Connections management (logical)

On the Connections managementform, with the Logical state being selected, you can create, cancel and edit KeyNet connections. Logical connections are connections between the connectors of devices in telecom premises. The two windows (lists) of the Connections managementform display the devices in telecom premises. You can select different telecom premises to be displayed on the lists. Browse through the tree diagram to find all possible connectors and the connections below them.

CT means connection type. The various connection types include Cross-connection (CC), Internal connections (INT), and External connections (EXT). The basic functions of this form are explained in the chapter Connections management.

The available functions depend on whether you open the context menu (with the right mouse button) over a device, connector, or connection. From the Open in menu, you can access the Device form, Telecom premises device list, Logical cross-section, Route follower, or the Circuit form for reserving circuits. Click Affected area to open a Route follower form pre-completed with the selected device’s connectors and cables connected to the connectors. The route follower highlights the connection routes that are connected to the selected device either directly or over logical cross-connections.
