    Abstract - (Show below) - (Hide below)

    Specifies mechanical and electrical requirements and tests for simple telephones for connection to a single exchange line of the public switched telephone network run by some licensed public telecommunication operators or attached systems. Does not specify requirements for apparatus for connection as extensions on any form of PBX. Does not apply to apparatus with control or switching of other voice circuits. Applies to apparatus for office, household and similar general indoor use. Includes annexes, tables and diagrams.
