SELECTING (switches, relays, selectors H01H; electronic switches H03K 17/00) [2013‑01]
NOTE
-
This subclass covers:
- methods, circuits, or apparatus for stablishing selectively
a connect ion between a desired number of stations (normally
two), or between a main station and a desired number of
substations (normally one) for the purpose of transferring
information via this connection after it has been established;
- selective calling arrangements over connections already
established.
In either case, the connection may be made by means of electric conductors or electromagnetic waves.

In this subclass, the following terms or expressions are used with the meanings indicated:
- "subscriber" is a general term for terminal equipment, e.g. telephone for public use; - "substation" means a subscriber or monitoring equipment which may connect a single subscriber to a line without choice as to subscriber; - "satellite" is a kind of exchange the operation of which depends upon control signals received from a supervisory exchange; - "switching centres" includes exchanges and satellites.
