching for the particular take will occur for those levels which can (those that do not require tie lines or still have
tie lines available). Sequences will execute all other takes that can be completed.
