1. In a method of replacing a faulty module in a module frame for a digital branch exchange, wherein:
- a faulty condition of the module in the module frame is indicated in accordance with an extent of an effect of the faulty condition, with at least one visual indicator element mounted visibly on the module;
an out-of service condition is indicated with one or more of the visual indicator elements once the module has been taken out of service; and
after a new module has been inserted in place of the faulty module in the module frame, a test-function performance condition and the subsequent in-service condition of the new module are indicated, as appropriate;
the method comprising the steps of;
pressing a repair key assigned to the module of the digital branch exchange for initiating a repair condition, wherein actions and control procedures required for taking the faulty module out of service are carried out, and for causing the new module inserted in the module frame to be automatically recognized; and
for initiating a test function and an automatic placement into service of the new module in dependence on a positive test result obtained in the test function.

Abstract
Different conditions of a module are indicated by means of at least one visual indicator element, for instance in the form of a light emitting diode, mounted visibly on the module. Pressing a repair key initiates a repair condition, in which the actions and control procedures necessary for taking the faulty module out of service are carried out, and also causes a newly inserted module in a module frame to be automatically recognized, prompts a test function and causes the new module to be automatically put into service upon passing a test procedure.
