FAULT REPAIR PROCEDURES

13.INTEGRATED SERVICE DIGITAL NETWORK (ISDN) LINE FAULT

This section explains the fault repair procedure when any of the faults shown in Table 5-12occur to a specific ISDN.

Table 5-12 ISDN Line Fault Situation

FAULTY SITUATION	REFERENCE SECTION

A specific CCH/CCT card is faulty.	Section 13.3, Specific DCH/PRT Card Is Faulty

When the signal transmission line is a digital line, transmitting/	Section 13.4, Fault of DCH, DTI, and Related Flat
receiving of control signals cannot be performed.	Cable

13.1 Check Point

When repairing an ISDN Line fault, consider the following items:

(1)Check alarm lamps on the DCH or PRT circuit card.

(2)Refer to Figure 5-24, and check the cable connection.

13.2 ISDN Line Control

The DCH/PRT circuit card controls the signal link (digital) of the ISDN line and transmits/receives call processing information.

The signal link controls permit normal transmission and reception of call processing information. Figure 5-24shows the ISDN line control route.
