12.5 CTC Window
When you log into a single-shelf ONS 15454, the CTC window appears in node view (Figure 12-3). 
When you log into a multishelf ONS 15454, meaning that two or more ONS 15454 shelves are 
configured to operate as one node, the multishelf view (Figure 12-4) appears in the CTC window. The 
window includes a menu bar, a toolbar, and a top and bottom pane. The top pane provides status 
information about the selected objects and a graphic of the current view. The bottom pane provides tabs 
and subtabs to view ONS 15454 information and perform ONS 15454 provisioning and maintenance 
tasks. From the CTC window, you can display the other ONS 15454 views. In single-shelf mode, these 
are the network, node, and card views. In multishelf mode, these are the network, multishelf, shelf, and 
card views. 
TL1 Refers to a connection to the ONS 15454 
using TL1 rather than CTC. TL1 sessions can 
be started from CTC, or you can use a TL1 
terminal. The physical connection can be a 
craft connection, corporate LAN, or a TL1 
terminal.
