The integrated tests are sufficient to test and isolate the faults in the interface.Chapter 8. Test Procedures for ISDN U-Interface The CRP command TST-TRM is used to perform the tests on the U-interface in C-DOT DSS.1. On execution of CRP command. the following parameter entry sheet is displayed on the screen. A reference test set up for acceptance testing of ISDN services is shown in figure 8. as explained in the document “Exchange Operations”. The EOC functions are used to support the functional testing on LT in the exchange as well as NT in the customer premises up to S-Interface.2.

The test sets 609 is used to monitor the characteristics of cable pair. after The status of a BRL card can be modified to “Out of Service” by using CRP command FRC-TRML-CARD-OOS. the interface will be deactivated with its status. its status can be modified to “In service” by using CRP command FRC-TRML-CARD-INS without testing or PUT-TRML-CARD-INS after successful testing. Creating a Reference Test Circuits (TLC) in C-DOT DSS The TLC is created to simulate the functions of LT when tests set 608 is executed to verify the functioning of NT up to S-Interface. Procedure for Testing of ISDN Termination Card In case. it simulates the functions of NT to test the LT in the exchange. The card can be tested using CRP command TST-TRML-CARD with parameters as : RTN-COD RPT-FMT REPEAT TML-CRD-TYP TST-SET CARD-SLOT : : : : : : G B NO BRI 605 or 606 The status of the BRL card can be displayed by using CRP command DISPLTRML-CARD-STATUS with parameter as : TML-CRD-TYP CARD-SLT : : BRI The status of the card can be displayed as INS-NRM.3.4. more than 50% interfaces corresponding to a Interface Card is reported as faulty. successfully.
