ABSTRACT:
A telephone, for use in a key telephone system, has built-in test capability for verifying the operation of components in the telephone. The test capability is such that a relatively unsophisticated user can step through and conduct each of a plurality of separate tests. Interface to the tests is provided through the same switches and indicators on the telephone used for normal telephone operation. Status of certain test routines and components being tested is indicated, during the test mode of operation, on the telephone's regular indicator lamps.
