    Summary of Physical Connection Creation subflow

    The Physical Connection Creation subflow allows the creation of a physical connection record in the Telecommunications Network Inventory application. It facilitates establishing a physical port connection on network interface cards, generating connection elements, and associating them with the physical connection. If a physical connection element is provided, it also creates and associates the corresponding connection element.

    Roles and Availability

    This subflow is accessible to users with the admin role, who can add it to a flow and configure its details. It is specifically utilized for inventory-related data operations within the Telecommunications Network Inventory application.

    Input Fields

    The subflow requires several input fields, including:

    • Interface A: Starting network interface (mandatory)
    • Interface Z: Ending network interface (mandatory)
    • Bandwidth: Specifies the bandwidth of the connection (mandatory)
    • Connection Type: Updates the associated product model (mandatory)
    • CI Relationship: Default set to Terminated::Terminated by (mandatory)
    • Physical Connection Elements: Optional sysid for added elements if the connection type is Cable
    • Strand Number: Cable number for the physical connection element (optional)
    • Allocate Pair: Option to create two connection elements using two strands (optional)

    Output

    The subflow generates the following outputs:

    • Physical Connection: Returns a glide record of the created physical connection.
    • CI Relationship with Interface Z: Provides the CI relationship for the ending network interface.
    • CI Relationship with Interface A: Provides the CI relationship for the starting network interface.

    The Physical Connection Creation subflow enables you to create a physical connection record in the Telecommunications Network Inventory application based on the input that you receive when you instantiate an inventory.

    Overview

    You can use the Physical Connection Creation subflow to create a physical port connection on the interface cards in your networks.

    This subflow also creates the connection elements and associates them to the physical connection.

    If you enter a physical connection element, this subflow creates the corresponding connection element and associates it to the physical connection.

    Roles and availability

    Users with the admin role can add a subflow to a flow and define the configuration details of the flow. This Flow Designer subflow is available in the Telecommunications Network Inventory application so that you can perform inventory-related data operations.

    Input fields

    The following table lists the input fields in the Physical Connection Creation subflow and their description.

    Table 1. Input fields of subflow
    Field Name Description Data Type Mandatory?
    Interface A Starting network interface where this logical connection is configured. Reference.Network Interface Yes
    Interface Z Ending network interface where this logical connection is configured. Reference.Network Interface Yes
    Bandwidth Bandwidth of the logical connection. Reference.Bandwidth Yes
    Connection Type Type of connection. This field information updates the product model that is associated with the physical connection. Reference.Physical Connection Model Yes
    CI Relationship Type of configuration item (CI) relationship. By default, the Logical Creation subflow sets a CI relationship to Terminated::Terminated by. Reference.CI Relationship Type Yes
    Physical connection elements sys_id of the connection elements that are added for the physical connections. If the physical connection has the Connection Type attribute as Cable, you can add the connection element. Click the add icon (Add icon.) to add a connection element. Array.String No
    Strand Number Cable number of the physical connection element.
    Note:
    The strand number must be less than or equal to the strand count in the physical connection.
    		 Integer No
    Allocate Pair

    Option to create two physical connection elements

    If you enter the strand number and select Allocate Pair, the cable uses two strands. One strand is a strand number and the other is strand number +1.

    		 True/False No
