What is the term used for the cabling from the telecom closet to the main cross connect or computer center?

The term that accurately describes the cabling from the telecom closet to the main cross connect or computer center is "backbone cabling." Backbone cabling serves a critical role in connecting various horizontal cabling subsystems and distribution devices to the main networking equipment. This type of cabling typically runs between different buildings or across floors within a building, facilitating the aggregation of network connections and serving as a backbone for the entire networking infrastructure.

In contrast, intermediate cabling generally refers to connections that occur between the main distribution area and intermediate distribution areas. Distribution cabling pertains to the cables that run from these distribution areas to the work areas or end points, while link cabling refers to the connection established between two end devices. Each of these terms describes specific functions and locations within the overall cabling hierarchy, but backbone cabling is distinctively focused on the higher-level connections that tie the main components of a network together, which is why it is the correct answer for this question.
