DEFINITION

Classification: 370/241

DIAGNOSTIC TESTING (OTHER THAN SYNCHRONIZATION):

(under the class definition) Subject matter wherein at least part of a multiplex system is to be evaluated for its performance.

(1) Note. This subclass may include a sole monitoring operation, i.e., a terminal which displays or indicates the operating state of the multiplex communication system or element.

(2) Note. Testing for the purpose of synchronization in the multiplex communication via time channels is not classified in this subclass.
