NOTE
-
This subclass covers :

- telephonic communication systems combined with other
electrical systems;
- testing arrangements peculiar to telephonic communication
systems.

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 type of exchange the operation of which
depends upon control signals received from a supervisory
exchange;
- "switching centres" includes exchanges and satellites.
