Definition

STATEMENT OF THE CLASS SUBJECT MATTER:

(A) Systems, processes and instruments for the two-way electrical transmission of intelligible audio information having arbitrary content over a link including an electrical conductor, between spaced apart locations, so as to enable conversation therebetween, and intended for the private use of a listener or a group of listeners. The term "intelligible" used above is intended to include the capability for transmission of speech or the like (e.g., music), rather than restriction to a specified audible signal, such as a bell or buzzer.

(B) Switching, signalling or signal transmission peculiar to, or specified as for a telephone or a telephone system, except for multiplex communications as indicated in Lines With Other Classes and Within This Class, below.

(C) Subsystems, elements and adjuncts peculiar to such transmission and not provided for elsewhere.

Lines with other classes and within this class

(1) Bi-directional audio communication is normally a duplex arrangement, and simultaneous audio transmission of a single conversation is in this class (379) and excluded from Class 370, Multiplex Communications, in the absence of some other particular multiplexing technique.

(2) With exception of voice signal duplexing as pointed out in (1) above, subject matter including multiplexing, particularly involving plural conversations, regardless of recitation of telephone limitations, is excluded from this class (379) and is classified elsewhere.

(3) Audible signalling for call alerting, or producing a signal having other specific content, such as bells, buzzers, etc., are classified elsewhere, even if nominally characterized as used in a telephone.

(4) Electromagnetic switches for automatic telephone switching type, per se, are classified elsewhere.

(5) Electrical connectors merely nominally characterized as for telephones, in the absence of additional telephone structure are classified elsewhere.

(6) Named communications or telecommunications networks absent recitation of telephone or voice limitation are not classifiable herein.

(7) The following terms when used in a communication system or instrument are considered to specify telephone equipment except as specified in (2) above with respect to multiplexing or in class or subclass search notes: dial tone - off-hook, handset - on-hook, hookswitch - ringback, howler - sidetone, intercom - switchboard, key set - switchhook, telephone line (used with switching system), tip and ring (leads)

RELATIONSHIP TO OTHER SPEECH COMMUNICATIONS CLASSES

This class (379) requires the capability for two-way spoken communications, or specified used of a telephone line, and subsystems peculiar to either of the above.

A mechanical telephone is classified elsewhere. See References to Other Classes, below.

All speech or telephone equipment which conceals message content despite interception or unauthorized reception of a telephone signal is classified elsewhere. See References to Other Classes, below.

Electrical speech processing system and apparatus, including for example, such systems as, megaphones, public address systems and hearing aids; and transducers such as microphones, earphones or loudspeakers and also includes either of a telephone microphone or receiver are classified elsewhere. See References to Other Classes, below.

Audio signal telecommunications by a modulated carrier wave not having telephone land line structure or limitations is classified elsewhere. See References to Other Classes, below.
