16. Tielines
Creating a Tieline
Arrows Represent Physical Connections
The arrows that appear in the ‘Graph’ section represent the physical cable that connects the two
devices. In order for a tieline configuration to work, the actual ports must be connected. For instruc-
tions on making connections to a physical port, refer to the device’s User’s Guide.
Figure 16-2. Tieline Graphic Representation
There are basic interface tasks you can perform in the ‘Graph’ section:
• Drag — To move an image in the ‘Graph’ field, left-click on the image, and while keeping the
mouse button depressed, move the mouse to “drag” the image to a new location.
• Draw tielines — To create a tieline, you “draw” an arrow between two devices. To draw an
arrow, click on the port you want in the downstream device. Keeping the mouse pointer button
depressed, move the mouse to the port on the upstream device being mapped. A line appears on
the screen between the two ports. You must start with the downstream device first.
• Activate arrow — To activate an arrow between devices, click on the arrow in the ‘Graph’ sec-
tion. This populates the ‘Virtual Levels’ and ‘Signal Types’ associated with that tieline connec-
tion.
Creating a Tieline
A tieline can be created and configured at any time. Once changes are saved, there is no “undo”
function; the configuration is permanently altered. To implement saved configuration changes, the
changes must be written to the NV9000 system controller for dispersal to connected devices. For
information on implementing changes, see
Implementing Configuration Changes on page 17.
If currently connected to the NV9000 system controller and NV9000-SE, configuration changes
take effect immediately. It is recommended that tielines be added off-line. That ensures that all set-
tings are correct before you go “live.”
