The Logical Connection form enables you to define a logical connection by describing its configuration and connection details.

Logical Connection form

The Logical Connection form enables you to describe the details for a logical connection.

Table 1. Logical Connection form
FieldDescription
Name Name of this logical connection The ServiceNow AI Platform uses this name to identify it in your network inventory.
Max percent over subscription Percent of subscription allowed for a logical connection with respect to the bandwidth.
Site A

Originating network site for this connection. Select the search icon ( Search icon.) and select a network site. To learn more, see product/tmt-telecom-network-inventory/task/define-tni-sites.dita.
Site Z

Destination network site for this connection. Select the search icon ( Search icon.) and select a network site. To learn more, see product/tmt-telecom-network-inventory/task/define-tni-sites.dita.

Logical Connection form - Configuration

The Configuration section in the Logical Connection form enables you to create a logical connection.

Table 2. Logical Connection form - Configuration
FieldDescription
Port A

Network interface that is used in the Port A connection. Select the search icon ( Search icon.) and select a network interface. To learn more, see Define the network interface details.
Bandwidth AtoZ

Total bandwidth capacity from Site A to Site Z for this network connection.
Planned date Projected date for the implementation.
Framing type Type of frame used in the connection. Select one of the following:
  • None
  • AMI (Alternate Mark Inversion) - A line coding scheme where zeros are represented by no voltage, and ones are represented by alternating positive and negative voltages.
  • B4ZS (Bipolar with Four-Zero Substitution) - A technique that replaces sequences of four consecutive zeros in a digital signal with a special pattern to maintain synchronization.
  • B8ZS (Bipolar with Eight-Zero Substitution) - Similar to B4ZS, but it replaces sequences of eight consecutive zeros with a special pattern to maintain synchronization in high-speed digital signals.
Protocol version Protocol version number.
Endpoint role
Endpoint role that is associated with the service endpoint for this network asset. An endpoint role is the function that is served by the endpoint of the service that you’re providing. Select one of the following options:
  • ROOT or LEAF endpoint role, as defined by the Metro Ethernet Forum (MEF).
  • --None-- for no assigned endpoint role.
Port Z

Network interface that is used in the Port Z connection. Select the search icon (Search icon.) and select a network interface. To learn more, see Define the network interface details.
Bandwidth ZtoA

Total bandwidth capacity from Site Z to Site A for this network connection.
Cost

Cost of this network asset.
Distance

Route length of this connection, expressed in the unit of measure that you select in the Unit field.
Unit
Unit of measure in which you’re expressing the route length of the connection in the Distance field. Select one of the following options:
--None--
No distance measurement expressed for the connection route length.
Miles
Distance is expressed in miles.
Kilometers
Distance is expressed in kilometers.
Feet
Distance is expressed in feet.
Meters
Distance is expressed in meters.
