The commutation interface makes it possible to clearly see all commutation in a communications installation/splice closure, both between objects and with equipment.

Tools are available for adding objects and performing commutation directly in the scheme. When you click an object in the scheme, the corresponding menu with additional actions appears.

When you click two objects that can be connected one after another (fibers/cores/adapters/ports), a menu appears for commutation/splicing of those objects.

Commutation is shown as a line between two objects in the colors of the two involved fibers/cores, or in yellow when equipment adapters/ports are involved. The line has three points; clicking them lets you shift the route used to draw this line. If the coordinates of the commutation point are not changed, the system will try to align the lines to the grid.

When an already commutated object is selected, you can break the connection for this object or reset the coordinates of that connection (useful if they were changed).

When viewing the scheme, all ports/adapters/fibers that are connected to equipment at their end points have white arrows in the scheme. Hovering over them shows a hint about the connection and lets you view the equipment card.

For commutation of cable lines with many fibers/cores, or ODFs/distribution frames with many adapters, there is a so-called "Commutation master".

Planned objects are displayed in the scheme slightly differently from actually existing objects. See "Planning".

The commutation scheme in large communications installations can be substantial in size, so when printed it is scaled to A4 format. However, during printing the scheme is exported to a PNG/SVG image, which can be saved and then printed at the required size or used in other software.

Starting from version 3.17, it is possible to undo operations in the commutation scheme. Many actions can be undone in the commutation scheme of a communications installation: changing the position of cables, distribution frames, devices, their direction, commutation, and so on. The "Ctrl+Z" key combination is supported.

Also, starting from version 3.17, the commutation scheme can display text information on cable line fibers about the end point where the fiber is connected. This makes it possible to quickly see where all fibers go and whether they are occupied while viewing the scheme.

In the commutation scheme of a communications installation, you can immediately change the note on a distribution frame/ODF.

Also, the switch port menus now include a link to the general commutation menu for that port.

Starting from version 3.18:

The commutation scheme now supports cancelling commutation of all fibers/cores of cables/distribution frames between each other.

Undo actions in the commutation scheme of a communications installation now include the ability to undo a commutation break.
When recommutating in the commutation scheme, cancelling the commutation operation also restores the previous commutation.

Colored "commutation arrows" have been returned to the commutation scheme. They show which equipment is currently active/inactive.

The commutation scheme displays ONU RX signal levels (dBm) for connected ONUs on splitter ports.

When a fiber/patch cord is clicked in the commutation scheme, it changes not only its thickness but also its color.

Added the ability to commutate all free fibers/cores of a cable line or ODF/distribution frame adapters to another object. In other words, mass commutation is performed only between unoccupied objects.

Also, in the commutation scheme, the customer's ONU signal level is displayed in the customer tooltip.

UPLINK/DOWNLINK ports are separated for equipment.

When a commutation line is clicked in the global commutation scheme, the entire commutation route of that line is highlighted at once.

Starting from version 3.19:

Added the ability to change a cable line label directly in the commutation scheme from the menu of that line.

For cable lines, splitters, and distribution frames, commutation can be cleared for the entire object at once (previously only one side of the object could be cleared).

If a cable line starts and ends at the same object, both of its ends are visible in the commutation scheme, including in the commutation master.

Starting from version 3.20:

A new connection type has been added: "Planned object" in the commutation scheme.

Starting from version 3.21:

Commutation scheme snapshots are displayed on the main scheme and are also generated directly during commutation/break operations on a communications installation. They are generated and stored in .svg format, which additionally allows them to be used in other documents/programs.
