Cross-section

In the KeyNettoolbar, click Cross-section  to 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-section form 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-section  form displays information on the selected telecom premises, such as identifier, 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 section on the form. 

Search functions on the Cross-section form

There are several options for opening telecom premises on a form, such as using its identifier, using the Pick from maptool, or clicking Pick from telecom premisesform. The available search criteria include all the fields of the telecom premises form, and search criteria can be entered in full or partially with % as the wildcard character. 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 devices activated by default.

You can also retrieve telecom premises based on the device identifier. Use the Device field to retrieve to the Cross-section form all the telecom premises that include the device identifier entered as a search criterion. The Device field is active when the form is empty, or when you click Clear.

Compare logical cross sections

You can view several different cross-sections at the same time by using the Compare cross-sections tool. 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. 

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

• 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. 

Devices / Cable filtering

In the top-right corner of the Devices section, 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 section, click Clear device filterto remove filters.

Connectors

The columns in the Connectors list may include the following:

The colours on the connection list of the Cross-sectionform indicate the usage state of the connector in question:

Ready to be connected is used if the TTMi interface is in use. 

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:

Changing logical reservations for connectors

On the Cross-section  form, 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 reservation in the menu displayed when you click the right mouse button. Except for the Connectors section, all other sections on the Cross-section form 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

To start the release of a circuit reservation, select the reserved connector on the list and click Release circuit reservation  in the tool bar at the bottom of the form. You can also activate this function by clicking a connector with the right mouse button (Release logical circuit reservation).

You will see the following question: Are you sure you want to release the circuit´s reservation? If you answer Yes, the reservations for the selected connector and connection will be removed from the circuit in question.

Filtering connectors

In the top-right corner of the Connectors section, click Connector filter . Filter connectors based on the Connector, Connector type, Owner, Remarks, Circuit, Inst. address, Other end, Other end address, Other end type, Connector range, Const. State, Service, Usage state, Customer, Length and Other end name. To view only connectors that are not reserved for circuits, select the Free only checkbox. Select or enter the filters and click Update to view the filtered connectors on the Connectors list.
