Engineering Name – Any combination of up to 8 alphanumeric characters may be used to
assign the Engineering Name to the tie-line.
Nickname - Any combination of up to 8 alphanumeric characters may be used to assign the
Nickname to the tie-line.
Name – This field is essentially a free text space where you may enter a name up to 32
characters in length for the source. This name is only displayed on this configuration screen
and may be used to more clearly comment the tie-line function.
8.9.8.2 Defining a Tie-Line
Remember that a tie-line is a hard-wired external connection between a dedicated physical
output (destination) from one level and a dedicated physical input (source) on another level. It
is important to clearly understand that a tie-line is a physical connection made external to the
router using cable attached to physical BNC connectors on the rear panel of the router. In order
to configure a tie-line it is necessary to program the destination and source as follows:
Output Level Name – This entry field contains a pull-down menu containing all the levels
defined in the configuration. Move the cursor to and click on the switching level from which
you wish to derive the signal routed to the tie-line.
Output Number – Enter the number of the physical output connection from the level entered
above from which you wish to derive the signal routed to the tie-line.
Input Level Name – This entry field contains a pull-down menu containing all the levels
defined in the configuration. Move the cursor to and click on the switching level you wish to
receive the signal from the tie-line.
Input Number – Enter the number of the physical input connection of the level entered above
you wish to receive the signal from the tie-line.
In our example configuration screen, we have assigned the name NTSCSDI1 to a tie-line
deriving its source signal from physical output 28 on switching level VIDEO and directing its
destination signal to physical input 28 on switching level SDI.

The Source-Dest Block Configuration Screen, Figure 8-40, allows you to selectively block any
source from being switched to a designated destination. Clicking on the Source-Dest Blocks
parent entry in the Command Screen Window brings up a clean copy of the working screen.
Note that the screen has three areas:
Destination Name – This field is where you enter the name of the destination to which you
wish to apply source blocks. There are two way to enter a destination name. You can simply
type the name of the destination or you can copy and paste the name from a cell of the
destination screen.
Blocked Sources – Sources you wish to block from access by the named destination are listed
in this column.
Available Sources – This column contains a listing of all the sources which may be switched to
the named destination.
