Select the search icon ( ![Search icon.]()) and select a network site. To learn more, see [740b52df89fae046d62524302e4c21662b8dc071.dita](https://servicenow-prod.fluidtopics.net/kv0HyRowIgUDSGAOIAE9~w "Review, update, or create your network site records in the Telecommunications Network Inventory application. These records enable you to view the location-specific attributes for each network site, including the network centers, buildings, floors, and rooms where your equipment is located."). | | Site Z | Destination network site for this connection. Select the search icon ( ![Search icon.]()) and select a network site. To learn more, see [740b52df89fae046d62524302e4c21662b8dc071.dita](https://servicenow-prod.fluidtopics.net/kv0HyRowIgUDSGAOIAE9~w "Review, update, or create your network site records in the Telecommunications Network Inventory application.

Logical Connection form] {#logical-connection-form__table_htp_wkd_wrb} **Related tasks** * [Define the logical connection details](https://servicenow-prod.fluidtopics.net/btxyc~cnAmvUqQ6M1tE79g "Review, update, or create a network asset instance for a logical or virtual port connection on your network interface cards. You define these attributes so that you can track and manage your network assets in the Telecommunications Network Inventory application.") ## Logical Connection form - Configuration {#ariaid-title3} The Configuration section in the Logical Connection form enables you to create a logical connection. {#logical-connection-configuration__table_f3c_dmd_wrb__entry__2} | Field | Description | |-|-| | 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](https://servicenow-prod.fluidtopics.net/OIC_ntQo5klI24LuaLB9fg "Review, update, or create a network instance for a network interface that controls the signaling and management functions between your networks. You define these attributes so that you can track and manage your network instances in the Telecommunications Network Inventory application."). | | 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. {#logical-connection-configuration__ul_tgq_jzy_25b} | | 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. {#logical-connection-configuration__ul_jrs_21y_ksb} | | Port Z | Network interface that is used in the Port Z connection. Select the search icon (![Search icon.]()) and select a network interface.

You define these attributes so that you can track and manage your network instances in the Telecommunications Network Inventory application."). | | 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. | [Table 2.
