8.5.2 Network View
The graphic area displays a background image with colored ONS 15454 SDH icons. A Superuser can set
up the logical network view feature, which enables each user to see the same network view.
The lines show DCC connections between the nodes. DCC connections can be green (active) or gray
(fail). The lines can also be solid (circuits can be routed through this link) or dashed (circuits cannot be
routed through this link).
There are four possible combinations for the appearance of DCCs: green/solid, green/dashed, gray/solid,
or gray/dashed. DCC appearance corresponds to the following states: active/routable,
active/nonroutable, failed/routable, or failed/nonroutable. Circuit provisioning uses active/routable
links. Selecting a node or span in the graphic area displays information about the node and span in the
status area.
The color of a node in network view, shown in Table 8-10, indicates the node alarm status.
Table 8-11 lists the tabs and subtabs available in network view.
Table 8-10 Node Status Shown in Network View

Yellow Minor alarms
Orange Major alarms

Gray with Unknown# Node initializing for the first time (CTC displays Unknown#
because CTC has not discovered the name of the node yet)
