CHAPTER 5  OPERATION TEST
LOOP-BACK TEST
LOOP-BACK TEST
A loop-back test is performed on the DTI card. At least two DTI cards are necessary. Operational
tests are performed by the clock within the MP.
STEP 1: Assign the system data for a performance test as shown in Figure 5-1.

STEP 2: Connect the cable for loop-back test.
(1) When using a twisted-pair cable:
Figure 5-2 shows an example of the cable connection when the 24DTI/30DTI cards are 
mounted in the AP05 and AP06 slot of PIM0.
