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.

STEP 3: Turn on the operating power. Confirm the state of the lamps on the two 24DTI cards or
30DTI cards. See Ta b l e  5 - 1 and Table 5-2.

NORMAL FAULT CAUSE ACTION
RU N F la s h
(120 IPM)On or Off Abnormal 
operation of DTI 
cardConfirm the programming data: 
CM05, CM07 YY=01.
Check to see if the SENS 
switch is set as per the AP 
number (04-15, 20-31) 
assigned by CM05.
Reset the MB switch 
(Down→Up→Down)
If the fault cannot be cleared, 
replace the card.
CRC Off On Bit Error Rate 
exceeds the 
predetermined 
valueCheck the receive line and 
external equipment.
Replace the remote DTI card.
PCM Off On No PCM signals 
arrive from the 
distant officeCheck to see if the DTI cable is 
correctly connected.
Plug and unplug the DTI card.
Repeat this two or three times.
FRM Off On Frame Alignment 
signals from the 
distant office can 
not be receivedCheck the receive line and 
external equipment.
Replace the remote DTI card.
RMT Off On Frame Alignment 
signals cannot be 
sent to the remote 
PBXCheck the transmission line 
and external equipment.
Replace the DTI card.
AIS Off On Remote PBX is in 
the loop-back testCheck the switch settings of the 
remote DTI card.1
