FAULT REPAIR PROCEDURES

4.UNIT FAULT

This section explains the fault repair procedure in a case where any of the faults shown in Table 5-6has oc- curred to all the line/trunk circuit cards mounted in a specific unit. Figure 5-4shows the range of units.

Table 5-6 Unit Fault Situation

FAULT SITUATION	REFERENCE SECTION

Noise, one-way speech, no tone.	Section 4.2, Unit Fault - Fault Related to Speech
Even if dialing has been made, dial tone does not stop.

Dial Tone cannot be heard.	Section 4.3, Unit Fault - When Dial Tone (DT)
	Cannot Be Heard

MUX card has become faulty and, as a result the CPU has changed	Section 4.4, Unit Fault - ACT-Side MUX Card Is
over.	Faulty and System Has Changed Over
