Cross-section

In the KeyNettoolbar, click Cross-sectionto open the Cross-section form. You can also open this form through the telecom premises’ list of Devices or through the list of Telecom premises of the circuit section by clicking the right mouse button and selecting it in the displayed menu. 

The Cross-sectionform displays the connections between the connectors in the selected telecom premises and device and information on the related circuits. This form is also used for reserving a connector or sub-circuit for a circuit, for switching pairs, and for releasing a reservation. 

Cross-section form

The Cross-sectionform displays information on the selected telecom premises, such as identification, name, type, usage state, address, ownership, and the devices on the telecom premises. The connectors and related connections of an activated device are listed in a separate Connectors list on the form. Threads details can be examined on the Threads list. 

Search functions on the Cross-section form

There are several ways to open telecom premises in the Cross-sectionform:

• By entering the premises Identifier directly
• By using the Pick from maptool
• By clicking Pick from telecom premises. You can search using any field available in the Telecom premisesform. Search criteria can be entered either fully or partially, using the % character as a wildcard.

Searching based on a device or cable identifier

Additionally, you can retrieve telecom premises based on a device or cable identifier. To do this, enter the identifier in the Device / Cable field on the Cross-sectionform . This will return all telecom premises containing the specified device or cable to the Cross-sectionform. The Device / Cable field is active when the form is empty or after clicking Clear.

If the Enable Device / Cable Filter checkbox next to the Device / Cable is selected, the search conditions are applied to the Device / Cable filtering and list, automatically highlighting and preselecting matching rows. If the checkbox is not selected, the search conditions do not affect the Devices / Cables list or identification fields. 

If the checkbox is not selected, the search criteria do not affect the Devices / Cables list or the identifier fields, but instead apply to the search field located below the Devices / Cables list. The search field for the Devices / Cables list is always automatically populated when the user searches for existing telecom premises locations using a device or cable identifier. In this case, the rows related to the original search criteria are highlighted in the Devices / Cables list, and the first match is automatically selected. 

Pin/Unpin toggle

The Pin/unpin toggle buttons manage whether the Connector and/or Thread lists are open automatically.

Pin selected:

The system respects the user's choice to keep the lists open or closed. They will not be automatically enabled when a device or cable is selected.

Unpin selected:

The system will automatically display the content of the associated Connectors and/or Threads lists whenever a device or cable is selected in the Cross-sectionform.

Compare logical cross-sections

You can view several different cross-sections at the same time by using the Compare cross-sectionstool which can be enabled from the form's toolbar.

This tool enables simultaneous comparisons such as comparisons between various devices, their connectors, and circuits in some specific telecom premises. The Cross-sectionfrom which the Compare logical cross- sections function is activated will become a so-called primary form, and the Cross-section forms used for comparison will be named in accordance with the header >Cross-section.

Devices / Cables 

The Devices / Cables list includes information on the device, such as the device identification, type, class, usage state, and pair range. The column named Free indicates how many connectors in the device in question are available. The OE telecom premises column displays the telecom premises that the device in question can access.

The visibility of devices and cables in the Devices / Cables grid can be determined before a search by using the Show devicesand Show cablesbuttons in the upper right corner of the grid. Only Show deviceis activated by default. 

The Devices / Cables displays the hierarchy of the selected device next to the list title.

You can also use the Searchfunctionality to look for devices and cables related to the telecom premises. The corresponding text written in the field is highlighted on the hierarchy below. Turning to next page of the form resets the Searchfunctionality. 

• Turning on Case sensitive activates a search that have strict checking of lower and upper cases. For example, if you search the word "in use" the system will only search for that desired word and will exclude words like "In use" from the search because it has an upper case letter.   
• The Regular expression allows you to search for specific patterns, as opposed to certain terms and phrases. 

Device / Cable filtering

In the top-right corner of the Devices list, click Device/Cable filter. Filter devices based on Identification, Type, Class, Usage state, Other end, Service and Connector and cables based on Identification, Type, Class, Usage state, Other end, Length and Pair / Thread. Select or enter the filters and click Update to view the filtered devices on the Devices /Cables list.      

When devices are filtered, the form functions are applied to a limited group of devices. In the top-right corner of the Devices / Cables list, click Clear device filterto remove filters.

Connectors

The connectors and related connections of a selected device are listed Connectors list.

The columns in the Connectors list may include the following:

The Connectors list highlights those device connectors that involve a multi-use (meaning two or more circuits reserve the same device connector) with thesymbol. On the Circuit column, you can also see the amount of reservations in brackets:

The colours on the list indicate the usage state of the connector in question (Ready to be connected is used if the TTMi interface is in use):

Changing logical reservations for connectors

On the Cross-sectionform, you can change the circuit reserved for a device’s connector, or you can change the circuits to go through the same device’s other connector that has no circuits.

On the form, select the connector with a circuit or circuits. Alternatively, you can also select an individual circuit row by opening the connector’s circuits for viewing.

Then, click Change of logical reservationin the menu displayed when you click the right mouse button. Except for the Connectors list, all other lists on the Cross-sectionform will be disabled.

Next, in the same device, select a connector that has no reservations. Click the right mouse button and select either Accept reservation change or Cancel reservation change. Select Route follower to check the route.

Releasing a connector reservation
