A modular communications cable assembly comprises first and second connectors, each having an elongated array of electrical contacts, and high-speed (e.g., data) and low-speed (e.g., voice) twisted wire pairs extending between the first and second connectors and terminated to the electrical contacts. Electrical contacts are skipped (or left empty) between the high-speed wire pairs to reduce cross-talk., but no electrical contacts are skipped between the low-speed wire pairs. An electrically conductive member with pins may be used to electrically couple the skipped contacts together to further reduce cross-talk. In another aspect, a modular communications cable assembly provides a plurality of communication circuits to a cluster of workstations. The cable assembly comprises an upstream connector and at least one downstream connector, with a plurality of high-speed cable segments and at least one low-speed cable segment extending between the upstream and downstream connectors. Each high-speed cable segment contains a set of twisted wire pairs for high-speed communication, and the at least one low-speed cable segment provides a plurality of sets of twisted wire pairs for low-speed communication. Each communication circuit comprises one set of twisted pairs from the high-speed cable segments and one set of twisted pairs from the at least one low-speed cable segment. Colors are used to facilitate the proper joining of cable assemblies, e.g., black connectors are joined to red connectors. A circuit breakout assembly (FIG. 13) is used and includes a body, an in-feed connector and a plurality of breakout connectors for providing communication circuits to a cluster of workstations.
