These requirements cover telecommunications-circuit accessories, such as jack and plug assemblies, quick-connect terminal assemblies, telephone wall plates, telephone extension cords, cross-connect terminal-block assemblies, maintenance terminal modules, terminal enclosures, cable-splice enclosures, network-interface devices, wire-guide assemblies, and connector boxes.

These devices are intended to be used in telecommunications networks that have an operating root-mean-square (rms) voltage to ground less than 150 volts and installed or used in accordance with the National Electrical Code, ANSI/NFPA 70.

These requirements do not cover telephone equipment such as telephone answering devices, residential telephone instruments, telephone dialers, cordless phones, key systems, and private-branch exchange equipment that is covered by the Standard for Telephone Equipment, UL 1459. Also, these requirements do not cover:

1. Telephone protectors that are covered by the Standard for Protectors for Paired Conductor Communications Circuits, UL 497, and
2. Secondary protectors.

These requirements do not cover cellular telephones or other receiver/transmitter-type devices. Equipment of this type is covered by the Standard for Radio Receivers, Audio Systems, and Accessories, UL 1270.
